Supercritical Fluid Extraction Machine-SFE CO2 Extractor Review

Supercritical CO2 Extraction Machine Crucial Parts
A full set of cox extraction extractor that designed for industrial use purposes mainly contains components such as co2 extractor, separation tank, fine distillation column, co2 high-pressure pump, entrainer pump, refrigerating system, heat exchange system, purifying system, pressure stabilizing system of extraction kettle, co2 storage tank, flow meter, temperature, and pressure control (protection) system, etc.

1. Extraction Kettle
where crushed dry or wet raw material put; the extractor works under high pressure about 40-50Mpa; the extraction tank can be manufactured from small lab size to industrial big volume, ranging from 0.5L, 1Liter to 200L per extraction kettle. 2L. 5L/50Mpa. For lab size co2 extractor, the kettle can be taken out and loaded manually. But for big size where the extractor is so heavy, we will make traveling crane and lifting clamp on top of each kettle. The kettle can be lifted up by the above crane.

2. Separation Kettle/Separator
to match the extractor usage need, the separation tank has sizes from 0.3liter to 100L. The effective ingredients come down from the bottom of separators.

З.Fіnе Dіѕtіllаtіоn Соlumn(not shown in above FIG.)
certain raw material needs to be distilled and purified under the impact of distillation. So the whole co2 extraction system can either have this distillation column or not depends on the raw material property. But if the buyer has many types of materials to be extracted, we suggest them to have a full complete set of co2 oil extractor multiple functions. The distillation column can be designed with 4 sections, 6section or more. So the user can use the co2 oil extractors in three ways:
A. Use extractor and separator only.
B. Use extractor, separator, and distillation by the workflow steps.
C. Jump directly to distillation, the material does not go via extraction or separation.

4. High-Pressure co2 Pump
where liquid co2 runs through and pumped out to extractor with very high pressure. Bigger overall co2 extractor requires a bigger power pressure pump. Normally, we design like this 20L with 40Mpa; 50L/50Mpa, 400L/40Mpa, and 800L/40Mpa of single, double or triple-plunger frequency-regulating. A cooling system is installed at the pump core to protect over-heating or dry burning.

5. Co-Solvent Pump
during the co2 extraction process, certain material reaches the best efficiency under the help of co-solvent besides co2. In this way, the co2 extraction system usually comes with an extra co-solvent pump. The co-solvent works as a catalyzer to maximize the limitation for a wider application.

6. Cooling System
equipped with a semi-closed loop a full closed-loop compressor to meet the cooling capacity technological requirement. A set of industrial water chiller and water storage tank will be installed to make the co2 extraction process go on successfully.

7. Heat Exchange and Temperature Control System
according to PID, the extractor, separator, and distilling column are equipped with heating and cooling systems and independent temperature control systems. For water circulation temperature range: room temp. to 85℃;  The oil circulation temperature range: room temp. to 150℃; For CO2 fluid accuracy is ±1℃ using digital display temperature gauges.

8. Carbon Dioxide Recycle Pump
even though our closed-loop CO2 extractor has a build-in co2 circulation system where users can save energy consumption; still, a certain percentage of co2 will be wasted. So an extra CO2 recovery pump can be chosen to installed into the extraction machine too to increase the utilization of solvent.

8. Pressure Control (Protection)
an electro connecting pressure gauge is installed at the outlet of the high-pressure pump and set the working pressure to release pressure and make automatic protection in case overpressure occurs; Safety valves are allocated with equipped with high-pressure co2 pump, co2 extraction kettle, separation kettle, and distillation column according to their maximum working pressures to release pressure and make automatic protection in case overpressure occurs; back-pressure valve system at the outlet of the extraction kettle has a counterbalance pressure valve with accuracy ±0.1Mpa.

9.Pipelines
all containers, valves, pipe fittings and pipelines contacting with fluid are all made of stainless steel.

Below are some constantly asked questions concerning buyers for the supercritical fluid extraction system. 

1. Can CO2 extractor also use other solvents like alcohol?
Sometimes, yes. Alcohol or not depends on the material (can’t be absolute; e.g. HEMP extraction, no need alcohol); some material needs alcohol to speed up extraction or to get a more valuable result.

2. What is final product from CO2 machine only oil or other ingredient too?
For highly oily material, like seeds; come out as oil; for hemp, come out as mixture. The user needs to test the ingredients from extracts.

3. How much is CO2 consumption?
This also depends on the material, but for example for a set of c02 extractor size 24L*2(equal to 50L extractor), the first time charge, 90kg CO2 is needed; if run as continuously, maybe 7-8bottles are needed for 24hours production, each bottle around 20kg.

4. How much CO2 can be recycling?
The cox extractor system itself is with a built-in co2 recovery system that can recycle 60% of carbon dioxide; the user can also buy an extra co2 recycling pump to increase the recovery rate to 80-90%.

5. How much is the production cost per extraction batch?  of the cost to finish one 50 litter batch?
Well, we have many models of supercritical extraction machine/SFE system; we’d like to give a general data based on a 50L extractor. Power consumption: 50kw*3hour; CO2 consumption: 30kg/ circle

6. How much of the maintenance cost per year?
If you have a good operator, there will be little maintenance; sealing rings depends on the machine use frequency.

7. If a user wants to test, how much material should we bring?
The minimum raw material needed for our test is 2kg;

There are several ways to get cannabis oil such as ethanol extraction under low temperature; BHO extraction using butane as a solvent; and supercritical fluid extraction using co2 as the solvent.

Supercritical Fluid CO2 Extractor Glossary of Terms and Technical Parameter

To help users and buyers a better understanding of what is SFE(supercritical fluid extraction), below is a list of terminology that can be referred to briefly. (if any mistake, please contact us for correction)

Supercritical Fluid
A supercritical fluid ( shorten as SCF) refers to a substance at a certain temperature and pressure that is above its critical point. We can clearly tell whether it is in the gas phase or liquid phase because there is no distinct difference. SCF can permeate solids like a gas, and dissolve materials like a liquid. Besides, when it is near the critical point, changing pressure and temperature even at very small changes will affect greatly the density of the supercritical fluid. Thus the SCF can be “fine-tuned”;

Supercritical Fluid Extraction
Supercritical fluid extraction (abbreviated as SFE) is the process to separate one component (whether unwanted or ideal) from another (the matrix) using the supercritical fluid as the extracting solvent. Extraction can either from a solid matrix or from liquids, the former is most commonly seen.

Supercritical CO2 Extraction
In the process of Supercritical fluid extraction where we use Carbon dioxide (CO2) as SCF is called Supercritical co2 extraction. CO2 is the most used extract solvent due to its versatile property and advantageous performance.
Closed-loop extraction(Round loop extraction):

Co2 Extractor
also known as supercritical co2 extraction machine, is a machine manufactured to fit the SFE extraction process. It is a simpler name instead of the full name.

Co-solvent
Sometimes during co2 extraction, there is a need to modify the solvent property to make the best use of its extremity by using co-solvent such as ethanol or methanol. It works similarly to a catalyzer.
