Hydroxyethyl cellulose (HEC) is a common water-soluble polymer used in a wide variety of applications. Its application and classification are as follows: Application field: Construction and building materials: In the construction industry, HEC is used as a thickener for materials…
With the increasing attention to environmental protection in the world, the production of high-quality clean diesel has become the development direction of modern oil refining industry. Sulfur is the most harmful element that increases CH and CO in diesel engine…
Use: It has a good dispersion effect on insoluble suspended matter (such as catalyst powder) in the oil slurry of catalytic cracking unit, and prevents it from condensing and settling. Principle of slurry scale inhibitor First, the principle of action…
In the process of oil field production, due to the oil well products contain paraffin components, Paraffin is a solid substance in the crude oil, and the paraffin in the oil layer is dissolved in the crude oil. After being…
Water injection is a common stimulation technology in petroleum development. It can increase the bottom hole pressure, change the physical properties of the reservoir and reduce the viscosity of the reservoir by water injection treatment, improve the flow of crude…
This paper introduces the application of biological enzyme plugging agent as a sustainable and environmentally friendly plugging technology in underground gas storage. By selecting the appropriate bioenzyme solution and optimizing the conditions, we can effectively reduce the clogging problem in…
This paper introduces the application of a new type of polymer nanoparticle flooding agent in oilfield development. By modifying functional groups on the surface of polymer microspheres, they have excellent oil-water interaction ability, and these microspheres can be used to…
Corrosion inhibitor for refinery catalytic cracking is a special corrosion inhibitor, its main role is to protect the metal parts of refinery catalytic cracking unit (such as reactors, heat exchangers, condensers, pipelines, etc.) from the corrosion of media (such as…
Refinery high temperature oil soluble corrosion inhibitor is a chemical additive added to the refinery system to reduce the corrosion rate of metal materials under high temperature and high pressure environment. This corrosion inhibitor can be dissolved in fuel oil…
Reverse demulsifier is a chemical agent used to treat oil-water emulsions. It can destroy the emulsifier molecules in the oil-water emulsion and make it lose its stability, so as to realize phase reversal and separate the oil and water. It…
