METHOD OF SEPARATION OF PRESSURIZED INITIAL MULTICOMPONENT MATERIAL FLOW BY DISTILLATION |
摘要 |
FIELD: processes or apparatus for separating of gaseous mixtures. SUBSTANCE: method for extracting of high-volatile component such as nitrogen from initial material rich in methane with the purpose of obtaining of product free from high-volatile component includes expansion of initial flow; introducing of expanded initial flow into phase-separation device in which liquid flow and vapor flow rich in volatile component are formed; pressurizing of liquid flow enriched in methane having low content of volatile component; heating of pressurized liquid flow for obtaining of pressurized liquefied product pressure of which provides product temperature less or equal to boiling temperature thereof, namely more than - 112 C (- 170 F). EFFECT: enhanced extraction of nitrogen from natural gas flow simultaneously with obtaining of pressurized liquefied natural gas. 12 cl, 2 dwg, 2 tbl
