摘要：

There are many industrial heat exchanger applications where chemical additives cannot be used to mitigate severe fouling problems, due to product purity requirements, operating conditions or economic considerations. A fundamental approach to reduce the impact of heat exchanger fouling on such process plant operation is demonstrated, using the Kraft pulping process and the Bayer bauxite refinery process as examples. Both processes suffer from rapid deposit formation, which renders the heat exchanger train the bottleneck of plant operation. A combination of fundamental studies, laboratory and plant measurements was used together with models of the actual heat transfer process, to predict optimum operating conditions and schedules.
