THE HEATING PATTERN OF THE MICROWAVE DEHYDRATOR FOR TREATING PETROLEUM CRUDE OILS

The effect of microwave dehydrator (modified domestic microwave oven) different types of petroleum oils were investigated in this paper, since microwave heats material selectively and volumetrically in relatively short time, and since its application in treating petroleum emulsion is tremendously recommended, thereof, it is the aim of this paper to investigate the microwave induced heating capacities of the individual components of the petroleum emulsion mixture. Three types of crude petroleum oils and water samples were put into test, from the result of this study, the temperature profile was observed to proceed as follow, at the first 20 seconds, all samples had similar temperature profiles in the range (50-60 C), however, beyond 20 seconds there was a clear distinct trend for every sample, in the interval from 20 seconds to 110 seconds, water sample had the curve with the highest temperature profile followed by UAE crude oil, then Saudi Arabia oil. Beyond 110 seconds, Kuwait crude oil had the maximum temperature profile continued sharply without reaching any plateau, followed by UAE then Saudi Arabia crude oil. The volumetric rate of heat generation also found to be in such a way that water sample had the maximum numerical value in the range (1-1.2 cal/s.cm 3) at the beginning then decays as the heating time goes on, followed by that of Kuwait oil (0.8-1 cal/s.cm 3), then Saudi Arabia crude oil (0.6-0.8 cal/s.c
