where:
%PHg = percent reduction of the potential mercury emissions achieved.
Ei = potential mercury emission concentration measured at the control device inlet, corrected to 7 percent oxygen (dry basis).
Eo = controlled mercury emission concentration measured at the mercury control device outlet, corrected to 7 percent oxygen (dry basis).
where:
%PHCl = percent reduction of the potential hydrogen chloride emissions achieved.
Ei = potential hydrogen chloride emission concentration measured at the control device inlet, corrected to 7 percent oxygen (dry basis).
Eo = controlled hydrogen chloride emission concentration measured at the control device outlet, corrected to 7 percent oxygen (dry basis).
