What is the use of VCM?

Vinyl Chloride Monomer (VCM) is a colorless, flammable gas at room temperature. Its chemical formula is C2H3Cl. It is primarily used to manufacture polyvinyl chloride (PVC), a very stable, non-flammable, lightweight and durable plastic. PVC is used in a variety of applications.

Who makes vinyl chloride monomer?

AGC Chemicals
Product summary. AGC Chemicals has manufacturing plants in Japan and Indonesia, and manufactures and sells vinyl chloride monomers (VCM).

Where is vinyl chloride made?

Vinyl chloride monomer (VCM) is the key chemical precursor to PVC. It is produced commercially by combining a hydrocarbon feedstock, namely ethylene, obtained by cracking natural gas or petroleum, with elemental chlorine. Chlorine is derived from brine—a solution of common salt and water.

How is VCM produced?

The five main processes used in the production of vinyl chloride monomer (VCM) are: (1) direct chlorination of ethylene to form EDC, (2) oxychlorination of ethylene to form from recycled HCl and oxygen, (3) purification of EDC, (4) thermal cracking of EDC to form VCM and HCl, and (5) the purification of VCM.

What is meaning of VCM?

Value chain management (VCM) is a strategic business analysis tool used for the seamless integration and collaboration of value chain components and resources.

What does VCM smell like?

VCM is a colourless flammable gas at normal ambi- ent temperatures, and is unstable at high tempera- tures. It has a mild, sweet odour. Most people begin to smell VCM in the air at ~7.8 mg/m3.

Why is vinyl chloride hazardous?

Vinyl chloride can irritate the eyes, mucous membranes, and respiratory tract. Escaping compressed gas or liquid can cause frostbite or irritation of the skin and eyes. Chronic exposure can cause permanent liver injury and liver cancer, neurologic or behavioral symptoms, and changes to the skin and bones of the hand.

What is VCM Muzzler?

Variable Cylinder Management (VCM) is a technology introduced by Honda on its V6 engines to improve EPA fuel efficiency numbers. It involves using the PCM to shut down cylinders at cruising conditions. You plug it inline with the engine coolant temperature sensor and adjust it based on your driving style and location.

What is PCM sheet?

Pre painted metal sheet, short for PCM Pre painted metal sheet is also a kind of color coated metal sheet, coated with high polymer paint on. the top surface. Apart from excellent processability and corrosion-resistance, it not only improves the. appearance of product,but also could satisfy some special functions.

Is VCM a liquid?

VCM is often stored as a liquid under pressure. The liquid evaporates readily at ambient temperatures. At high concentrations, it has a sweet odor typical of chlorinated hydrocarbons.

Is vinyl chloride harmful to human health?

Vinyl chloride exposure is associated with an increased risk of a rare form of liver cancer (hepatic angiosarcoma), as well as brain and lung cancers, lymphoma, and leukemia.

Is vinyl toxic to humans?

Polyvinyl chloride (PVC or vinyl) is the most toxic plastic for our health and the environment. During its lifecycle — from production to use to disposal — vinyl releases some of the most toxic chemicals on the planet that have been linked to cancer, birth defects and other serious chronic diseases.

Why choose VCM?

Why do VCM and butadiene require special attention during cargo operations?

Because of their specific characteristics, VCM and butadiene require special attention during cargo operations. This section highlights characteristics and procedures of the two cargoes which differ from the procedures included in the other sections of these operating instructions. Risk of carrying VINYL CHLORIDE MONOMER (VCM)

What happens to VCM when piping is disconnected from the air?

Those portions of cargo lines which will be open to the atmosphere after piping is disconnected are free of VCM liquid and that the VCM vapour concentration in the area of the cargo piping disconnect points is not greater than 5 ppm.

Can VCM be discharged with a booster pump?

Due to its high density VCM must not be discharged with deepwell pumps running in series with booster pumps. If, during stripping, it becomes necessary to increase pressure above the liquid residues by introducing gas from another tank, the pressure difference between the two tanks is to be approximately 2.5 bar.
