Filling of concentrated nitric acid to rail tanks

BorsodChem MCHZ, s.r.o. – filling of concentrated (99%) nitric acid to rail tanks. 

KROHNE magnetic-inductive flowmeter ALTOFLUX IFM 4020 F/D DN 50 with tantalum electrodes is used for precise dosing of this corrosive liquid. The dosing device was projected and constructed by BorsodChem MCHZ technicians in a very short time.



The BorsodChem MCHZ, Ltd. (Ostrava, Czech Republic), a member of the BorsodChem Group, is the worlds´ greatest producer of cyclohexylamine and an important European producer of amines, particularly aniline.

Top products include also nitric acid, oxalic acid, formaldehyde, nitrobenzene, urea-formaldehyde resins (commercial name „Dukol“) and technical gases.

First KROHNE variable area flowmeters were installed in this plant more than 20 years ago and some of them have still been in use. At present the BorsodChem MCHZ company is one of KROHNE CZ key customers. Several dozens of various KROHNE instruments are used here to monitor and control production processes.

All-metal variable area flowmeters measure the flowrate of amines, condensate, benzene, aniline, nitrogene, hydrogene, etc. Proven KROHNE magnetic-inductive flowmeters ALTOFLUX IFM 4080 are installed here to measure various corrosive liquids, such as nitric and sulphuric acids. Most important KROHNE CZ orders in BorsodChem MCHZ include level measurement in the combustibles storage (16 pcs of KROHNE level radar BM 70 and BM 700), in the aniline production line (9 pcs of BM 70A) and in the caustic agents storage (10 pcs of KROHNE 2 wire level radar BM 702).

The customer also purchased KROHNE TDR level meters BM 102 (measurement of amines) and BM 100A (measurement of granulated urea). Proven and reliable KROHNE level indicators BM 26 are used to measure level of condensate and demineralized water.
