The experimental program described here began shortly after a visit to a natural gas liquids (NGL) plant which uses the relatively inexpensive method of dehydration and freeze protection based on methanol[1,2] rather than solid desiccants. The cold feed exchanger (see Fig. 1) exhibited symptoms of freezing of the methanol/water mixture passing through the exchanger. An actual inspection of the exchanger showed that the symptoms had been caused by an accumulation of dust and light lubricating oil. However, a program of experiments was launched to provide detailed data on the ultimate physical limits to low-temperature operation of this sort of NGL plant.
