요약

A natural-gas purification apparatus includes: a compressor that adjusts the pressure of natural gas from the ground; a cooling unit that liquefies and separates a part of natural-gas liquid by cooling the natural gas after the pressure adjustment by the compressor; a heating unit that heats the natural gas after the separation of the part; a carbon-dioxide separation unit that separates carbon dioxide from the natural gas heated by the heating unit; and an arithmetic control device that adjusts and controls at least one of the compressor, the cooling unit, and the heating unit to a value which has been set in advance according to the composition of the natural gas, such that the cooling unit will liquefy and separate the part of the natural-gas liquid in the natural gas and the carbon-dioxide separator maintains the remaining part of the natural-gas liquid in the natural gas in gaseous form.

대표청구항

1. A natural-gas purification apparatus for purifying natural gas from ground by separating carbon dioxide from the natural gas, comprising: a pressure adjuster that adjusts a pressure of the natural gas from the ground;a natural-gas-liquid separator that liquefies and separates a part of natural-gas liquid by cooling the natural gas after the pressure adjustment by the pressure adjuster;a heater that heats the natural gas after the separation of the part of the natural-gas liquid by the natural-gas-liquid separator;a carbon-dioxide separator that separates carbon dioxide from the natural gas heated by the heater through a carbon-dioxide separation membrane; anda controller that adjusts and controls at least one of a pressure of the natural gas to be achieved by the pressure adjuster, a temperature to which the natural gas is to be cooled by the natural-gas-liquid separator, and a temperature to which the natural gas is to be heated by the heater to a value which has been set in advance according to composition of the natural gas from the ground, such that the natural-gas-liquid separator liquefies and separates the part of the natural-gas liquid in the natural gas and the carbon-dioxide separator maintains a remaining part of the natural-gas liquid in the natural gas in gaseous form.
