Demulsifier

Application:

These materials cause the separation of water from the water/oil emulsion and prevent problems such as corrosion, difficulty in transferring oil and reducing the quality of oil.

Product Introduction:

By using several methods such as mechanical methods (including filtration, thermal treatment techniques and even membrane separation), thermal, chemical or even electrical methods, water dispersed in oil can be separated. Determining the characteristics of the emulsion is important to identify the best method to use.

Among the mentioned methods, the best and most economical method is the chemical suspension process. Based on this, a suitable demulsifier with the lowest possible concentration should be used, which can completely separate the water at a low operating temperature and reduce the salt to the lowest possible level in the shortest possible time.

Technical Specifications:

The demulsifier breaks the water-in-oil emulsion and separates the water from the produced oil. The demulsifier, in contact with the water-in-oil emulsion, weakens the electrostatic forces of repelling water droplets and eventually causes the droplets to collect together.

This process includes the following two steps:

* Flocculation: tiny water droplets are connected to each other and appear in the form of clusters.

* Coagulation: binding of water molecules. Solid wetting: With this process, physical separation takes place and water is placed at the bottom. It is necessary to investigate various factors affecting the performance of demulsifiers, such as the rheology of interfacial properties, the amount of hydrophilicity and hydrophobicity, the rate of mass transfer from the demulsifier to the interface, etc. One of the characteristics of a suitable demulsifier is the maximum separation of water from crude oil with the minimum amount and concentration of demulsifier used at the lowest operating temperature and the shortest time. Demulsifiers are a combination of different materials, including acid or base catalyzed phenol formaldehyde resins, polyols, polyamines, polyethylene imines and even epoxy resins. The main component of these materials is based on polymer or copolymers, which must be ethoxylated or propoxylated in a controlled manner before use. The product is a formulation of one or more of the aforementioned ethoxylated or propoxylated polymers along with some additives, including alkyl aryl sulfonic acids, fatty acid esters, ethers and esters of bis-phenol glycol, sodium dodecyl sulfate, etc. These additives are soluble in solvents such as xylene, heavy aromatic naphtha, isopropanol, methanol, ethylhexanol, etc. Their composition is done in certain percentages, which need to be changed according to the specifications of the oil extracted from each oil field.

Advantages:

* Customization for each oil field

* Reasonable price

* High quality
