Reactor fouling
WebAug 19, 2016 · The formation of fouling in slurry reactors as well as in its peripheral equipment, such as external heat exchangers, is attributed either to the deposition of oligomers (wax) or to the buildup... WebFouling is the accumulation of unwanted material on solid surfaces to the detriment of function. The fouling materials can consist of either living organisms or non-living substances (minerals or organic compounds). The layer of deposits represents additional resistance to heat transfer and causes the rate of heat transfer in a heat exchanger ...
