COKE OVEN GAS TREATING

 

Processing of acid gas compounds in coke oven gas is commonly coupled to a modified Claus sulfur recovery unit. For these applications, Porocel offers our complete range of sulfur recovery catalysts in addition to our specialty HCN conversion catalyst, HCN-100. With HCN-100, HCN conversion is achieved in a separate reaction vessel, downstream of the vacuum carbonate or amine treating process, but upstream of the SRU reaction furnace. Typically, two HCN reactors are installed in parallel so that one may be on-line while the other is in standby mode.

 

HCN-100 is a promoted alumina catalyst which facilitates the conversion of HCN via the following reactions.

HCN + 2 H2S + 1/2 O2 → CS2 + H2O + NH3

HCN + H2O → NH3 +CO
