Tanques de armazenamento cilindricos e atmosféricos: otimização de projeto considerando critérios ambientais

Abstract

Atmospheric tank projects cover a wide range of technical characteristics, ranging from their purpose, according to the regulatory framework, the type of product stored, the technical aspects of the tank to serve this storage with structural safety, and finally, the devices and technical resources to make the equipment financially and economically viable and sustainable. As a basis for criteria for this assessment, the correct regulatory framework for each type of tank, based on its application, and the correct selection of material for its performance and life expectancy, were addressed. Performance improvement criteria were also evaluated, such as the proper sizing of the tank inlet, outlet, and vent nozzles, the use of sensors and devices, and equipment to avoid overpressure or vacuum, and the use of internal floating roofs. In addition, environmental criteria were also presented, such as the correct selection of tank colors and the assessment of their area of ​​incidence of solar radiation. The list of criteria and technical, performance, and environmental details can be further complemented and developed with other characteristics of the tanks, and the objective of this article was to evaluate the main parameters of analysis to guide the developer of the tank project to execute it seeking to optimize technical data with immediate execution and operating costs and the environmental impact of project decisions for welded vertical cylindrical atmospheric storage tanks.
