The present invention relates to a gas treatment system with greatly improved energy efficiency and an offshore structure including the same. The gas treatment system is arranged on an offshore structure to receive gas from a gas well to treat gas. The system comprises: a moisture removal unit having an adsorption column to adsorb moisture included in gas produced by the gas well; and a liquefying unit to liquefy gas from which moisture is removed and separate gas and liquid. The moisture removal unit includes: a regeneration gas supply unit to supply high-temperature regeneration gas for evaporating and separating moisture adsorbed onto the adsorption column to the adsorption column; a regeneration gas cooling unit to cool regeneration gas discharged from the adsorption column with steam to condense steam; and a moisture separation unit to separate condensed moisture from regeneration gas. The regeneration gas cooling unit exchanges heat between at least a portion of liquefied gas separated by the liquefying unit and regeneration gas to cool regeneration gas.

    본 발명은 가스 처리 시스템 및 이를 포함하는 해양 구조물에 관한 것으로서, 해양 구조물에 마련되어 가스정으로부터 가스를 공급받아 처리하는 시스템으로서, 상기 가스정에서 생산되는 가스에 포함된 수분을 흡착하는 흡착칼럼을 갖는 수분 제거부; 및 수분이 제거된 가스를 액화하고 기액분리하는 액화부를 포함하며, 상기 수분 제거부는, 상기 흡착칼럼에 흡착된 수분을 기화시켜 분리하기 위한 고온의 재생가스를 상기 흡착칼럼에 공급하는 재생가스 공급부; 스팀과 함께 상기 흡착칼럼에서 배출된 재생가스를 냉각하여 스팀을 응축시키는 재생가스 냉각부; 및 응축된 수분을 재생가스에서 분리하는 수분 분리부를 포함하고, 상기 재생가스 냉각부는, 상기 액화부에서 기액분리된 액화가스 중 적어도 일부와 재생가스를 열교환하여 재생가스를 냉각하는 것을 특징으로 한다.
