The mixture of methyl acetate and methanol created a minimum-boiling azeotrope which can be separated by pressure-swing distillation.
Melbourne's weather results from the eastward flow of high-pressure cells separated by low-pressure troughs.
A later theory (Caramazza & Shelton 1998) claimed that animate and inanimate objects are treated by different knowledge systems separated by evolutionary pressure: domains of features pertaining to the recognition of living things, human faces, and perhaps tools may have been singled out as recognition of such entities had survival value for humans.
Galactose, xylose, glycerol, acetic acid and ethanol were separated by high-pressure liquid chromatography (HPLC) (Waters, Milford, MA, USA, or Beckman Instruments, Fullerton, CA, USA) with an Aminex HPX-87H ion exchange column (Bio-Rad, Hercules, CA, USA) at 45°C.
The reaction product was separated by high-pressure liquid chromatography (LC) with a reversed-phase column, and LC/tandem-mass spectrometry was performed with the use of negative ion-electron spray ionisation.
The raw syngas is obtained via staged gasification of biomass, using bubbling fluidized bed technology with secondary agents; then it is cleaned, its hydrocarbon content is reformed, CO content is shifted (WGS) and finally H2 content is separated by the PSA (Pressure Swing Adsorption) unit.
These segments were separated by ultra-high-pressure liquid chromatography to achieve chromatographic separation of the oxidized isomers and provide assessments of solvent accessibility at the level of individual residues, in contrast to the peptide-level resolution typical in most footprinting studies to date.
It is a once-through SG housing both water at high pressure and sodium at low pressure separated by a tube wall.
Another important result shown in Figure 6 is that the seal faces of CS-DGS can be separated by a static seal pressure of 0.4 MPa under spring pressure of 0.04 MPa and 0.06 MPa and correspondingly the film thickness value are 4.7 μm and 1.6 μm.
Then the butanol and MIBK azeotrope was separated by the double effect pressure-swing distillation with the low pressure column performing at 30 kPa and the atmospheric pressure column at 101 kPa.
Sub-fraction N3.7 was separated by MPLC or Medium pressure liquid chromatography (Büchi pump manager C-615) under the following conditions: pressure = 4.6 bar, flow rate = 20 ml/min, time = 20 min, volume collected = 500 ml.
