The sulfur is convent to H2S in coal gas. And then convent to S2O as a pollution factor after burning.
At the same time, the sulfur content in coal gas is too high, for heating the work piece (such as steel billet
and mechanical parts ) will occur the phenomenon of sulfurizing, affect the performance of the material.Used
for coal producer gas in China are mostly low sulphur, sulphur content below 1%, such as Datong coal sulfur
content below 0.5%, after gasification into hydrogen sulfide formed in the gas at about 1 ~ 2 g/m3or so.
According to the requirements of a factory producing all kinds of alloy steel has not yet proposed as the
hydrogen sulfide content in the gas affect the quality of the steel, in other industries such as machinery
industry also did not put forward this problem, by practice, so that can not further in used as industrial
fuel gas desulfurization.
Now as a fuel gas desulfurization devices are also in the gas station, such as sichuan qianwei porcelain
factory is desulfurization tower, the same production line, similar products of Shanghai tai ceramics co.,
LTD., no desulfurization device, product quality is still very good.But in recent years, as a result of floor
tile of wall of building materials used, and the development of the mouth with ceramic, so of desulfurization
is put forward.
