Diseño conceptual de una planta piloto de galvanizado por electrodeposición en sustratos metálicos en la Empresa HRS S.A.S.

Abstract

HRS SAS is a company located in Bogotá, dedicated to manufacture of specialized chemicals in the area of both hot and cold galvanizing, where the necessary supplies are produced to maintain the different optimal metal baths as well as degreasing baths, which They are necessary to prepare the piece before the coatings, however, there is no plant that performs the coating operations with the baths provided by the company, in order to test and maintain their quality, providing security and support. of the quality of the products to its clients. Therefore, in this work, a pilot plant design model is exposed for the galvanizing process in metallic raw materials of a decorative type, counting on the basic operations of a galvanizing such as copper flash, alkaline copper, nickel and bright acid copper. In the dimensioning and characterization process, it was established that the bath tanks must have measures of 30 cm long, 24 cm wide and 35 cm high, made of polypropylene to keep baths safe in the working temperature range. They made the necessary calculations to determine the powers and heats of each operation, and a distribution of the plant was made to optimize space and reduce risks and spills. Taking into account the number of equipment, their specifications and the number of stages that the part must go through in the galvanizing, the economic analysis was finally carried out in order to evaluate the necessary costs for its installation, obtaining so the cost to install the plant is $68.350.254 and an analysis of the costs of services that would take to operate it in a year for which it was estimated at $3,339,169, finally giving a total cost of investment and operation of $ 72,000,000.
