The venturi throat from SMS group helps to reduce emissions significantly.
As part of a planned increase in the production capacity of the three 190-ton converters, the gas cleaning plants, installed in the 1970s, were upgraded to the state of the art and now provide far more efficient cleaning results. Offgas emissions were reduced to below 25 mg/Nm³; the legal limit is 50 mg/Nm³.
Cesar Alejandro Parisi, Ternium Argentina, Head of Plant Development Department for Hot Rolling Mill and Steelplant:
“This upgrade of our gas cleaning plants means we are ideally equipped to meet the environmental challenges of the future. The performance of SMS group’s environmental technology comes up to and even exceeds our expectations.”
For the revamp of the three scrubbers, SMS group supplied key components as well as two main induced-draft fans for gas cleaning. The venturi throat, developed by SMS group, features a new type of nozzle geometry and arrangement, which ensures extraction of a larger quantity of dust particles.
The scope of supply also included the measuring technology for the venturi scrubber and the whole gas cleaning plant, including the cooling stack, as well as the supervision of the erection work and commissioning.
