Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] see figure 2 , figure 2 It is a schematic diagram of a device for regenerated gas recycling and recycling of regenerated gas according to an embodiment of the present invention.
[0034] Such as figure 2 As shown, when the MTP device normally carries out the reaction of methanol to propylene, the first valve group 234 is completely closed, the eighth valve 1061 is opened, the methanol raw material enters the reactor 101 through the normal feed pipe...

The invention discloses a device and method for recycling regeneration gas. The regeneration gas flowing in from the regeneration gas feed line reacts with the catalyst in the reactor to improve the activity of the catalyst, and the reacted regeneration gas waste gas is output from the output end of the reactor through The heat exchanger enters the separation tank after exchanging heat, and after the separation tank flashes the regeneration gas waste gas, the gas phase regeneration gas waste gas is output from the top of the separation tank and passes through the gas phase output pipeline and is transferred by the first gas phase output sub-pipeline and the second gas phase output sub-pipeline. The pipeline is divided into two streams, the stream in the first gas phase output sub-line is used for recycling, and the stream in the second gas phase output sub-line is discharged or burned; the flow controller is collected by the first flow transmitter and the gas emission analyzer The ratio of the stream flow of the second gas phase output sub-pipeline and the key components in the regeneration gas waste gas is calculated and controlled by the valve to adjust the ratio of the new regeneration gas and the recycled regeneration gas waste gas, so as to ensure the key components of the regeneration gas entering the reactor. Divided into preset density values.
Description
technical field [0001] The invention relates to the field of catalyst regeneration, in particular to a device and method for recycling regeneration gas of a reactor of an MTP (Methanol ToPropylene, methanol to propylene) device. Background technique [0002] In existing plants, the reactor usually needs to be regenerated. When the equipment that needs to be regenerated is switched from the normal operation condition to the regeneration condition, it usually needs to go through the steps of material return, pressure relief, replacement, purging and regeneration. In the steps of replacement, purging and regeneration, regeneration gas is usually used to treat the catalyst or desiccant in the equipment. The regeneration gas entering the equipment usually uses fresh inert gas or gas that does not affect the performance of the catalyst in the equipment. After the regeneration gas enters the equipment, it reacts with the carbon deposits / impurities on the surface of the catalyst, ...
