METHOD OF LIQUEFACTION OF NATURAL GAS |
摘要 |
FIELD: technology of liquefaction of natural gas. SUBSTANCE: method includes cleaning of gas from admixtures in two change-over heat exchangers-freezers; one heat exchanger is placed in operation and other heat exchanger is thawed-out and cleaned at this. For thawing-out the heat exchanger-freezer, use is made of warm flow of gas from additional vortex tube working in parallel with vortex tube of cooling loop. Cold flow of gas generated by additional vortex tube is used for final cooling of compressed gas flowing through preliminary heat exchanger-freezer. EFFECT: enhanced efficiency. 2 cl, 1 dwg
