Physical chemical treatement - oil refinery

For a project in the Czech Republic in a refinery, Novotec supplied a flotation unit, polymer unit and Squeez-R unit. For the specific application in the oil industry, Novotec designed a completely closed flotation that uses nitrogen gas instead of compressed air to make saturated water. The unit processes 5 m³ / h waste water. An automatic stainless steel polyunit was supplied for the flocculant dosage. But the most challenging part was the accompanying Squeez-R unit, which dehydrates the flotation sludge. This unit was delivered in ATEX version according to marking II 2G Ex h IIB T3 Gb
