Hydrates had been a lengthy-standing issue in the oil and gas sector, causing significant flow assurance problem. It may form obstructions due to the decline in pressure and low temperature in oil and gas pipelines. Its impact can be felt in drilling risers, chokes, killing lines, and preventing blowouts. Hydrate plugging of the pipeline would cost approximately more than $1 million per day. In this work, the development of a local inhibitor for the treatment of hydrate formation in oil and gas pipeline under different conditions were studied using a mini hydrate flow loop. A biodegradable and water-soluble inhibitor (Caricaceae Plant Extract Kinetic Inhibitor, CPEKI) was developed from plant extract of caricaceae plant family that was sourced locally. This was done in order to reduce the cost of importing conventional inhibitors like that of Mono Ethylene Glycol (MEG) and Methanol (MEOH). The experiments were carried out with an initial loop pressure of 150 psi and temperature of 29ºC. Different weight concentration of CPEKI, MEG and MEOH were tested under varying conditions of temperature and pressure. The induction time for hydrate formation and inhibition at different conditions were also recorded. From the results analysis, it was observed that the CPEKI shows a very good inhibitory performance throughout the processes with an optimum concentration of 0.05wt% against MEG and MEOH inhibitors. Similarly, the relationship between pressure and temperature as a function of time also indicates that CPEKI performed very well compared to MEG and MEOH. Consequently, it is confirmed that CPEKI is eco-friendly and cheap and therefore suggested for field trials.
