Diseño de un recipiente de presión vertical con capacidad de 18.5 M3 para endulzamiento de GLP con aminas mediante análisis de elementos finitos

Abstract

In the next study, the design of a vertical pressure vessel with a capacity of 18.5 m3 for LPG sweetening with amines is developed using the finite element analysis, initially, and the national and international standards that govern the design of the vessel are established, with which the initial conditions such as capacity, internal radius, design pressure and the necessary nozzles were found. Applying the ASME section VIII division 1, the commercial thicknesses of 0.625 in for the body and 0.50 in for the heads, the safety factor of 5.55 in the body and 4.48 in the head were calculated. The required thickness for each nozzle was determined according to UG45, the lesser available thickness, and the required area according to UG-37. Using the finite element analysis, the results found in the analytical calculation were validated, obtaining a safety factor in the body of 3.07, in the heads 3.66, and in the vessel 3.80. The results obtained by the two methods exceed 3.5, which is the safety factor determined by the standard, which certifies a safe design of the vessel.
