How to crude oil desalting
25 Mar 2003 Paraffin in crude oil exerts a great influence on the electric desalting and dewatering process because paraffin leads to higher viscosity of crude Cold liquid carryover to downstream units and corrosion, among many others, are examples of issues caused by water and water-soluble salts in crude oil. 9 Feb 2012 A method of removing entrained salt containing water from an inlet crude oil, stream includes the steps of applying an electrical energy to at Clora Online process X-ray fluorescence analyzer accurately measures total chlorine in raw crude oil and desalted crude. Desalter performance can be In the desalting process, crude oil is contacted with hot water to remove impurities such as chloride salts and par- ticulate matter before continuing through.
Oil desalting systems provide protection to capital intensive processing equipment by removing the salt component from crude oil. There are many significant
6 Jul 2015 Crude oil that contains only 1.0% water with a 15,000-ppm salt content has 55 lbm of salt per 1,000 bbl of water-free crude. The chemical In the desalter, the crude oil is heated and then mixed with 5-15% volume of fresh water so that the water can dilute the dissolved salts. The oil-water mix is put into Oil desalting systems provide protection to capital intensive processing equipment by removing the salt component from crude oil. There are many significant In one embodiment, the invention is related to a process for desalting crude oil that requires less wash water than conventional desalting methods. A process for desalting a crude oil comprises (1) injecting steam into the oil to form a steam-injected oil; (2) adding water to the steam-injected oil to form a Mature crude oil fields are often prone to high water cuts and high content of fines . The large population of small water droplets and fines forms very stable crude Schlumberger Process IQ software is a digital solution that maximizes electrostatic desalter & dehydrator performance & reliability.

Insoluble inorganic chlorides are difficult to remove during the crude-oil electrical-desalting process. When the temperature of the crude oil and the AGO in the CDU increases, however, the hydration rate speeds up rapidly, and the inorganic chlorides hydrate into free chlorine ion (see box). From the CDU,
2 1.1. As oil production is often accompanied by significant amounts of water, it is necessary to provide desalting and dehydration systems to separate the oil and water before the oil can be sold. Oil desalting and dehydration process is the process of removing the water-soluble salts from the crude oil. A crude oil desalter is a device used in petroleum refineries to remove inorganic salts, water and sediment from the incoming petroleum crude oil feedstock before it is refined. This article focuses on the use of electrostatic desalters to produce a dehydrated, desalted crude oil with a low sediment content.
In desalting systems, before sending a stream of crude oil to the distillation process, it is put in contact with water by means of a mixing system that promotes close
The first oil refinery unit is crude oil desalting. The desalter removes salt, water and other contaminants from crude oil prior to distillation in an atmospheric tower. The fractions recovered from the atmospheric distillation tower include naphtha, kerosene, diesel and bottoms liquid called atmospheric resid. Clean dilution or wash water is injected into the crude oil feed to the desalter through a mixing device to dilute the brine to a level where the target salt content can be achieved by the downstream Dehydration Unit. In difficult applications this wash water can be recovered and recycled in a 2 stage dehydration and desalting process. Desalting involves mixing heated. crude oil with washing water, using a mixing valve or static mixers to ensure a proper contact. between the crude oil and the water, and then passing it to a separating vessel, where a proper. separation between the aqueous and organic phases is achieved. Understanding the Process of Crude Oil Desalting. Crude oil contains many contaminants, such as inorganic salts, sand, drilling mud, suspended solids, polymer, corrosion byproducts, and more. These contaminants need to be removed to refine the oil into a finished product. The process is called separation. The two most typical methods of crude-oil desalting, chemical and electrostatic separation, use hot water as the extraction agent. In chemical desalting, water and chemical surfactant (demulsifiers) are added to the crude, heated so that salts and other impurities dissolve into the water or attach to the water,

Desalter performance can be In the desalting process, crude oil is contacted with hot water to remove impurities such as chloride salts and par- ticulate matter before continuing through. It is critical that these undesirable reservoir residues are extracted from crude oil to avoid costly corrosion and fouling of downstream equipment. Over time‚ these
