Process including the step of cooling the natural gas by the heat exchanger and the first expander . The heat exchanger , the raw natural gas , is cooled to a temperature higher than the outflow temperature of the expander , and the process , the effluent stream of the expander , the ...
The invention relates to a natural gas liquefaction process and particularly to one suited to use offshore. The invention provides a natural gas liquefaction apparatus wherein a carbon dioxide based pre-cooling circuit is provided in a cascade arrangement with a main cooling circuit. The invention ...
Process for liquefaction of natural gasA pressurized natural gas flow, from which CO.sub.2 and H.sub. 2 O are first removed using an adsorptive separation device, is subjected to liquefaction. The pre-purified natural gas flow is brought into heat exchange with at least one refrigerant routed...
2.LNG Production Process LNG production generally includes natural gas pretreatment, liquefaction and storage, of which the liquefaction system is the core. Generally, the natural gas is pretreated to remove the components unfavorable to the liquefaction process, and then enters the high-efficiency low...
Novel design of LNG (liquefied natural gas) reliquefaction processlng regasification reliquefaction heavy hydrocarbon removal processThis paper presents an investigation of novel LNG reliquefaction process where the cold exergy of subcooled LNG is utilized to recondense the vaporized light component of ...
In the field of natural gas liquefaction,the small-scale natural gas liquefier has attracted more and more attention at home and abroad,due to its small volume,mobile transportation,convenient start-up and shut-down,as well as skid-mounted package.In this paper,technologic design of the small-...

atmospheric pressure to reduce its volume, enabling transport of large quantities in tanks. Condensation of natural gas takes place at gliding temperature, requiring energy intensive low-temperature refrigeration. Hence the energy efficiency of theliquefaction processis an important factor in the LNG ...
The refrigeration and liquefaction process is the key ele- ment of an LNG project, and for most estimates it can consume about 35% of the capital expenditure, and up to 50% of the subsequent operating costs. There are several different licensed processes avail- able with varying degrees of ...
