Abstract
Una corriente de hidrocarburo que contiene azufre y compuestos de azufre se pone en contacto con una suspensión de agua de cal dolomítica y catalizador de ácido dibásico en un recipiente de reacción a fin de transferir el azufre y los compuestos de azufre del vapor de petróleo a la fase acuosa. Durante la eliminación de azufre, el ácido naflénico presente en el vapor de petróleo caliente se convierte en una fracción de nafta de alta calidad. En la fase acuosa, los compuestos de azufre reaccionan con la alcalinidad disponibles de la cal dolomítica y el ácido dibásico. Los productos de reacción a base de calcio o magnesio insoluble pueden entonces ser retirados de la fase acuosa a través del equipo convencional de concentración y separación de sólidos.A hydrocarbon stream containing sulfur and sulfur compounds is contacted with a suspension of dolomitic lime water and dibasic acid catalyst in a reaction vessel in order to transfer sulfur and sulfur compounds from the petroleum vapor to the aqueous phase. During sulfur removal, the naphlenic acid present in the hot petroleum vapor is converted to a high-quality naphtha fraction. In the aqueous phase, the sulfur compounds react with the available alkalinity of dolomitic lime and dibasic acid. The insoluble magnesium or calcium based reaction products can then be removed from the aqueous phase through conventional solids concentration and separation equipment.
