Abstract

To date, a high energy demand has led to massive research efforts towards improved gas-separation techniques for more energy-efficient and environmenttally friendly methods. One of the potential alternative energies is biogas produced from the fermentation of liquid waste generated from the oil-extraction process, which is known as palm oil mill effluent (POME). Basically, the gas produced from the POME fermentation process consists mainly of a CO2 and H2 gas mixture. CO2 is known as an anthropogenic greenhouse gas, which contributes towards the climate change phenomenon. Hence, it is crucial to determine a suitable technique for H2 separation and purification with good capability for CO2 capture, as this will reduce CO2 emission to the environment as well. This paper reviewed the current gas-separation techniques that consist of absorption, adsorption and a membrane in order to determine the advantages and disadvantages of these techniques towards the efficiency of the separation system. Crucial aspects for gas-separation techniques such as energy, economic, and environmental considerations are discussed, and a potential biohydrogen and biogas-upgrading technique for industrial POME application is presented and concluded in this paper. Based on the comparison on these aspects, water scrubbing is found to be the best technique to be used in the biogas-upgrading industry, followed by membrane and chemical scrubbing as well as PSA. Hence, these guidelines are justified for selecting the best gas-upgrading technique to be used in palm oil mill industry applications.
