High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will us ....High-resolution optical studies of solids nucleation in cryogenic processes.

Improvements and Optimisation of Water Electrolysis for Hydroxy Gas Production for Metal Cutting Applications. The current technique for metal cutting mainly uses oxygen-acetylene flames, which means for the large number of Australian remote communities oxygen and acetylene bottles have to be transported from major cities.
