The “PIK-SOK” core cleaning system (EXTRACTOR)

The PIK-SOK  system is designed to clean the core sample void space from reservoir and process fluids under pressure, toluene, with carbon dioxide dissolved in it. When the pressure in saturation chamber decreases, carbon dioxide is released from toluene and, expanding, displaces contaminated solvent from the samples void space. The extraction efficiency is achieved by repeated “saturation – degassing” cycle until solvent coloring terminated with the samples final drying.

Extraction can be performed both for full-size core fragments, and for core samples of different sizes and shapes; however, there are no restrictions on the minimum and maximum load. The system is equipped with a toluene recovery module and a control unit located in a separate room.
