Abstract
Objective The aim is to realize the high-value utilization of CNOOC cycloalkyl vacuum residue.Methods Using the cycloalkyl vacuum residue of CNOOC as raw material,the product distribution and economic benefits of the direct coking process and solvent deasphalting-high pressure hydrogenation-coking combined process were compared.The combined process first used propane as the solvent to perform solvent deasphalting on vacuum residue,which was divided into light deasphalted oil and deoiled asphalt.The light deasphalted oil used a three-stage high-pressure hydrogenation process to produce 150BS bright oil products,and the deoiled asphalt products used a coking process to produce petroleum coke and other petroleum fractions.Results Compared to the direct coking process,the total yield of the liquid product using the combined process was increased by 2.67 percentage points,and the brief economic calculation revealed that the combined process resulted in greater profitability.Conclusions After adopting the combined process,the high-value utilization of vacuum residue can be achieved,and the total yield of liquid products can be increased.关键词
