T/CI 234-2023 Active

Main technical content: This document specifies the terms and definitions, product specifications and parameters, technical requirements, test methods, inspection rules, marking, random documents, packaging, transportation, and storage of high-purity nitrogen generators using pressure swing adsorption (PSA) technology. This document applies to equipment (hereinafter referred to as "high-purity nitrogen generators") that separates nitrogen from air using molecular sieve pressure swing adsorption (PSA) at normal temperature, and purifies it through carbon-loaded purification devices, with a nitrogen content of not less than 99.999% and a nitrogen production capacity of not more than 800 Nm3/h. Note 1: The nitrogen production capacity in this document refers to the gas volume under standard conditions, i.e., 0°C and 0.101325 MPa (absolute pressure), expressed in cubic meters (m3). Note 2: Unless otherwise specified, all pressure values are gauge pressures.
