Crude Oil Desalters And Their Most Common Methods

A crude oil desalter is a device used extensively in the oil industries and refineries to remove inorganic salts, water, and sediment from incoming petroleum crude oil. 

The removal of salts, water and sediments is essential for avoiding the corrosion generated by hydrochloric acid by the hydrolysis of chloride salts present in the processed crude oil (magnesium chloride and calcium chloride). Any salt that is not removed, acts as a threat that can poison potential catalysts used in various petroleum refinery processes. 

Common methods of crude oil desalting

  •   Chemical and electrostatic separation - Washing of the salt from crude oil with the help of water oil and water phases are separated in a settling container. In the next step, chemicals are added to break up the emulsion to calm down the saltwater droplets more rapidly.
  •  Chemical desalting - Demulsifiers, which are the water and chemical surfactant, are added to crude and then heated so that salt and other impurities dissolve into the water, after which they settle down.
  •  Electric desalting - Under charge, the polar molecules get oriented and separated. More than 90% of the salt can be removed in less than half an hour by this technique.
You can find a number of online stores where you can buy crude oil refinery desalters. In case you are looking for specific oil refinery spare parts, you can also ask assistance from these service providers. Managing a refinery is no easy task, so it is best to keep it in safe hands.

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.  Emulsifi

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 Major Applications Of PTFE In Various Industries

Image
Polytetrafluoroethylene (PTFE) is one of the most remarkable polymeric materials used for coating cooking utensils and industrial applications where sticking is avoided. This synthetic compound has been a great invention that helps human civilization progress in many ways. Here are three primary uses of PTFE in industrial sectors. Petrochemical plants In a petrochemical plant, some processes involve transporting corrosive chemicals through pipes across the facility. This activity is vulnerable to leaking and explosions if the pipe materials are of inferior quality. To avoid the risk, industrial plants use Teflon standoff insulators to ensure safety . Famous for being non-stick, heat, and chemical resistant, PTFE is an ideal choice for coating pipelines and hoses that transfer petroleum products and corrosive chemicals from one unit to another. Automotive When manufacturing vehicles, there is a need for many materials, including metal and non-metal substances, to assemble vario
