Predicting HPGR performance and understanding rock ...
High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in ...

Simplifying hydrogen production
Several of the catalysts in a hydrogen plant flowsheet are sensitive to poisoning, especially by sulphur. In most cases, the sulphur is removed to very low levels by the purification section. However, upsets occur when the sulphur level spikes well above the design value, thereby allowing sulphur into the plant.
