Abstract

"MéTODO PARA REDUZIR ESPUMA EM UM FRACIONADOR PRIMáRIO". A presente invenção refere-se a inclusão de métodos para melhorar os parâmetros operacionais em fracionadores primários que estão experimentando eficácias de operação diminuídas devido aos depósitos de espécies hidrocarbonetos polimerizadas. A invenção compreende a etapa de adicionar uma quantidade de redução de espuma de uma composição de redução de espuma no fracionador primário. Uma redução na espumação é obtida, assim a eficácia operacional do processo é melhorada com base nos parâmetros de operação incluindo, mas não limitados a relação de contato líquido-gás, temperatura de topo de produto, diferenciais de pressão, ponto final de gasolina ou combinações dos mesmos.
