Redesign of a Pressure Vessel for Operation at 1.71 MPa

Pressure vessel is a liquid or solid fluid container made using metal materials with pressure in it. Pressure vessels also have a variety of shapes, which generally include horizontal, vertical, and spherical pressure vessels. The components of pressure vessels include top head, bottom head, shell, and nozzle. This study aims to obtain the geometry value of the pressure vessel which will be made geometry modeling that will be evaluated stress distribution, buckling, personal frequency, wind load so that the results will be obtained which can later be used as a design reference. This pressure vessel has a pressure of 1.71 MPa and has an operating weight of 16,698 kg, with a height of 6,539 mm and a diameter of 2,250 mm which will be installed in the Ujung Pangkah gas field Gresik, East Java, Indonesia. The pressure vessel will be used to develop the Ujung Pangkah oil and gas reserves by exporting gas to the power plant in Gresik after onshore separation and processing. The oil will be processed, stored and exported by bulk tanker. This research method includes literature study, data collection and processing carried out during the internship, after which geometry modeling using solidworks software and FEM analysis using ansys software. The results of this report find that the design of the pressure vessel is in accordance with the ASMESec.VII Div. 1 and has been validated using FEM analysis using ansys.
