Análise da validação de um projeto de sistema de aquecimento de água em uma planta fabril

Abstract

In the pesticide industries, for the finished product to comply with quality standards, the production process must be safe and free from microbiological and chemical contamination. That way, those chemical industries must present cross-contamination prevention policies, then several points can be taken into accounts such as organization, cleaning, production flow, maintenance of facilities and equipment, standards-based activities and cleaning procedures. The decontamination and disinfection process of the manufacturing units is an important step in the production process. At this stage, quality standards need to be attended to avoid a possible contamination, then hot water can be helpful to reduce microbiological contamination. Keeping that in mind, this project aims to carry out a case study through analysis of the validation of a water heating system installation to the concentrated solution manufacturing plant of insecticide products. For this, a microbiological analysis of 4 water samples from a system implemented in the herbicide plant was carried out, before and after the heated water from the company (treated) and from the concessionaire (untreated), and no colony bacteria growth was observed. After that, the project was divided into four phases: 1ª) Planning, in which the project planning documentation was requested, reviewed and approved; 2ª) Acquisition, which consisted of analyzing budgets and approving the acquisition of equipment; 3ª) Detailing, in this step, the analysis and approval of the system flowchart, component sizing, and both 2D and 3D mechanical design were presented; 4ª) Execution, which the scope of the manufacturing, assembly, positioning and installation process is shown by the contractor; and 5ª) Closing, with the commissioned equipment. Demonstrations of the project plans and installation flowchart were made in order to present the necessary components for understanding, allowing the perception of the project as a whole, so that, after the feasibility analysis of the project, the equipment was manufactured and subsequently installed. Thus, the validation proved to be efficient and achievable, therefore, the heating system proposed for the study proved to be consistent and viable for use for the microbiological reduction in concentrated solution insecticide product tanks.
