Description

technical field

[0001] The invention relates to the technical field of oil refining and processing, in particular to a hydrogen distribution prediction method, device and equipment for storage and oil refining production equipment. Background technique

[0002] Crude oil processing is actually a process of rebalancing and redistribution of hydrogen. The crude oil is divided into distillate oils with different hydrogen distributions according to the difference of boiling point through the atmospheric and vacuum device. Atmospheric distillation and vacuum distillation are both physical processes. The desalted and dehydrated mixed raw oil is heated in the distillation tower. According to the difference in boiling point, it is divided into oil products with different boiling points from the top to the bottom of the tower, which are distillates. Some of these distillates leave the factory in the form of products after being blended and added with additives, and most of them are ...
