How do you test for organic chloride?
Testing for organic chlorides is completed on the naphtha fraction of crude where distillation is performed to 204°C (400°F). ASTM D4929 is the preferred test method set forward by industry standards for the determination of organic chloride in crude oils.
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 Microcoulometry?
Microcoulometry is an absolute detection technique. All (organic) chloride components are converted to hydrochloric acid (HCl). The XPLORER-TX achieves a 100% recovery. Therefore, calibration of the XPLORER-TX can be done but is not even necessary.
What is organic and inorganic chloride?
An organic chloride is a compound containing at least one “covalently bonded” atom of chlorine. Inorganic chlorides are those compounds where one or more chlorine atoms are directly connected with metals like sodium, calcium, aluminum, iron copper, magnesium, lithium and many more.
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 added to the mud in a chloride test and why?
The chloride content in the drilling fluid can be maintained by adding salts such as potassium chloride (KCl) and sodium chloride (NaCl). If potassium chloride (KCl) is used, it is imperative to have sufficient potassium ions to react with the clay content from the formation.
Are chlorides organic?
Organic chlorides are chloride-containing organic compounds that are generally not naturally occurring. They are extensively used in the oil field as a wax dissolver. Organic chlorides are generally not present in crude oils and are usually derived from cleaning operations at production sites/pipelines or tanks.
What is total sulfur?
Total Sulfur (TS) stands for the sum parameter of all organic and inorganic sulfur compounds. Trace levels (0.02 – 10.000 mg/kg or ppm by weight) of Total Sulfur are measured with an elemental combustion analyzer according to UV-Fluorescence detection technique or Microcoulometric detection technique.
What is meant by coulometry?
Coulometry determines the amount of matter transformed during an electrolysis reaction by measuring the amount of electricity (in coulombs) consumed or produced. Coulometry is a group of techniques in analytical chemistry. It is named after Charles-Augustin de Coulomb.
What is inorganic chloride?
Inorganic chlorides are those compounds where one or more chlorine atoms are directly connected with metals like sodium, calcium, aluminum, iron copper, magnesium, lithium and many more.
