The processing of oil fractions or natural gas produces a significant amount of liquid products of pyrolysis (LPP) or cracking of hydrocarbons. Due to the increase in the capacity of pyrolysis plants, a large number of LPPs are formed, the qualified use of which is a necessary condition for ensuring the profitability and waste-freeness of ethylene. The yield of LPP, depending on the raw material and the mode of the pyrolysis process, is 20 ... 40%. The use of LPP for the production of petroleum resins can significantly improve the technical and economic performance of ethylene plants and reduce the cost of ethylene by 20 ... 30%. LPP fractions and their combinations are mainly used to obtain NPS.
