    • Anhydrous liquid sulfur dioxide is recovered from environmentally unsuitable vapor or liquid streams comprising water, sulfur dioxide and carbon dioxide. The vapor streams are fed into an absorption zone and contacted with a lean liquid water stream. A resulting sulfur dioxide rich water stream is passed into a first fractionation column utilized in part as the stripper column which produces the lean water stream. A sidecut stream removed above the feed point is passed into a second fractionation column, and the overhead vapor of the first column is subjected to two stages of partial condensation to aid carbon dioxide rejection. Anhydrous sulfur dioxide is removed as a liquid sidecut of the second column, and the net overhead vapor of the second column is preferably passed into the overhead system of the first column after a partial condensation.
    • 从包括水,二氧化硫和二氧化碳的环境不合适的蒸汽或液体流中回收无水液体二氧化硫。 将蒸气流送入吸收区并与贫液体水流接触。 得到的富含二氧化硫的水流被送入第一分馏塔,部分作为产生贫水流的汽提塔。 在进料点上方除去的侧流被送入第二分馏塔,第一塔的塔顶蒸气进行两个阶段的部分冷凝以帮助排除二氧化碳。 作为第二塔的液体单元除去无水二氧化硫,第二塔的净顶空蒸气优选在部分冷凝后进入第一塔的塔顶系统。

    • A mixture of a hydrocarbon-selective solvent -- e.g. isobutane -- and deasphalted oil is separated in a two-stage hot-separator system at progressively higher temperatures and substantially the same pressure. Resulting vaporous phases are subjected to a cold-flash separation at a lower pressure and a considerably lower temperature. The initial hot separation, in the two-stage system, is effected at a temperature from about 1.0.degree. F. to about 25.degree. F. above the critical temperature of the solvent; the second is conducted at a temperature about 30.degree. F. to about 130.degree. F. above that in the initial hot-separation. This technique is especially advantageous when integrated into a catalytic slurry process for the conversion of metal- and asphaltene-containing hydrocarbonaceous black oils.
    • 烃选择性溶剂的混合物。 异丁烷和脱沥青油在逐步升高的温度和基本相同的压力下在两级热分离器系统中分离。 所得气相在较低压力和相当低的温度下进行冷闪分离。 在两级系统中的初始热分离在高于溶剂的临界温度约1.0°F至约25°F的温度下进行; 第二次在初始热分离中温度约30°F至约130°F的温度下进行。 当整合到用于转化含金属和含沥青质的含烃黑油的催化淤浆法时,该技术是特别有利的。
