Abstract

Energy consumption in Thai manufacturing sector in 2009 was 23,798 ktoe and accounted for 35.7% of the final energy consumption of the country and the worth of purchased fuel and electricity in Thai pulp and paper industry accounted for over 7.7% or 1,836 ktoe of the energy consumption in manufacturing sector. The major energy consumed was coal, shared 86.0% of the energy consumption in this sector, followed by electricity and petroleum products which shared 9.4% and 4.5% respectively, natural gas and renewable energy consumption is small in pulp and paper manufacturing sector. The pulp and paper industry converts fibrous raw materials into pulp, paper, and paperboard. The processes of papermaking include raw materials preparation, pulping (chemical, semi-chemical, mechanical, or waste paper), bleaching, chemical recovery, pulp drying, and papermaking. The most significant energy consuming processes are pulping and the drying sections of papermaking. Energy efficiency improvement is essential for the reduction in energy usage, which in turn decreases the production cost, especially in times of high energy price mutability, and causes more profit. There are a variety of opportunities available at individual plants to reduce energy consumption, including a wide range of energy efficiency practices for organizational levels and energy-efficient technologies, i.e. steam generation and distribution systems, motors, pumps, air compressors, and combined heat and power system, that can be implemented at the component, process, and facility. Also provided is a discussion of the energy consumption characteristics of Thai pulp and paper industry along with a description of the major process technologies used within the industry. In addition to the specific energy consumption (SEC), the conservation supply curve (CSC) is derived in this study, base on a data from Thai pulp and paper industry. The curve shows the energy conservation potentials as function of the marginal cost of conserved energy (CCE), which can be useful for the energy efficiency improvement for other factories in Thai pulp and paper industry.
