Diseño mecánico de una bota de gas de 5000 GLS

Abstract

Because the primary fluid from oil Wells is a mixture of water, sand, oil and gas; the midstream HYDROCARBON plant requires a specific number of separation stages, and therefore, pressure vessels designed for this purpose. While there is a great demand for separators as well as design procedures, this research paper aims to provide the designer with an updated and practice design methodology for the container of the last stage of separation (gas boot); as well as, BOM, building plans, manufacturing costs, calculation sample for elements unrelated to the ASME code, and technical criteria results of a global design based on national and international standards and codes (ASME, NEC 2014, UBC 97, etc. .). Parameters of input fluid such as: pressure, temperature, gas-oil ratio were analyzed (GOR), with which the hydraulic design was made obtaining diameters, heights and the fluid retention time. Subsequently the mechanical design of the constituent elements of the separator was conducted; parts such as cylinder, heads, reinforcing ring and entrances, were based on the ASME code, and were supplemented by the combined loads criteria proposed by Bergman. Finally, the bill of materials, construction drawings and cost analysis was developed. The results of the proposed methodology allow to contribute to the metal-mechanical domestic sector and concludes that external pressure rules the cylinder body design, the lower MAWP rulers the camera as well as the highest MDMT. Reinforcement rings act as bracing to prevent sagging; therefore there is a diminution of body section to external pressure.
