A desalter's purpose is to remove crude oil contaminants that will have harmful effects in downstream equipment and process units. The more desalting is optimised, the more contaminants will be removed. As mentioned previously, feeding the desalter a consistent diet will help in the process as well as keeping the temperature high.

Desalting is a water-washing operation performed initially at the production field and thereafter at the refinery site for additional crude oil cleanup. Salt and water content specifications are even more rigid because of their negative effect in downstream processes due to corrosion, and catalyst deactivation. An optimum formulation concept is presented to …

The term desalter may also refer to a water desalination facility used to treat brackish water from agricultural runoff. This may be done either to produce potable water for human or animal consumption, or to reduce the salinity of river water prior to its crossing an international border, usually to comply with the terms of a treaty.

The oil from the three-phase separator is pumped to the desalter using desalter feed Pumps. Wash water is pumped through a Wash Water Pre-Heater and then mixed with the Crude Oil using a mixing valve or static mixer. The brine from desalter is mixed with the produced water which is coming from three phase separator for treatment and disposal.

Desalter Urdu Meaning - Find the correct meaning of Desalter in Urdu, it is important to understand the word properly when we translate it from English to Urdu. There are always several meanings of each word in Urdu, the correct meaning of Desalter in Urdu is نمک رُبا, and in roman we write it Namak Rubaa.

The wet crude oil is fed into the dehydrators/desalters through Howe Baker's specially designed distribution headers and spreaders which ensure even flow through the unit such that no section of the unit is over or under-loaded and the longest retention time for the crude oil inside the treater with no recirculation inside the treater.

To conclude on this question, it is important to keep in mind that a desalter is designed to perform for a specific range of crude feed and operational conditions. Hence, any changes in those conditions need to be addressed in coordination with the desalter supplier which can support the end user to tune its unit and assess specifically the ...

Desalter sizing is strongly influenced by viscosity which is dependent on the operating temperature. A desalter feed temperature of at least 70˚C should be allowed in the design of very viscous oils. Higher temperatures will decrease the size of desalter vessels, but is a trade-off of vessel cost versus heating costs. Piping Supports: Types ...

The highest growth of the two stage desalter segment is ascribed to the provision of the high efficiency of two stage desalter and also rising usage of heavy petroleum in refineries around the world. In terms of end-use, the market is categorized into FCC feed desalting, heavy crude desalting, distillate treating, others.

Shortly after being installed, the desalter feed rates had to be reduced due to a local operational problem. Clora Online reported a climb in chlorides exiting the desalter, confirmed by the Nalco 3DT COS on the overhead as seen in Figure 7. This climb was attributed to a decreased mix valve dP, reducing mixing efficiency and leading to poor ...

The crude feed is then mixed back together and passed through the desalter unit. Effluent leaving the desalter is heated up further in heat exchangers 9, 7, 8, 5, and 4 by the product streams Heavy Naphtha, Kerosene, Reflux, Gas Oil, and Fuel Oil, respectively.

that has operated a SHE in desalter service since 2008. The process of cooling the effluent water has caused fouling headaches in refineries for years, as was the case with the major refinery covered in this article. Due to continuous, costly fouling and plug-ging problems, it was necessary to shut down the S&Ts cooling the desalter efflu-

Desalter sizing is strongly influenced by viscosity which is dependent on the operating temperature. A Desalter feed temperature of at least 70C should be allowed in the design These design guideline are believed to be as accurate as possible, but are very general and not for specific design cases.

Desalting of Crude oil means the removal of the dissolved salt in the crude oil and increasing the grade of the crude oil. Crude oil dehydration is the process of removing the water present in crude oil to meet the purchaser's limit. Since salt is dissolved in the water so that dissolved salt is also removed in the process.

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.

This can be performed by a desalter unit. 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.

Desalter is identical to Dehydrator, but the task of the Desalter is the removal of water soluble salts (in water). Before entering the Desalter, the partially treated oil is mixed with wash water (dilution water) through the mixing device to dilute the residual saline formation water contained in the crude oil. Inside the Desalter, water drops ...

Efficiency is low in many desalter units, meaning that the crude leaving the desalter stage contains salt and impurities that cause corrosion and fouling issues in downstream process equipment. Whether the solution lies in optimizing the temperature in the desalter itself, or adding a second desalter stage, it will require a process design with ...

The condensate stabilization process can be configured to produce LPG from the stabilizer column. To meet the ethane content in the LPG product, a feed liquid stripper is required upstream of the stabilizer. This stripper is designed to remove all the acid gases and lighter components such that the LPG product from the downstream stabilizer would meet the H 2 S …
