Reasons for Using Calcium / Iron Removers

Cestoil’s calcium/iron remover is a type of organometallic compound used to remove calcium in crude oil. It is often added to the electric desalination unit along with a demulsifier to remove most of the metallic calcium and its compounds.

Calcium in crude oil takes two forms: inorganic salts and organic salts. Inorganic salts are soluble in water so they can be separated by dehydration. Organic salts, such as naphthenate and phenate, are oil-soluble compounds which will form a layer of oil and water emulsion in the electric desalination unit. This layer of emulsion can cause equipment fouling and catalyst contamination, so a calcium/iron remover is required to solve the problem.

Our calcium/ iron remover CC827494 is only water soluble, which can minimize the acid content in the crude. Further, its decalcified chelate components are soluble in water and can be separated easily.
