with preferential paths of vapour (关于蒸馏温控)? Temperature control(温度控制) An accurate control of the catalytic bed temperature by means of a specific cooling system. With a catalytic distillation temperature control is not so easy in case of olefins fluctuation in the feed. Exotherm developed by the olefin saturation tends to increase vaporisation with preferential paths of vapour and excess reflux is needed to ensure proper distribution of the liquid phase avoiding sacrificing on performances (sulphur in the product). 某技术与催化蒸馏 (catalytic distillation )在 操作方面的对比,请教标红句的意思 ? 查看更多0个回答 . 1人已关注
