Latest Patents

Li’s latest patents address ways to combine equipment and processing steps used to recover propylene and other hydrocarbons.

“Dehydrogenation and Pyrolysis Product Recovery with a Common C3 Splitter” describes a process and apparatus that integrate propylene recovery from pyrolysis and paraffin dehydrogenation streams. A shared C3 splitter separates propylene product from propane recycled to the dehydrogenation reactor, processing C3 hydrocarbons from both sources.

“Dehydrogenation and Pyrolysis Product Recovery with a Common Demethanizer” describes a system that couples a stripping column for a dehydrogenation stream with a demethanizer for a pyrolyzed stream. The stripping-column overhead, which contains C2− hydrocarbons, is fractionated in the demethanizer alongside the pyrolyzed stream. The patent describes how this arrangement can eliminate the need for a conventional deethanizer column and a separate refrigeration system in the propane dehydrogenation unit.
