Coatings and acid-resistant brick linings – how to ensure long-term economic benefits

Our services for this project include project management, surface preparation, corrosion protection systems application and continuous quality control.

Do to the exposure of tanks to a wide variety of aggressive acids (phosphoric and sulphuric) and mechanical stress, essential anti-corrosion measures were selected for each tank according to the particular chemical, mechanical and specific environmental conditions.

Our services in this project were divided into 3 factories:

1. Sulphuric acid plant

2. Phosphoric acid plant

3. Leach plant

• Sulphuric acid plant

Surface: 1,625 sqm divided into 9 carbon or stainless steel tanks

Technical solution and services: 3 layers of acid-proof brick lining and rubber membranes (2mm thick rubber membrane). Approx. 30% of acid-proof brick lining was applied in a triple layer and the remaining 70% in a double layer. The acid proof bricks embedded and joined with acid proof mortar had different sizes and thickness (40 mm – 115 mm)

• Phosphoric acid plant

Surface: 14.557 sqm divided in 14 carbon steel tanks, concrete flooring, channels and concrete reaction vessels.

Technical solution and services: inside anticorrosion protection work. The applied systems were composed of:

•       rubber membranes (4mm and 5mm thick) (14.557 sqm)

•       acid-proof carbon bricks and tiles (with a thickness of 20mm – 120mm), joined with acid proof mortar (12.000 sqm)

•       multiple layers of linings (resin layers, reinforced fiberglass layers, epoxy coatings), highly resistant to acids (28.000 sqm)

• Leach plant

Technical solution: We applied acid proof tiles (25 mm thickness) with corresponding acid proof mortars in channels and sumps (1.690 sqm), and we performed epoxy and polyurethane-based lining application (thickness from 2 to 5 mm) on concrete floors and concrete columns (15.013 sqm).

Also in this plant, we applied acidproof rubber membranes in 14 carbon steel tanks (3.900 sqm).
