Abstract:
Increasing production of crude palm oil in Indonesia comes along with severe pollution of liquid waste. This waste called palm oil mill effluent (POME) is harmful for environment if no proper handling is carried out. Conventionally, biochemical technologies were employed to utilize POME as source of energy and valuable nutrients. However, this method requires large treatment area as well as long reaction time. Supercritical water gasification (SCWG) is a potential technology to overcome this problem. Here, SCWG was used to produce inorganic phosphorus from organics contained in raw POME. A continuous reactor was employed in this study and a set of experiments were developed to spotlight the behavior of phosphorus conversion from POME in SCWG. It was found that organic phosphorus was converted into inorganic phosphorus in the liquid phase, in which some precipitation of the inorganic phosphorus was observed in the reactor. The rate of this conversion increased with temperature. The discussions of this behavior were developed based on comparison of mathematical model and experimental results.
