Normal paraffins or normal alkanes are simply written as n-paraffins or n-alkanes, and they are open, straight-chain saturated hydrocarbons. Proceedings of the 4th International Gas Processing Symposium: A volume in Advances in Gas Processing. 9% per annum during 2019–24. Olefins are alkenes, and paraffins are alkanes. The olefins are converted into hydrogen saturated compounds of the same carbon number and structure. Chlorinated paraffin/olefin products generally increase in density and viscosity as more chlorine. Natural gas purification and olefin/paraffin separation using cross-linkable dual-layer hollow fiber membranes comprising Β-Cyclodextrin. paraffin [par´ah-fin] 1. Application of azeotropic distillation to the separation of olefins and paraffins. Normal paraffins (n-paraffins or n-alkanes) are unbranched straight-chain molecules. All olefin and paraffin SBFs and diesel oil base fluids biodegrade in the presence of oxygen (aerobic). Four packed silica columns in series are used to isolate the aromatics and provide ring number distribution. Rezel dehydrogenation catalyst offers superior selectivity and on-stream efficiency.
