| titleOfInvention | METHOD FOR ISOMERIZING LIGHT GASOLINE FRACTIONS |
| abstract | 1. The method of isomerization of light gasoline fractions, consisting of isomerization of gasoline fractions followed by separation of the reaction mixture in three fractionation apparatuses with the allocation of five streams: a gas stream of recirculation, enriched with hydrogen, a mixture of light gases and butane, a mixture of normal pentane, methylbutane and dimethylbutane, a mixture of methylpentane and normal hexane and a stream of heavy hydrocarbons, straight-run and secondary gasoline fractions of 40 ÷ 75 ... 85 ° C are used as raw materials, preparation before isomerization is carried out in addition flax distillation column and the supply of straight-run gasoline fraction 40 ÷ 75 ... 85 ° C for isomerization is carried out separately from the gasoline fraction 40 ÷ 75 ... 85 ° C of the secondary oil refining processes, and the gasoline fraction 40 ÷ 75 ... 85 ° C of the secondary processes is fed into the second or third distillation column. 2. The method of isomerization of light gasoline fractions according to claim 1, characterized in that gasoline fractions 40 ÷ 75 ... 85 ° C obtained from catalytic cracking, catalytic reforming, visbreaking and other technological units of fuel and gas-catalytic applications are used as a gasoline fraction of secondary processes .3. The method of isomerization of light gasoline fractions according to any one of claims 1 and 2, characterized in that the preparation of gasoline fractions from several secondary processes is carried out with their preliminary mixing. The isomerization method of light gasoline fractions according to claim 1, characterized in that the gasoline fraction of the secondary processes having a high content of butanes is sent to the second distillation column.
