In some industrialized countries, there is a widespread view that greenhouse gases produced from burning fossil fuels produces that will lead to ever increasing global atmospheric temperature changes. The scientific case for man-made global warming or climate change is not proven. If unchecked, global warming advocates will burden the global economy with costly regulations on carbon dioxide (CO2) emissions, penalties on fuel consumption, premature introduction of unproven and uneconomical alte

When process engineers design distillation columns, they primarily pay attention to selecting the required number of trays or packing height and column diameter in order to achieve target performance. As a result, distillation column feed condition is often overlooked. Improper feed design downgrades distillation column performance and influences unit economics. This article illustrates useful methodologies of distillation column feed design optimization. Selections of feed stream phase, loc

In one of the world's largest PX production facilities, GTC has licensed CrystPX, proprietary process technology to purify paraxylene. The article details the technology and its application at LG-Caltex in Yosu, Korea.

Real retrofit examples demonstrate how crude units can be successfully optimized with the crude slates currently being processed. Process design strategies are discussed in detail and highlight how retrofit targets are achieved.
