Description:
Process technical scheme
The selection principle of the process plan is mature and reliable, energy saving, reasonable investment and convenient operation and maintenance.
The process scheme is selected to start the rapid cold flow of high and low temperature turbine expansion mechanism. The configured equipment can start quickly and run stably; The unit capacity of the device is sufficient to reduce start-up time.
Technology comparison and selection
The process of natural gas liquefaction basically includes feed gas pretreatment (purification), liquefaction, refrigerant circulation compression, product storage, loading and auxiliary system, etc. The main process includes feed gas purification and purification gas liquefaction process.
Selection of natural gas purification process
As a raw gas, natural gas must be thoroughly purified before liquefaction. In other words, acid gas, water and impurities such as H2S, CO2, H2O, Hg and aromatic hydrocarbons in raw gas are removed to prevent them from freezing at low temperatures and clog and corrode equipment and pipelines.
