Glycol dehydration. Glycol dehydration is a liquid desiccant system for the removal of water from natural gas and natural gas liquids (NGL). It is the most common and economical means of water removal from these streams. [1] Glycols typically seen in industry include triethylene glycol (TEG), diethylene glycol (DEG), ethylene glycol (MEG), and ...
Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses. [3] Similar to other glycol ethers, it is used as a carrier/solvent in printing/writing inks and paints /coatings. It also finds use as an industrial and commercial paint stripper.
Amine gas treating. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases. [ 1 ][ 2 ][ 3 ] It is a common unit process ...
Paint remover is applied to an aircraft's landing gear during an inspection looking for cracks in the aluminum. Paint stripper or paint remover is a chemical product designed to remove paint, finishes, and coatings, while also cleaning the underlying surface. Chemical paint removers are advantageous because they act on any kind of geometry and ...
Rust converter. Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides (rust) into a protective chemical barrier. These compounds interact with iron oxides, especially iron (III) oxide, converting them into an adherent black layer (black oxide) that is more ...
Stripping (chemistry) Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream. [1] In industrial applications the liquid and vapor streams can have co-current or countercurrent flows. Stripping is usually carried out in either a packed or trayed column.
Levulinic acid esters from the same source would have the potential to replace DCM in paint cleaners and strippers. Used cooking oils can be used to produce FAMEs . [ 17 ] Glycerol , obtained as a byproduct of the synthesis of these, can in turn be used to produce various solvents such as 2,2-dimethyl-1,3-dioxolane-4-methanol, usable as a ...
Diethylene glycol (DEG) is an organic compound with the formula (HOCH 2 CH 2) 2 O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. [ 3 ]
