BPP-Bubblepoint pressure apparatus


The BPP apparatus has been designed to quickly determine the pressure-volume curve as well as the bubble point pressure of hydrocarbon samples at reservoir representative temperatures and pressures. It is also the ideal tool to perform a quality check on separator samples. The sample cell consists of a stainless steel, high-pressure vessel equipped with a floating piston to separate the hydraulic and separator fluids. On the sample side, the cell incorporates a low dead volume mixer for proper and efficient agitation. The sample volume is measured by tracking the floating piston’s position by means of a position sensor located at the hydraulic end of the cell. An electric heater enables homogeneous temperature control within the cell. Fluid pressurization is attained via an external pressure generator system.
