METHOD FOR ENRICHMENT OF HEAVY CHARGES BY DESASPHALTATION AND HYDROCRACKING IN BOILING LAYER |
摘要 |
FIELD: oil and gas industry. ^ SUBSTANCE: invention may be used for processing of oil fractions. Hydrocarbon charge is supplied along line 1 into section 2 for desasphaltation in presence of dissolvent. Asphalt fraction and part of dissolvent pumped into section 2, are extracted via line 4 and supplied to section 5 for separation of dissolvent and asphalt. Asphalt is extracted via line 6. Dissolvent is extracted via line 7 and repeatedly pumped into section 2 via lines 8, 1 and 3. Desasphalted fraction and part of dissolvent forced in section 2 are extracted via line 9 and sent to section 10 for separation of dissolvent and desasphalted fraction. Dissolvent is extracted via line 8 and repeatedly forced in section 2 along lines 8, 1 and 3. ^ EFFECT: high yield of benzene, kerosene and diesel fuel from distillation remainder at atmospheric pressure or from vacuum distillation of heavy oil. ^ 11 cl, 2 dwg |
