Detalhamento de planta de gaseificação em leito fluidizado circulante: montagem, integração dos sistemas da usina termoquímica experimental da UFU

Abstract

The growing demand for technologies capable of promoting the energy recovery of waste has driven the development of gasification systems as a sustainable alternative for energy generation. In this context, the present study aimed to monitor and describe the implementation and commissioning of a pilot-scale circulating fluidized bed gasification plant designed for syngas production from Refuse-Derived Fuel (RDF). The adopted methodology consisted of monitoring the stages of mechanical assembly, hydraulic, electrical, and instrumentation installations, system integration, and commissioning tests. During the implementation phase, the reactor, cyclone, heat exchangers, gas cleaning system, hydraulic circuit, electrical infrastructure, automation system, and auxiliary equipment were installed, in addition to the interconnection of all process units. Cold commissioning tests were carried out to verify system tightness, equipment operation, control device parameterization, and the correction of nonconformities identified during the implementation process. The results demonstrated that proper assembly planning and effective commissioning were essential to ensure system integration, operational safety, and plant readiness for subsequent operational stages. This study contributes to the technical documentation of gasification plant implementation and highlights the importance of commissioning as an essential step in ensuring the operational reliability of thermochemical systems.
