the research aimed to apply the taguchi method for techno-economical evaluation of cr+6 removal using the electro-coagulation process with the aid of two different coagulants (fecl3 and pac). taguchi orthogonal array l27 (313) was applied for analyzing the effect of four variables including initial ph, reaction time, current density and coagulant types in an attempt to improve the chromium remo...

The technical equipment developed and used in both installation and operation processes in refineries, oil and gas pipelines, and gas booster stations has always been expensive. Hence, managers at different organizational levels are keen to find methods to control and reduce these costs. Generally speaking, the operators in a gas booster station choose the operating devices without considering ...
