The utilization of ionic liquids as additives in mud system to improve the rheol. properties for drilling hydrate sediments has received much attention recently. However, their performance needs to be compared with com. inhibitors to effectively enhance their replacement process. Therefore, in this work, the effect of one of the best reports ionic liquid, Tetrametylammonium chloride (TMACl) was used for hydrate management in the drilling process and was compared with PolyvinylPyrrolidone (PVP -a com. hydrate additive). The experiments were achieved by formulating drilling fluid with the compositions of freshwater, 3.0 wt% NaCl, 3.0 wt% KCl and 0.8 wt% Xanthan Gum and 1 wt% of TMACl/PVP, and verifying the rheol., physiochem., and hydrate inhibition properties of the mud system prepared A kinetic hydrate reactor is used to examine the hydrate inhibition properties at 8 MPa and -2°C and a TA instrument rheometer DHR1 was used to study the rheol. properties of the mud systems prepared The results showed that TMACl stabilized drilling mud thermal degradation by 400%, which PVP doubles the thermal degradation rate of drilling mud. In addition, TMACl could provide suitable shear thinning behavior than PVP. Though the effect of both PVP and TMACl on the CH4 hydrate formed is within the same range, PVP delayed the time taken for hydrate formation by 25% from TMACl. Therefore, the findings in this study provided guidelines and information to the successful application and replacement of conventional hydrate inhibitions with ionic liquids This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0COA of Formula: C4H12ClN).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.COA of Formula: C4H12ClN
