Gas dense technology PDF Print E-mail
Sunday, 31 May 2009 06:19

For dense gas we means a fluid in supercritical state (SCF). It is a fluid (typically CO2 - carbon dioxide) with low molecular weight having a critical temperature close to ambient temperature (TC ~ 10 ÷ 40 º C) and a critical pressure is not too high (PC ~ 40 ÷ 60 bar).

The light hydrocarbons having these physical properties but have the problem and toxicity. Certain chlorofluorocarbons lend themselves to relatively expensive but are obtained at high purity and are now banned for environmental acceptability.

Carbon dioxide, although a slightly higher critical pressure (PC = 72.1 bar), offers other attractive properties that make it more fluid used in applications:

  • environmental acceptability;
  • nontoxic;
  • low cost at high purities for the possibility of continuous recycling of gas;

5001 SFE plant PDF Print E-mail
Sunday, 31 May 2009 06:37

The implant 5001 has a 5 litres autoclave, operating at 350 bar. E 'equipped with a PLC and a PC for control and supervision of the work cycle. And 'capable of operating cycles of extraction and fractionation cycles, with a column of 2.5 meters. It 'an ideal machine to conduct tests and tests on liquid and solid matrices. The basket 5 litres can evaluate the kinetics with great degree of assurance regarding the scalability for industrial plants. Has a pump for 35 kg / hour for the flow of CO2 and a pump 5 litres/hour for the fluid to be split

This is lab scale plant offering 1000 cc capable extractor at 400 bar operating pressure. Is equipped with a fractionating column of 200 cm and two high pressure diaphragm pumps. The dimensions are very small 140 x 160 cm. 6 gauges on board for the immediate control of the conditions of pressure and 6 digital thermometers to monitor temperatures. The plant is equipped with PLC and supervisor PC monitor with all process parameters. The plant was built by SEPARECO society.

 
5002 SFE plant PDF Print E-mail
Sunday, 31 May 2009 06:46

The 5002 plant has a higher capacity then model 5001. It is a system with 20 litres drum with a diaphragm pump of 80 kg/hr and a fluid pump 20 litres/hr. Can work at 350 bar. The machine is servo PLC and operator station supervisor, from which you can set and test each parameter during the process. The plant is equipped with gravimetric and cyclonic separator for separating heavier and lighter fractions. The column has a height of 7 meters divided into several sections to facilitate the internal circulation of fluid. With this system you can plan samples or pre set to run significant tests before beginning commercial production. On the synoptic panel are visible all temperature, pressure and flow CO2/fluid be split.

 
Micronization PDF Print E-mail
Saturday, 30 May 2009 10:36

Several studies have been conducted over the past several decades to develop techniques that allow the recrystallization of one or more substances by means of a supercritical fluid.
The micronization system will be engineered by Separeco, allows for the recrystallization of substances of interest using the supercritical fluid as solvent, a basic principle of classical techniques GASP (Gas Anti-Solvent Recrystallization). GASP in the supercritical fluid is added to a solution of solute dissolved in organic solvent, the supercritical fluid causes an expansion of the solvent and therefore lower the density of the solution lowering the solvent power of organic liquid and precipitation of the solute.
