How It Works
Bulk Tank or Microbullk Unit:
CO2 is stored in this unit in a Liquid Phase . Weldcoa does not manufacturer bulk tanks or microbulks however we do have a long history of working with tanks and have close relationships with bulk tank suppliers in the gas industry. The components that are needed for this unit, in order to be compatible with our modular skid, are liquid withdrawal and gas/liquid return ports. The tank size will be determined by the extractor size and the number of cycles to be run per day.
Weldcoa CO2 Modular Pump/Vaporizer Skid Unit
This system is best suited for Extraction Equipment of 40 Liters or Larger. The Skid Unit consists of a CO2 pump, automation controls, vaporizer, piping and valve assemblies, all on a steel skid base. This modular unit is provided, tested, and remotely supported by Weldcoa.
1. CO2 product, in a Liquid Phase, is piped from the bulk tank into the Pump (which is on the skid unit) and then piped out of the Pump, in a Liquid Phase, into the Vaporizer (which is also on the skid unit).
2. Once in the Vaporizer, the CO2 product is converted into a Gas Phase and is then piped to the Buffer Vessel Station(s) still in a Gas Phase.
3. This process is managed and controlled by Weldcoa’s automation.
4. From the Buffer Vessel Stations, the CO2 product, still in a Gas Phase, is piped into the Extractor inlet
Weldcoa Buffer Vessel Stations
The number of Buffer Vessel Stations needed depends on your volume and quantity of your extraction equipment. This process is managed and controlled by Weldcoa’s automation, holding the CO2 product in Gas Phase at 750 to 900 PSIG.
• One station is capable of supplying gas to extractor equipment with capacity of 1 to 100 Liters
• Two stations are capable of supplying gas to extractor equipment of 100 to 200 Liters
• Three stations are capable of supplying gas to extractor equipment of 200 to 300 Liters
• Four stations are capable of supplying gas to extractor equipment of 300 to 400 Liters
As the client’s extraction volume increases, they can easily accommodate the demand by adding another Buffer Vessel Station to increase their storage capacity.
How It Works
Extraction Machine:
Typically, an Extractor consists of a Solvent Chamber(s) ranging from 2 to 400 Liters, an Expansion Chamber(s), an oil collection vessel, a CO2 gas recovery system and automated controls with an operator touchscreen terminal. None of this is provided by Weldcoa.
5. From the inlet, the CO2 product, in Gas Phase is piped into the main Solvent Chambers of the Extraction Machine where the temperature and pressure of the CO2 product is then adjusted, converting the CO2 product from a Gas Phase into a Supercritical Phase. The time it takes to fill up the Solvent Chamber and regulate it to these specific parameters is called the “Charging Time”.
6. Once the correct temperature and pressure are achieved, the system pumps the supercritical CO2 in a loop for a specific amount of time. This is called the “Looping Cycle”. As the material passes through the Expansion Chamber the Supercritical CO2 coverts back into a Gas Phase, allowing the oil to decondense and drop into the oil collection vessel, providing a final product/ yield from the extraction process. When the entire cycle is complete, the CO2 gas is vented into a recovery system for reuse in the next charging cycle.

As the client’s extraction volume increases, they can easily accommodate the demand by adding another Buffer Vessel Station to increase their storage capacity.
The number of Buffer Vessel Stations needed depends on your volume and quantity of your extraction equipment. This process is managed and controlled by Weldcoa’s automation, holding the CO2 product in Gas Phase at 750 to 900 PSIG.
√ One station is capable of supplying gas to extractor equipment with capacity of 1 to 100 Liters
√ Two stations are capable of supplying gas to extractor equipment of 100 to 200 Liters
√ Three stations are capable of supplying gas to extractor equipment of 200 to 300 Liters
√ Four stations are capable of supplying gas to extractor equipment of 300 to 400 Liters
HOW TO DETERMINE WHAT CO2 SUPPLY SYSTEM YOU NEED
There are a number of factors that affect how to optimally size a system; such as how much recovered CO2 will be reused, pump may be running during the charging cycle, etc. But the below listed steps will be a good starting point of reference.
Step 1
The first thing we need to do is to determine how much CO2 storage we need to charge your extractors as quickly as possible. This allows us to start a new cycle with less down time in between. Less down time will increase the number of cycles we can run in a given time period. Weldcoa offers Buffer Vessel Stations To determine how many you will need, please see below.
1. Add together the chamber capacities of all of your extractors. (Example: you have 1 – 100 Liter and 2-40 Liter units for a total of 180 Liters)
2. Divide total chamber capacity by 100 (Example: 180 Liters divided by 100 equals 1.8 rounded to 2)
Based on the above example we have determined we will need 2 CO2 Buffer Vessel Stations
Step 2
You need to determine what pressure range your extractor requires to operate efficiently. You will need to contact the extractor supplier for this information. (Note: 600 PSI Min. to 900 PSI Max. is very common.)
Step 3
You need to decide what size pump skid is needed. The size of the pump skid is determined by how fast we want to refill the CO2 Buffer Vessel Stations before we can charge an extractor for the next cycle.
If you only have one extractor and a cycle is 60 minutes we do not need a large pump skid. If you have several extractors and will be charging one after the other, a larger pump skid will be required to minimize the refill time.
To pick the correct pump skid please refer to the table “Usage and Recovery Time” to the right.
Additional things to consider:
If you think your business is going to grow you should select a larger pump skid as the flow rates on these cannot be changed economically. As for the CO2 Buffer Vessel Stations, these can be added at any time to accommodate new equipment, faster charge times etc.

Example:
You have one 200 liter extractor and from step one you have determined you need Qty-2 CO2 Buffer Vessel Stations. You have talked to you supplier and determined the pressure range you need is 600-900PSI. You have an approx. cycle time of 60 minutes. Go to the table and find the 600-900 PSI in the first column which will be the blue rows. Next go the second blue row which is the 2-CO2 Buffer Vessel Stations we determined we needed. Going across you can see four different recharge times. Since we have 60 minutes between charging cycles, we could select the smallest pump skid 1.25GPM/30KW.)
