Includes all processes that convert some of the compounds produced by the treatment and fractionation of natural gas or the refinement of oil into other compounds (mainly olefins and aromatics), commonly used as a base for the production of textiles, plastics, synthetic rubbers and resins, therefore for all the objects we use in daily life. The main process in which our internals are found is:
The primary sources of benzene, toluene and xylenes (BTX) are refinery processes (especially reforming and catalytic cracking), pyrolysis of petrol in Steam Cracking and the liquefaction of coal.
Xylenes are a mixture of aromatics consisting of three isomers (ortho, meta and para xylene). Para-xylene is the most important of the three isomers as it is used for producing terephthalic acid, a base compound in manufacturing polyester materials. Due to the narrow range of the boiling points of xylene isomers, separation by distillation is particularly difficult. Currently, continuous liquid phase adsorption processes are used in the industry to recover para-xylene from mixed xylenes.
Costacurta manufactures adsorption chamber internals according to the specifications of the leading process licensors in the aromatics processing field.
