Latest Patents
Bian's latest patents include innovative methods for separating and purifying aromatic hydrocarbons. One notable patent is a method for separating aromatic hydrocarbons using extractive distillation. This method involves introducing a hydrocarbon mixture containing aromatic hydrocarbons into the middle of an extractive distillation column. An extraction solvent is then introduced into the upper part of the column. After the extractive distillation process, a raffinate containing benzene is discharged from the top of the column, achieving a benzene content of 3-40% by mass. The method ingeniously combines extractive distillation with liquid-liquid extraction, resulting in high purity and recovery rates while significantly reducing energy consumption.
Another important patent focuses on the purification of a solvent for the separation of styrene by extractive distillation. This method includes introducing a styrene-containing feedstock into the middle of an extractive distillation column, along with a solvent for the extractive distillation. The process allows for the recovery of crude styrene and the recycling of lean solvent, optimizing the separation process.
