SYSTEM AND METHOD FOR REMOVING ACID GAS IN SHIP OR MARINE STRUCTURE USING SOLID ADSORBENT-FILLED ADSORPTION COLUMN

摘要

The present invention relates to a system and a method for removing acid gas in a ship or a marine structure using a solid adsorbent-filled adsorption column and, more particularly, to a system for removing acid gas in a ship or a marine structure using a solid adsorbent-filled adsorption column, which is connected to a supply line of natural gas containing acid gas provided in a floating marine structure, includes an acid gas adsorption column adsorbing and removing the acid gas contained in the natural gas supplied from the supply line as filled with a solid adsorbent, wherein a downstream discharged from the column is branched, a main stream is supplied to a next process, and a substream is heated and supplied to the column to separate the acid gas adsorbed onto the solid adsorbent. According to the present invention, acid gas is removed by using a column filled with solid adsorbent not with liquid amine-based absorbent, therefore only a small space is required in the hull of a structure and the top side as the number of a storage tank, a pump and the like is small, and capital expenditures (CAPEX) of total floating marine structures can be reduced. The effect of hull motion of a structure in a marine environment can be significantly reduced due to using an adsorbent packed bed column.;COPYRIGHT KIPO 2015
