Pressure Vessel and Chemical Plant

Design and Analysis of Pressure Vessel Subjected to Pressure-temperature Variation (TECHNICAL NOTE)

Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...

Analytical and Numerical Investigation of FGM Pressure Vessel Reinforced by Laminated Composite Materials

In this research, the analytical and numerical investigation of a cylindrical shell made of functionally graded materials (FGMs) reinforced by laminated composite subjected to internal pressure is presented. Using the infinitesimal theory of elasticity, the analytical solution of stress and strain in vessels made of FGMs is studied first. It is assumed that the elasticity modulus follows a powe...

Reactor Pressure Vessel Embrittlement—i

Vessel growth and collapsible pressure-area relationship.

The role that the pattern of vessel wall growth plays in determining pressure-lumen area (P-A) and pressure-compliance curves was examined. A P-A vessel model was developed that encompasses the complete range of pressure, including negative values, and accounts for size given the fixed length, nonlinear elastic wall properties, constant wall area, and collapse. Data were obtained from excised c...

Evaluation plant properties and chemical composition of Lathyrus rotundifolius

Background and objectives: Plant properties and forage value of lathyrus rotundifolius, was assessed in Namin rangeland. Persian everlasting pea is belonged to legume family and it is a wild plant that grow at Heyran and Fandoghlo region in Ardebile province of Iran. Based on local residents experience, they consider the forage of this plant as one of the best forage and collect it for livestoc...
