Изобретение касаетс  очистки газов в частности реакционных газов производства хлористого винила, от металлической ртути и сулемы .The invention relates to the purification of gases, in particular of reaction gases produced from vinyl chloride, from metallic mercury and mercuric chloride.

Известен способ очистки газов от паров металлической ртути путем абсорбции раствором хлорного железа в смеси с хлористым водородом . При этом степень очистки газа от ртути составл ет 99,2-99,5%.A known method of gas purification from metal mercury vapor by absorption by a solution of ferric chloride in a mixture with hydrogen chloride. The degree of gas purification from mercury is 99.2-99.5%.

Но по этому способу степень очистки газа недостаточно высока и, кроме того, большой расход хлорного железа.But according to this method, the degree of gas purification is not high enough and, in addition, high consumption of ferric chloride.

Предложенный способ отличаетс  тем, что в раствор ввод т сулему в количестве 1- 10 г/л, что приводит к повышению степени очистки до 99,95% и уменьшению расхода хлорного железа за счет использовани  последнего с концентрацией в поглотительном растворе до 10 г/л.The proposed method is characterized in that sublimate in the amount of 1-10 g / l is introduced into the solution, which leads to an increase in the degree of purification to 99.95% and a decrease in the consumption of ferric chloride by using the latter with a concentration in the absorption solution to 10 g / l .

Пример. Насыщенный парами ртути 20 мг/м газ подают в стекл нную колонку с насадкой, заполненной сол нокислым раствором хлорного железа (25 мл) с концентрацией 50, 30 и 10 г/л и добавкой сулемы 0; 0,5; 1; 10 г/л со скоростью 2 л/мин. Содержание ртути в очищенном газе ;0,01 мг/м. Степень очистки газа от ртути составл ет до 99,95%.Example. A 20 mg / m gas saturated with mercury vapor is fed to a glass column with a nozzle filled with a hydrochloric acid solution of ferric chloride (25 ml) with a concentration of 50, 30 and 10 g / l and the addition of mercuric chloride 0; 0.5; one; 10 g / l with a speed of 2 l / min. The mercury content in the purified gas is 0.01 mg / m. The degree of gas purification from mercury is up to 99.95%.

В таблице привод тс  данные о степени очистки газа от ртути при введении сулемы.The table provides data on the degree of gas purification from mercury upon the introduction of mercuric chloride.
