Utilization of Structured Packing for Energy Savings in Distillation and Absorption Columns
MetadataShow full item record
As the need to reduce production costs causes manufacturers to re-evaluate processing schemes, high efficiency structured packings are increasingly recognized as an effective alternative for reducing energy consumption in heat and mass transfer operations. In distillation, the high efficiency and low pressure drop of structured packing results in better product purities and/or recoveries. For heat sensitive materials, where the bottom temperature is critical, a decrease in operating pressure reduces thermal degradation. Direct contact condensers, absorbers, and strippers are also good applications for structured packings. The high efficiency, inherent low pressure drop, and high throughput capacity of such packings provide improved operating flexibility and cost savings. In addition, smaller diameters and column heights result from the use of structured packings. This is especially important in off-shore applications where space and weight limitations exist. This paper describes why various structured packings are the product of choice in such diverse applications as petroluem refining, gas processing, ethylene plants, and styrene fractionation trains.
