- W2098182459 abstract "Existing technologies of pygas processing are considered. Styrene extraction from BTX cut by means of extractive distillation process is suggested for JSC Salavatnefteorgsintez. Main benefits of this modernization are described. The profitability increasing policy is constantly carried out at JSC Salavatnefteorgsintez. For manufacturing divisions it means new state-of-the-art units construction and modernization of existing plants that improves their products' competitiveness. One of prospective investment projects at the company is the pyrolysis unit EP- 700. Thus total ethylene capacity will be increased from 300 kta that current EP-300 unit supplies up to 1 Mta. Increasing of capacity will make reasonable the implementation of many technologies that increase total efficiency of pyrolysis plants and reduce the cost of the main product. One of the most prospective areas of such technologies is liquid pyrolysis products processing technology improvement. Liquid are called all the pyrolysis products that are in liquid aggregative state at normal conditions. Usually they are fractionated on two cuts - pyrolysis gasoline (С 5 - С 8 , pygas) and heavy fuel oil (C 9 and higher). Pygas consist mostly of aromatic (benzene and its homologes), olefinic and naphthenic hydrocarbons; fuel oil - of high- molecular compounds of aromatic, naphthenic and naphtheno-aromatic series. Heavy oil is generally used as a fuel (moderate calorific value, low sulfur content), in certain cases it can be used as a feed for production of coke, carbon black, petroleum polymer gums, pitches etc. Pygas is the most valuable by-product of pyrolysis process, so the optimization of its processing is of particular importance. Let's consider two main ways of pyrolysis gasoline prosessing: fuel and petrochemical." @default.
