Ações para redução no consumo de gás natural em um Processo litográfico

Abstract

In a current scenario with a market and a policy of increasingly competitive sales prices, the companies have little influence on their selling price, which is often defined by the market. In this sense, the practice of cost management in companies has increasingly demonstrated its essentiality and objectivity, providing up-to-date information and important concepts that help decision making in companies in general. The following work was developed through a study in the field of Lithography in a Metalgraphic. The industry in this study produces lithographed cans, plastic buckets and metal crown caps. The cans are manufactured in the most diverse formats, sizes and coatings and are intended for the packaging of chemicals, insecticides, petroleum products, paints, varnishes and food. Inserted in the process of manufacturing all these items, there is the steel lithography, which consists of printing on the steel, by means of a press, a writing or a drawing executed with ink. After printing, the sheet passes through an oven, in which the volatiles of the paint and / or varnish are evaporated to cure the steel sheet, the volatiles leave the oven to a incinerator, in order to avoid contamination of the environment. The ovens and incinerators use natural gas for the generation of heat and this cost is directly linked to the final value of the finished product. Approximately 99% of the natural gas consumption of the plant occurs in lithography, which is the area where the study was applied. Thus, the actions generated from this work are: Production scheduling, Machine wear analysis, quantification of losses in pipes without thermal coating and scaling of incinerator insufflation. These actions, when implemented, will promote a reduction in the consumption of natural gas that saves up to R$ 57.866,14 per month.
