FIELD: petroleum processing. ^ SUBSTANCE: invention relates to technology of processing heavy petroleum residues, in particular to coking process, which can be used in delayed coking plants. Processing of sulfur-containing raw material in delayed coking plants comprises preheating raw material and treating it with supplied hydrogen, said raw material being heavy petroleum residues or petrochemical by-products. Coking process is carried out in one step in presence of hydrogen supplied in quality 10 to 200 m3 per 1 m3 raw material. ^ EFFECT: increased yield of liquid products, reduced sulfur level in products, and reduced material and power consumption. ^ 2 cl, 2 tbl |
