Implementation of a parallel flow device in a pickling tank

In September 2018, a new and innovative approach to the use of the parallel flow device (PFD) was implemented at voestalpine BÖHLER Bleche GmbH & Co KG in Mürzzuschlag, Austria. Altogether, the installation comprises of three elements for improving the performance in the pickling tank and saving hydrofluoric acid.

For a better movement and thus optimised kinetics of the pickling process, the acid circulates through a series of nozzles via a parallel flow device at the top end of the tank. This provides a perfectly guided flow to ensure a more homogeneous acid distribution.
In order to prevent the overheating of the acid, the steam injection is circumvented by the implementation of an instantaneous heating unit. This ensures a constant but adjustable temperature in the entire tank. 
As another benefit resulting from the circulation of the acid, a filtering unit is installed at the intake socket of the pump. This filtering unit can be removed and the suspended solids collected in the filter can be removed periodically.

The given drawing shows the assembly of the unit.

With the overall aim to save time for pickling, safe hydrofluoric acid by temperature control and filtering unit and safe costs by stop using the steam generator, we are convinced to set new standards in pickling units together with voestalpine BÖHLER Bleche GmbH & Co KG.

Poly TBRC - Latest generation of copper refining and smelting process

For our customers in Germany and Russia the PolyTBRC is in latest stage of construction

The installation of this special TBRC converter, as a joint project of PolyMet Solutions, SMS group, Urban Gold and Mettop, will allow our customer to increase the recycling capacity of copper scrap whilst, at the same time, improving process quality, efficiency, and safety.

The benefits for our customers when installing of a PolyTBRC can be highlighted:

Improved heat transfer and reaction kinetics in refining and smelting processes.
The oxygen/gas-combustion system produces an intense, stable and compact flame with very efficient heat transfer capabilities and low exhaust volume flow.
Lambda values can be adjusted over a wide range to produce reducing, neutral or oxidizing conditions.
High ration of metals recovery and flexible process performance with good slag-metal separation.
ILTEC cooled lance for injection purposes.

We are looking forward to hearing from you if there are any questions or you need more information regarding our PolyTBRC.

ILTEC System ready for Installation

ILTEC facility for Spanish customer is finally ready for shipping

The newly constructed ILTEC facility is equipped with four individual cooling lines which enables the cooling of large areas and applications. Furthermore the cooling capacity of the two heat exchangers of 1.500 kW each and the pumping capacity of 50 m³/h guarantee the appropriate removal of larger heat amounts.  

Gas purging for improving performace 

In order to improve the efficiency of different types of furnaces in metallurgy, Mettop offers various gas purification systems. The system consists of a set of rinsing elements, such as porous plugs, the corresponding closing system for the furnace steelworks, and a gas regulating unit.
