in this paper, mostly introduce to desulfurize method of sulphate form, pass in reverse floatation may hold sulfur of iron concentrate drop to 0.13%, sulfur get ride of ratio became 93.43%.
at present, wet flue gas desulphurization technology is the best mature technology used to control the content of so2, and it is also a primary way commended to desulfurize in the future.
a large amount of ash and slag were generated when petroleum coke that contained sulfur was fired by circulation fluidized-bed (cfb) boiler to desulfurize by adding limestone.
special solvents can be used to decarbonize and desulfurize waste catalysts to replace the high-temperature roasting pretreatment process.
可以采用特殊的溶剂对废催化剂进行脱碳和脱硫预处理,以代替高温焙烧预处理。
through using spraying magnesium grain into iron to desulfurize and pushing out the top slag, the sulfur content in the iron was decreased.
采用单喷颗粒镁铁水脱硫与扒渣工艺,改善了转炉冶炼原料铁水条件。
although traditional hydro-desulfurization (hds) can desulfurize gasoline deeply, but it can also lead to octane reduction, more hydrogen consumption and equipment investment.
传统的加氢脱硫技术虽然可使汽油深度脱硫,但同时会导致辛烷值明显下降,增加氢耗及设备投资。
a management act for dedust and desulfurize of dry-damp two-step combined method was brought forward when the efficiency of smoke dedust and desulfurize were 98% and 80%.
