Problems of non-catalytic oxidation of coke oven gas to methanol
Thread Content
Dear friends, I saw that in the non-catalytic oxidation process of coke oven gas to methanol, wet desulfurization is designed to be placed after conversion, resulting in the loss of carbon dioxide in the raw gas. Why not put wet desulfurization before conversion? Isn’t the carbon dioxide content in the coke oven gas before conversion smaller?
1. We use dry desulfurization. 2. Wet desulfurization currently removes up to 60% of organic sulfur. 3. After conversion, all organic sulfur is converted into inorganic sulfur at more than 1,000 degrees, which is easy to remove.
You read that right. In general, wet desulfurization is done before conversion, and only dry desulfurization is done after conversion. Ours was designed by Tianyi, and the Second Chemical Institute also used wet method first. I haven't heard of the wet process after conversion. Please check again.
I'm talking about the non-catalytic partial oxidation process. It is not a catalytic oxidation process. As far as I know, only Ningdong Baofeng has this kind of craftsmanship.
