WebJun 18, 2010 · The present work investigates hydrate equilibrium conditions for tetra-n-butyl ammonium bromide (TBAB) + methane + water mixtures. The experiments are carried out in the TBAB mass fraction range of (0.05 to 0.45) and in the pressure range of (0.5 to 7.0) MPa. The experimental results show that the presence of TBAB decreases the formation … WebAbstract. Substantial volumes of methane gas are trapped below the seafloor and in permafrost by an ice-like solid called clathrate hydrate. Global estimates of the methane in clathrate hydrate may exceed 10 16 kg, which represents one of the largest sources of hydrocarbon on Earth.
