effect of solution gas oil ratio on Screw Pump efficiency
effect of solution gas oil ratio on Screw Pump efficiency
(OP)
i want to ask about the effect of increase solution gas oil ratio (amount of gas dissolved in the oil) on Screw Pump efficiency used to transfer crude oil , and if this can increase clearances between the rotor and pump housing
and what the other bad effect of increased gas dissolved in the oil on the Screw Pump
and what the other bad effect of increased gas dissolved in the oil on the Screw Pump





RE: effect of solution gas oil ratio on Screw Pump efficiency
If there is more gas dissolved, but you are operating at the inlet side above the partial pressure of said gas ( i.e. above bubble point) then the only big issue would be that the density should decrease and possibly viscosity as well, but otherwise you're still pumping a liquid so there should not be any significant change.
If you're below bubble point a the inlet then you're looking at a two phase pump and all hell will break loose.
So which is it?

As the pressure increases along the screw the amount of gas will reduce, but the overall liquid flow of your pump will decrease and possibly the pressure able to be output. How much is dependent on the amount of gas actually present in the fluid at the inlet.
