The ESO was carried out at Companhia Alcoolquímica Nacional - Alcoolquímica of the JB Group, located at Engenho Cachoeirinha, s / n, in the Rural Zone, Vitória de Santo Antão - PE. Companhia Alcoolquímica Nacional is a large sugar and alcohol industry and is currently responsible for the production of alcohol, spirits, sugar, carbon dioxide and electricity, which has been operating in the Northeast and Southeast regions, with the intention of expanding to other regions and abroad . The stage was carried out in the industrial production, in the distillery area of the Plant, in the stage of alcoholic fermentation, from 03/12/2019 to 05/21/2019, totaling a workload of 300 hours. The work was composed of two stages, beginning with the knowledge of the whole chain of the production process of the final products of the company, then the study and determination of the kinetic parameters, besides the mathematical modeling and simulation able to describe the stage of alcoholic fermentation. From the collection of data to the analyzes carried out on the cited samples, the correct adjustments of the model were made, through the substrate, cell and product balance equations, as well as in the six kinetic models collected from the literature. Thus, it was possible to adjust a mathematical model capable of simulating the alcoholic fermentation process of the company, in terms of substrate concentration and final product, obtaining a mean margin of error between the stages of 38.32% and 4.76%, respectively. However, considering that some kinetic models used do not take into account the concentration of cells, except for one, it was not possible to predict the concentration of cells throughout the alcoholic fermentation process. Due to the high competitiveness in the market, the companies have been looking for new studies of the processes in search of continuous improvements and therefore better to know the process demanding greater productivity and means that provide the gain of offer of the product to be commercialized.
Pernambuco forjado no açúcar: marcas e desdobramentos dos processos históricos, socioeconômicos e culturais da civilização do açúcar nas relações de trabalho e qualidade de vida dos trabalhadores do corte da cana

The so-called "sugar civilization" installed with the monoculture of sugarcane, mills and the entire complex destined to the processing of sugarcane during colonial Brazil, left deep marks on the socioeconomic and cultural fabric of Brazil, especially in the states and municipalities from northeast. Even today it is possible to identify the marks that this exploratory process in the labor relations and quality of life of rural workers rooted in the oppression and exploitation of labor. And being the cradle of Portuguese colonization and an exponent of the sugar agro-export center for a long historical period, Pernambuco, more specifically, the forest zone or the sugarcane zone, aroused the reason for this work, which has the general objective of carrying out a survey bibliographic of studies, researches and other forms of production of knowledge about the sugar civilization in the historical, socioeconomic and cultural processes, as well as its marks and consequences in the work relations and quality of life of workers in the sugarcane cut in the Pernambuco forest zone. For the study of literature review, at a time of restriction to public libraries due to the covid-19 pandemic, the resource of online research was used in platforms that offer virtual libraries with free access, being a determining factor for conducting the research. The study allowed us to observe that the sugar civilization left its marks and its consequences directly impact the work relationships and quality of life of rural workers in the sugarcane cut, related to land inequality, devastation of the Atlantic forest, poor remuneration, exploitation of labor, food insecurity, child labor, sexual division of labor and racial oppression.
