Extracting and separating solid particulates from a drilling fluid includes combining a stream of drilling fluid containing solid particulates with a liquefied gas to form a mixture having a reduced viscosity and/or density. The mixture enters a centrifugal separator at a pressure sufficient to keep the liquefied gas in a liquid phase where rotational forces promote the separation of at least a portion of the solid particulates from the mixture. At least a portion of the solid particulates are removed to form a fluid stream having reduced solids content. In embodiments the liquefied gas can be selected from the group consisting of an inert gas, an alkane gas, an alkene gas, an alkyne gas, a noble gas, and combinations thereof. The liquefied gas can be removed from the fluid stream after the centrifugal separator and recycled back to be mixed with the stream of drilling fluid containing solid particulates.

Method and apparatus for centrifugal blood component separation including temperature sensing in each of a plurality of separation cells. The temperature of unit of bloods over time is recorded. If the temperature of any of the units exceeds a pre-determined maximum, portions of the blood separation device may be cooled. A controller may determine which of the units to process first, generally proceeding from the warmest unit to the coolest. The order of unit processing may be changed during processing. The detected temperature may be used to calibrate a pressure sensor used to predict the volume of a component separated from a composite fluid by predicting the volume of the composite fluid from sensed pressure and predicting the volume of other separated components from sensed movement of the other components to collection bags.

One embodiment relates to a pressure sensor apparatus, including a housing with a flexible member and an aperture configured to receive a fluid. The pressure sensor apparatus further includes a first member disposed on the flexible member, a second member removably coupled to the first member configured to move in response to a pressure of the fluid and a sensor configured to detect the movement of the second member. The pressure sensor apparatus generates a pressure signal for the fluid based on the displacement of the second member.
