--技术背景--(Technical Background)：

  “模块式天然气液化装置”是采用高度集成、模块化的液化设备对非常规天然气（不便于管输的边远气井天然气、页岩气、煤层气、油田伴生气、盐井伴生气，工业尾气和生物质转化的燃气）进行综合回收利用。采用现场液化方式避免了大量地面设施及管道投资，建立一种液化工厂直接对接终端用户和进入LNG 现货市场的生产运营模式。

“Modular Liquefaction Equipment for Natural Gas” is a highly integrated, modularized liquefaction facility which is designed for unconventional natural gas (such as remote gas well which is inconvenient to transport, shale gas, coal bed gas, oil field associated gas, salt well associated gas, industry exhaust, gas conversion from biomass) complex recycle and utilization. It artfully adopts on-field liquefaction mode which may avoid huge investment on ground facility and pipe line construction, and builds a new production and operation mode which realize direct hand-shake between LNG plant and end consumer or LNG spot market.

--工艺说明--(Process Brief)：

1、原料气净化（Raw Gas Purifying）：

  采用拥有自主知识产权的专利技术净化方法对原料气进行净化处理，使原料气中的酸性气体含量达到工艺要求。净化过程操作简单，能耗低，适用范围广，能用适用于各种常见的天然气气源。 

  By adopting independent intellectual property and patented technology, acidic gases level in raw gas can be purified to the Process requirement. The purifying process is easy to operator, low energy consumption and wide applicable for all kinds of ordinary raw gas sources.

2、天然气液化（Gas Liquefaction）

   采用氮气循环膨胀制冷工艺：利用高压制冷剂通过透平膨胀机绝热膨胀的克劳德循环制冷来实现天然气的液化。气体在膨胀机中膨胀降温的同时，输出功，用于驱动流程中的压缩机。氮气膨胀循环流程简单、紧凑，造价相对较低。起动快，热态起动2～4 小时即可获得满负荷产品，运行灵活，适应性强，易于操作和控制，安全性好，放空不会引起火灾或爆炸危险。  

   It adopts nitrogen cycle expander refrigeration technology: Natural gas gets liquefied in Claude refrigeration cycle due to the adiabatic expansion of high press refrigerant in turbo expander, gas output work during the expansion cooling process, and the expansion work recovered and utilized to drive gas compressor. This process flow is simple, compact, low cost, and quick start. Production load can reach full within 2~4 hours from hot startup. The process described here has flexible, wide applicable, and convenient control performance. It is also has fine safety against fire or blast for air relief.
