A multigeneration energy system with one fuel intake (sawdust biomass fuel) and five useful outputs is proposed and energy and exergy analyses are carried out to assess its performance. Instead of using a simple heat exchanger to satisfy district heating needs, applying a deaerator is found to result in 10% more hot water mass flow rate for the same conditions. The energy and exergy efficiencies of...
A novel cryogenic air separation process with LNG (liquefied natural gas) cold energy utilization that produces liquid nitrogen and oxygen is proposed and analyzed. Air separation process problems such as process configuration complexity, extreme operating conditions and high operating costs are covered. In this process heat from the top vapor stream of the column is recovered and exchanged with heat...
This paper examines heat recovery in a thermochemical Cu-Cl cycle for efficient hydrogen production. It is essential to recover heat within the Cu-Cl cycle to improve the overall thermal efficiency of the cycle. A major portion of heat recovery can be achieved by cooling and solidifying the molten salt exiting an oxygen reactor. Heat recovery from the molten salt is achieved by dispersing the molten...
