Biodiesel report Agriculture and industry utilize the diesel-powered engine for a multitude of purpose, but the supply of petroleum derived diesel fuel is limited. The depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons stimulated the search for alternative sources for petroleum based fuels especially for diesel fuels. One of the solutions to this problem is by using biodiesel. Biodiesel is a diesel fuel substitute produced from renewable sources such as vegetable oils, animal fats and recycled cooking oils. Chemically, it is defined as the mono alkyl esters of long chain fatty acids derived from renewable lipid sources. There are many biodiesel plants around the world. One of it is the Sime Darby Biodiesel Plantations Berhad which has plant located at East Estate, Carey Island, Selangor. Biodiesel there is produced through a process called transesterification where a vegetable oil which from palm oil trees is reacted with methanol or ethanol in the presence of a catalyst to yield glycerine

Unformatted text preview: and biodiesel (chemically called methyl or ethyl esters). Biodiesel can be used in neat form or blended with petroleum diesel for use in diesel engines. Its physical and chemical properties as it relates to operation of diesel engines are similar to petroleum based diesel fuel. At an average, about 0.1 tonne of raw Palm Oil Mill Effluent (POME) is generated for every tonne of fresh fruit bunch processed. POME consists of water soluble components of palm fruits as well as suspended materials like palm fibre and oil. Despite its biodegradability, POME cannot be discharged without first being treated because POME is acidic and has a very high biochemical oxygen demand (BOD). At Sime Darby Plantation, the following effluent treatment systems are implemented which are Anaerobic Digestion System, Extended Aerobic Process and bio reactor system. The advantages of using biodiesel are it is non-hazardous and biodegradable....
