How one can derive Minimum Allowable Pressurization Temperature for a typical reactor? What is the procedure to work-out maximum allowable heat-up and cool-down rates for hydrocracking/treating reactor vessels?

I agree with Mr. Saleh Daryabari response on MPT The maximum heat rate is depend on various factors and is about 30 to 40 degree C.

Minimum Pressurization Temperature (MPT) is depends on reactor metallurgy. You should ask reactor manufacturer for this information.
You can achieve maximum heat-up and cool-down rates by oil circulation and bypass some preheat exchanger.
