NGK, Mitsubishi Heavy Industries to develop hydrogen purification system from ammonia cracking gas

In Japan, NGK and Mitsubishi Heavy Industries (MHI) said they will jointly develop a hydrogen purification system that uses membrane separation to purify from hydrogen-nitrogen mixture gas after ammonia cracking. The companies said they expect the technology to contribute to the establishment of a hydrogen and ammonia supply chain enabling high-volume transport. The partners also noted that this joint project aims to build an optimal system for purifying hydrogen using membrane separation from the mixed gas of hydrogen and nitrogen generated during from the ammonia cracking gas. MHI will contribute its expertise delivering ammonia plants and other chemical plants, and its technologies for handling ammonia and hydrogen. NGK will contribute its deep knowledge of sub nano ceramic membrane technology and unique film deposition technology developed in the fields of chemical processes and water purification.
