Abstract
1. Способ термического обезвоживания нефтесодержащих отходов нагреванием до текучего состояния, испарением влаги при 100-150°С и перемешиванием в присутствии добавки поверхностно-активного вещества, отличающийся тем, что перемешивание осуществляют путем продувания нефтесодержащих отходов инертным газом, который выбирают из азота, аргона или двуокиси углерода; при этом вводят добавку поверхностно-активного вещества в поток инертного газа, а в качестве поверхностно-активного вещества используют продукт кислотного гидролиза соапстока - побочного продукта рафинации растительных масел, с кислотным числом 100-145 мг КОН/г в количестве 5·10-8·10массовых частей на одну массовую часть нефтесодержащего отхода.2. Способ по п.1, отличающийся тем, что в качестве обводненных нефтесодержащих отходов используют: некондиционные битумы, битуминозные пески, высоковязкие нефти, асфальто-смоло-парафиновые отложения.1. The method of thermal dehydration of oily waste by heating to a fluid state, evaporation of moisture at 100-150 ° C and stirring in the presence of a surfactant additive, characterized in that the mixing is carried out by blowing oily waste with an inert gas, which is selected from nitrogen, argon or carbon dioxide; in this case, a surfactant additive is introduced into the inert gas stream, and the product of acid hydrolysis of soap stock, a by-product of the refining of vegetable oils, with an acid number of 100-145 mg KOH / g in an amount of 5 · 10-8 · is used as a surfactant 10 mass parts per mass part of oily waste. 2. The method according to claim 1, characterized in that as watered oily waste use: substandard bitumen, tar sands, high viscosity oils, asphalt-resin-paraffin deposits.
