The assimilation and start-up of a new plant for the manufacture of sulfuric acid is a useful case study for the conduct of the assimilation of new technologies, this is a risky activity. The objective of the present research is to establish a procedure for the assimilation and adaptation of the necessary technology for the manufacture of sulfuric acid that makes possible the safe and efficient conduct of the technical start-up of a new industrial capacity and its normal operation. The conceptual bases and a heuristic procedure were elaborated for the technological assimilation in concentrated sulfuric acid production facilities based on the double contact production method from elemental solid sulfur. For this purpose, the logical integration of the process systems was taken into account, as well as those established in the literature for the development, evaluation and assimilation of ...

The industrial process for the production of mayonnaise is associated with the disposal of eggshells as solid waste. The sauces and dressings factory "Los atrevidos" is interested in valorizing this waste by incorporating a technological system capable of treating its waste and minimizing its environmental impact through process intensification and cleaner production. The present research aims to design a technological-productive system for the treatment of residual eggshells to obtain animal feed supplement rich in calcium carbonate, with emphasis on the design of a batch tray dryer. Material balances were developed to quantify the waste load to be treated, the necessary inputs and the projection of the technological production scheme. The production plant was designed to handle up to 500 kg/day of eggshells; the main production stages are: treatment of raw materials, drying, milling an...
