Denitration Column Delivery
In the month of October 2016 we handed over, to a full customer from Lovochemie, Lovosice, Czech Rep satisfaction, a denitration column within the implementation of the project "New denitration column for Nitric Acid Production Line KD5".
The denitration column is proposed to remove dissolved NOx and to oxide of nitrous acid HNO2 by means of counter-current secondary air. This process is also called as “bleaching of production acid”.
There were the column proposal, manufacturing and delivery, installation in a place of original column and connecting to pipeline systems in our delivery scope. We provided guarantee to stripping column efficiency (the content of nitrous acid in bleached acid) to the customer. There was nitrous acid content 0.0075 mg / l determined within guarantee measurement. Our customer acknowledged that the effectiveness of the new column is about 5 times higher compared with the original column efficiency.
