Abstract

The invention discloses a hydrocracking reaction effluent air cooler system based on unbalance degree analysis. Including the inlet pipe part, the air cooler tube bundle part and the outlet pipe part. The inlet and outlet pipes of the hydrocracking reaction effluent air cooler system are arranged in strict accordance with balanced pipes, which avoids the problem of bias flow caused by fluid inertia caused by pipes branching in the same plane. The feed inlet of the tube bundle part of the air cooler flows into the tube box horizontally, and a distribution orifice is added in the tube box to make the three-phase distribution of the fluid medium even. The arrangement of the tube bundles in the tube box is improved from the commonly used double-row arrangement to a single-row arrangement, which can effectively reduce the three-phase bias flow of the medium. The pipe box structure adopts a detachable structure, which can make the manufacture and installation of the pipe box, fins and liner more convenient and reliable, and at the same time facilitate maintenance and replacement. Through this system, the operation reliability of the hydrocracking REAC system can be effectively improved, the occurrence of unplanned shutdown accidents can be reduced, and the economic benefits of the enterprise can be improved.

Description

technical field [0001] The invention relates to a hydrocracking reaction effluent system structure applied in the petrochemical industry, in particular to a hydrocracking reaction effluent air cooler system based on unbalance degree analysis. Background technique [0002] The petrochemical industry is an important foundation of energy, and the petrochemical industry is the pillar industry of our country. In the petrochemical industry, hydrocracking is an important secondary processing method in refineries, and the hydrocracking air cooler is one of the important equipment in the hydrocracking unit. It is located at the end of the reaction effluent heat exchange process. The effluent is cooled from 16MPa and 160°C to 49°C by the air cooler system, and then the circulating hydrogen, sulfur-containing sewage, low-content dry gas and low-oil content are separated by high-pressure separator and low-pressure separator. [0003] Since the hydrocracking process is a typical multi-p...
