Yanshan, Tianjin, Jinshan, Guangzhou, Maoming, Zhanjiang
We can do it; both of the large refineries in Dalian should work fine. But be careful with the heat exchangers for raw materials and products – if there is a slight internal leakage, that could cause problems

However, this requires long cycles for the unit. Since the feedstock is supplied directly from upstream units, fluctuations in the feed amount can lead to significant variations in the composition of the crude oil, which in turn causes fluctuations in the reactor temperature and system pressure. This has a considerable impact on the hydrogen production unit as well. Also, if the accumulation of volume in the downstream tank area is not easily detectable from the distillation section, this leads to a rapid rise in the level of the first buffer tank, followed by a series of fluctuations.
