desalters

Once the primary oil or water separation is done, often times a small percentage of unwanted salts in the residual water gets deposited in the crude oil. This form of a contaminant can degrade the oil quality so it is necessary to get rid of this. If getting rid of it (100 percent) is not possible, the oil needs to be reduced to a concentration of about 5-10 PTB (pounds per thousand barrels) of salt. Successful removal of the salt will ensure the crude oil to be processed in a refinery or a stabilizer plant without fouling heaters, exchangers and other machineries. Crude oil desalting technology has come a long way and now this can be used to completely eliminate residual salt to meet various requirements. Size and type of the desalter that is used for the operation relies on a number of fundamental factors that include: pressure, temperature, flow-rate and fluid viscosity. Customer requirements relating to maximum permissible salt in the product oil stream also plays a significant r

The use of heavy machinery is needed in applications where crude oil needs to be processed to remove impurities. Therefore, desalters make an important part of the machinery for use in gasoline. The desalter's primary function is to isolate crude oil from the oil's impurities. This can only be achieved if the crude oil equipment has electrostatic isolation. Some of the basics of the desalting process are explained below. It will help if you have the necessary information about them. What is electrostatic separation? The process of removing impurities from crude oil in a desalter is electrostatic separation. This serves the primary function of removing impurities from the oil, such as hydrocarbon oils, inorganic salts, sediments, and soil. The electrostatic desalters are designed specifically to eliminate the system's water-soluble impurities. This system effectively removes all the impurities in the upstream of the oil.
