A hybrid technology combining heat pump and thermally coupled distillation sequence for retrofit and debottlenecking

摘要: Abstract Increasing the capacity of an existing distillation process has been a major focus chemical industry. On other hand, entrainment flooding can occur as result, which create bottleneck in process. This paper reports results techno-economic feasibility study to debottleneck column using proposed hybrid combining heat pump and thermally coupled sequence. Fractional utilization area was used identify problems well how much is available for vapor flow on stage. A aided sequence (HPTCDS) designed optimized response surface methodology. Two cases were examined test The showed that achieve significant energy savings remove problem.
