Scope

Scope: This document specifies the terms and definitions, classification and naming, technical requirements, testing and inspection, marking, product random documents, and packaging for hydrogen production systems using various hydrogen-containing gases as raw materials and employing the medium-temperature pressure swing adsorption (ETPSA) method to purify hydrogen. This document is applicable to industrial and commercial fixed-type medium-temperature pressure swing adsorption hydrogen purification systems. Main technical content: - Medium-temperature pressure swing adsorption (ETPSA) method: This method utilizes the selective adsorption of different gases by solid adsorbents at temperatures ranging from 120°C to 450°C, as well as the change in the adsorption quantity of gases on the adsorbent with pressure. Under certain pressure, the adsorbed gases are separated by desorption when the partial pressure of the adsorbed gases is reduced. - 3.2 Hydrogen purification system by elevated temperature pressure swing adsorption: A hydrogen production system that purifies hydrogen from hydrogen-containing gases using the medium-temperature pressure swing adsorption method. - 3.3 Fire arrester: A device designed and manufactured based on the principle that when a flame passes through a narrow gap of a heat conductor, the flame is extinguished due to heat loss, used to prevent external flames from entering equipment or pipelines containing flammable and explosive gases, or to prevent flames from spreading within equipment or pipelines. - 3.4 Hydrogen recovery rate: The ratio of the volume of pure hydrogen in the product hydrogen (standard state) to the volume of hydrogen contained in the raw gas (standard state) when hydrogen is produced using the medium-temperature pressure swing adsorption method. - 3.5 Stationary hydrogen purification system by elevated temperature pressure swing adsorption: A stationary hydrogen purification system using medium-temperature pressure swing
