Abstract
Un procedimiento de coquificación retardada que comprende: (a) calentar una alimentación de residuo de petróleo, en una primera zona de calentamiento, a una temperatura que está por debajo de las temperaturas de coquificación pero a una temperatura en la que el residuo es un líquido bombeable; (b) conducir dicho residuo calentado a una segunda zona de calentamiento en donde éste es calentado a unas temperaturas de coquificación, (c) conducir dicho residuo de petróleo calentado desde dicha segunda zona de calentamiento hasta una zona de codificación en donde se recogen unos productos en forma de vapor por la parte superior y se forma un producto de coque esférico que sustancialmente es libremente fluyente; y (d) introducir en dicho residuo de petróleo de 300 a 3.000 wppm de por lo menos un aditivo polimérico que se selecciona entre un poli(oxietileno), un poli(oxipropileno), un copolímero de poli(oxietileno)-poli(oxipropileno), un etilendiamina alcohol tetra alcoxilado de un poli(oxietilen) alcohol, un etilendiamina alcohol tetra alcoxilado de un poli(oxipropilen) alcohol, un etilendiamina alcohol tetra alcoxilado de unos poli(oxipropilen)-poli(oxietilen) alcoholes, y que tiene un peso molecular de 1.000 hasta 30.000, en una cantidad que es eficaz para la formación de un coque esférico que sustancialmente es libremente fluyente, en donde dicho aditivo polimérico es introducido en dicho residuo de petróleo en un lugar situado corriente arriba de la segunda zona de calentamiento, entre dicha segunda zona de calentamiento y dicha zona de coquificación o en ambos lugares.A delayed coking process comprising: (a) heating a petroleum residue feed, in a first heating zone, to a temperature that is below coking temperatures but at a temperature where the residue is a liquid pumpable; (b) leading said heated residue to a second heating zone where it is heated to coking temperatures, (c) leading said heated petroleum residue from said second heating zone to a coding zone where products are collected in the form of vapor at the top and a spherical coke product is formed which is substantially free flowing; and (d) introducing into said petroleum residue from 300 to 3,000 wppm of at least one polymeric additive selected from a poly(oxyethylene), a poly(oxypropylene), a poly(oxyethylene)-poly(oxypropylene) copolymer , a tetra-alkoxylated ethylenediamine alcohol of a poly(oxyethylene) alcohol, a tetra-alkoxylated ethylenediamine alcohol of a poly(oxypropylene) alcohol, a tetra-alkoxylated ethylenediamine alcohol of poly(oxypropylene)-poly(oxyethylene) alcohols, and having a weight molecular weight of 1,000 to 30,000, in an amount that is effective for the formation of a substantially free-flowing spherical coke, wherein said polymeric additive is introduced into said petroleum residue at a location upstream of the second heating zone, between said second heating zone and said coking zone or at both locations.
