Description

П р и м е р 1. В абсорбционную mr с пористой ппастиной, заполнентгую 90%- ным раствором серной кислоты до толшины барбота кного сло  60-70 мм при комнатной температуре со скоростью 0,1 м/сек пропускают паровоз ушн)гю смесь (ПБС), со- держашую 1ОО-2ОО стирола. Степень очистки газа от стирола составл ет 1 ОО%.PRI me R 1. Absorb mr with porous ppastina filled with 90% sulfuric acid to the thickness of the bubbling layer 60-70 mm at room temperature with a speed of 0.1 m / s steam locomotive is passed through) mixture ( PBS) containing 1OO-2OO styrene. The degree of gas purification from styrene is 1% OO.

Пример 2. При услови х, аналогичных примеру 1, осуществл ют абсорбцию стирола 9О%наым или 75%-ным растворами серной кислоты. Ниже приведена таблица, показывающа  эффективность степени очистки газа от стирола в зависимости от концентрации раствороб серной кислоты.Example 2. Under conditions similar to Example 1, styrene is absorbed with 9O% or 75% sulfuric acid solutions. Below is a table showing the effectiveness of the degree of gas purification from styrene, depending on the concentration of a solution of sulfuric acid.

Из таблицы видно, что при концентрации серной кислоты 80-90% степень очистки дос imraeT 90-100%, при использовании 75% HeS степень очистки равна 40%, в случае использовани  серной кислоты -9О% газь после очистки будут содержать0,1 мг/м паров серной кислоты. Формула изобретени  Способ очистки отход щих газов от сти рола путем абсорбции, отличающий с   тем, что, с целью поагшени  степени очистки и упрощени  процесса, в качестве абсорбента используют водный раствор серной кислоты.
