Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a storage device, a method, device and equipment for predicting product distribution of hydroisomerization. Background technique [0002] The hydrogen system of an oil refinery usually consists of a hydrogen supply unit, a hydrogen consumption unit, a hydrogen recovery unit, and a hydrogen pipeline network. Among them, the hydrogen pipeline network acts as a bridge connecting the hydrogen supply unit, the hydrogen consumption unit and the hydrogen recovery unit, and is a hydrogen resource. An important basis for optimization to be achieved. The main functions of the hydrogen pipeline network are: transporting hydrogen of various purities to the hydrogen consumption unit; responsible for transporting the exhaust gas of the hydrogen consumption unit to the hydrogen recovery unit or gas system; at the same time, maintaining a stable pressure field, The velocity field ensures t...
