Magnesium chloride is a white, crystalline compound composed of magnesium and chlorine. It forms hygroscopic flakes or granules with a bitter taste. It is highly soluble in water and commonly used as a de-icer, dust suppressant, and in various industrial and pharmaceutical applications.
In the energy sector, magnesium chloride finds multiple applications. It is commonly used as a drilling fluid additive to control the viscosity and density of drilling mud, aiding in wellbore stability and lubrication during drilling operations. Magnesium chloride brines are also employed in well completion and workover fluids to prevent clay swelling and formation damage.Moreover, magnesium chloride is utilized as a catalyst in various petroleum refining processes, such as catalytic cracking and hydrocracking. It helps facilitate the conversion of heavy hydrocarbons into more valuable products like gasoline, diesel, and jet fuel.Additionally, magnesium chloride is used in natural gas production as a hydrate inhibitor. It prevents the formation of gas hydrates, which can obstruct pipelines and equipment. By adding magnesium chloride to the gas stream, the risk of hydrate formation is mitigated, ensuring smooth and uninterrupted gas flow.
Magnesium chloride is extensively used in water treatment processes for various purposes. It acts as a coagulant, aiding in the removal of suspended particles and colloidal matter, resulting in clearer and higher-quality water. Additionally, it serves as a softening agent by reducing water hardness through the formation of insoluble precipitates. Magnesium chloride is also employed for pH adjustment, corrosion control, and odor/taste control in water. It helps stabilize pH levels, inhibits corrosion in pipelines and equipment, and neutralizes unpleasant odors and tastes. Furthermore, it finds application in anti-icing and de-icing operations, preventing ice formation on roads and walkways. Overall, magnesium chloride contributes significantly to improving water quality and usability in water treatment processes.
