Many people don’t understand what reverse demulsifiers are. There are many blind spots due to a lack of understanding of the principles of reverse demulsifiers and other related formulas. The term “reverse demulsifier” originates from the explanation of demulsifiers, which…
Demulsifiers are surfactants that break down emulsions. They primarily disrupt emulsions by partially replacing the stabilizing film. As dehydrating agents, they remove water from crude oil and heavy oil, achieving the required water content. In oil wells, they reduce crude…
I. Water Locking: A “Hidden Obstacle” in Oil and Gas Extraction During oil and gas field development, especially in the exploitation of low-permeability and ultra-low-permeability oil and gas reservoirs, as well as unconventional oil and gas resources such as shale gas…
1.Surface tension The contraction force of any unit length of the liquid surface is called surface tension, and the unit is N•m-1.2.Surfactants and surfactants The properties that can reduce the surface tension of solvents are called surfactants, and substances with…
Linear Alkylbenzene Sulphonic Acid (LABSA) is a commonly used anionic surfactant with a wide range of application scenarios in multiple fields. Due to its excellent decontamination, emulsification, wetting, dispersion and foaming properties, LABSA has been widely used in household cleaning,…
SLS (sodium lauryl sulfate) is an anionic surfactant widely used in daily chemical, food, pharmaceutical and other industries. The following is a detailed description of its production process. 1. Raw material preparation The production of SLS mainly uses the following…
1. Raw material preparation In the production process of SLES, the most critical raw material is Lauryl Alcohol, which is a long-chain fatty alcohol obtained from natural oils or petroleum derivatives, usually with a C12 carbon chain. In addition, Ethylene…
1. Introduction 1.1 Overview of sodium dodecyl sulfate Sodium lauryl sulfate (SLES) is an important anionic surfactant that is widely used in cleaners, detergents and personal care products. It is the preferred ingredient in many everyday chemicals due to its…
1. Overview 1.1 Definition and structureSodium Lauryl Ether Sulfate (SLES) is a commonly used anionic surfactant used in a wide variety of cleaning products. Its chemical structure is RO(CH2CH2O)nSO3Na, where R is dodecyl. 1.2 Importance SLES is an important ingredient…
