Apeks Transformer Supercritical CO2 Extractor + Ancillary

Apeks Transformer Supercritical CO2 Extractor, PDC3 compressor and Polyscience chiller, all with low hours.

System Specifications

Extraction Vessel

• Volume – 40L vessel holds around 20 pounds of dry, ground material
• Pressure – maximum pressure = 2000 psi (137 bar)
• Temperature – max 160°F (71°C)
• Materials – 304 stainless steel. Vessel interior is polished to food grade level.
• Closures – Hammer Union (commonly used in oil and gas industry for temporary piping), top with integral hinge
• Sealing mechanism – spring energized cup seal
• Filter – integral filters on closure heads. 20 micron.
• Temperature measurement – internal K type thermocouple senses actual extraction temperature
• Safety – non-isolable spring loaded safety relief valve prevents accidental over-pressurization

CO2 Recirculation Pump

• Electric motor driven diaphragm compressor
• Flowrate – 1.0-2.1 kg/min
• Construction – hydraulically actuated diaphragm
• Materials – all wetted parts are 316 stainless steel
• Safety – non-isolable spring loaded safety relief valve prevents accidental over-pressurization

Separators

• 1 separator bank on each unit
• Pressure – Maximum pressure = 600 psi (41 bar)
• Temperature – max160°F (71°C)
• Materials – 304 stainless steel
• Closures – FDA sanitary style bolted
• Sealing mechanism – sanitary gasket, cured silicone
• Safety – non-isolable spring loaded safety relief valve prevents accidental over-pressurization

Separation Mechanism

• Valveless Expansion Technology (VET) – flow path from extractor to 1st separator is continuous diameter with no constrictions. Separation occurs in 1st separator utilizing centrifugal separation and depressurization.

Heat Exchangers

• Construction – tube in tube style
• Materials – 304 stainless steel
• Cooling/Heating media – water

Chiller/Heater

• Recirculating chiller/heater
• Temperature range: -10°C to 50°C (14°F to 158°F)
• System operational range: 60°F-140°F
