Abstract

The successful implementation of the industrialization plan  in Malaysia  in 1985 has led to change this country from an agricultural economy into industrial based economy. The industrial sector represents the highest consuming sector across all other sectors and accounts for about 48% of all total  energy demand. This study is concerned with an energy saving, economic and environmental analysis of industrial boilers in Malaysian paper and pulp industries when applying the concept of fuel switching. It has been found that 11,946 ton of CO2 and RM 1,872,532 could be saved annually, when switching between diesel fuel and biomass by a percentage of 50% for both instead of using 100% of diesel fuel. Also it has been found that 7,495,640 kg of CO2 and RM 923,431 could be saved annually, when switching between diesel fuel and natural gas by a percentage of 50% for both instead of using 100% of diesel fuel. All these results represent high energy saving, environmental and economic benefits for a small developing country like Malaysia.

Abstract

The depletion of fossil fuels, rising of earth temperatures and declining of air quality are an unavoidable phenomenon today. Bioethanol fuel is one solution to reduce this problem that comes from renewable raw materials. The purpose of this study is to investigate engine performance and exhaust emissions at gasoline engine by using the sorghum seeds bioethanol-pertalite blends with different mixed ratios (10%, 15%, and 20%). The test is performed on a four-stroke gasoline engine without modification. Engine speeds vary from 1000 to 4000 rpm, and properties of the sorghum seeds bioethanol-pertalite blends are measured and analyzed. In addition, engine torque, brake power, brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) as well as carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) emissions are measured. The results show that BSFC decreased while BTE increased for a fuel blends containing 20% bioethanol at 3500 rpm engine speed, with each maximum value of 246.93 g/kWh and 36.28%. It is also found that CO and HC emissions are lower for the sorghum seeds bioethanol-pertalite blends. Based on the research results, it can be concluded that the sorghum seeds bioethanol-pertalite blends can improve engine performance and reduce exhaust gas emissions. Keywords: bioethanol; pertalite; performance engine; exhaust gas emission; alternatif fuel.
