讲座题目 Dividing Wall Column Technology Advances & Challenges

讲座时间1120日(星期五)上午10:00

讲座地点:西安交通大学教学二区化工学院办公楼202会议室

讲座内容:

In order to comply with globally proclaimed requirement for increasing sustainability of new designs, the economic incentives are so strong that inherently conservative process industries are interested in industrial development and implementation of energy saving distillation technologies. An encouraging technological breakthrough in this respect occurred in the mid-1980s, by introduction of the first Dividing Wall Column (DWC), i.e. a single shell, fully thermally coupled distillation column for obtaining three or four high purity products. Such a column as proven in many industrial applications in the meantime enables on average 30 % saving in energy and an equivalent saving in capital, accompanied by nearly halving the required plot area compared to conventional two or three column sequences. However, process industries seem still to be reluctant to implement a DWC. The main reason for this may be a lack of established design procedures and fear of unstable operation. Therefore these aspects have been addressed and as shown in this presentation encouraging advances in this respect made in a cooperative effort of academia, DWC manufacturers and users. In addition, it is shown that existing two or three column sequences could be transformed in a cost-effective way into a dividing wall column (DWC) to allow energy saving equivalent to that achievable in new designs. This makes DWC to an interesting retrofit option for process industries willing to achieve a substantial reduction in energy requirement and carbon dioxide emissions in existing plants. Additional benefit is reflected in the potential for increasing substantially the capacity of existing units in most sustainable way.
