Abstract

The invention provides a gas condensate deodorization method. The method comprises the following steps of mixing or contacting gas condensate, an activator, an oxidizing agent and a deodorization catalyst, and collecting the mixed or contacted gas condensate, wherein the activator comprises a mixture of a water-soluble ether compound, inorganic base and / or organic base, and a water-soluble polar solvent, the water-soluble ether compound has a structure of R1(OR2)nOR3, R1, R2 and R3 respectively represent C1-C8 alkyl and n is an integer of 1-5. The gas condensate deodorization method transforms low-boiling point sulfide in the gas condensate into high-boiling point sulfide thereby realizing deodorization, can be operated simply and safely, does not discharge waste, is suitable for oil field, harbor, oil depot and oil refinery and is conducive to follow-up processing of gas condensate. The gas condensate deodorization method has lasting deodorization effects, can substantially improve smell, directly improves gas condensate corrosivity to a distillation column, reduces sulfur content of a follow-up product and desulphurization load in processing and reduces desulphurization sewage.

Description

technical field

[0001] The invention relates to a method for deodorizing condensate oil. Background technique

[0002] As we all know, condensate comes from the liquid phase components associated with the exploitation of associated natural gas in oilfields, and its main component is C 2 ~C 20 A mixture of hydrocarbons, but containing a certain amount of colloid and asphaltenes, belongs to the category of crude oil, and is a high-quality raw material for the production of solvent oil, naphtha, and aviation kerosene, but it often contains highly volatile hydrogen sulfide, mercaptan, etc. Malodorous and toxic sulfides, sometimes containing more than 1000mg / kg, resulting in a concentration of such sulfides in the gas phase as high as 2200mg / m2 at room temperature 3 . Due to the high corrosiveness and strong toxicity of sulfides, high-sulfur condensate will cause severe corrosiveness to metal and rubber materials, personal safety due to volatilization during storage and transp...
