In-depth decarburization process for raw natural gas

The invention provides an in-depth decarburization process for raw natural gas. The in-depth decarburization process comprises the following steps: 1) pressurizing a decarburization absorption tower; 2) continuously injecting a circulation volume of an alcohol-amine solution into the top of the deca...

Zusammenfassung:	The invention provides an in-depth decarburization process for raw natural gas. The in-depth decarburization process comprises the following steps: 1) pressurizing a decarburization absorption tower; 2) continuously injecting a circulation volume of an alcohol-amine solution into the top of the decarburization absorption tower via a centrifugal pump; 3) after stabilization of the temperature and pressure of the decarburization absorption tower, continuously introducing raw natural gas into the bottom of the decarburization absorption tower, and allowing purified natural gas obtained after CO2 is absorbed and decarburized by the alcohol-amine solution to flow out from the top of the decarburization absorption tower; and 4) discharging the alcohol-amine solution having absorbed CO2 to be discharged from the bottom of the decarburization absorption tower, regenerating the alcohol-amine solution and returning the regenerated alcohol-amine solution to the top of the decarburization absorption tower via the centrif
