Abstract: The process check for kettle type rebolier based on Aspen B-JAC was discussed in this paper by using a new kettle type reboiler in Cangzhou refinery tail gas desulfurization solvent regeneration unit as an example introduced. The discussed simulation can be used as a reference for the design and checking of new kettle type reboiler. This paper also evaluated the advantages of the heat exchanger in anti-corrosion, energy saving, environmental protection and improvement of products quality.
