Latest Patents

One of Keng H Chung's latest patents is titled "Integrated process for upgrading heavy oil." This invention provides an integrated process for processing heavy oil, wherein solvent deasphalting is carried out for heavy oil material. The de-oiled asphalt phase is mixed with a dispersing agent and then enters a thermal cracking reactor to undergo thermal cracking reactions. Upgraded oil can be obtained through the mixture of the de-asphalted oil and thermal cracking oil separated from thermal cracking reaction products. The solvent and heavy gas oil, which are separated from the thermal cracking reaction products, are respectively recycled back to the solvent deasphalting process as solvent and as mixed feed to remove asphaltene. This integrated process addresses the challenges of separating solvent from asphalt with a high softening point and facilitates the transportation of hard asphalt.

Another notable patent is the "Deep separation method and processing system for the separation of heavy oil through granulation of coupled post-extraction asphalt residue." This invention utilizes granulation of coupled post-extraction asphalt residue to achieve deep separation of heavy oil. A dispersion solvent is introduced into the asphalt phase after separation by solvent extraction, leading to a rapid phase change in a gas-solid separator. This process disperses the asphalt phase into solid particles while the solvent vaporizes, allowing for low-temperature separation of asphalt and solvent with adjustable sizes of asphalt particles. The method includes a three-stage separation of heavy oil feedstock, maximizing the yield and quality of the deasphalted oil while simplifying the process flow and reducing investment costs.
