TH78331A - Liquefaction of natural gas - Google Patents

Abstract

The DC60 has disclosed a method for liquefying natural gas, which is combined with current generation. Liquids containing hydrocarbons that are heavier than methane are primarily used in the gas flow process to be obtained. Liquefaction Will be partially cooled And is divided into the first and second currents, the first currents are further cooled for all significant condensation of this current, which is amplified until there is a neutral pressure and then Get shipped to the distillation column at the center of the first column. The second current has been inflated until there is a pressure. The middle value is also available and is then shipped to the distillation column at the center input location. Second bottom column The distillation current is drawn from the column below the second current feed point and is cooled to at least part of this condensing current forming the reflux current. At least part of the reflux current has been forced to The distillation column is the top feed stream. Bottom products from this distillation column should contribute Primarily, any hydrocarbon is heavier than methane. Which if this is not done will reduce the purity of the gas Liquid nature The residual gas stream from the distillation column is compressed to a higher central pressure, cooled under pressure for condensation, and then expanded to provide a Low pressure for the formation of a liquid natural gas stream Has disclosed a process for the liquefaction of natural gas, which, together with the production of current Liquids containing hydrocarbons that are heavier than methane are primarily used in the gas flow process to be obtained.
