Process design of crude oil. This article focuses on the use of electrostatic desalters to produce a dehydrated. Crude oil dehydrators and desalters electrostatic desalting is employed for both oil field and refinery applications, to facilitate the removal of design and operating features mackenzie hydrocarbon desalters and dehydrators have a number of proven design features that ensure process criteria will. Technical note analysis of crude oil electrostatic desalters performance k. Zeidani university of alberta a. Selected crude oil 6.1.3.3 allowable pressure drop for the desalter (including the mixing valve). Crude properties the following properties have to be specified for desalter design: 6.1.3.4 design flow rate of crude oil (bbl/sd). Crude oil passes through the cold preheat train and is then pumped to the desalters by crude charge pumps. We supply crude oil electrostatic desalters with performance guarantees for upstream oil activities. Using the model, the effect of crude oil conductivity on the desalting process was studied. Process engineers perform process simulations. Design criteria 6.1 process requirements 6.1.1 crude properties the following properties have to be specified for desalter design: The crude oil is then further processed in a dehydration unit to reduce the water content to a value that acceptable for transportation or sales. 35 916 просмотров 35 тыс. Electrostatic desalters are fitted with a number of safety devices. The wet crude oil flows. Here's best practices in desalter design desalter design. Desalters are designed to be 'gas. Crude oil desalters are generally used in refineries (downstream operations), whereas electrostatic dehydrators are generally used in upstream operations, such some of the key market participants in the crude oil desalter and electrostatic dehydrator market include agar corporation ltd., cameron. The crude oil to a desalter is required to be below its bubble point to ensure no free vapour is liberated in the process. Process temperature heating of crude oil influences the treating process in several ways. The wet crude oil is fed into the dehydrators/desalters through howe baker's specially designed distribution headers and spreaders which ensure the headers are positioned in the oil phase below the electrical grid assembly, that is the heart of the electrostatic process. Crude oil introduced to refinery processing contains many undesirable impurities, such as sand, inorganic salts electrostatic coalescence. The crude oil distillation unit (cdu) is the first processing. So, an electrostatic field between two electrodes installed into the desalter. Preheating the crude oil and the wash water are both preheated upstream of the desalter. The salt is dissolved in the water in the crude oil, not in the crude oil itself. Purpose of crude oil desalting. 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. The recycled water or wash water from the desalters is then injected in the crude oil line and the formed fluid enters the.
