DESIGN OF PRESSURE VESSEL PROJECT REPORT Submitted by\ MIJO JOSEPH VIPIN M VISHNU VIJAY ABSTRACT This project work deals with a detailed study and design procedure of pressure vessel A detailed study of various parts of pressure vessels like shell, closure, support, flanges, nozzles etc Design is carried according to rules of ASME code section VIII, Division I The first chapter deals with detailed study of pressure vessel i.e the various materials used in pressure construction and temperature are mentioned It also deals with the study of various parts like flanges, support etc Various methods of fabrication and testing are also included The second chapter includes design criteria This is followed by procedure of design, which include design shell and its components, nozzles, reinforcements etc LIST OF FIGURES FIGURE PAGE 3.9.1 TYPES OF FLANGES 14 3.11.1 TYPES OF SKIRT 17 MODEL OF AMINE ABSORBER 5.1 TOP AND BOTTOM HEAD 29 32 5.2.1 TOP SECTION OF SHELL 35 5.2.2 BOTTOM SECTION OF SHELL 36 5.3 DESIGN OF NOZZLE 59 5.4 DESIGN OF REINFORCEMENT AREAS 72 LIST OF TABLES DESIGN DATA RESULT AND DISCUSSION 28 87 NOMENCLATURE T : design temperature, °C C : corrosion allowance, mm Di : inside diameter of the vessel, mm Do : outside diameter of the vessel, mm Ri : inside radius of the vessel, mm Ro : outside radius of the vessel, mm S : maximum allowable stress, kg/cmA2 E : Joint efficiency, % T : required the thickness, mm tn : minimum thickness provided for the nozzle, mm P : design pressure, kg/cmA2 trn : selected thickness for the nozzle, mm fr : strength reduction factor Mt : moment at the skirt to head joint, kg-mm W : weight of the vessel H : height of center of gravity Fe : seismic coefficient N: Number of bolts Ab : area with in the bolt circles, mmA2 Cb : circumference of bolt circle, mm Ba : required area of one bolt, mm As : area within the skirt, mmA2 Cs : circumference on outer diameter of skirt, mm Dso outer diameter of the skirt, mm P : design pressure, kg/cmA2 Dsi: inside diameter of the skirt, mm Fb : safe bearing load on the concrete, kg/cm A2 I : width of the base plate, mm The equations may be written in the following forms t = PRi/(SE-0.6P) = Pro / (SE-0.4P) Where, t t = minimum required thickness of the shell exclusively of Corrosion allowance P= design pressure, or maximum an allowable working Pressure welded -joint efficiency 10
