Abstract

1. СПОСОБ ПЕРЕРАБОТКИ ГАЗОВ, СОДЕРЖАЩИХ ФТОРИСТЫЙ ВОДОРОД с примесью четырехфтористого кремни  и фосфатной пыли, путем абсорбции водными' растворами, содержащими соединени  аммони , отличающий- с   тем, что, с целью упрощени  технологического процесса, в абсорбирующий раствор предварительно ввод т фтористый натрий.2. Способ по п. 1, о т л и ч а - ю щ и и с   тем, что весовое соотношение между фтористым натрием и соединением аммони  в абсорбирующем растворе не ниже 1:5.1. METHOD FOR PROCESSING GASES CONTAINING FLUOROUS HYDROGEN with admixture of silicon tetrafluoride and phosphate dust, by absorption with aqueous solutions containing ammonium compounds, so that, in order to simplify the process, precursor sodium fluoride is introduced into the absorbent solution . The method according to claim 1, about tl and h a - y i and so that the weight ratio between sodium fluoride and ammonium compound in the absorbing solution is not less than 1: 5.
