PROBLEM TO BE SOLVED: To provide a container in a gas treatment facility for treating natural gas containing hydrogen sulfide, the weight of which is reduced in order to solve a problem such as an increase in the weight due to a tendency of an increase in a size thereof.SOLUTION: A gas treatment device includes a container used in a wet hydrogen sulfide environment in order to treat gas containing hydrogen sulfide such as natural gas, petroleum associated gas and petroleum refining gas. High tensile steel, the yield point of which is ≥300 N/mm, is used as a steel plate for the container. In addition, austenitic stainless steel is lined or overlaid and welded on an inner surface of the steel plate of high tensile steel which constitutes the container. This prevents an inner surface of the container from being corroded by hydrogen sulfide, and prevents atomic hydrogen generation due to the corrosion, thereby preventing hydrogen induced cracking. Furthermore, increased thinning of thickness of the container is promoted using high tensile steel, thereby providing weight reduction of the container. |
