Integrated enhanced solvent deasphalting and caulking process to produce petroleum coke green

摘要

An integrated process for producing deasphalted oil, high quality oil green coke and liquid coger products is provided. Improved solvent deasphalting processes are used to treat feedstock to reduce levels of asphaltenes, N, S and metal contaminants and to produce deasphalted oils with reduced contaminants. The caulking process is integrated to produce liquid and gas caulking unit products, and petroleum green coke.
