Case study - Dosing of Sulfuric acid into potassium salt
A Swedish chemical producer needed to add sulfuric acid to potassium salt, as a step in their production of hydrochloric acid. The challenge was that the dosing needed to be very accurate over a long period of time.
Technical solution
Ramén found the solution in a research control valve from Badger Meter which has a long and proven record of successful service in this type of application. The Badger Meter RCV ½” (Model RC 230) control valve had an electric actuator and trim in Hastelloy C. It is a seat valve which gives the highest accuracy and Kvs-value adapted for continuous dosing of small quantities.
The electric actuator makes it possible to precisely set the valve opening and thereby get a very accurate dosing. The trim in Hastelloy C has good resistance to the hydrochloric acid.
