For the leading ethanol production plant, we have delivered 5 underground, double-skinned tanks, each with a capacity of 200 m3, diameter 3400 mm and length of 23 m. The tanks were equipped with control and measuring system compliant with the ATEX directive and fulfilling Customs office requirements (for tax and excise duty). These are the first double-skinned tanks of such a capacity produced by CGH Polska.
One of those tanks – made in a four-chamber version – was designed to store ethanol-based additives. The other four single-chamber tanks were adapted to be equipped with vertical agitators. As ethanol fumes are highly flammable, design and equipment comply with EX standards.
The tanks are an important element of the technological line and are designed to thoroughly mix contaminated ethanol with additives.
