CO2 REMOVAL: BETTER PERFORMANCE FOR LESS ENERGY

L. Tomasi, Chief Process Engineer
Giammarco-Vetrocoke, Venice - Italy

One of the prime candidates for revamping in the ammonia plant is the CO2 removal unit. Giammarco-Vetrocoke uses a hybrid regeneration system to attain the best energy economy.

Revamping the carbon dioxide removal unit in an ammonia production line represent one of the most economically interesting of the available expedients for making old plants competitive with newer ones. It provides the opportunity for simultaneously improving reliability, saving energy, and increasing capacity.
Over more than 40 years, Giammarco-Vetrocoke (GV) has acquired extensive experience in designing acid gas removal systems for a wide range of applications and clients' requirements. GV's current technology is as energy-efficient as any on the market.
