Embodiment 1

[0054] In a 1 million tons / year residual oil hydrotreating process, according to the method of the present invention, the high temperature and high pressure separator of the cyclone enhanced separation method is used to treat the high pressure multiphase mixture containing solid catalyst, liquid particles and gas Two-stage series cyclone enhanced separation is carried out to achieve the purpose of effectively separating liquid particles and gases in high-pressure multi-phase mixtures with extremely low pressure drop. The specific operation process and effect are described as follows:

[0055] 1. Material properties and related parameters

[0056] The high-pressure multi-phase mixture is circulating hydrogen gas with liquid droplets and solid catalysts in it, wherein circulating hydrogen is the continuous phase medium, and oil, liquid droplets and solid catalysts are the dispersed phase medium. The processing capacity of circulating hydrogen gas is 38910kg / h, and the gas phase ...

Abstract

The invention relates to a two stage cyclone series connection strengthening separation method for a reaction product in a suspension bed hydrogenation process, and an apparatus, and provides a two stage cyclone series connection strengthening separation method for a reaction product in a suspension bed hydrogenation process. The method comprises: carrying out first-stage cyclone separation on a reaction product from a suspension bed reactor to remove most of liquid droplets and solid catalyst particles; and carrying out second-stage micro-cyclone separation on the reaction product separated through first-stage cyclone separation to separate colloid substances, asphalt substances and solid catalyst particles entrained in the reaction product. The present invention further provides the two stage cyclone series connection strengthening separation apparatus for the reaction product in the suspension bed hydrogenation process.

Description

technical field [0001] The invention belongs to the technical field of petroleum processing, and relates to a separation method and device for strengthening the separation of a three-phase mixture of gas, liquid and solid by adopting two-stage cyclone in series, which is suitable for processing gas with high liquid content and high solid content. , liquid and solid three-phase mixture. Specifically, the present invention provides a two-stage cyclone series enhanced separation method and device for reaction products in a suspended bed hydrogenation process. Background technique [0002] In the petroleum refining industry, the vacuum residue is mixed with additives, hydrogen, etc., and then enters the suspension bed reactor for hydrocracking after being preheated by a high-pressure feed pump. The product after the cracking reaction enters the separator for separation, and the solid and liquid mixture separated by the separator enters the vacuum flash tower to recover distilla...
