Abstract
1. Способ очистки органоминеральных водных растворов производства капролактама, включающий твердофазную экстракцию органических веществ, регенерацию адсорбента и повторное использование в технологическом процессе очищенных водных растворов, регенерированного адсорбента и выделенных при регенерации адсорбента органических веществ, отличающийся тем, что твердофазную экстракцию органических веществ проводят последовательно в две стадии сначала с использованием микропористого сверхсшитого полистирольного адсорбента, например, MN 270, затем с использованием сверхсшитого полистирольного адсорбента, имеющего как узкие, так и широкие поры, например, MN 202, а регенерацию каждого адсорбента осуществляют путем контакта с водным раствором изопропилового спирта, причем процессы твердофазной экстракции и регенерации проводят при интенсивном перемешивании адсорбента. ! 2. Устройство для очистки органоминеральных водных растворов производства капролактама, содержащее две последовательно соединенные емкости с подводящими и отводящими линиями и расположенным в каждой из емкостей адсорбентом с различными свойствами, отличающееся тем, что внутри каждой емкости установлены горизонтальные перфорированные тарелки для адсорбента, которые соединены с электроприводом с возможностью совершения возвратно-поступательных перемещений.1. The method of purification of organomineral aqueous solutions of caprolactam production, including solid-phase extraction of organic substances, regeneration of the adsorbent and reuse in the process of purified aqueous solutions, the regenerated adsorbent and the organic substances extracted during the regeneration of the adsorbent, characterized in that the solid-phase extraction of organic substances is carried out sequentially in two stage first using microporous hypercrosslinked polystyrene adsorbent, for example, MN 270 then using a hypercrosslinked polystyrene adsorbent having both narrow and wide pores, for example, MN 202, and the regeneration of each adsorbent is carried out by contact with an aqueous solution of isopropyl alcohol, and the solid-phase extraction and regeneration processes are carried out with vigorous stirring of the adsorbent. ! 2. A device for cleaning organomineral aqueous solutions of caprolactam production, containing two series-connected containers with inlet and outlet lines and an adsorbent located in each container with different properties, characterized in that horizontal containers are installed inside each container for adsorbent plates, which are connected to the electric drive with the possibility of reciprocating movements.
