VALUE PROPOSITION Per- and polyfluoroalkyl substances (PFAS) are a widely used but toxic and carcinogenic group of man-made chemicals. They are extremely resistant to degradation and will persist in the environment and in the human body. PFAS are highly water soluble, thus contaminated drinking water is the primary source of exposure. The most common...

Falling Bed Plasma Reactors

VALUE PROPOSITION A large variety of applications require powdered materials to be treated by plasmas. Most applications used in the industry and research labs have a static configuration, where the powder samples are placed in a tray and stay still during the process. This is ineffective if the powders pile up in multiple layers since the plasma...

RAPIDClean: fast, accurate real-time simulations for hole cleaning operations

Problem statementImproper hole cleaning is a major cause of non-productive time (NPT) in drilling. Current hole cleaning practices are mostly based on experience, rules of thumb and simplistic calculations, and do not necessarily work as expected in all scenarios. Available models do not include parameters such as fluid compressibility, pipe rotation...

System for Coating Inner Diameter Surface

Executive SummaryDiamond-like coatings offer a coating solution rivaled by few technologies available today. Capable of improving the durability and extending the lifetime of many metallic products, these coatings are typically applied in Physical Vapor Deposition (PVD) chambers. PVD processing is a line-of-sight process, meaning the distance between...
