NOVELTY - Liquefied natural gas and methanol are simultaneously produced by pre-treating coke-oven gas to remove benzene, naphthalene, tar and hydrogen cyanide; depressurizing pre-treated coke-oven gas; depressurizing obtained desorption methane-enriched gas; desulfurizing the mixed gas of carbon dioxide and hydrogen sulfide and carbon monoxide-enriched gas, removing water from methane-enriched gas; and reacting un-absorbed hydrogen, carbon monoxide-enriched gas in the presence of methanol synthetic catalyst to generate methanol.    USE - Method of producing a simultaneous liquefied natural gas and methanol (claimed).    ADVANTAGE - The method has reduced energy consumption during purification and separation of coke-oven gas, saves energy, has reduced waste discharge, and recycles waste thus reducing pollution.    DETAILED DESCRIPTION - Liquefied natural gas and methanol are simultaneously produced by:    (A) pre-treating coke-oven gas at 25-50 degrees C and pressure of 40-600 (preferably not greater than 90) kPa to remove benzene, naphthalene, tar and hydrogen cyanide;    (B) depressurizing pre-treated coke-oven gas at 35-50 degrees C and pressure of 500-3000 kPa to separate hydrogen gas and desorption methane-enriched gas;    (C) depressurizing obtained desorption methane-enriched gas at 35-50 degrees C and pressure of 600-3000 kPa, and subjecting to deacidification reaction to separate mixed gas of carbon dioxide, hydrogen sulfide and methane-enriched gas;    (D) desulfurizing the mixed gas of carbon dioxide and hydrogen sulfide to obtain carbon monoxide-enriched gas, removing water from methane-enriched gas, and liquefying water-free methane-enriched gas to obtain liquefied natural gas;    (E) purifying carbon dioxide and carbon monoxide-enriched gas; and    (F) reacting un-absorbed hydrogen and carbon monoxide-enriched gas in the presence of methanol synthetic catalyst to generate methanol.    DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method of producing a simultaneous liquefied natural gas and methanol. Drawing includes non-English language text.
