A step toward ammonia production at ambient conditions

Many investigations are ongoing to achieve ammonia synthesis at energy-saving mild conditions instead of the high temperatures and pressures (500°C, 300 atm) required by the commonly used Haber-Bosch process, which consumes more than 1% of the world’s power production. Now,…

Ceramic membranes and O3 combine to treat wastewater

High fluxes and micro-contaminant reduction have been achieved in a 2.5-m3/h pilot plant to test the performance of ceramic membranes and ozonation in treating wastewater at Melbourne Water’s (www.melbournewater.com.au) Eastern Treatment Plant. The project, to be completed in a few…

Ethylene in FCC off-gas is upgraded to motor fuels

A typical fluid catalytic cracking unit (FCC) generates about 200 tons/d of dry gas — a mixture of off-gases that is burned as refinery fuel. However, about 40 tons of that gas is ethylene, which would have much greater value…
