【Q&A Question 215】August 09, 2018: Briefly explain the purpose of conducting hot oil circulation in the distillation system of a newly built plant The hot oil circulation in newly installed units is used to flush out any debris remaining in the pipelines and equipment that were not involved during the water circulation process, thereby keeping these pipelines and equipment clean. Taking advantage of the strong penetration ability of coal and diesel distillates, it is possible to detect leaks promptly and carry out repairs. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

1. Test equipment and pipelines that are in a heated state during normal operation, such as heating furnaces and hot oil pumps； 2. Thermally tighten the flanges in high-temperature areas.
Identify potential issues and address them； Such as control valve failures, pump failures, etc

The hot oil circulation in newly installed units is used to flush out any residual debris in pipelines and equipment that was not cleaned during the water circulation process, thereby keeping these pipelines and equipment clean. Taking advantage of the strong penetration ability of coal and diesel distillates, it is possible to detect leaks promptly and carry out repairs； Check the operation of instruments such as temperature control and level control devices ； Examine the changes in pumps, equipment, etc. when oil is supplied ； Through hot oil circulation, the distillation system establishes a stable oil flow, enabling rapid oil withdrawal once the reaction system is ready for operation and thus reducing the startup time of the distillation system ； Simulate actual operations at the same time to provide pre-training for them.
