The technique process and system structure of liquidcolumn injecting desulphurization used in Nanning Smeltery

Guangxi Province

has been presented

giving out design parameters

initial capital investment

and operating cost. An elementary analysis of occurred problems in commissioning test

such as clogging

corrosion

and dehydrolysis etc.

have been carried out

and relevant recommendations being given. Through monitoring appraisal of The State Environmental Protection Bureau

it is confirmed the SO

2

concentration at inlet and outlet is 15

000 μL/L and 300 μL/L respectively. Under conditions of high concentration and largeamplitude variation

the efficiency of desulphurization is over 95%; the capital investment and operating cost of the said desulphurization system to be lower

and the operation of said system keeping basically in normality.
