Reflux failure 5. To illustrate the point above, consider the loss-of-reflux overpressure scenario for the depropanizer tower system depicted in Figure 1, which can be caused by either a failure of the reflux pump (P-1/2) or a closure of the flow control valve (FV-2). Pressure excursions above design pressure could potentially result in leaks or rupture and consequential loss of containment. . . Control valve failure 6.
