METHOD OF DETERMINATION OF SPECIFIC CONSUMPTION OF ANODE MASS Russian patent published in 2006 - IPC C25C3/12 

FIELD: electrolytic production of aluminum; method of determination of specific consumption of anode mass in self-roasting anode and determination of specific consumption of anode mass by equation.

SUBSTANCE: method includes additional determination of anode mass destructability in current C0₂ and magnitude of anode mass specific consumption is determined from the following equation: P_am=K_el.f.+333/bη+1.2(T_el.t.-960)/b+1.6P_CO2/b, where P_am is specific consumption of anode mass, kg/t of aluminum; K_el.f. is electrolizer coefficient characterizing additional consumption of anode mass determined by average static annual data for each plant; η is current efficiency, fractions of unit; T_el.t. is electrolyte temperature, °C; P_CO2 is index of anode mass destructability in CO₂, mg/cm²/h; b is carbon extraction from anode mass to self-roasting anode, fractions of unit.

EFFECT: possibility of predicting efficiency of anode use; low cost of aluminum.
