ActiveCN109609178AFast demulsificationImprove water qualityDewatering/demulsification with chemical meansKetonic acidsSulfur
The invention relates to the technical fields of petroleum demulsifying agents and preparation thereof, and relates to a demulsifying agent for treating thick oil and a preparation method of the demulsifying agent. Raw materials of the demulsifying agent comprise a polyoxyethylene polyoxypropylene block copolymer, ketonic acid, alkynol and water. The polyoxyethylene polyoxypropylene block copolymer is heated in a reactor, and then is mixed and dissolved with the ketonic acid, the alkynol and water, so that the demulsifying agent for treating thick oil is obtained. The demulsifying agent for treating the thick oil has the characteristics of high demulsification speed and good water quality after separation, can particularly being used to solve the problem that an acid-containing demulsifying agent product corrodes equipment, and has good anti-rust and anti-corrosion effects. According to the invention, the preparation process is simple, large-scale production is facilitated, and the obtained demulsifying effect for treating thick oil has excellent demulsifying effect and dewatering performance. Meanwhile, the raw materials do not contain sulfur, phosphorus, aromatic rings, chlorineand the like which are harmful to human bodies and to the environment, so that the demulsifying agent accords with the concept of safe and environment-friendly production.

A non-sticky petrolatum anti-corrosion paste
ActiveCN105001775BGood anti-rust and anti-corrosion effectStrong adhesionAnti-corrosive paintsPolyurea/polyurethane coatingsCorrosion resistantStearic acid
The present invention provides a non-sticky petrolatum corrosion resistant paste, specifically a non-sticky petrolatum corrosion resistant paste for corrosion protection of tower bolt fasteners in electrical network power transmission line and the gaps between steel-frame structure and bolt fasteners. The non-sticky petrolatum corrosion resistant paste comprises by weight: 36%-42% of polyether polyol EP-330N resin, 24%-29% of vaseline, 3%-5% of organic bentonite, 5%-8% of a composite filler, 6%-8% of dinonyl barium naphthalene sulfonate, 0.1%-1% of chopped fiber, 6%-8% of lanolin, 8%-12% of stearic acid and 5%-7% of an HDI trimer (N3390). The non-sticky petrolatum corrosion resistant paste coats on the surface of a protected objective to form a flexible organic coating, and the coating layer is dense and has physical isolation protective effect; at the same time, non-sticky petrolatum corrosion resistant paste plays a good role in corrosion protection of the metals to be protected. The non-sticky petrolatum corrosion resistant paste effectively protects the bolt fasteners, and facilitates construction and post-maintenance and operation.
