Technical Introduction:
The process flow of LNG liquefaction plant basically includes pretreatment (purification), liquefaction, storage, loading machine and auxiliary system, etc., and the main process flow includes raw gas purification and liquefaction process. According to the customer's gas source conditions, the raw gas is purified, including filtration, deweighting hydrocarbons, deacidification gas, dehydration, mercury removal and other units. There are several options for liquefaction process, such as natural gas throttling, nitrogen expansion, nitrogen methane expansion, natural gas expansion, stepped refrigeration cycle, MRC refrigeration, propane precooling + MRC refrigeration, etc.
Technical Features:
1. Provide complete sets, skids supply, easy installation;
2. Differentiated process design and engineering design according to the composition of raw natural gas;
3. DCS control system is adopted to realize unattended.
