The heating time for high-temperature fractions is longer

Why is it that during the commissioning of a diesel hydrogenation unit, addressing the issue of hot high-pressure conditions takes a long time and is not easy? Is there any good way?
Thank you for posting in the production area; due to issues related to hydrogenation, it has been moved to the petrochemical hydrogenation forum. I hope fellow users can help resolve your problem promptly!
During the check of the forward high-temperature exchange, the bypass control valve is usually used during the temperature increase process~~~~ Without heat exchange with the feed oil, the temperature can rise a bit faster~~~~
Didn’t understand your question? What is 95? The temperature of the hot high-pressure stream is determined by the reactor outlet and the heat exchange rate; at the beginning of operation, when the reaction cycle starts, the temperature is not high, so it is necessary to wait for the hot oil to be replaced before the system can operate stably
Increase the circulation rate; the temperature of the hot fraction cannot rise. The problem usually lies at the bottom, so release some fluid from the hydraulic control valve towards the lower fraction
Mm-hmm, good idea. The flow at the bottom isn’t very good; increase the gas flow and raise the speed of the circulator as well
