In 2019, we signed an EPC contract with Jinxi Iron and Steel Co., ltd to supply one set of 60,000Nm³/h air separation plant.

The air separation plant adopts molecular sieve adsorption purification, pressurized turboexpander, full packing rectification, and liquid oxygen self-pressurization process. It is also an inert gases full extraction plant with products of argon, krypton, xenon, neon and helium. The complete set of air separation equipment includes: air filtration system, air compressor unit, air pre-cooling system, molecular sieve purification system, fractionation column system, full rectification hydrogen-free argon production system, neon helium rectification system, krypton xenon rectification system, instrument and electric control system.

This set of air separation was put into use recently, and all indexes have met the design requirements.
