Abstract

The invention relates to the technical field of preparation of scale inhibitors, in particular to a scale inhibitor suitable for an S Zorb gasoline desulfurization device as well as a preparation method and application of the scale inhibitor. Comprising the following raw materials in parts by mass: 12-17 parts of an antioxidant, 7-11 parts of a hydroxylamine polymerization inhibitor, 6-9 parts of polyisobutylene diimine, 7-9 parts of iminodisuccinate, 4-6 parts of a viscosity modifier, 5-8 parts of modified activated carbon, 7-10 parts of ammonium persulfate, 5-7 parts of oil-soluble imidazoline and 53-74 parts of 120 # solvent oil. The scale inhibitor is added into the raw material catalytic gasoline, so that colloid aggregation and olefin condensation reaction in the gasoline can be avoided, the scaling phenomenon of a heat exchanger tube bundle is effectively prevented, meanwhile, the adhesion rate of dirt in subsequent desulfurization operation can be reduced, and peculiar smell in a desulfurization device can be eliminated.

Description

technical field [0001] The invention relates to the technical field of scale inhibitor preparation, in particular to a scale inhibitor suitable for an S Zorb gasoline desulfurization device and a preparation method and application thereof. Background technique [0002] S Zorb process is a reactive adsorption desulfurization process, which combines fluidized bed reactor and continuous regeneration technology, and has been successfully applied to the desulfurization of catalytically cracked gasoline. It is currently the most widely used adsorption desulfurization technology in industrialization. In the existing S Zorb adsorption desulfurization device, since the raw catalytic gasoline contains colloids and olefins and other components, in the process of heat exchange and temperature rise, the colloids will accumulate on the tube bundles of the heat exchanger, and part of the olefins will be heated and gasified. During the process, coke-like coke will be condensed and attached ...
