Where does oxygen come from?
Thread Content
At present, the normal operation of our company’s methanol plant is constantly hindered by the high oxygen content in the coke oven gas. From a technical perspective, the system from the blower to the gas holder is a pressurized system, so air intake should not cause an increase in the oxygen content in the gas. Similarly, the system from the Roots blower at the gas holder outlet to the advanced desulfurization system is also pressurized, so this issue should not arise there as well. The biggest issue now is whether air will leak in from behind the P-shaped tube flap of the coke oven to the blower Will air leak in from the gas holder inlet to the Roots blower room? I would like to ask whether companies such as Hebei Jiantao and Shandong Shenglong are facing the same issue What is your oxygen level controlled at?
The quality of coal varies from region to region, and as a result, the composition of the coke oven gas produced upon combustion also differs
Our coal supply is relatively stable; judging from the occasional increase in oxygen content in the coke gas, it seems that it’s not a problem with the quality of the coal. We have analyzed the impact of quality. Thanks for the discussion on floor 2; I’ve been arranging for the laboratory to check this issue these past few days
Poor sealing of the coke oven doors can lead to high oxygen levels, and this is a common issue in our coke oven operations; efforts must be made to improve the handling procedures
