Our Technologies 

General Information

INVISTA offers other technologies for license from its extended patent estate portfolio and vast breadth of know-how in diverse areas.  These include N2O abatement technologies for use in plants manufacturing adipic acid, (C6H10O4, AA) or nitric acid (HNO3).

Beyond our core technologies in polyester, spandex and nylon value chains, IPT collaborates with other innovative technology companies to combine strengths and deliver unique opportunities to our licensees in other technology areas.

IPT and Beijing Huiersanji Green Chem Co., Ltd. (Green Chem), a Beijing-based technology licensing company, have reached an agreement to enable INVISTA to license Green Chem’s fluid catalytic cracking (FCC) offgas technology outside of China.  The process, which will be marketed as DTL™ process technology outside of China, is a dry-gas-to-liquids technology that allows for flexible conversion of light olefins, present in FCC offgas, into either gasoline and distillate or concentrated aromatics, significantly increasing their value. This cost-effective solution captures the gas-to-liquids spread associated with FCC offgas upgrading and has a small equipment footprint when compared with process alternatives.
