Heat Integration Study of Biomass Gasification Plant for Hydrogen Production

Hydrogen is found to be the most important source of sustainable, renewable and clean
of energy. As the world is facing global warming crisis and environmental problem due
to usage of fossil fuels as major energy source, the potential of hydrogen as an
alternative source of energy is highly regarded. This project aims to develop process
simulation of selected flowsheet by using Aspen Plus software. Heat integration
development has been applied by using Pinch Analysis technique and carried out in
Process Integration Software (STAR). The temperature difference is set at 10. The
minimum hot utility required is 0.1642 kW while the minimum cold utility required is
0.05456 kW. Maximum heat recovery from the process is 0.8413 kW. By obtaining
problem table algorithm, the pinch temperature is at 628.54oC. Three heat exchangers
are proposed to be used result from heat exchanger network development. Calculation of
energy saving show around 72% of hot utility and 88% of cold utility can be saved by
doing heat integration technique.
