Seeking a renovation plan for the preheating coil in the methanol production plant using coke oven gas
Thread Content
Our facility produces methanol from coke oven gas, and the coiled tubes in the preheating furnace have deformed and sunk. I’m seeking help; anyone with a successful modification plan is kindly asked to share their insights. Thank you! ! ! ! ! !
Similarly, in the first five sets of 100,000-ton units, both Sinopec and Black Cat experienced this issue with their preheating furnaces; switching to the box-type furnaces designed by Tianchen Design Institute can resolve this problem. However, the investment required is relatively high, around 7 million yuan. With this change, the need for fans is eliminated, resulting in more stable operation. Fengxi in Yongji, Shanxi can do it.
