Coking unit high-temperature heavy oil filter
Thread Content
Regarding the operating conditions of coking units, high-temperature heavy oil filtration is carried out in the reaction and distillation sections of these units. Due to the differences in the raw materials processed and the production processes used, the filters at the inlet of the oil rejection pumps as well as those at the inlet of the bottom circulation pumps often get clogged, requiring regular cleaning. Could you discuss how your unit operates to reduce the frequency of filter cleaning? How is the cleaning process carried out? ? ? ?
Discuss how your device reduces the frequency of filter cleaning during operation To address this issue, start by focusing on the reaction unit; in terms of operation (stable operation, consistent process parameters, etc.), it is essential to control the height of the coke tower properly to prevent foam formation due to excessive height. How is the cleaning process carried out? ? ? ? 1. Switch to the backup according to the steps; after shutting down the operating unit, allow it to cool down naturally ； 2. After cooling, the temperature begins to drop; once it falls below 200 degrees, steam is used for dehydration and purging to remove oil ； 3. Begin pressure release, carry out cleaning, reinstall, preheat, and put it in standby mode. These are the general steps
