摘要:
A method for obtaining crude oil products is proposed in which a gaseous stream (d) is formed from a crude oil stream (b) by evaporation (2) and the gaseous stream (d) is at least partially subjected to a steam cracking process (1), a cracked gas stream (e) being produced in the steam cracking process (1) which is at least partially quenched with a liquid hydrocarbon stream (f), thereby forming a quenching effluent (g). It is provided that a fraction (f) of the crude oil stream (b) that remains liquid during the evaporation (2) of the crude oil stream (b) is used at least partly to form the liquid hydrocarbon stream (f) used for the quenching. The liquid hydrocarbon stream used for the quenching is low in or free from components that have been separated from the quenching effluent (g) or a stream formed from the quenching effluent (g) and the quenching effluent (g) is obtained by quenching with the liquid hydrocarbon stream (f) at a temperature in the range from 0 to 250° C. The invention also relates to an
