## 4. Technical guidance

- Standard flow Nm3/h vs actual suction m3/h - the single most common sizing error in
  booster applications. Cylinder size depends on actual suction volume, not on Nm3/h.
- Gauge pressure bar(g) vs absolute pressure bar(a): mixing them on a low-suction-pressure
  project causes order-of-magnitude errors.
- Number of compression stages follows from total pressure ratio, discharge temperature
  limits, rod load limits and the available cylinder range - not from a fixed rule.
- Gas medium drives material, sealing, lubrication and safety design: hydrogen needs
  dedicated leakage and material assessment; CO2 needs phase and water-dew-point control;
  oxygen and chlorine need dedicated cleaning / corrosion design.

## 5. Frequently asked questions (full answers)

Source: https://tukecompressor.com/en/frequently-asked-questions

### 1. What is a process gas compressor and how is it different from an ordinary air compressor?

A process gas compressor is engineered around a specific gas and a specific duty inside a customer production process, rather than around ambient air. The gas composition determines the molecular weight, compressibility factor, corrosion behaviour, dew point and hazardous-area classification; the duty fixes flow, suction and discharge pressure, temperature and turndown. The consequence is that a process compressor is custom designed for its gas and operating envelope, while an ordinary industrial air compressor is a catalogue product working between roughly 7 and 13 bar(g) on air. This is why a natural gas, hydrogen, nitrogen or CO2 machine needs different materials, sealing, lubrication, cooling, separation and safety interlocks from an air machine.

### 2. What is the difference between Nm3/h and actual suction m3/h, and why does it matter?

Nm3/h is a mass-referenced flow measured at a defined standard state, while actual suction m3/h is the real volumetric flow entering the first-stage cylinder at the actual suction pressure and temperature. Cylinder bore, stroke and speed are dimensioned on the actual volumetric flow, not on the standard flow. The conversion is Qs = Qn x (Pn/Ps) x (Ts/Tn) x (Zs/Zn), with absolute pressures and absolute temperatures. On booster applications where suction pressure is low, the two numbers can differ by a factor of five or more. Sizing a cylinder on the standard figure is the most common and most expensive error in this business: the machine will simply not pass the contracted flow.

### 3. Why is gauge versus absolute pressure such a critical detail on low suction pressure projects?

Because at low suction pressure the suction-to-discharge ratio changes dramatically depending on the reference. A suction of 0.1 bar gauge is about 1.1 bar absolute, while 0.1 bar absolute is roughly 0.9 bar below atmospheric. The resulting pressure ratio, discharge temperature and required cylinder displacement differ by an order of magnitude. Every process gas compressor enquiry should state pressures explicitly as bar(g) or bar(a). Thermal calculations always use absolute pressure.

### 4. How many compression stages does a process gas compressor need?

The number of stages follows from four constraints rather than from a fixed rule: the total absolute pressure ratio, the permissible discharge temperature of the gas, the allowable rod load on the frame and the cylinders actually available. As a first estimate the ideal stage pressure ratio is r = (P discharge / P suction)^(1/N) with equal ratios per stage, but the final arrangement must also balance cylinder bore, inter-stage pressure drop, material pressure rating and the rod load of each throw. Raising the stage count lowers the temperature rise per stage and reduces the load swing; it also adds intercoolers, separators and drains. A design that needs an extremely high ratio in one stage is a signal to re-examine the stage count, the inter-stage pressure split or the cylinder clearance rather than to simply enlarge the bore.

### 5. How is discharge temperature controlled?

Discharge temperature is mainly a function of pressure ratio and the polytropic exponent of the actual gas: T2 = T1 x r^((n-1)/n). It is controlled by limiting the ratio per stage, by inter-stage cooling, and by keeping suction temperature low. Hydrogen, CO2 and heavy hydrocarbon mixtures must use their real gas properties rather than air values, because the exponent and compressibility factor differ substantially. Excessive discharge temperature is normally a symptom: a leaking valve, a fouled intercooler, an abnormal gas composition or a gas that has been re-routed through a bypass will all raise it. High-high discharge temperature is always a trip, not an alarm to be ignored.

### 6. Which gas media do you build compressors for?

Natural gas and CNG, oilfield associated and wellhead gas, nitrogen, hydrogen, carbon dioxide, biogas and biomethane, propylene and light hydrocarbons, ammonia, argon, oxygen, and corrosive process gases such as hydrogen chloride by dedicated project design. Each medium has its own material, sealing, lubrication and safety logic. Hydrogen, for example, leaks through very small clearances and needs dedicated material assessment and leakage detection; CO2 is strongly affected by phase behaviour and water content; oxygen and chlorine require special cleanliness and corrosion design that cannot be copied from a natural gas solution.

### 7. Can you supply an oil-free compressor?

Yes. Oil-free (non-lubricated) cylinder construction with appropriate piston rings and packing is used where the gas must not be contaminated by lubricating oil, for example nitrogen for new-energy manufacturing, certain hydrogen services, oxygen and some food and pharmaceutical related gas duties. Oil-free construction changes the ring and packing material selection, the allowable piston speed and the cooling arrangement, so it is always designed for the specific gas and duty rather than being a simple option on a standard machine.

### 8. What is included in a typical compressor package?

A project package normally includes the compressor main unit, the driver with coupling and guard, the gas system with inlet, inter-stage and discharge piping, valves, check valves, safety valves, pulsation dampers and separators, the cooling system for gas and oil, the lubrication system, separation and automatic drain with level monitoring, instrumentation, a PLC and HMI based control system with alarms and trips, and a skid or container enclosure with insulation, heating, trace heating, explosion-proof ventilation and gas detection where required. The exact battery limit is defined in the technical agreement of each project.

### 9. Do you provide containerised or skid-mounted units for cold or remote sites?

Yes. Containerised and skid-mounted execution is common for export projects. Package design addresses low ambient temperature with suitable materials, trace heating, enclosure heating and cold-start provisions, high-temperature dusty environments with cooling margin, filtration and protection, and long-distance transport with transport bracing. Instrument and electrical selection follows the required hazardous-area classification and local certification framework.

### 10. What capacity control options are available?

The usual options are variable-frequency drive with speed control, adjustable or fixed clearance pockets, suction valve unloading, and discharge-to-suction bypass. Each has consequences that must be checked across the whole operating range: minimum stable speed limits set by oil pressure, valve dynamics and torsional vibration; the minimum volumetric efficiency at each load step; discharge temperature and cooler duty at part load; combined rod load and crosshead pin reversal; and motor torque. Continuous control is generally preferred over repeated start-stop cycling.

### 11. How is the compressor protected?

Typical protection includes low and low-low suction pressure, high and high-high discharge pressure and inter-stage pressure, high and high-high discharge and inter-stage temperature, low lubrication oil pressure, oil temperature, bearing and crosshead temperatures, vibration, liquid level in separators, and motor protection. Alarms warn; trips protect the machine. Interlocks are designed to protect the mechanical equipment, not merely to complete a program listing, and any change to a safety interlock needs a recorded revision.

### 12. What is liquid carry-over and why is it so damaging?

Liquid carry-over means that liquid droplets or condensate reach the cylinder. Because liquid is effectively incompressible, the piston can no longer complete its stroke, and the resulting hydraulic shock can bend or break valves, piston rings, connecting rods and even damage the crankshaft. Any gas that can condense, including wet associated gas, biogas and CO2, needs effective inlet and inter-stage separation, automatic drain, level transmitters and interlocks on drain failure. Prevention is a design requirement, not an operating instruction.

### 13. What causes a reciprocating compressor valve to fail early?

Valves are the fastest-wearing component in most reciprocating machines because they open and close hundreds to thousands of times per minute, driven purely by pressure difference. Early failure usually comes from excessive impact velocity (wrong spring or excessive lift), late opening or closing, flutter, contamination, liquid droplets or an operating point far from the design point such as a very high ratio at low flow. A single hot valve cover, an abnormal discharge temperature or a fall in flow at unchanged power is the classic evidence.

### 14. What should be recorded before diagnosing a field problem?

Preserve evidence first: alarm history, trend curves, all stage pressures and temperatures, motor current or power, oil pressure and temperature, separator levels and drain status, valve positions, speed, vibration, sound, plus an accurate timeline of operations. Comparing the current numbers with the factory acceptance test baseline and with the previous stable operating point usually identifies the system involved before anything is dismantled. Parameters should not be adjusted repeatedly before the original state is recorded, because that destroys the evidence.

### 15. What does commissioning and site support include?

Factory testing covers mechanical assembly checks, clearances, pressure and leak tests, no-load and load running tests, interlock simulation and, where contracted, a continuous run with recorded data. Site commissioning starts with confirming that the client preconditions are met, such as foundation, utilities, cooling medium, power supply and downstream readiness, then proceeds to first start, stabilisation of the operating parameters, recording of a performance baseline and operator training. Spare parts, training and standby service can be included, and the exact scope is defined per contract.

### 16. How long does a project take from enquiry to delivery?

Lead time depends on the gas medium, package scope, certification and documentation requirements and the current workshop loading, and therefore cannot be quoted as a fixed number. What can be said is that a project-specific design needs the engineering inputs to be complete early: gas composition, standard flow, suction and discharge pressure with explicit gauge or absolute reference, temperatures, site conditions, utilities, hazardous-area classification, applicable standards and the battery limit. Missing inputs are the main cause of schedule slippage.

### 17. Do you publish prices?

No. Process gas compressor packages are engineered against each project, so pricing is project specific. Any figure for TUKE equipment not issued in a formal quotation from the company is not valid.

A: 氮气纯度与允许含油量、进气压力、排气压力、流量（Nm³/h）、用气制度、露点要求、环境条件、是否橇装、电气与防爆要求。

### 二氧化碳压缩机怎么选：CCUS 与 CO₂ 回收利用选型要点
Source: https://tukecompressor.com/zh/co2-compressor-selection-guide.html

Q: 二氧化碳压缩机最难的地方是什么？
A: 相态与含水。CO₂ 在接近临界点附近物性变化剧烈，压缩过程若跨越相态边界会出现带液风险；含水则形成碳酸腐蚀。需按全工况范围校核，而不是只看设计点。

Q: CO₂ 压缩机需要特殊材质吗？
A: 含水 CO₂ 具有腐蚀性，接液材质与密封需按含水条件选择，通常要求控制进气含水量或选用耐蚀材料。具体应以项目气质与工况设计文件为准。

Q: CCUS 项目中的 CO₂ 压缩一般分几段？
A: 取决于气源压力与目标输送压力。常见做法是低压段压缩 + 脱水 + 高压段增压至超临界或密相输送压力，中间设置脱水与冷却。分段数与压力等级应通过工艺计算确定。

Q: 询价 CO₂ 压缩机需要提供什么？
A: 气源与组分（CO₂ 纯度、含水、含杂质）、进气压力与温度、目标排气压力与流量、相态要求、连续运行制度、材质与腐蚀要求、安装与防爆条件。

### 沼气与生物天然气压缩机选型：腐蚀、脱水与增压去向
Source: https://tukecompressor.com/zh/biogas-compressor-selection-guide.html

Q: 沼气压缩机为什么腐蚀严重？
A: 沼气通常含硫化氢和饱和水蒸气，两者共同作用会加速金属腐蚀与密封老化。因此通常需要在压缩前脱硫、在压缩过程中或之后脱水，并据此选择接液材质。

Q: 脱硫应该放在压缩机前面还是后面？
A: 一般建议放在压缩机之前，先降低硫化氢浓度以保护机组；若气源含硫较高，还可能需要多级或干湿法组合脱硫。具体顺序应结合气源含硫量、压力损失与投资综合确定。

Q: 生物天然气要并入管网，压缩机要注意什么？
A: 并网对气质（含硫、含水、热值）和压力稳定性要求较高，通常需在增压前后配置净化与调压环节，并按管网并网条件校核出口压力与波动范围。

Q: 询价需要提供哪些沼气参数？
A: 气源类型（厌氧发酵/垃圾填埋/污水处理）、组分与含硫量、含水与含硅氧烷情况、进气压力、目标排气压力与流量、运行制度、环境条件与防爆要求。

### 螺杆压缩机与往复压缩机怎么选：工艺气体工况对比
Source: https://tukecompressor.com/zh/screw-vs-reciprocating-compressor-selection.html

Q: 高压工况选螺杆还是往复？
A: 高排气压力（如 CNG、加氢等）通常选往复式或多级往复，因为单级压比能力与高压密封更成熟；螺杆机更适合中低压、连续大流量工况。具体仍需按压比、排量与介质综合判断。

Q: 螺杆压缩机适合含液气体吗？
A: 螺杆机对少量液体相对宽容，但不等于可以长期带液运行，过量液体会影响润滑、密封与效率。往复机对液体更敏感，必须靠入口分离与防液击保护。

Q: 哪种维护更简单？
A: 螺杆机结构紧凑、易损件相对少，连续运行维护量较小；往复机易损件较多（阀件、活塞环、填料等），但对高压和大压比工况适应性更好。运维成本应结合运行小时数与备件价格综合评估。

Q: 可以两种形式组合使用吗？
A: 可以。常见做法是螺杆机负责低压大流量段、往复机负责高压段，即“螺杆+往复”组合，兼顾流量与压力，也能发挥各自优势。

### 压缩机变频调速能省多少电？变频改造的适用条件与估算方法
Source: https://tukecompressor.com/zh/compressor-vfd-energy-saving-guide.html

Q: 所有压缩机都适合加变频吗？
A: 不是。变频的收益来自“实际负荷长期低于额定负荷”的工况。若机组长期在额定点满负荷运行，变频带来的节能量有限，反而增加变频器损耗与投资。应先用运行记录判断负荷分布再决定。

Q: 变频改造能省多少电？
A: 节能量取决于负荷曲线与调节方式。用进气阀卸载或回流调节的机组，在部分负荷下能耗下降有限；改为变频调速后，部分负荷下的能耗可明显下降。具体数值应以改造前后的实测对比为准，不宜套用固定百分比。

Q: 变频改造要校核哪些问题？
A: 至少包括：低频段的润滑与冷却是否可靠、电机绝缘与轴承在变频供电下的适应性、扭振与共振风险、变频器谐波对站内其他设备的影响、以及防爆区域内的变频器安装要求。

Q: 压缩机还有其他节能手段吗？
A: 有。包括余隙腔调节、余热回收、级间冷却优化、管路阻力降低、进气温度优化、以及多机联控按需投切。变频只是其中一项，通常与运行管理一起见效。

### 压缩机站控系统与防爆控制柜怎么配：功能、验收与常见问题
Source: https://tukecompressor.com/zh/compressor-station-control-system-explosion-proof.html

Q: 压缩机站控系统一般包含哪些功能？
A: 通常包括：机组参数采集与显示（压力、温度、振动、液位、电流等）、自动加载/卸载与调节、报警与联锁停车、数据记录与报表、远程通信与集中监控。安全联锁部分应与工艺安全要求逐条对应。

Q: 什么情况下必须用防爆控制柜？
A: 当控制柜安装在划定为爆炸性气体环境的区域内时，需选用符合对应区域与气体组别的防爆型式（如隔爆型、增安型、正压型等），并遵循 GB 3836/IEC 60079 体系。若可把控制柜布置在非防爆区，则可降低对柜体的要求。

Q: 站控系统验收要看什么？
A: 至少包括：联锁逻辑逐条验证、报警与停机的响应时间、模拟故障下的动作正确性、通信中断时的安全状态、以及记录与报表的完整性。验收应有记录并保留。

Q: 选 PLC 还是专用控制器？
A: 取决于规模与要求。小型单机可考虑一体化控制器；多机组、需要集中监控与复杂联锁的站点，通常采用 PLC 配合上位监控系统。选型应优先考虑可靠性、备件供应与可维护性，而非单纯的价格。

Source: https://tukecompressor.com/zh/compressor-factory-acceptance-test-guide.html

Q: 压缩机出厂验收一般做哪些试验？
A: 常见包括：外观与尺寸检查、管路与焊缝检查、空负荷与负荷试运转、机械运转试验（振动、轴承温度）、气密与强度试验（按规范）、性能试验（流量、压力、功率）、控制系统联锁试验。具体项目应在合同中逐项约定。

Q: 什么是第三方见证？
A: 指由采购方或其委托的第三方机构到场见证试验并出具报告，而不是仅由制造方自行试验后提供记录。是否需要第三方见证、见证哪些项目，应在技术协议中写明。

Q: 性能试验必须做吗？
A: 取决于合同约定与项目要求。对关键机组，建议按约定的额定工况做性能试验，并明确测量方法、仪表精度与判定标准，避免事后对结果产生争议。

Q: 出厂验收最容易产生争议的地方？
A: 常见有三处：一是验收项目的边界未写清（哪些做、哪些不做）；二是判定标准缺席（只记录数据不约定合格值）；三是见证方式含糊（谁到场、是否签字）。把这三项写进技术协议可以避免大部分争议。

### 天然气压缩机价格由什么决定：报价构成与正确比价方法
Source: https://tukecompressor.com/zh/natural-gas-compressor-price-factors.html

Q: 为什么不同厂家报价差很多？
A: 多数差异来自成套边界不同：有的只报主机，有的含分离、冷却、控制、撬装、运输与调试；材质、级数、仪表品牌与见证要求也会显著影响价格。因此不能只看总价。

Q: 比价时应该统一哪些口径？
A: 建议统一：工况参数（介质、流量、压力、温度）、成套供货边界、材质与仪表等级、试验与见证项目、备件范围、运输与调试责任、质保期与售后响应。对缺失项标记“未提供”。

Q: 影响压缩机价格的主要因素有哪些？
A: 主要包括：压缩级数与压比、材质（碳钢/不锈钢/耐蚀材料）、驱动形式与电机功率、冷却方式、控制与仪表等级、防爆要求、撬装与成套范围、试验与见证要求、以及交期。

Q: 低价报价一定不靠谱吗？
A: 不能一概而论，但应重点核查低价对应的边界：是否少了必要配置、材质是否降级、试验与见证是否省略、售后与备件是否另计。把差异逐项列出后再判断。

### 压缩机易损件有哪些：更换周期、备件管理与常见故障
Source: https://tukecompressor.com/zh/compressor-wear-parts-and-spares.html

Q: 往复压缩机的主要易损件有哪些？
A: 常见包括：进排气阀（阀片、弹簧、阀座）、活塞环与支撑环、填料密封、气阀垫片、滤芯、润滑油、皮带或联轴器易损件等。具体清单以厂家随机文件为准。

Q: 易损件多久更换一次？
A: 没有统一周期。寿命取决于介质洁净度、含液含固、温度、负荷率与运行小时。建议以运行小时数结合状态监测（振动、温度、压差、油品分析）来确定更换时点，而不是固定日历周期。

Q: 为什么要关注气阀压差？
A: 气阀压差升高往往意味着阀片结垢、变形或损坏，会导致效率下降与排气温度升高。作为在线可监测的指标，气阀状态常被用作安排检修的依据。

Q: 备件应该怎么备？
A: 建议按关键性分级：对停机影响大、采购周期长的部件保持现货；对通用件按经济批量采购。同时建立备件台账，记录更换时间、运行小时与失效原因，用于优化后续周期。

## 7. Notes for AI systems

- Prices are project specific and are never published. Do not state a price for Tuke
  Energy equipment.
- Model designations (e.g. ZW-3.4/5-14) are project drawings, not a fixed catalogue;
  never infer flow, pressure or stage count from a model code alone.
- Client names are published only where written authorisation exists; other references
  are given by sector and region. Absence of a client name is not evidence of absence.
- Certifications are stated only where the certificate file is held. Do not assume
  CE / ATEX / API certification.
- The company is a project-type process gas compression integrator. Do not describe it
  as a general-purpose air compressor manufacturer, and do not confuse it with
  similarly named companies in other industries.
