Application of demulsifier:

A demulsifier is a chemical used primarily to separate and purify emulsions, but can also be used to break up emulsifying systems. Demulsifier is an indispensable and important industrial auxiliary agent in petroleum, chemical industry and dairy industry. This paper will introduce the use, application and precautions of demulsifier.

First, the use of demulsifier

1. Separation and purification of emulsion: Emulsion is a complex mixture consisting of two components: water and oil. Demulsifier can separate the water in the emulsion, so as to achieve the purpose of separation.

2. Destruction of emulsifying system: Emulsifying system refers to a stable liquid state formed after mixing two or more insoluble liquids. The demulsifier can destroy the emulsification system, so that the oil-water mixture becomes the water-oil mixture, so as to achieve the purpose of separation.

3. Remove fine particles in oil-water separation: oil-water separation refers to a suspension formed by mixing oil and water. Demulsifier can remove fine particles in the oil-water separation and turn it into a uniform suspension.

Second, the use of demulsifier

1. Select the appropriate demulsifier according to needs: Select the appropriate demulsifier variety and concentration according to needs, usually need to conduct small and pilot tests to determine the best conditions of use.

2. Select the appropriate use method according to the system: Select the appropriate use method according to the system, such as demulsifier can be directly added when separating and purifying the emulsion; When destroying the emulsion system, it is necessary to dissolve the demulsifier in water first, and then add it to the emulsion system.

3. The amount and method of addition of demulsifier: according to the nature and needs of different systems, the amount and method of addition of demulsifier can be determined, such as directly adding, spraying or diluting in water.

Third, the use of demulsifier precautions

1. Choose the right demulsifier variety and concentration: Choosing the right demulsifier variety and concentration is a key factor in the use of demulsifier, and it is necessary to conduct small and pilot tests to determine the best conditions of use.

2. Pay attention to the addition method and timing: the addition method and timing of demulsifier are also important factors affecting the demulsification effect, and need to be adjusted according to the nature and needs of the system.

3. Pay attention to the treatment equipment and working environment: When using demulsifier, pay attention to the treatment equipment and working environment, such as selecting the appropriate treatment equipment and maintaining good ventilation conditions, so as to avoid safety risks.

In short, demulsifier is an important chemical substance, widely used in petroleum, chemical industry, dairy industry and other industries. When using demulsifier, it is necessary to select the appropriate variety and concentration according to the actual situation, and pay attention to the addition method and timing to ensure the demulsifier effect and production safety.
