Vapor recompression heat pumps are used in distillation processes to reduce energy consumption. For sub-ambient distillation, one of the largest difficulties is to produce liquid reflux since the condensation of highly volatile components requires expensive refrigeration energy. Thermally...

This work compares two classes of exergy efficiency definitions and applies them on a simple process (i.e. PRICO) for the liquefaction of natural gas. This comparison demonstrates the possible inconsistency and uncertainty of several exergy efficiency definitions already proposed in the...

Oxy-combustion is a competitive technology to capture CO2. Current air separation technologies for high volume O2 production are based on cryogenic distillation. When a double-column distillation cycle is applied to produce O2 with a purity of 95 mol%, the oxygen production process is causing...

A novel energy and cost effective transport chain for stranded natural gas utilized for power production with CO2 capture and storage is developed. It includes an offshore section, a combined gas carrier, and an integrated receiving terminal. In the offshore process, natural gas (NG) is...
