Pearlhill Technologies has unique specialized capability for fluorine extraction from depleted uranium tetrafluoride (DUF4, a “green salt”). DUF4 is obtainable from chemical processing of depleted hexafluoride (DUF6) that is a product of uranium isotopic enrichment plants (UIEPs). Pearlhill employs new, environmentally and economically sound processes in our patents for the production of nonmetallic inorganic fluorides from uranium tetrafluoride (NIFUT), including sulfur tetrafluoride (SF4), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) gases.
Pearlhill Technologies captures and separates high tonnage of 99.995% purity CO2 at coal plants. Our patent describe our Photolytic CO2 capture process. We feed our CO2 product into the production of dry ice (blocks and pellets), and liquid CO2 products. Our photolytic technology recovers CO2 at below 110 F, producing the ultra-low disintegration of capture medium, and cost US$80-120/t CO2 captured. Pearlhill collaborates with ASCO CO2 for building our dry ice production plants.
The Small Business innovation research (SBIR) program funded Pearlhill Technologies R&D for the creation of new processes for the conversion of DUF4 for commercial production of a number of high-value fluorine products, which are absorbable in high volume by the current markets for fluoride chemicals. Pearlhill’s fluorine products command higher price per fluorine atom in the composition than hydrogen fluoride (HF, the product created chemical in the current uranium recovery process).
Pearlhill R&D on fabrication of electronic sensors is in collaboration with Professor Kris Campbell of the department of computer and electrical engineering at the Boise State University. Our ongoing work covers the following areas:
- Magnetoreception sensors
- Plant memristor biosensors
- Communication electronics
