..., the cleaning fluid step was under static conditions at 250-300°F and 250 psi. Fig. 3 Dynamic HP/HT filter press HCl acid cannot be used to dissolve Mn 3 O 4 -based filter cake at high acid concentrations because of chlorine gas release. At low HCl concentrations, Mn 3 O 4 -based filter cake...
