IPC: F25J3/08
Filed: 1989-09-04
Abstract: PURPOSE:To collect high purity nitrogen by removing CO contained in a stock liquid nitrogen with a low temperature adsorber, particles with a particle filter, and further eliminating H2 in a nitrogen refining tower. CONSTITUTION:Stock liquid nitrogen is introduced into a low temperature adsorber 1 where CO is mostly eliminated due to low temperature adsorption. In a nitrogen condenser 2, the nitrogen exchanges heat with a rising gas of a nitrogen refining tower 6 and gets vaporized and heat up to the ambient temperature by a nitrogen heat exchanger 3 after the gasification. Furthermore, ambient temperature nitrogen gas is boosted to a specified pressure by a nitrogen booster 4 where particles are removed by a particle filter 5. Then, the nitrogen gas is cooled up to near the point of liquefaction by the nitrogen heat exchanger 3 where it comes in contact with a circulating solution from the upper part during a process rising in the nitrogen refining tower 6. During this process, mostly H2, which is a low boiling point component, is refined and separated. The rising gas exchanges heat with the stock liquid nitrogen in the nitrogen condenser 2 where it gets condensed and turned into the circulating solution of the nitrogen refining tower 6 and drops so that it may be deposited a sump in the lower part of the nitrogen refining tower 6. High purity nitrogen can be sampled in this manner.
