Abstract:
A process simulation model was developed for biogas production via an anaerobic digestion process using Advanced System for Process Engineering (Aspen) Plus software. A total of 46 reactions were included in the model and were simulated with appropriate kinetics. For anaerobic digestion of Palm Oil Mill Effluent (POME), few studies have been reported with regards to simulation, and this biogas model has not been validated for use with POME. These works validate the ability of the developed model to predict biogas production using established data on biogas production from literature namely (O-thong et al.,2016; Mamimin et al., 2015). Average Absolute Deviation (AAD) was computed, and a deviation calculated less than 5% was obtained for both case studies of biogas production from POME with the model. The developed model was also used to study the effects of adding an external supply of H 2 and CO 2 at different ratios (2:1, 1:1). The results showed that the ratio of H 2 and CO 2 , 2:1, has higher methane production compared to an equal ratio of H 2 and CO 2 , 1:1. The developed model is flexible and able to estimate the enhancement of methanation via the input of an external supply of H 2 and CO 2 quantitatively.
