CCS (Carbon Capture and Storage) is one of the technologies which can be used to decrease carbon dioxide (CO2) emission. It consists of three main processes: CO2 capturing process, CO2 transportation, and CO2 storage. In order to run those processes, several kinds of equipment are needed, one of them is the pressure vessel. CCS technology which implemented on the natural gas central processing plant in Gundih, Blora Regency has pressure vessels that, some of those, used to accommodate and store CO2 liquid temporary. Working pressure and temperature of CO2 is about 20 bar and -20 oC respectively. Based on those needs, design pressure vessel which is able to perform those function well is needed. The pressure vessel designed in this Final Project is a vertical pressure vessel which has the capacity up to 50 kl, has design pressure for about 24,5 bar and - 45 oC for design temperature. The main reference of designing this pressure vessel is ASME code Section VIII Division 1. Several designed pressure vessel equipment are the shell, head, opening, and support. The process of designing pressure vessel includes determining the dimensions of the pressure vessel components and analyzing the strength of the pressure vessel. Strength analysis of the pressure vessel is done by using the finite element method (FEM) which is processed through software simulations, ANSYS Workbench 15.0. Design results of pressure vessel are the inside diameter of 2.61 m, the height of 10.3 m, opening with NPS 6-in and 20-in, the nominal thickness of the shell and the head (ellipsoidal 2:1) of 1.5 in. Meanwhile, maximum equivalent stress that occurs in the shell and the head of the simulation results, respectively, is 85 MPa and 176 MPa. It does not exceed maximum allowable stress 138 MPa for the shell and 207 MPa for the head, so the pressure vessel will be safe.
