Pressure Swing Adsorption Technology and Equipment for Air Separation to Produce O2 and N2

Compared with cryogenic distillation, membrane permeation, and chemical absorption, pressure swing adsorption (PSA) for air separation to produce nitrogen and oxygen-enriched air offers advantages such as lower capital investment, reduced energy consumption, smaller footprint, enhanced safety and convenience, and a high degree of automation.

Pressure Swing Adsorption Technology and Equipment for Removing Carbon Dioxide from Synthesis Ammonia Shift Gas

In the field of ammonia synthesis, the shift gas produced in the shift section is typically processed using either dry or wet methods. The wet methods can be further classified into chemical absorption, physical absorption, and combined physical–chemical absorption. The dry method refers to pressure swing adsorption.

Pressure Swing Adsorption Technology and Equipment for Hydrogen Purification from Hydrogen-Containing Gases such as Catalytic Dry Gas and Off-Gas

High-purity hydrogen is extracted using pressure swing adsorption, which is suitable for hydrogen-containing feedstocks such as refinery dry gas, ammonia synthesis purge gas, ammonia decomposition gas, and methanol off-gas.

Prisen membrane recovery and high-purity H2 extraction

Our company utilizes high-performance Prisma membranes imported from the United States, combined with a self-designed and optimized process flow, to recover hydrogen from purge gas generated during ammonia synthesis, venting from ammonia storage tanks, and methanol tail gas in conventional processes. The recovered hydrogen is then reintroduced into the production system, achieving increased output and reduced consumption. Both the purity and recovery rate of the hydrogen exceed 92%, while the resulting by-products—ammonia or methanol—meet commercial-grade specifications.
