Case Study on Top Control of a Stripper in Winter

Thread Content

In the device I worked on previously, which was used for diesel hydrogenation, during winter, due to the lower volume of processing, the air cooler at the top of the tower froze as a result of flow imbalances, causing pressure buildup at the top of the tower； As the pressure kept rising, the vents at the top of the tower were opened to relieve pressure and maintain normal production, after all, the amount of gasoline was low. Steam was injected from behind the air cooler, in front of the water cooler; the inlet to the air cooler was closed, and a tarpaulin was placed on top of it to maintain heat. Within one afternoon, the contents inside the air cooler melted ； Therefore, going forward, we will pay special attention to operations in winter, especially at the areas of the stripping tower and other locations where salt buildup is likely to occur ； I hope everyone and those with more experience can give me some guidance! ! !
