Low-Cost PSA Hydrogen Production Unit

General

In the production process of coking, iron making and steelmaking, iron and steel enterprises produce a large number of gas by-products, among which H2 is high in content, which is a commonly used gas fuel and also an important secondary energy source.

Making full use of the by-product gas of iron and steel enterprises can not only save a lot of fuel, but also extract clean fuel from it, eliminate a large amount of gas discharge, and greatly improve and protect the environment. The product hydrogen with a purity of 99.9-99.999% can be obtained by the mature pressure swing adsorption technology.

Features

• Large scale and high purification
• The product has a high hydrogen purity
• Leading technology

Process Description

Pressure swing adsorption (PSA) for hydrogen extraction is to selectively adsorb the non-hydrogen components of the hydrogen-rich mixture under pressure, so as to achieve the purpose of separation of hydrogen from other gas components. Meanwhile, the adsorbent releases the adsorbed impurity gas under pressure release so that the adsorbent can regain its adsorption capacity.

Founded in 2000, Ally Hi-Tech is an engineering company dedicated to providing engineering service of industrial gas, especially hydrogen.

From design, construction to on-site guidance, after-sale maintenance, Ally has professional teams and provide our clients with customized service. Ally Hi-Tech has been focusing on the innovation of related technology and obtained 38 Chinese patents, 1 European patent, 1 American patent.

Owing to the advanced core tech, Ally participated in 6 national projects including Hydrogen projects of 2008 Olympics and 2020 Expo, while we also provide hydrogen for all the satellite launch centers in China.

Hydrogen production and hydrogen purification is the main business of Ally Hi-Tech.

We participated in the draft of the standards of hydrogen generation by methanol-reforming. As a member of the Chinese hydrogen standard committee, Ally Hi-Tech also took part in the editing of 6 Chinese standards and 1 international standard related to hydrogen.

By now, Ally Hi-Tech has delivered more than 500 units all over the world and built up cooperative relationships with a lot of clients, such as Air Liquide, Linde, Praxair, BP, Iwantani Group, etc.
