Safety Control for Large Scale Liquefied Hydrogen Production Plant Site

Abstract

Liquefied hydrogen is mainly utilized for propellant of the space rocket in Japan. However its mass consumption is expected as a clean energy, a high purity gas and a extremely low temperature refrigerant. In this report industrial production scheme and safety control for the liquefied hydrogen plant are described from the writer’s experience. Improvement of the safety control will be required more and more on a large quantity of hydrogen handling.
