Propene, also known as propylene or methyl ethylene, is an unsaturated organic compound having the chemical formula . It has one double bond, and is the second simplest member of the alkene class of hydrocarbons. It is a colorless gas with a faint petroleum-like odor. Propene is a byproduct of oil refining and natural gas processing. During oil refining, ethylene, propene, and other compounds are produced as a result of cracking larger hydrocarbons. A major source of propene is naphtha cracking intended to produce ethylene, but it also results from refinery cracking producing other products. Propene can be separated by fractional distillation from hydrocarbon mixtures obtained from cracking and other refining processes; refinery-grade propene is about 50 to 70%.
SEMA Gases is a manufacturer of span gases in disposable cylinder cans from the Netherlands, established from the want to create a label which is applicable for all brands of gas detection equipment. The products of SEMA Gases are used for calibration of portable gas detection instruments and calibration of fixed gas detection systems. SEMA Gases produces single gases (flammable gases, oxygen, toxic gases) and gas mixtures (2, 3, 4 or 5 gas mixtures) in various cylinder size up to 110 ltr.
