How is organic chloride removed from crude oil?

At present, the methods for removing organic chloride in crude oil mainly include catalytic hydrodechlorination, dechlorination using a chlorine transfer agent, and dechlorination by adsorption methods.

What is a chloride test in oil and gas?

1. n. [Drilling Fluids] A titration procedure standardized by the API to quantitatively determine Cl– (chloride ion) concentration by using silver nitrate as titrant with potassium chromate as the endpoint indicator.

What is organic chlorides in crude oil?

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.

Are chlorides organic?

What is added to the mud in a chloride test and why?

The procedure for measuring chlorides is as follows: Add five drops Phenolphthalein indicator solution and if the indicator turns pink then add 0.02N Sulfuric or Nitric Acid (drop by drop), stirring the sample with a glass stirring rod until the pink color disappears.

Where do organic chlorides come from?

Is chloride organic or inorganic?

An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications.

What causes organic chlorides in crude oil?

How do you identify chlorides?

The test for chloride ions described here is based on precipitation of an insoluble chloride salt. When a few drops of a silver nitrate solution are added to a slightly acidic aqueous solution that contains chloride ions, a white precipitate of silver chloride will form.

What is the organic chloride?

An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Organic chlorides are organic molecules with a C-Cl bond, for example chloroform (CH3-Cl) or vinyl chloride(C2H3Cl). Organic chlorides can be used in production of: PVC. Pesticides.

Is chloride an organic chemical?

The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion.
