Brief description of the process and production chart:
The 1-botnet-1 petrochemical unit with a capacity of 100,000 tons per year is the largest botanical unit in the country. In addition to providing the needs of downstream units, the company has the capability to meet the needs of other country's polyolefin companies, as well as the major part of the production, for export to the consuming countries. Has been considered.
Production of butane -1 is based on the dimerization of two molecules of ethylene in the liquid phase. This reaction is carried out in the presence of LC catalyst and TEA coctalist in two series of reactor sets that are in parallel operating mode. This reaction is intense and the heat of reaction is eliminated by means of circulating loops with Chilly water (prepared by the propylene refrigeration system).
The stream contains boot-1 and + C6 from the bottom of the reactor and is sent to the evaporation portion after injection of amine (reaction stopping agent). After separating the lighter compounds in the drag of flash and then separating the catalysts and amines used in the TFE, the vapor flow of the product, including boot-1, + C6, and unreacted ethylene, is sent to the distillation section. . In this section, which contains two towers, the high flux of the first tower has not reacted with ethylene, which is returned as a return flow to the reactors; and its flow is sent to the second tower, where the botanum -1 is used as the product of the tower above and + C6 is isolated as a product of the bottom of the tower.
