Natural gas liquefaction process in combination with a synthesis gas production process, where the steam derived from the synthesis gas production process is used as a heating source for the implementation of the pre-treatment step for eliminating the impurities liable to freeze during the natural gas liquefaction process.

Synthesis gas production process for the implementation of a natural gas liquefaction

A process for the purification of a gas rich in hydrocarbons and comprising at least 10 ppm by volume of hydrocarbons having at least six carbon atoms nitrogen.

Method for purifying a gas rich in hydrocarbons

A process for producing liquefied natural gas and liquid carbon dioxide from a natural gas feed gas comprising at least the following steps: Separation of a natural gas feed gas into a CO-enriched gas stream and a natural gas stream; Cooling of said natural gas in a heat exchanger; Purification of the in step 1 from compounds containing at least six carbon atoms; At least partial condensation of said gas stream resulting from step 3 to form a two-phase stream; Separation of said two-phase stream resulting from step 4 to form a gas stream and a liquid stream; Condensation of the gas stream resulting from step 5 to form a liquefied gas containing less than 5 ppm by volume of compounds containing at least six carbon atoms; Liquefaction of the CO-enriched gas stream resulting from step 1 with a portion of the liquid stream resulting from step 5.
