In domestic extraction plants, it is common to use several 100-500 liter extractors. Examples from around the world have produced large pressure vessels (up to 6500 liters), as shown on the right figure. The plant for processing wine cork stoppers (Q.7) that went into operation in France has three 19,000-liter extractors with a pressure of 13 MPa (2015). However, there are various restrictions to install such a large scale pressure vessel, such as transportation, applicable laws and regulations in the country of installation (especially the High Pressure Gas Safety Act in Japan is very strict), and so on.
The pressure vessel capacity and flow rate determine the time required for pressurize. It has extremely high variability, as shown in the figure on the right.
