Relatório de viagem técnica.

Motivação: Participação na primeira conferência sobre Oxi-combustão.

Destino: Cottbus – República Federal de Alemanha.

Data de saída: 05/09/2009

Data de retorno: 13/09/2009

Eng. Mec. Diego Rubén Schmeda López.

O congresso foi organizado pela Agencia Internacional de Energia, no seu programa de

pesquisa e desenvolvimento sobre gases de efeito estufa (IEA – Greenhouse Gas R&D

Programme).

O processo de oxi-combustão consiste na queima do combustível em uma atmosfera rica em

oxigênio, até um máximo de cerca de 30%, completado por gás carbônico aquecido, desviado

dos gases de exaustão do sistema de queima. Com isto a temperatura da queima é mais

elevada permitindo seu acoplamento a geradores de vapor supercríticos. Dada a ausência de

nitrogênio na mistura comburente, não há formação de NOx e a os níveis de SOx são

reduzidos. Como produto de combustão se obtém basicamente CO2 e vapor de água, existindo

outros compostos ácidos em quantidades mínimas.

Impressões gerais do congresso.

A tecnologia de oxi-combustão é ainda uma técnica em desenvolvimento, tendo ainda muitos

problemas para serem resolvidos, como por exemplo: a obtenção mais barata de oxigênio e a

solução de problemas relativos à região de queima com grande infuência de radiação

térmica.. Materiais para altas temperaturas também devem ser desenvolvidos. Os

organizadores apresentam esta tecnologia como uma possibilidade viável de sequestro de CO2

em curto tempo, a pessar da planta piloto ainda não mostrar resultados satisfatórios.

Processos de combustão com oxigênio puro não foram abordados no congresso devido às

dificuldades técnicas e tecnológicas de seu desenvolvimento.

Ficam ainda pendentes questões técnicas e econômicas ligadas ao transporte e

armazenamento do CO2, bem como a adaptabilidade do processo a diferentes tipos de carvão.

Empresas de grande porte como a Vattenfall, Air Liquide, Air products, Alstom e Linde,

apostam fortemente nesta tecnologia. Outras empresas como Schlumberger, Metso, etc.

também estiveram presentes.

Aparentemente a tecnologia sería aplicável à realidade brasileira porém uma avaliação

técnico-econômica deve ser feita. Tanto na Europa como aqui, resta saber o que fazer com

com o CO2 sequestrado, locais e tecnologias para armazenagem.

Visitas Técnicas Realizadas.
