The Isolmalk-2 technology has a successful track record in achieving more than satisfactory results. The start up and operation of the unit at the Omsk refinery marks the appearance of a stable and environmentally safe alternative to chlorinated aluminum oxide systems in a world scale unit.

High-performance tray does not itself determine the effectiveness of the whole column. Other distillation equipment plays a vital role in a successful column revamp.

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.
