High Pressure Microscope LEHPM

The LEHPM is designed to accurately visualise the onset of wax and asphaltene precipitation for pressure and temperature conditions of up to 20,000 psi and 200°C, respectively. The LEHPM can not only detect solid particles but also monitor physical variations of wax crystals and asphaltene solids with changing pressure, temperature, time and chemical inhibitors.

The fluid under consideration is homogenized at the desired conditions in an external PVT cell, the fluid is simultaneously depressurized and extracted from the HPM cell at specified, constant pressure and flow rates. The high resolution LEHPM camera records the flow, and results such as particle size distribution can be interpreted by the provided Vinci software. The LEHPM system can be delivered either as a stand-alone system or as an add-on module to the Fluid Eval system.
