Abstract: Energy conservation and PAHs (polycyclic aromatic hydrocarbon) control are two challenges for the iron and steel industry, especially where the industry has developed at high speed. How to select appropriate technologies to improve energy efficiency and control pollution from PAHs simultaneously is encountered by both the researchers and the decision makers. This study sets up a framework on technology selection and combination which integrates technology assessment, multiple objective programming and scenario analysis. It can predict proper technology combination for different emission controls, energy conservation targets and desired levels of production. An iron and steel factory in Southwestern China is cited as a case. It is shown that stricter PAHs control will drive the transformation from process control technology to alternative smelting technology. In low PAHs limit, 25% energy reduction is a threshold. Before inclusion of a restraint on energy consumption at 25% reduction, PAHs emission is the key limiting factor for the technology selection; while after inclusion of this restraint, energy consumption becomes the key limiting factor. The desired level of production will also influence the technology selection. This study can help decision makers to select appropriate technologies to meet the PAHs control objectives and energy conservation strategies in energy-intensive industries.
