The wall thickness calculation follows ASME BPVC Section VIII Division 1 requirements for pressure vessel design. For cylindrical shells under internal pressure:
Where t is the minimum thickness, P is the design pressure, R is the inside radius, S is the allowable stress, and E is the joint efficiency.
Vessel capacity calculations determine the volume and weight of fluids in various vessel configurations. For horizontal cylindrical vessels:
Where V is the liquid volume, L is the length, R is the radius, and h is the liquid height.
Separator design involves calculating dimensions for two-phase and three-phase separators based on flow rates, fluid properties, and retention time requirements.
Where D is the diameter, Q is the gas flow rate, and V is the allowable gas velocity.
Head design calculations determine the thickness and dimensions for various pressure vessel head types including hemispherical, ellipsoidal, torispherical, and conical heads.
Where t is the head thickness, P is the design pressure, L is the crown radius, S is the allowable stress, and E is the joint efficiency.
