HERE'S HOW PETROTEQ'S EXTRACTION TECHNOLOGY WORKS

Stage 1: Crushed ore delivered into patented fluidized bed extractor. Extraction process is performed at temperatures between 50-60 C degrees
Stage 2: Solvent composition with extracted oil bitumen is delivered from extraction column to the evaporator and then to distillation column.
Stage 3: Hydrocarbons (oil/bitumen) are extracted from the solvent in the distillation column and pumped to the storage tank.
Stage 4: Solvent is recycled, warmed up and returned back to the extractor within the continuous flow, closed-loop system.
Stage 5: Purified sands leave extractor and go through the drying process.
