Description
Technical field
The present invention is specifically related to a kind of chilled water (chw) demulsifier composition, a kind of chilled water (chw) demulsifier and application thereof.
Background technology
The ethylene unit cracking gas is behind the quenching oil column oil wash, enter water scrubber, through the chilled water (chw) spray, the cracking gas temperature is chilled to about 40 ℃ from about 100 ℃, heavy components such as steam in the middle of the cracking gas and drippolene will enter the profit subsider and carry out water-oil separating under the condensation of washing Tata still.Chilled water (chw) part after the separation enters the dilution steam generation generator, and another part recycles.Yet owing to usually emulsification can take place between chilled water (chw) and the drippolene; cause chilled water (chw) emulsion band oil; chilled water (chw) emulsion band oil can cause the fouling of dilution steam generation generator; be unfavorable for that the dilution steam generation generator conducts heat; be unfavorable for dilution steam generation generator generation dilution steam generation; be unfavorable for reducing the fresh water (FW) discharge capacity, be unfavorable for the ethylene unit energy-saving and emission-reduction.
The main cause that causes chilled water (chw) emulsification is to contain heavy component in the drippolene, and it can form the O/W type emulsion that droplet diameter is 0.1～2 μ m with chilled water (chw), makes the chilled water (chw) oil content up to more than the 1000wppm.The main cause of this class emulsion energy stable existence is that the positive charge of opposite charge is the Ster layer with regard to forming an electric double layer nearby therewith because oil droplets is electronegative.Between the surperficial electronegative oil droplet repulsive interaction is arranged, make oil droplet be difficult for flocking together, make profit be difficult to separate.
Proposed some both at home and abroad and solved the method for chilled water (chw) O/W type emulsification problem, proposed a kind of method that adopts water-soluble cationic polymer to solve the chilled water (chw) emulsification problem as US5294347; The chilled water (chw) demulsifier HK-1412 of Zhejiang Province HanghuaTechnology Co., Ltd's exploitation (sees 2008-2009 state key new product planning established project inventory, numbering: 2008GRC20072) also can be used for solving the chilled water (chw) emulsification problem.
Above-mentioned demulsifier main component all is a cationic surface active agent, all can by in and the oil droplets negative electrical charge reach the breakdown of emulsion purpose, but also need stop the time of growing in the middle of oil-water separation tank could satisfy the water-oil separating requirement.
Summary of the invention
Technical problem to be solved by this invention is also need to stop the time of growing behind the existing chilled water (chw) demulsifier could satisfy water-oil separating and require this defective in the middle of oil-water separation tank in order to overcome to use, and a kind of chilled water (chw) demulsifier composition, a kind of chilled water (chw) demulsifier and application thereof are provided.Chilled water (chw) demulsifier of the present invention can quicken water-oil separating after joining in the middle of the chilled water (chw) of turbulent flow effectively, reaches the purpose of breakdown of emulsion fast.
The inventor finds that after aliphatic acid and alkylamine, generated oil-soluble cationic surfactants, this cationic surfactant, unreacted aliphatic acid or alkylamine and varsol have been formed chilled water (chw) demulsifier of the present invention.After this demulsifier being joined in the middle of the chilled water (chw) of turbulent flow, active ingredient wherein can be rapidly near oil droplets, then in and negative electrical charge.After the oil droplets electric charge was neutralized, the repulsive interaction between the oil droplet diminished, and oil droplet flocks together easily, thereby quickened water-oil separating, reached the purpose of breakdown of emulsion.
