METHOD OF PREPARATION OF HYDROCARBON RAW MATERIAL FOR TRANSPORTATION AND PRIMARY OIL REFINING Russian patent published in 2002 - IPC

FIELD: transportation and refining of oil products. SUBSTANCE: invention can be used at transportation of gas condensate along pipelines or in railway tanks at low ambient temperatures and in process of primary oil refining. According to proposed method, hydrocarbon raw materials are prepared for transportation along pipelines or in railway tanks at low ambient temperature by adding materials with other physical and chemical properties into hydrocarbon raw material. Gas condensate with tar and asphaltene content from 0.51 to 0.97 mass % and paraffin wax content from 0.36 to 0.91 mass % is used as base hydrocarbon raw material. Fuel oil with paraffin wax content from 1.9 to 4.6 mass % is used as addition. Fuel oil in amount from 5 to 30% of gas condensate volume is added. EFFECT: reduced energy consumption at low ambient temperatures without considerable degradation of product quality at increased yield of light fuel fractions in process of primary oil refining.
