Simulation software

ECLIPSE developed by Ulster University and used for techno-economic analysis of power systems.

Uses generic chemical engineering equations and a capitalcosting program with over 100 equipment types.

Chemical compound properties and plant cost database can bemodified to allow new or conceptual processes to be evaluated.

Techno-economic assessment studies are carried out in stages;initially a process flow diagram is prepared, technical design datacan then be added and a mass and energy balance completed.

Conclusions

It is feasible to use jatropha oil as the fuel to run a

diesel engine genset based Trigen and CHP

The efficiencies of the Generator, Trigen and CHP run

by jatropha oil are a little lower but comparable to thatrun by diesel, respectively

The efficiencies of Trigen and CHP are all higher thanthat of Generator

The SFCs of Trigen and CHP are all lower than that of

Generator
