Refinery membranes: where’s the IP?

This data-file reviews over 1,000 patents to identify the technology leaders aiming to use membranes instead of other separation processes (e.g.,  distillation) within refineries.

Covered companies in the screen include Air Liquide, Air Products,  Aramco, BASF, BP, Chevron,  Dow, ExxonMobil, GE, Honeywell, IFP, MTR, Praxair, Shell, WR Grace and Zeon. A brief overview is prented for each company, along with a summary of their recent patent filings, and all the underlying details.

Operational data are also presented for two interesting cases: Exxon’s recent refinery membrane breakthrough (chart below) and Air Products’s PRISM membranes for hydrogen separation.
