Although all XRF techniques are capable of only total elemental analysis, with some sample preparation, Clora, Clora with Accu-flow, Clora 2XP, and Sindie + Cl Organic chlorides do not naturally occur in crude, however inorganic form of salts as well as residual organic chlorides from various natural sources as well as Crude Oil; Atmospheric Residue; Organic Chlorides; Extraction; GC/MS The mass spectrometer was operated with an electron ionization (EI) source at 70 eV 23 Jan 2020 Organic chloride found in the oil varied between 70 and 120 ppm (parts per million), the Tests of crude oil in the Kazakh pipeline system carried out this week showed organic Source: Reuters, Hydrocarbon Processing. (1) source of organochlorine compound and form in the crude oil Chloride crude oil is distilled, cut each narrow fraction, the content of organic chloride of each 25 Apr 2019 Organic chlorides are rarely present in crude oil but can be found when system and is trying to investigate the exact source of the problem.
6 Feb 2018 Approach of Handling Crude Oil and Sources of Wastes. The preliminary as equivalent sodium chloride, per thousand barrels of oil). Salt in. 4 Jun 2019 Among them, the Mississippi-Valley type deposits and related oil fields often with disseminated liquid petroleum (crude oil) and other organic and transported by oxidized basinal hydrothermal fluids as chloride complexes. 30 Dec 2017 comes from various crude oil extraction additives, which can reduce chlorine atom can be chosen to react with organic chloride species so as 23 May 2019 Transneft PJSC, Russia's state crude oil pipeline operator, said for supplying oil contaminated with organic chlorides to local refineries.
As a result, refineries typically do not accept crude oil that contains more than 5 parts per million (μg/g) of organic chloride. Organic chlorides are determined through potentiometric titration per Standard Method ASTM D4929. This method utilizes a sodium biphenyl reduction of the organic chlorides to yield inorganic chlorides. The chlorides are then extracted from the petroleum sample into an aqueous phase and titrated with silver nitrate. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery. chlorides that can be found in crude oil. Obviously, these chlorides can also come from the formation water which is entrained with the oil. In crude oil, chlorides can exist in two forms, organic chloro-hydrocarbon and inorganic chloride (e.g. sodium chloride). The removal of the inorganic chlorides is not that difficult to main source of organochlorine in crude oil is the chlorinated chemical additives added to the oil field, so the most fundamental measure for reducing organic chlorides in crude oil is to eliminate use of various kinds of chlorine-containing oilfield chemicals, Sources Of Organic Chlorides • Generally NOT naturally occurring • Used to be used extensively in the oil field - Wax dissolver • Generally banned on environmental grounds • Primary sources now believed to be contamination • Unscrupulous dumping into transportation pipelines • Contamination of tankers and barges The organic chloride content of the contaminated crude oils was found to have ranged from approximately 3 to 3,000 ppm (rag/L). Organic chlorides in crude oil are known to cause severe corrosion in crude tower overhead systems. Therefore, most refineries allow no more than 1 ppm (mg/L) organic chlorides in the crude charge. Total chloride content is lower in the distillates of 200°-350°C, and is the lowest in the distillates of 150°-200°C. Chloro-chemical assistant adding in the oil recovery process is the main source
Crude Unit Atmospheric Distillation Overheads. – Vacuum Unit Typified by no “ apparent” increase in salt in desalted Crude Sources Of Organic Chlorides.
