二氧化碳提纯塔底重沸器选型研究

Research on Selection of Reboiler at Bottom of Carbon Dioxide Purification Column

二氧化碳产品在日常生活和工业中具有较广泛的应用。从天然气终端脱酸装置再生废气中可以回收二氧化碳,生产食品级液体二氧化碳。本文在分析二氧化碳回收利用的工艺技术基础上,对二氧化碳提纯塔底重沸器的选型进行探讨与研究,为其选型应用提供新的思路。

Carbon dioxide products have a wide range of applications in daily life and industry.Carbon dioxide can be recovered from the regenerated waste gas from the natural gas terminal deacidification unit to produce food grade liquid carbon dioxide.Based on the analysis of the process technology for carbon dioxide recovery and utilization,this paper explores and studies the selection of the reboiler at the bottom of the carbon dioxide purification column,which provides new ideas for its selection and application.
