Abstract

The invention discloses an MTP (Methanol to Propylene) and catalytic cracking combined technology and an integrated unit, and belongs to the technical field of petrochemical refining. In the MTP and catalytic cracking combined technology, an MTP reaction system includes an MTP reactor; a catalytic cracking system includes a catalytic cracking reaction-regeneration system, a catalytic cracking fractionating system, and a catalytic cracking absorption-stabilizing system. The MTP and catalytic cracking combined technology is characterized in that material flows out from the MTP reaction system after reaction is subjected to heat exchange and cooling, and then is injected with water and pressurized through a high-pressure water pump; the pressurized material is directly sent to an oil-gas separation tank of the catalytic cracking fractionating system for the separation of the oil phase, gas phase and water phase, the separated gas phase and oil phase enter the catalytic cracking absorption-stabilizing system for follow-up treatment. According to the invention, the MTP technology is combined with the catalytic cracking technology, the catalytic cracking fractionating system and the catalytic cracking absorption-stabilizing system are fully utilized, a separating system of the MTP device is dispensed with, so that the investment is reduced.

Description

technical field [0001] The invention relates to a combined process of a methanol-to-propylene (MTP) process combined with a catalytic cracking process of petroleum refining, belonging to the technical field of petrochemical product refining. Background technique [0002] Catalytic cracking unit is an important refining unit in petrochemical industry, which mainly includes reaction-regeneration system, fractionation system, absorption-stabilization system. The methanol-to-propylene MTP plant is a device downstream of the coal chemical industry. It mainly includes a reaction system and a separation system. Like most coal chemical plants, the MTP plant has a huge investment. [0003] The study found that the separation system of the MTP unit is similar to the fractionation stabilization system of the catalytic cracking unit, and the composition of the reaction discharge of the MTP unit is similar to that of the fractionation tower top discharge of the catalytic cracking unit. A...
