Analysis of Sustained Load and Nozzle Load Stresses on the Inlet and Outlet Pipe Vent Knock Out Drum

Abstract

Abstract - A vegetable oil production company located in Gresik, East Java is currently constructing a new plant, namely the New Amine Production Facility. In the production process of this amine compound, there is a Vent Recovery Unit where there is a Vent Knock Out Drum vessel with inlet and outlet pipelines. The pipelines in this flare system has 3 line numbers with a design pressure of 65.27 psi and a design temperature of 482Β°F, therefore this is a new design and the load received by the pipe is very large, so manual calculations, designs and simulations are required by computer. Stress analysis focuses on static stress analysis, allowable pipe span of the pipe which includes stress due to sustained load, and nozzle load. From the above problems analyzed by comparing manual calculation with running results on CAESAR II software so that the stress value can be determined according to the limits of ASME B31.3. The results of manual calculations show the sustained loads and CAESAR II software show the sustained loads and nozzle loads on the piping system is below the allowable limit value. So, from the results of the analyzed calculations or CAESAR II software states that the piping system is safe when operating
