After cooling of the top product and separation to obtain the volatile gaseous fuel from the liquid fuel oil, the volatile gaseous fuel alongside air were pressurized with a compressor and then combusted in a Gibbs free energy reactor.
COMBINED HEAT AND POWER SIMULATION ON ASPEN HYSYS CRACK
The pyrolysis reactor modelled as a conversion reactor was used to thermally crack 2000Kg/h of HDPE feed at a temperature of 450☌ to produce a top product containing a mixture of liquid fuel oil and volatile gaseous fuel. A simulation model that produces electricity from the High Density Polyethylene (HDPE) waste plastics has been developed using Aspen Hysys process simulator. This paper presents a theoretical framework for the simulation of waste plastic power plant. Where recycling becomes an issue, technologies that utilize the waste plastics to generate electricity can be employed. Non-recyclable plastic materials are used in areas like packaging, 3D printing, and construction. The recovery of this abundant energy helps to curb environmental concerns associated with plastic utilization. If excess heat is available it should be used to preheat the feed air.The high energy content of plastics can be converted to electricity.

Base on the results, it was found that the optimum gasification temperature should be kept around 750-850 ℃, the steam to biomass ratio should be kept around 0.4-0.6. The gasification results behaved a little different when the steam to biomass ratio and the gasification temperature are low. Increasing the gasification temperature resulted in the decrease of the gasification efficiency and the hydrogen yield, while it had positive effect on the increase of the LHV of the syngas. Increasing the steam to biomass ratio results in the increase of the hydrogen yield and the proportion of hydrogen content in the syngas, while the increase of the S/B had negative effects on increasing the LHV of the syngas and the gasification efficiency. Preheating air is more effectively than preheating the steam. The sensitivity analysis results indicated that both preheating the feed steam and air have positive effect on increasing the LHV of the syngas and the gasification efficiency. The effects of changing the parameters on the output syngas composition, LHV of the syngas, char split fraction and the gasification efficiency were studied. The key operating parameters including the feed steam temperature, feed air temperature, steam to biomass ratio, and the gasification temperature were varied using the sensitivity analysis block of Aspen Plus. The gasifier was modeled using minimum Gibbs free energy method.

The biomass gasification was studied based on the dual fluidized-bed gasifier developed by the Vienna University of Technology, which has been successfully demonstrated in Güssing, Austria.

Among the biomass utilization technologies, biomass gasification for combined heat and power is an attractive solution for utilizing biomass effectively. Counties all over the world are paying more and more attention to biomass because it can effectively reduce greenhouse effect due to its zero carbon dioxide emission. Biomass is an ideal renewable and clean energy resource.
