Latest Patents

Chenggang He holds a patent for a method that refines styrene using combined falling film reboilers and heat pump technology. This method provides the necessary heat source for a separation column. The patent outlines a process where high-concentration gas-phase ethylbenzene is separated from a low-pressure ethylbenzene/styrene column. This ethylbenzene is then either directly pressurized or used to gasify a heat pump working medium, which is subsequently pressurized. The resulting high-concentration gas-phase ethylbenzene serves as a heat source for the pre-separation column and/or the styrene product column in the styrene separation process.
