Iron slag permeable reactive barrier for PFOA removal by …
— The affinity of iron slag to PFOA enhances its removal during the EK process. Increasing the iron slag to AC ratio from 50%− 50% in experiment E2 to 70%− 30% in experiment E3 slightly increased the PFOA removal from 75% to 79.25%. Comparing experiments E3 and E5 shows that PFOA removal was improved when NaC …
Optimal hot metal desulphurisation slag considering iron loss …
— The optimal hot metal desulphurisation (HMD) slag is defined as a slag with a sufficient sulphur removal capacity and a low apparent viscosity (ηslag) which leads to low iron losses.
Full article: Lowering iron losses during slag …
— ABSTRACT. To lower the iron losses of the hot metal desulphurisation (HMD) process, slag modifiers can be added to the slag. Slag modifiers decrease the apparent viscosity of the HMD slag. Most …
