Analysis of the impact of hydrogenation on the circulation hydrogen volume due to changes in processing capacity
Thread Content
When the hydrogenation unit increases its processing capacity, the amount of circulating hydrogen decreases. After making adjustments, it is necessary to adjust the speed of the circulating hydrogen compressor to prevent the anti-surge valve from opening automatically, otherwise multiple streams of hydrogenated gas will lead to an automatic shutdown! When the processing capacity is reduced, the amount of circulating hydrogen increases; if the hydrogen-to-oil ratio remains unchanged, this leads to energy waste, so it is necessary to reduce the speed. (The new hydrogen compressor adjusts itself according to the system pressure in automatic mode or manually.) So, how does changing the processing capacity affect the amount of circulating hydrogen? Please help solve it, thanks to all the experts! ! ! ! !
After the processing capacity increases, the pressure drops in the heating furnace, reactor, and heat exchangers will all increase, which leads to a decrease in the circulation rate. What is the design and processing capacity of your equipment per hour? What will it be after the increase?
