Solution Provided | Digestor Pressure Safety Valve Inlet Manifold Assessment
Discipline | Process, Mechanical
Carnac was engaged to assess the effect of product or scale build up within a manifold at the inlet of the Digestor Pressure Safety Valve at an Alumina Refinery. Carnac developed a hydraulic model in FFDS for each of the Digestor vessels’ PSV inlet manifolds and determined whether or not the pressure loss across the manifolds fell within 3% of the maximum pressure loss allowed by AS1210. This also included the case where effective hydraulic diameter was reduced due to deposition of scale.
