Methods and Measures for Stabilizing the Heat Value of Mixed Gas

The production state of various units of gas mixing stations at Ma Steel was analyzed. Methods and measures were taken such as manually composing LDG, big pipe and small pipe proportioning, hydrogen desorption gas recovery and natural gas blending and using mathematical model in station proportioning to stabilize the pressure of BFG, COG and LDG and the consumption quantity of users, to satisfy the requirement on the heat value stability of mixed gas under different operation conditions and achieve steady supply of high quality mixed gas to users.
