Coke Wastewater Treatment. This process provides both heat and carbon (coke) required for iron production. During this process the volatile materials contained in the coal are driven off, leaving coke as the product. Gas produced by coking is withdrawn by means of blowers to recover energy-rich byproducts, including methane.

Jan 10, 2019 · A similar FTIR spectrum was obtained in a previous study on the recycling process of a rolling mill sludge based on a distillation step followed by either an oxidation or a reduction treatment (Liu et al., 2013a). This suggests that the sludge is representative of those from other steel works.
In principle the treatment of storage tank bottom sludge and water is similar to that of slop oil dredged from lagoons. Although a 3-phase decanter only can be applied here with good results, the high solids content of the product means that a combination of 2-phase decanter plus 3-phase separator.
