In this study the BPHE is suggested to replace the PFHE to simplify or even omit the massive CO2 purification equipment for the LNG process.
Both groups are alarmed about the lack of practical remedies to deal with coal's massive CO2 emissions.
Phillips, R. J. et al. Massive CO2 ice deposits sequestered in the south polar layered deposits of Mars.
However, public interest (or fear as that) is more related to massive CO2 discharge at the surface and possible affects on human health and the environment.
Petersen's paper ties the first warming spike and extinction to the beginning of the Indian Deccan eruptions, with massive CO2 emissions concentrated in a timeframe of less than 200,000 years, before the asteroid impact.
Massive CO2 injection into subsurface formation involves interactions among pressure and temperature change, chemical reactions, solute transport, and the mechanical response of the rock; this is a coupled thermal hydraulic mechanical chemical (THMC) process.
