PROCESS AND SYSTEM FOR OBTAINING CRUDE OIL PRODUCTS

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 apparatus (100) configured to carry out the method.

1. Method for obtaining crude oil products wherein a gaseous stream (d) is formed from a crude oil stream (b) by evaporation and the gaseous stream (d) is at least partly subjected to a steam cracking process (1), wherein, in the steam cracking process (1), a cracked gas stream (e) is produced which is at least partly quenched with a liquid hydrocarbon stream (f), with formation of a quenching effluent (g), characterised in that a fraction (f) that remains liquid during the evaporation (2) of the crude oil stream (b) is at least partly used to form the hydrocarbon stream (f) using for quenching, wherein 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 is obtained by quenching with the liquid hydrocarbon stream (f) at a temperature in the range from 0 to 250° C.
