hi all,
this question concerns the hydrogen plant deaerator.
whenever we take the process condensate in the deaerator of our unit the conductivity goes very high i.e. 5-6.with only dmin water coming to the deaerator it is about 2.
and though all other parameters are within limits this we have not been able to control.we increased the blow down rate to its' maximum but did'nt help.
and one more thing ,we have hydrazine and morpholine dosing for oxygen scavenging and ph control in our deaerator.
what is the preferred location for the dosing of these chemicals?
currently we are dosing morpholine in the deaerator vessel and hydrazine in the bfw pump suction i.e. vessel outlet.
