Oxygen & Utility Plant

Overview

An oxygen and hydrogen plant compresses oxygen, nitrogen and argon in the air, and extracts the respective gases through the processes of purification, cooling and rectification. The extracted gases are used for production processes.

A gas holder is a facility that maintains the balance between the generation and consumption of by-product gases from steel making processes, and ensures the uniform composition of gases and the constant pressure of gases. We have successfully performed the design, procurement, construction and commissioning of many oxygen/hydrogen plants and gas holders based on our proven technology and experience.
