Modelling the performance of the morpholinium form condensate polishing plant at Oldbury Power Station

A computer code, MORPH42, has been developed to model the complex changes that occur to various ion exchange equilibria when mixed beds convert from hydrogen to morpholinium from operation. The model has been used to predict the performance of the condensate polishing plant at Oldbury Power Station which has operated in this mode for several years. MORPH42 successfully predicts the trends in sodium leakage that occur on the plant but currently underestimates the initial bed capacity for morpholine. The possible reasons for this are discussed in the context of pointing the way for further development. The basic model is not limited to morpholine form operation and can also be adapted for different amines and other ion exchange processes. (author)
