Venturi scrubber - the solution for palm oil boilers emission control

Mohammed I .A . Nashbat, . (2001) Venturi scrubber - the solution for palm oil boilers emission control. [Proceedings Paper]

Air pollution sources in palm oil mills are mainly from boilers and incinerators. Black smoke and particulate are the main air pollutants. Biomass-fired boilers are all plagued by the problem of firing very high moisture content organic materials. It is extremely difficult to generate a sufficient high temperature flame in such boilers to completely combust the carbon. As a result virtually all biomass-fired boilers have problems with black smoke which is simply unburned carbon. The type of biomass burned has almost no impact on the combustion efficiency. To meet the current emission regulations required by DOE a fibre and shell palm oil fired boiler must be equipped with a high efficiency emission control device. There are very few areas where multiple cyclone collectors will suffice. Wet scrubbers dry scrubbers and to a lesser extent bag houses and precipitators are used in these applications. In general bag houses and precipitators are used in these applications. In general the wet scrubber has been favoured in recent years. However it has the disadvantage of producing a liquid waste stream which must then be disposed of. Dry scrubbers eliminate this liquid waste discharge but performance results to date are not as encouraging as those obtained with wet scrubbers. The particulate matter from a palm oil boiler typically has low electrical resistivity and as a result is not efficiently collected in an electrostatic precipitator. Bag house are not used extensively on palm oil boilers because of the potential fire hazard associated with the unburned and partially burned particulate matter.

Abstract

Air pollution sources in palm oil mills are mainly from boilers and incinerators. Black smoke and particulate are the main air pollutants. Biomass-fired boilers are all plagued by the problem of firing very high moisture content organic materials. It is extremely difficult to generate a sufficient high temperature flame in such boilers to completely combust the carbon. As a result virtually all biomass-fired boilers have problems with black smoke which is simply unburned carbon. The type of biomass burned has almost no impact on the combustion efficiency. To meet the current emission regulations required by DOE a fibre and shell palm oil fired boiler must be equipped with a high efficiency emission control device. There are very few areas where multiple cyclone collectors will suffice. Wet scrubbers dry scrubbers and to a lesser extent bag houses and precipitators are used in these applications. In general bag houses and precipitators are used in these applications. In general the wet scrubber has been favoured in recent years. However it has the disadvantage of producing a liquid waste stream which must then be disposed of. Dry scrubbers eliminate this liquid waste discharge but performance results to date are not as encouraging as those obtained with wet scrubbers. The particulate matter from a palm oil boiler typically has low electrical resistivity and as a result is not efficiently collected in an electrostatic precipitator. Bag house are not used extensively on palm oil boilers because of the potential fire hazard associated with the unburned and partially burned particulate matter. This paper compares the different technologies used for palm oil boilers air pollution control.
