Supercritical CO2 Processes

SciMed is the leading provider of components and turnkey systems for supercritical and other high-pressure CO2 applications. SciMed provides solutions from the smallest scale (10ml) up to the production scale (250-500 litres), making usa unique provider within the EU.

SciMed exclusively represents the worlds leading Supercritical CO2 company, Core Separations (connected with Thar Technologies which was taken over by Waters).
Core Separations specialises in laboratory scale systems from 1ml to full scale production solutions. It also provides specialised laboratory scale solutions as well as toll processing and proof of concept work.

SciMed can provide the following components which are purpose built for SC CO2 applications:
– High-pressure pumps for both CO2 and co-solvents
– Manual and automated back pressure regulators
– Pressure vessels from 1ml to 500L (with or without windows)
– High-pressure view cells
– High-pressure reactors.

Lab Scale Systems

SciMed has over 20 years direct experience of Supercritical CO2 processes. Together with our partners Core Separations, SciMed can offer a complete range of systems, often tailored to suit very specific and one-off design requirements, as well as standard “off the shelf” solutions. All the systems provided by SciMed are modular and can therefore be modified with ease, as and when requirements change. SciMed has supplied numerous systems for all Supercritical CO2 applications including: Reactions in Supercritical CO2 SFE: Supercritical Extraction solutions for solids as well as counter column systems for continuous extraction of liquids Particle generation using CO2 as…

Pilot and Production Scale Systems

For all systems above 10 litres in vessel volume, the products are classified as pilot scale or production scale. SciMed can provide bespoke solutions for such larger scale requirements. Our dedicated team can discuss your requirements factoring scale, throughput, space restrictions, ATEX, automation and many other aspects relevant to such larger scale projects. Scimed – An SFE Journey 2000-2020 Over the last 20 years Scimed has been providing SFE technology into a number of different industries. We have worked with some of the pioneering providers to offer customised solutions from including Waters and Separex which was created by Michel Perrut…

P251K 1000 bar CO2 Pump

Supercritical CO2 Pumps

Supercritical fluids are very dense fluids, with superior properties when compared to liquids or solvents. The most commonly used of these fluids is CO2. Unlike solvents, it has a much less harsh impact on the environment. Pumping high density liquid CO2 requires supercritical CO2 pumps, such as the range of high-pressure pumps from Core Separations. Why is Supercritical CO2 So Effective? Once it reaches critical temperature, CO2 remains a gas-like fluid, combining the solvating power of a liquid with the diffusion properties of a gas. Adding small amounts of fluids or other modifiers can improve its solvating properties. Applications for…

High Pressure CO2 Recycler

A recycling system can be used to recycle carbon dioxide after collection system (high pressure fraction collection vessel). This system consists of storage vessel with level sensor for carbon dioxide storage, level sensor module to display level, condensing heat exchanger, condensing cooling bath, and valves. The system also features pressure relief valve that can be piped to vent to relieve pressure in case of over-pressurization or overfill conditions. Fill conditions in a system are dictated by operating conditions. Based on display of level sensor module, user switches carbon dioxide supply to system from carbon dioxide source or to storage vessel…

Supercritical ABPR

High Pressure Automated Back Pressure Regulator

The back-pressure regulator consists of a pneumatic–driven valve assembly controlled by a Core Separations adaptive pressure control system, (APC™). The high–strength stainless steel needle and reinforced PEEK seat have a high resistance to erosion and allow stable pressure control over a wide pressure range. Using a pressure sensor the SFX software provides adaptive closed loop feedback in-order to provide extremely accurate pressure control. CO2 flow rate 0.5 g/min to 350 g/min Closed-loop control SciMed – An SFE Journey 2000-2020 Over the last 20 years Scimed has been providing SFE technology into a number of different industries. We have worked with…
