1、原料氣凈化（Raw Gas Purifying）：

  采用擁有自主知識(shí)產(chǎn)權(quán)的專利技術(shù)凈化方法對(duì)原料氣進(jìn)行凈化處理，使原料氣中的酸性氣體含量達(dá)到工藝要求。凈化過(guò)程操作簡(jiǎn)單，能耗低，適用范圍廣，能用適用于各種常見(jiàn)的天然氣氣源。 

  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、天然氣液化（Gas Liquefaction）

   采用氮?dú)庋h(huán)膨脹制冷工藝：利用高壓制冷劑通過(guò)透平膨脹機(jī)絕熱膨脹的克勞德循環(huán)制冷來(lái)實(shí)現(xiàn)天然氣的液化。氣體在膨脹機(jī)中膨脹降溫的同時(shí)，輸出功，用于驅(qū)動(dòng)流程中的壓縮機(jī)。氮?dú)馀蛎浹h(huán)流程簡(jiǎn)單、緊湊，造價(jià)相對(duì)較低。起動(dòng)快，熱態(tài)起動(dòng)2～4 小時(shí)即可獲得滿負(fù)荷產(chǎn)品，運(yùn)行靈活，適應(yīng)性強(qiáng)，易于操作和控制，安全性好，放空不會(huì)引起火災(zāi)或爆炸危險(xiǎn)。  

   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.
