Abstract
Abstract Gas hydrates pose a very serious flow assurance problem by impeding flow especially in the offshore environment where accessibility is restricted. This paper takes a look at gas hydrate inhibition in a simulated offshore environment using plant extract (PE) as local inhibitor. The essence of this work is to source for an effective and bio-degradable gas hydrate inhibitor from locally sourced materials and also ascertain their effectiveness as compared to a conventional hydrate inhibitor Mono ethylene glycol (MEG). Experiments were conducted using a mini flow loop. It will involve mitigating hydrate formation using varying weight percentages of the inhibitor (1wt%, 2wt% and 3wt %) and then evaluate their effect on hydrate inhibition in the mini flow loop. Sensitivity charts of pressure, temperature, time for both the local inhibitor and MEG were made. From the analysis, 1 and 2 weight percentages of the local plant extract (PE) showed better inhibitory capacity than MEG while 3 weight percentages of plant extract (PE) and MEG had a close match. Based on the result gotten, the PE could be recommended for field trial.
