Steam stripping cooling equipment and method for regenerated catalyst

Abstract

The invention discloses steam stripping cooling equipment and method for a regenerated catalyst. The equipment comprises a first steam stripping section (31) and a cooling section (2) which are arranged in a barrel body of the steam stripping cooling equipment, wherein a catalyst inlet and a catalyst outlet (4) are respectively positioned at the top and the bottom of the barrel body of the steam stripping cooling equipment. The first steam stripping section is provided with grating fillers (8) or steam stripping baffles, and each group of grating fillers or steam stripping baffles are arranged at intervals along the axial direction of the barrel body of the steam stripping cooling equipment. A first steam distributor (5) is arranged below the group of grid packing or steam stripping baffles at the bottom; and a cooling section is provided with a heat removal pipe (1). The first steam stripping section is positioned above the cooling section, and a second steam distributor (6) is arranged below the cooling section. The invention discloses a method for stripping and cooling the regenerated catalyst by adopting the equipment. The equipment can be widely applied to various devices for catalytic cracking, oxygen-containing compound catalytic conversion and the like, and is used for stripping and cooling a regenerated catalyst carrying gas impurities.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and coal chemical industry, and relates to the stripping of the regenerated catalyst in the continuous regeneration process of catalytic cracking of hydrocarbon raw materials and the production of olefins (mainly ethylene and propylene) from oxygen-containing organic compounds represented by methanol or dimethyl ether Cooling apparatus and methods. Background technique [0002] Catalytic cracking is an important process in petroleum refining and petrochemical industry. With the increasing demand for chemical products, fluidized catalytic cracking technology is widely used in hydrocarbon conversion processes for the production of chemical products, such as HCC process (heavy oil contact cracking process), CPP process (catalytic thermal cracking process), MTO process (methanol Olefin process), FMTP process (methanol fluidized bed to propylene process), MTA process (methanol to aromatics proces...
