Evaluation of Reaction Hazards for a Wiped-Film Evaporator
Abstract
A production plant desired to increase its capacity by raising the operating temperature of a wiped film evaporator (WFE) unit. The WFE separates a high-boiling product (taken overhead) from a heavy tar stream (taken out the bottom). Both the product and the tars will begin to decompose at temperatures near the operating temperature of the WFE. The plant' s Management of Change procedure required a consideration of reactivity hazards before making the proposed change in operating temperature. This paper will describe the experimental work that was done with ARC and Setaram C-80 instruments on plant samples and the estimation of decomposition kinetic parameters that was done using Thermal Safety software from Cheminform, Ltd. The results of this hazard evaluation allowed the plant personnel to make an informed decision about the proposed operating change.
