Equipment & Engineering

Hangyang is the manufacturer of the first ASU in China. The first sets of products of various series of air separation plants from small to large in China are all developed by Hangyang. Up to now, Hangyang has provided more than 4,000 sets of air separation equipment for various industries in China; among them, 88 sets of super-large air separation units with a grade of 60,000 and above, with a domestic market share of more than 50%, and the world's largest output and sales. The air separation plant of Hangyang has a maximum grade of 120,000 m³/h. It is a 100,000-grade air separation plant developed for the 4 million tons/year indirect coal liquefaction project of Shenhua Ningxia Coal. The overall technology has reached the international leading level.

Specialty Gas

Hangyang is committed to the localization of special gases, and can develop all kinds of special gases according to customer needs, providing customers with one-stop gas solutions and services. At present, it is mainly engaged in electronic special gases, including high-purity and ultra-high-purity krypton xenon neon rare gases, laser gases, etching gases (fluorine-containing electronic mixtures), etc.; construction and operation of electronic bulk gas stations, including oxygen, nitrogen, argon, hydrogen , helium, CDA; aerospace-grade xenon, aerospace-grade krypton; high-end medical gas, including medical oxygen, medical detection mixture, excimer laser gas, etc.; food preservation gas, including food-grade carbon dioxide, food additive nitrogen; energy gas liquid Hydrogen; stable isotope gas oxygen, carbon, nitrogen, etc.; electric light source gas mixture, etc.; standard gas.

New Energy

Hangyang seized the opportunity of new energy development and established a hydrogen industry development center to focus on the research and development of hydrogen energy technology. It has a relatively mature hydrogen purification technology reserve, and has authorized 2 hydrogen-related invention patents. The company has the technical design capabilities of the whole process of hydrogen liquefaction and the production and manufacturing capabilities of key equipment, and has completed the development and design of process packages for 0.5-10 tons/day hydrogen liquefaction units. Hangyang has advanced the helium refrigeration cycle hydrogen liquefaction technology, and realized the technical reserves of 1200L/h helium cycle hydrogen liquefaction: the purity of liquid hydrogen is >99.999%, and the content of parahydrogen >95%, which provides valuable technical support for the development of large-scale hydrogen liquefaction equipment.
