用于反应性气体服务的气体分离膜模块
摘要：
气体分离膜模块包括在较高压力气体与较低压力气体之间的密封件。该密封件包括在多个密封表面之间的可压缩密封构件。这些密封表面中的至少一个具有耐腐蚀包层，该耐腐蚀包层被设置在低合金钢之上或者高合金钢之上。该包层减小了由于低合金钢或高合金钢暴露于酸性气体或者暴露于包含有溶解的酸性气体的冷凝水分而被腐蚀、从而使密封件失效的可能性，同时不要求该膜模块暴露于酸性气体的所有表面都配备有包层。
摘要（英）：

A gas separation membrane module includes a seal between a higher pressure gas and a lower pressure gas. The seal includes a compressible sealing member in between sealing surfaces. At least one of the sealing surfaces has corrosion-resistant cladding provided over either low alloy steel or high alloy steel. The cladding reduce the possibility of a seal failure due to corrosion of low alloy or high alloy steel exposed to acid gases or condensed moisture containing acid gases dissolved therein while at the same not requiring that all surfaces of the membrane module exposed to acid gases be provided with cladding.
