Изобретение относитс  к газовому анализу .This invention relates to gas analysis.

Известен способ концентрировани  газовых примесей из газовых потоков путем их селективной сорбции на адсорбенте с последующей десорбцией при нагревании.A known method of concentrating gas impurities from gas streams by selective sorption on an adsorbent, followed by desorption when heated.

Недостатком известного способа  вл етс  низкий коэффициент обогащени  примесей, ограниченный коэффициентом сорбции (коэффициентом Генри).The disadvantage of this method is the low enrichment factor of impurities, limited by the sorption coefficient (Henry coefficient).

С целью увеличени  коэффициента обогащени  предлагаетс  после насыщени  адсорбента снижать давление и последующую десорбцию примесей вести при поддержании этого давлени .In order to increase the enrichment factor, it is proposed, after saturation of the adsorbent, to reduce the pressure and the subsequent desorption of impurities while maintaining this pressure.

Процесс осуществл етс  следующим образом . Концентратор с сорбентом при нормальном давлении насыщают смесью, содержащей примесь концентрируемого вещества, а затем откачивают до давлени  меньше исходного. После откачки концентрируемое вещество перевод т диффузионным путем или потоком газа-носител  в анализатор.The process is as follows. A concentrator with a sorbent at normal pressure is saturated with a mixture containing an admixture of a concentrated substance, and then pumped to a pressure less than the original. After pumping, the concentrated substance is transferred by diffusion or a carrier gas stream to the analyzer.

Пример. Газовую смесь, содержащуюExample. Gas mixture containing

0,07% этилена в гелии, пропускают через концентратор с активным углем марки СКТ при нормальном давлении, откачивают концентратор до 0,8 мм рт. ст., устанавливают рабочее0.07% of ethylene in helium is passed through a SKT grade activated carbon concentrator at normal pressure, the concentrator is pumped out to 0.8 mm Hg. Art., set working

давление 1 мм рт. ст., перевод т этилен диффузионным путем в анализатор и определ ют степепь обогащени . После этого концентратор нагревают до 60°С и снова определ ют степень обогащени .pressure of 1 mm Hg. Art., diffusion of ethylene to an analyzer and determining the degree of enrichment. Thereafter, the concentrator is heated to 60 ° C and the degree of enrichment is again determined.

В первом случае, без нагревани , степень обогащени  равна 700, при коэффициенте Генри 420. Во втором случае, после нагревани , стенень обогащени  превышает 1000.In the first case, without heating, the degree of enrichment is 700, with a Henry coefficient of 420. In the second case, after heating, the wall of enrichment exceeds 1000.

Предмет изобретеии Subject of invention

Способ концентрировани  газовых примесей из газовых потоков путем их селективной сорбции на адсорбенте с последующей десорбцией при нагревании, отличающийс  тем, что, с целью увеличени  коэффициента обогащени , после насыщени  адсорбента давление снижают и последующую десорбцию примесей ведзт при поддержании этого давлени .A method for concentrating gas impurities from gas streams by selective sorption on an adsorbent followed by desorption when heated, characterized in that, in order to increase the enrichment factor, after saturation of the adsorbent, pressure is reduced and subsequent desorption of impurities is maintained while maintaining this pressure.
