Successful implementation of a new extractive-distillation technology for aromatics recovery

AMT International Inc. (Plano, Texas; www.amtintl.com) and LG Chem, Ltd. (Seoul, Korea; www.lgchem.com) have successfully converted an existing sulfolane liquid-liquid extraction (LLE) unit at LG Chem’s Yeosu plant using a new extractive-distillation (ED) process for aromatics recovery. This technology was…

Cement technology increases strength and lowers emissions footprint

Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which…
