Since the nature (quality) of bottom ash, multiclone ash and ESP ash varies substantially within a mill, combining these streams would lower the beneficial use potential of the individual streams. As such, source segregation of the generated ash streams could ensure consistent quality ash streams useable for specific applications.

The amount of the bottom ash generated by palm oil mill is therefore predicted to increase. The bottom ash from boiler is usually disposed at no cost at the mill sites (Awal and Hussin, 1999). Hence, the profuse sources of POMB bottom ash at low cost make it to be an economic choice of adsorbent for boron removal in industrial …

The experiment was conducted the day after the ash was collected from the mill. Palm oil mill boiler bottom ash is generated during the mechanical vibrating gate operation in the furnace. Palm oil mill boiler-retained ash is produced during the flow of the resulting flue gases, during which the gases are trapped in a baffle of the boiler.

Bottom ash from palm oil mills is used for this investigation. Characteristic tests and CO 2 adsorption processes have been conducted [26, 31, 32], and bottom ash is acceptable for the CO 2 adsorption method [33]. This is due to the lowest inlet velocity, the longer the contact time between the adsorbent and CO 2.
