Optimisation of biomethane from palm oil mill effluent for offsite utilisation

Palm oil mill effluent (POME) is a source that can be used for biogas generation that can be a substitute for fossil fuel. High content of biological oxygen demand and chemical oxygen demand of POME has the advantage to produce large amount of biogas through anaerobic digestion. The purpose of this...

High content of biological oxygen demand and chemical oxygen demand of POME has the advantage to produce large amount of biogas through anaerobic digestion.

The sensitivity analysis revealed that the price of CBM has an impact on the model. Sensitivity analysis suggested that the CBM sales price should be at least 8.2 USD/MMBtu to be economically feasible and 12.9MMBtu to be profitable. In addition, a subsidy of 2.67 USD/MMBtu should be imposed for CBM project to ensure its economic viability and 7.37 USD/MMBtu to be a more economically attractive option than utilised as electricity. 2021 Thesis http://eprints.utm.my/102627/ http://eprints.utm.my/102627/1/AminullahMohtarMSChE2021.pdf.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:145640 masters Universiti Teknologi Malaysia Faculty of Engineering - School of Chemical & Energy Engineering
