Iron, Steel and Ferro-Alloy

Our Applications

Hydrochloric acid (HCl) is a strong inorganic acid which is widely used in the chemical and other industries, e.g. for chlorination processes, production of vinyl chloride (plastics), TDI/MDI (polyurethanes), pickling of steel, pH control, neutralization, and regeneration of ion exchangers.

Our corrosion resistant systems and equipment solutions enable safe and efficient synthesis and processing of HCl gas and HCl acid. We have built more than 500 HCl synthesis units, among those the biggest synthesis units worldwide. Our innovative steam generation, two pressure distillation and extractive distillation systems are designed to maximize energy efficiency of HCl processing.

Hydrofluoric acid (HF) is the core component for fluorination reactions. It is the precursor for numerous pharmaceuticals and diverse materials such as polytetrafluoroethylene (PTFE). HF also plays a key role in the procuction of aluminium and uranium.

We offer a comprehensive range of corrosion resistant systems and equipment solutions for the processing of hydrofluoric acid. Examples are systems for the cracking of HCFCs to HF as well as SiC heat exchanger for steel pickling and chemical etching of glass.

Sulfuric acid (H2SO4) is a strong inorganic acid which is widely used in the chemical and other industries. Principal uses include lead-acid batteries, ore processing, fertilizer manufacturing, oil refining, waste water processing and chemical synthesis.

We offer a comprehensive range of corrosion resistant system and equipment solutions for the processing of sulfuric acid. Examples are systems for the dilution of concentrated acid and equipment for the reconcentration of diluted acid.
