The main objective of the present work is experimental investigation of double gas hydrate formation with or without presence of kinetic inhibitors in a flow mini-loop apparatus. For this purpose, a laboratory flow mini-loop apparatus was set up to measure the induction time for hydrate formation and the gas consumption rate when a gaseous mixture (such as 75% C1-25% C3, 25%C1-75% C3, 75%C1-25% i-C4 and 25%C1-75% i-C4) is contacted with water in the absence or presence of dissolved inhibitor under suitable temperature and pressure conditions. In each experiment, water blend saturated with gas mixture is circulated up to a required pressure. Pressure is maintained at a constant value during experimental runs by means of required gas mixture make-up. The effect of pressure on gas consumption during gas hydrate formation is investigated with or without presence of PVP (poly vinylpyrrolidone) and L-tyrosine as kinetic inhibitors at various concentrations.
