Recycling – CO2 Condenser The condenser is essential in CO2 recirculation. The condenser is a piece of apparatus or equipment that can be used to condense, that is, to change the physical state of a substance from its gaseous to its liquid state. We use double pipe configuration in small systems … [Read more...] about Recycling – CO2 Condenser
Coriolis flow meter
Coriolis flow meter The Corilolis flow meter is basically a mass flow meter. It gives you exactly the mass of CO2 is delivered by the membrane pump, with at least three advantages if compared to traditional meters:It has no moving parts. It works at full pressure at the outlet of the pump … [Read more...] about Coriolis flow meter
CO2 Level – Find the equilibrium points
CO2 Level – Find the equilibrium points We say that a liquid is in equilibrium with its gas when the same mass is exchanged from the gas to liquid and from liquid to gas. This happens continuously, and this point id strongly dependent on pressure and temperature. The change in temperature … [Read more...] about CO2 Level – Find the equilibrium points
Gravimetric Separator
Gravimetric Separator This is the first Separator (S1). It applies the gravimetric effect to separate the extract in fractions. This separator is heated at set-point temperature. When the mixture of CO2 and chemical compounds extracted are directed in this separation, the solvent’s temperature … [Read more...] about Gravimetric Separator
What is a Cyclonic Separator?
What is a Cyclonic Separator? This kind of separator is different compared to the gravimetric separator, while S1 works by gravity force, S2 works by centrifugal force. The fluid moves very quickly creating a vortex inside the vessel. The fluid continues to spin and the particles of extract … [Read more...] about What is a Cyclonic Separator?
What is a Membrane Pump?
What is a Membrane Pump? Separeco doesn’t use piston pumps or compressors in its systems, but diaphragm metering pumps only.Although the cost is higher if this kind of pump is compared to a simple gas booster or piston pump, the advanteges are really considerabile.In fact, diaphragm metering … [Read more...] about What is a Membrane Pump?
Extraction efficiency of CO2
Extraction efficiency of CO2 Supercritical carbon dioxide isn’t only a efficient solvent for apolar compounds, in fact, if it’s combined with fluid modifiers like water, it becomes a very efficient solvent also for medium polar and polar substances (caffeine for coffee decaffeination).The … [Read more...] about Extraction efficiency of CO2
ESE Enhanced Solvent Extraction
ESE Enhanced Solvent Extraction Supercritical Carbon dioxide is a great solvent for apolar substances. Our compressed water and carbon dioxide extraction system allows the extraction of polar substances. The action of carbon dioxide is to Permeate Matrices, coadiuvating water’s solvent action. … [Read more...] about ESE Enhanced Solvent Extraction
Separation and fractionation processes
Separation and fractionation processes After the extraction process, the mixture composed by CO2 and solutes leaves the extraction vessel(s) and it is directed to the separation vessels. By varying the pressure, flow and temperature of these vessels, it is possible to induce the selective … [Read more...] about Separation and fractionation processes
Supercritical CO2 Solubility
Supercritical CO2 Solubility Supercritical CO2 extraction process depends by CO2 solubility. Particularly is “geometrically variable”. A supercritical fluid is any compound at a temperature and pressure above its Critical Point.It can diffuse through solids like a gas, and it can dissolve … [Read more...] about Supercritical CO2 Solubility
ASME – American Society of Mechanical Engineers
ASME – American Society of Mechanical Engineers We use ASME VIII div 1 design code for all our pressure equipments. ASME is one of the oldest standards-developing organizations in America. It produces approximately 600 codes and standards covering many technical areas, such as fasteners, … [Read more...] about ASME – American Society of Mechanical Engineers
PED – Pressure Equipment Directive
PED – Pressure Equipment Directive (2014/68/EU) applies to the design, manufacture and conformity assessment of stationary pressure equipment with a maximum allowable pressure greater than 0,5 bar. The directive entered into force on 20 July 2016.The Pressure Equipment Directive aims to … [Read more...] about PED – Pressure Equipment Directive
