Abstract
In treating a liquid with an immiscible liquid of different p specific gravity, the liquids are caused to flow in opposite directions through a series of mixing vessels without intermediate separation, the vessels being connected by inclined passages or channels in which the lighter liquid flows upwardly and the heavier liquid downwardly. As shown, three mixing vessels A, B, C are provided, each having a pipe l through which air is blown to agitate the liquid; mechanical stirrers may also be <PICT:0393527/IV/1> arranged in the vessels. The vessels are connected by inclined pipes b, c, and inclined overflow pipes a, d are also provided. The operation of the apparatus is described with reference to the washing of nitroglycerine with water or an alkaline solution. The whole apparatus is first filled with washing liquid up to the level of the overflow g, the valve f being closed. Washing liquid is then continuously run in through the pipe w or w<1>, and nitroglycerine through the pipe n or n<1> and the contents of the vessels are agitated. In the pipes a .. d, where no agitating means are present, the nitroglycerine flows downwardly and the washing liquid upwardly, with the result that used washing liquid flows out continuously at g. The valve f is opened when sufficient nitroglycerine has accumulated at s, and the nitroglycerine then withdrawn at e. Water may be supplied to the vessel A and alkali added in the vessel B. Means for heating or cooling the vessels may be provided. The apparatus may be used also for washing other nitroesters or nitro compounds, or for nitrating benzene and other hydrocarbons.ALSO:<PICT:0393527/III/1> In treating a liquid with an immiscible liquid of different specific gravity, the liquids are caused to flow in opposite directions through a series of mixing vessels without intermediate separation, the vessels being connected by inclined passages or channels in which the lighter liquid flows upwardly and the heavier liquid downwardly.

The valve f is opened when sufficient notroglycerine has accumulated at s, and the nitroglycerine then withdrawn at e. Water may be supplied to the vessel A and alkali added in the vessel B. Means for heating or cooling the vessels may be provided. The apparatus may be used also for washing other nitroesters or nitro compounds, for nitrating benzene and other hydrocarbons, and for refining petroleum with acids.
