Abstract

"PROCESSO PARA A REDUçãO DA QUANTIDADE DE áCIDOS CARBOXìLICOS EM CORRENTES DE PETRóLEO". A invenção compreende um processo para a redução da quantidade de ácidos carboxílicos em correntes de petróleo compreendendo as etapas de (a) adição à referida corrente de petróleo de um agente catalítico que compreende um composto solúvel em óleo ou dispersível em óleo de um metal selecionado do grupo consistindo do grupo de metais VB, VIB, VIIB e VIII, onde a quantidade de metal na referida corrente de petróleo é de pelo menos cerca de 5 ppmp, (b) aquecimento da referida corrente de petróleo com o referido agente catalítico em um reator a uma temperatura de cerca de 400 a cerca de 800 F (cerca de 204,44 até cerca de 426,67 C) e uma pressão ao redor da atmosférica a cerca de 1000 psig (cerca de 6996,33 kPa) na ausência substancial de hidrogênio, e (c) lavagem do reator contendo a referida corrente de petróleo e o referido agente catalítico com um gás inerte para manter a pressão parcial combinada d'água e do dióxido de carbono abaixo de 50 psia (344,75 kPa)."PROCESS FOR REDUCING THE QUANTITY OF CARBOXYLIC ACIDS IN OIL CHAINS". The invention comprises a process for reducing the amount of carboxylic acids in petroleum streams comprising the steps of (a) adding to said petroleum stream a catalytic agent comprising an oil-soluble or oil-dispersible compound of a metal selected from the group consisting of the metal group VB, VIB, VIIB and VIII, where the amount of metal in said oil stream is at least about 5 ppmp, (b) heating said oil stream with said catalytic agent in a reactor at a temperature of about 400 to about 800 F (about 204.44 to about 426.67 C) and a pressure around atmospheric at about 1000 psig (about 6996.33 kPa) in the substantial absence of hydrogen, and (c) washing the reactor containing said oil stream and said catalytic agent with an inert gas to maintain the combined partial pressure of water and carbon dioxide below 50 psia (344.75 kPa).
