Oil and natural gas are an essential part of our everyday lives. Oil and natural gas are stored inside the earth and is extracted to be then refined into products used in our daily lives such as fuel for our vehicles, cooking oil to create foods, and many more. After extracting the fluids underground, the fluids are still mixed with each other. To separate them, an equipment called separator is used to separate the extracted fluids into natural gas and crude oil. The separator itself is a pressure vessel due to it containing fluids at a high pressure. The separator in this undergraduate final project is designed based on the ASME Section VIII Div. 2 and an existing separator. From the existing separator, a higher operating pressure and a higher capacity is chosen leading to a new diameter and a new design pressure. The new diameter and design pressure is then used to determine the dimensions of all the parts of the separator. These dimensions will be used to create a 3D model as well as to create an engineering drawing of the separator. The 3D model is then imported into a simulation program to determine its performance under design pressure and hydrotest pressure. The result obtained from the simulation shows that the maximum equivalent stress experienced by the separator has a value of 257,52 MPa at design condition and 311,97 MPa at hydrostatic condition which is under the yield strength of the chosen material for the separator which has a value of 415 MPa. Thus, the separator is concluded to satisfy the ASME Criteria Code with a safety factor of 1,62 under design pressure and 1,33 under hydrostatic condition.
