T/CI 235-2023 Active

Main technical content: This document specifies the terms and definitions, product specifications, operating conditions, technical requirements, test methods, inspection rules, marking, random documents, packaging, transportation, and storage of high-purity oxygen generators using pressure swing adsorption (PSA) technology. This document applies to equipment (hereinafter referred to as "high-purity oxygen generators") that uses oxygen molecular sieves to separate nitrogen from air to produce oxygen at room temperature and purifies and separates argon using oxygen purification devices, with an oxygen content of not less than 99% and an oxygen production capacity of not more than 300 Nm3/h. Note 1: The oxygen production capacity in this document refers to the gas volume at standard conditions, i.e., 0°C and 0.101325 MPa (absolute pressure), and is expressed in cubic meters (m3). Note 2: Unless otherwise specified, all pressure values are gauge pressures.
