Latest Patents

Avaullee holds a patent for a process aimed at purging propane in a polypropylene manufacturing process. This process involves polymerizing propylene in a polymerization zone, withdrawing an effluent, and directing it to a separation zone. The effluent is then processed through a splitter to produce both an overhead and a bottom stream. The overhead stream is recycled back to the polymerization zone, while the bottom stream is sent to a membrane separation zone to generate a permeate and a purge. Additionally, the bottom stream can be treated in a scrubber, with the scrubber's overhead also being directed to the membrane separation zone. This innovative approach allows for the recycling of the permeate back to the polymerization zone, thereby improving the overall efficiency of the manufacturing process.
