Isomerization enhances gasoline research octane number (RON) by converting straight-chain paraffin into a branch chain and simultaneously decreasing the benzene content through benzene...

The selection of optimal process flow diagram (PFD) of light naphtha isomerization is an important research and practice task which can be solved more efficiently with a help of mathematical modelling method.

The operation of the Butamer Isomerization Unit is similar to the pentane isomerization unit. In the isomerization process, the butane feed is mixed with the butane recycle and enters the deisobutanizer. Any propane present is sent overhead to be used as a fuel gas.

isomerization process which converts normal paraffins into their isomers. This results in a significant octane increase as normal pentane (nC 5) has an octane number of 61.7, while its isomer, isopentane (iC 5), has an octane number of 92.3. In a single-pass isomerization, the octane number of LSR gasoline can be increased from 70 to 84.

Isomerization Model • Goal – To create a model that determines the products of the isomerization unit • Model inputs – Temperature (range depends on catalyst used) – Mass flow rate – H 2/HC ratio (typical values 0.1-4) – Feed stream concentrations • Model outputs – …

Isomerization is the conversion of low octane straight chain compounds to their higher octane branched isomers. The purpose of this process is to saturate benzene and to isomerise normal paraffins to improve the research and motor octane number of the light naphtha feed (predominantly C5/C6) before blending into the gasoline pool.

Isomerization is typically used for normal butane conversion to isobutane or straight run naphtha isomerization to substantially improve octane. Here we will focus on naphtha isomerization. This process isomerizes straight run naphtha, which has a low octane value and catalytically isomerizes it to create a much higher octane product.

Isomerization is used for the conversion of n-paraffin to iso paraffin to provide good quality gasoline and to provide additional feed stock for alkylation units. Isomerization process complements catalytic reforming process (Catalytic reforming is used to convert hydrocarbons to aromatics which have high octane rating) in

goal of the Naphtha hydro-treating (NHT) unit is to produce clean and refined feed for the supply of Octane and Isomerization units. The feeds of these units should have the lowest amount of pollutants such as sulphur, nitrogen, water, halogens, diolefins, olefins, a.

The Penex Deisohexanizer (DIH) isomerization is a process operated using the catalytic reaction of n- pentanes, n-hexanes, and mixtures thereof to produce isomerate hydrocarbons. The reactions take place in a hydrocatalytic fixed bed reactor to promote conversion and minimize hydrocracking [1].
