Title:
水素を液化する方法及び装置
Document Type and Number:
Japanese Patent JP5739388
Kind Code:
B2
Abstract:
Hydrogen is liquefied by a process comprising precooling hydrogen feed gas (16) by indirect heat exchange (12) against pressurised liquefied natural gas ("LNG") (14) to produce pre-cooled hydrogen feed gas (20) and pressurised natural gas (22), further cooling at least a portion of said pre-cooled hydrogen feed gas by indirect heat exchange (24,46) against at least one refrigerant (32,40,58) to produce condensable hydrogen gas (48) and expanding (50) at least a portion of said condensable hydrogen gas to produce at least partially condensed hydrogen (52). One advantage of such a process is that the power consumed during liquefaction is significantly less than that consumed in existing hydrogen liquefaction processes which pre-cool hydrogen feed gas by indirect heat exchange against other refrigerants, e.g. liquid nitrogen.
