    • A process is disclosed for purifying raw gas produced by the gasification of solid fuels under superatmospheric pressure by treatment with gasifying agents containing water vapor and free oxygen. The raw gas contains dust and hydrocarbons and is at a temperature of 400.degree.-700.degree. C as it leaves the gas producer. The raw gas is purified by spraying in at least two scrubbing stages with virtually dustfree, highly dispersed scrubbing water at temperatures of 160.degree.-300.degree. C. In this manner, the gas is cooled to a temperature that is 0.degree.-20 C above the scrubbing water temperature and is saturated with water vapor in the scrubbing stages. Thereafter, the gas is subjected to centrifugal force to increase the relative velocity between gas and water droplets. The scrubbing water which contains dust and tar is withdrawn from each scrubbing stage. For the first scrubbing stage a cyclone-type scrubber can be used and for the second scrubbing stage a radial flow-type scrubber or a Venturi-type scrubber can be used.
    • 公开了一种通过用含有水蒸气和游离氧的气化剂处理来净化在超大气压下通过固体燃料气化生产的原料气的方法。 原料气体含有灰尘和碳氢化合物,并在离开燃气生产者时处于400〜700℃的温度。 原料气体在至少两个洗涤阶段通过喷雾纯化,实际上无灰尘,高度分散的洗涤水在160-300℃的温度下。以这种方式,将气体冷却至0℃-20℃以上的温度 洗涤水温度,并在洗涤阶段用水蒸汽饱和。 此后,气体经受离心力以增加气体和水滴之间的相对速度。 从每个洗涤阶段抽出含有灰尘和焦油的洗涤水。 对于第一洗涤阶段,可以使用旋风式洗涤器,并且对于第二洗涤阶段,可以使用径向流式洗涤器或文丘里型洗涤器。
