Management of Renewable Sources of Energy: a Case on Rice Bran Oil and Vegetable Oils of Bangladesh Perspective

Md Mamunur Rashid
Bangladesh Institute of Management, 4 Sobhanbag, Mirpur Road, Dhaka-1207 (www.bim.org.bd).

Abstract/ Executive Summary:

Renewable energy is a now burning issue for sustainable development. Moreover, it is also environmentally compatible. Bangladesh produces huge amount rice every year. From this, a significant amount of wastes are generated from rice. Rice bran is one of them. On the other hand oil seeds such as coconut, soybean, pulm and mustard are available in Bangladesh. In this view, rice bran oil and vegetable oils are considered for a case study for renewable sources of energy and alternative fuel for lighting purposes of Bangladesh.

Objectives:

To find out the reasons of experimental findings, especially fuel properties of the oils, such as smoke point, pour point, cloud point, flash point and fire point etc.
To find the use of vegetable oils and rice bran oil, as an alternative of Kerosene oil

Methodology:

The following experimental analysis have been performed to determine fuel properties:

Cloud Point and Pour Point Determination: The cloud point of an oil temperature at which a hage or cloud first appears in the oil, when it is cooled. The temperature is below at which oil will not flows or be solidified or ceases to flow in pour point. It indicates the temperature below which the oil losses its fluidity and will out flow or circulate in a fuel system. The temperature, expressed as a multiple of 2°F (1°C), at which a cloud or hage or wax crystal appears at the bottom of the test jar, when the oil is cooled under prescribed conditions. When such inspection is hold, in the first cereal, a distinc cloudiness or hage in the oil at the bottom of the test jar is observed. At that time the record of the reading of the test thermometer as the cloud point. The lowest temperature, expressed as a multiple of 5°F (3°C), at which the oil is observed to flow, when cooled and examined under prescribed conditions for pour point.

Flash and Fire Point Determination: The temperature to which an oil must be heated, in order to give of sufficient vapors to form combustible mixture with air is termed the flash point. The fire point is defined as the minimum temperature at which an oil to continue burn after inflammable vapors with air mixture is ignited. This method of test covers the determination of the flash point of all mobile liquids flashing below 175°F (79°C), except products classified as grade No.4 or heavier fuel oil. The sample is placed in the cup of the tag closed tester and, with the lid closed, be heated at a slow constant rate. A small flame of specified size is directed into the cup at regular intervals. The flash point is taken as the lowest temperature at which application of the test flame has become the vapor above the sample to ignite. The next stage of flash point is fire point.

Smoke Point Determination: Smoke point is the maximum flame height that can be achieved without smoking. The sample of vegetable oils and rice bran oil is burned in an enclosed smoke lamp with normal scale. The maximum flame height that can be achieved without smoking is estimated.

Illumination of Light Intensity Measurement: Three different size lanterns were used for experiment to determine the illumination of light intensity i.e. of different fuel capacity, length and section any enclosure as usually used in the rural areas of Bangladesh. Illumination of light intensity of lantern, of different composition of rice bran oil and vegetable oils was measured by Luxmeter. The Luxmeter is a portable electronic photometer for the measurement of a wide range of illumination levels, which is presented and compared various types of renewable oils with mixture of Kerosene and different proportion of those oils.

Achievement/Findings:

Kerosene is blended with rice bran or vegetable oils as 4:1 proportion, then getting satisfactory result of lighting. Thus 20 % kerosene can be saved easily. Therefore, Rice bran oil and vegetable oils may be given higher priority as an alternative fuel for lighting purposes. For this reasons, the following points may be remarkable:

A government incentive is needed for the production of rice bran oil and vegetable oils.
Supply chain system can be implemented to collect and produce rice bran and vegetables oils.
Rice bran oil and vegetable oils may be given importance to use as an alternative engine fuel.
