Advantages and Application
The Supersonic Gas Separator recovers part of the pressure drop needed for cooling and as such has a higher efficiency than a JT valve in all conditions of operation.
The Supersonic Gas Separator can in many cases have a 10 - 20% higher efficiency than a Turboexpander.
The Supersonic Separator has a smaller footprint and a lower weight than a Turboexpander or Contactor columns. This is of particular advantage for platforms, FPSOs and crowded installations. It needs a lower capital investment and lower operating expenditure as it is completely static. Very little maintenance is required and no (or greatly reduced) amounts of chemicals.
The fact that no operational or maintenance personnel is required might enable unmanning of usually manned platforms with the associated large savings in capital and operational expenditure.
The fields of application commercially developed until today on an industrial scale are
-
- dehydration
- dewpointing (water and/or hydrocarbons)
- LPG extraction
Applications in the development stage for near term commercialization are
-
- CO2 and H2S bulk removal

Famous quotes containing the words advantages and/or application:
“... is it not clear that to give to such women as desire it and can devote themselves to literary and scientific pursuits all the advantages enjoyed by men of the same class will lessen essentially the number of thoughtless, idle, vain and frivolous women and thus secure the [sic] society the services of those who now hang as dead weight?”
—Sarah M. Grimke (1792–1873)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
