3 Steps Involved In The Desalting Process

When it comes to oil-refining, you cannot take any chances. As desalting is vital for the purification of crude oil, you need to ensure that the equipment being used in your industry functions efficiently. To do this, you need to use the best desalter for crude oil in your industry. However, before you check the desalter in your refinery, it will help if you had the necessary information about the steps involved in the process.

Here are some of the steps involved in the desalting process you should know about.

1. Dilution of Water

The first step in the desalting process is the dilution of water. In this step, the water passes through the preheat train and pumped to the desalters. Thereafter the water that is recycled from the desalter enters the static mixer and injected. It ensures optimal contact with the surface of both the fluids needed for the process.

2. Emulsification of water

The second step in the process is the emulsification of water. The diluted water is emulsified with oil. The purpose of this step is to avoid the first separation with oil. Then the static mixers act as the emulsifying devices that help in improving the contact between the crude oil (salt) and the injected wash water from the source.

3. Distribution of emulsion

The third step involves the distribution of emulsion. This happens in the electrostatic field in the desalting process. The mixture which contains oil and water is then emulsified uniformly across the field. After the other treatment, the emulsion enters the Desalters where it is segregated into two separate phases by electrostatic coalescence.

Conclusion

After these steps, some of the other steps involved in the process include electrostatic coalescence and the settling of water droplets in the system. When you get the best desalter for crude oil in your industry, all these processes can be performed with ease.

3 Crude Oil Desalting Methods And Benefits Of Using Desalters Over The Other Two

Refineries are a complex set of operating units specifically designed to process crude oil into refined products like jet fuels, gasoline, diesel, and hundreds of other products that people use every day. The refinery process constitutes desalting as the first step of the overall process. The desalter bought from recognized desalter unit suppliers can efficiently remove most of the impurities from the raw oil. As a result, almost all refineries now use electrostatic desalters because removal of salts, water, and sediment is considered necessary to avoid excessive fouling of equipment and corrosion from generated HCl due to the presence of chloride salts. However, note that though desalting using desalters is the most efficient method of removing impurities, it isn’t the only one. 3 Potential Methods Of Desalting Of Crude Oil - Mechanical In the case of the mechanical method, heated crude is mixed with wash water left in a large vessel for settling down water drops because of gravity. ...

3 Primary Components that are a Part of Commercial Boilers

A boiler is basically is advanced, pressurized setup where combustible fuel is burned to increase the temperature of the water. Few specific types of boilers spread the hot water, and in some setups, the water is used that has transformed into steam. The steam is circulated by using high-grade pipes. These pipes enter the radiators (other heater types in some cases) throughout the commercial environment. This helps keep the spaces warm and comfortable for the users. Natural gas is a popular and most commonly used fuel for commercial boilers. In the next part of the post, we are going to discuss the three key components of commercial boilers. Burner - It is that specific part or component where the air mixes with the combust, as well as the fuel sources. For this to work well, you need to input the right amount of combustion air. This will also ensure clean and efficient combustion. Too little or too much air won’t allow for complete combustion. Combustion Chamber - The combustion chamb...

How Desalination Works In Oil And Gas Industry

Image
Desalination is the process of purifying saline water by removing salt and other impurities from the crude oil to obtain oil and petroleum products. For years, various types of desalination technologies have been used in oil and gas companies. From oil and gas to Texas construction of desalination plants , the trend continues to serve the industry for various purposes. The desalination process usually includes dilution water injection and dispersion, emulsification of diluted water, distribution of the emulsion in the electrostatic field, and electrostatic coalescence. Desalting  Crude oil recovered from the earth’s crust is mixed with gases, water, chloride salts, and dirt, which contain other minerals. The oil is then transferred to the processing plant using a pipeline. The process of desalting consists of mixing heated crude oil with washing water. In a separate vessel, the process of emulsification is conducted to prevent emulsions during the process.  ...
