Removing and selling NGL from the produced gas stream is one on the ways CO 2 enhanced oil recovery projects can improve their economics. These projects involve gas recycling into the reservoir for ...

Based on a presentation to the GPA Europe Annual Conference, Prague, Sept. 21-23, 2011. Operational scenarios for two uses of a new refrigeration process for recovering NGLs from natural gas have ...

In three previous articles, we have presented an overview of CO2 (R-744) as a refrigerant, its applications in industrial refrigeration, and a case study of a CO2 cascade system in a European ...

Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling. The proposed system has so far provided low exergy levels, but its costs are much lower ...

The underlying physics principle of mechanical refrigeration is the first law of thermodynamics. This law states that energy -- or heat in this case -- cannot be created or destroyed, only transferred ...
