Abstract: While conducting research for dioxin emission factor for stationary source emission, it is found that some factors come from overestimation. The cause of discrepancy for estimating process comes often from lacking understanding of the process. The result of this study for secondary aluminum refining emission factors indicates that if raw materials are scraps, the factors averaged at 541 ng I-TEQ/Ton-raw materials. If waste aluminum is used as the raw material, factors averaged at 1338 ng I-TEQ/Ton-raw material. The factors based on site sampling for coal-fired power generation process is 24.84-549.62 ng I-TEQ/Ton-fuel. It varies according to coal sources. Emission factor for cement producing process is 95.4-102.66 ng I-TEQ/Ton-raw material. Due to fewer differences in operating traits, raw materials and fuel application for cement producing process, emission factors have smaller differences. The reliability for emission variables is relatively higher.

Abstract: In early 2006, Fives Solios, namely Solios Thermal, was selected as a key cast house supplier by a major aluminium producer for a new 130,000te/yr re-melting facility. The project scope included not only the supply of modern melting and holding furnaces plus ancillary equipment, but also pre-heating furnaces, an air pollution control system, basic cast house engineering, cooling water schemes and complete turnkey project management. This project presented particular technical and logistical challenges and was required to meet exacting European environmental / efficiency standards for all major contractors involved. The facility was commissioned in March 2008 and the first production was on schedule. This paper will discuss the challenges that the Solios Thermal project team had to overcome, from layout of equipment to conclusion of the project; also how good communication and close collaboration between the customer and all major subcontractors resulted in a successfully implemented plant.
