Low temperature

A low-temperature phase-change desalination process configuration is presented in this study. This configuration enables saline water to be evaporated at near-ambient temperatures under near-vacuum level pressures created by the barometric head without any mechanical energy input. Thermodynamic adva

Dimerisation of isobutene is of increasing interest to substitute oxygenated products such as MTBE or the like as fuel additives. Catalysts applied in commercial alkylation plants, e.g., hydrofluoric and sulfuric acid may be replaced by less harmful solid catalysts, for example by solid heteropolyac
