Case Study – Check Valves

Case Study – Check Valves

When designing a high pressure pump the check valve design is usually overlooked and commercially available ones are used.  However, the check valve design can dictate the motor size. The greater the back flow, the more the motor needs to compensate for the loss in...

Case Study – Basket Design

When performing an extraction, the most convenient accessory is the use of an internal basket.  The basket allows you to both load and unload your extraction vessel relatively quickly giving you two major benefits. Quick loading and unloading allows increased...
Importance of CO2 Feed from Density to Flow (Part 3 – Flow Meter)

Importance of CO2 Feed from Density to Flow (Part 3 – Flow Meter)

We have discussed how flow meters can aid in troubleshooting the incoming CO2 flow.  They are however, much more powerful than this.  One of the most important metrics in any extraction is the solvent to extract ratio.  This is the grams or kilograms of CO2 per gram...
