Synthesis and Characterization O F Sodium Methyl Ester Sulfonate for Chemically-Enhanced Oil Recovery

Abstract

Attention has been given to reduce the cost of surfactant by using castor oil as an alternative natural source of feedstock. A new surfactant, sodium methyl ester sulfonate (SMES) was synthesised using ricinoleic acid methyl ester, which is obtained from castor oil, for enhanced oil recovery in petroleum industries. The performance of SMES was studied by measuring the surface tension with and without sodium chloride and its thermal stability at reservoir temperature. SMES exhibited good surface activity, reducing the surface tension of surfactant solution up to 38.4 mN/m and 27.6 mN/m without and with NaCl, respectively. During the thermal analysis of SMES, a 31.2% mass loss was observed from 70 °C to 500 °C. The phase behavior of the cosurfactant/SMES-oil-water system plays a key role in interpreting the performance of enhanced oil recovery by microemulsion techniques. Flooding experiments were performed using a 0.5 pore volume of synthesized SMES solutions at three different concentrations. In each case chase water was used to maintain the pressure gradient. The additional recoveries in surfactant flooding were found to be 24.53%, 26.04% and 27.31% for 0.5, 0.6 and 0.7 mass% of surfactant solutions, respectively.

Study of Synthesis Polyethylene glycol oleate Sulfonated as an Anionic Surfactant for Enhanced Oil Recovery (EOR)

“…While the mole ratio of 1:0,5, sulfuric acid as sulfonation agent used is not optimal, so iodine value is still high. The highest number of iodine on TM (without methanol) indicates that there are still many reactants that do not react [6,8,18]. In Figure 2, ester value is an indicator of the ester compound.…”

“…On the other hand, the ester value increased with sulfonation reactions. Increasing ester value occurred because of extension chain of reactive carboxyl from PDO [17], it will react with the base which means the residual acid in the anionic surfactant product is reduced [6,8,18]. Babu in his study made sodium methyl ester sulfonate from ricinoleic acid, with the result of acid value, saponification value and iodine value are 10-12, 185-190, and 80-90 respectively.…”

“…Synthesized of a vegetable oil based methyl ester (oleic acid) as a cationic polymeric for EOR applications was performed by Irawan (2015) [7]. Babu (2015) was synthesized an anionic surfactant (sodium methyl ester sulfonate) from castor oil [8]. An anionic surfactant have a negative charge and some properties such as stable, decreasing IFT or interface tension, and low adsorption to The surfactant used depends on conditions and characteristics of the intended reservoirs.…”

Oleochemicals from Palm Oil for the Petroleum Industry

“…Thus, a less hazardous and cost-effective but high performance surfactant formulation for an efficient oil recovery is required. These have led to interest in green and cost-effective processes for the manufacturing of commercial surfactants from sustainable feedstock [21]. Bio-based surfactants, due to their biodegradability and lower critical micelle concentration [22] are therefore becoming more attractive for the application in the petroleum industry [12].…”

A New Gas Chromatography–Mass Spectrometry Method for Detecting and Quantifying Low Levels of Dimethyl Sulfate in Palm Oil‐Based Sulfonated Methyl Esters

“…Introduction α-sulfonated methyl ester (α-SME) is an oleochemicalbased anionic surfactant derived from natural fats and oil resources including tallow, soya, palm oil (Ahmad et al, 1998;Xie et al, 2013), castor oil (Babu et al, 2015;Meshram et al, 2015), and coconut oil. It is made from renewable natural resources and has excellent biodegradability (Ghazali and Ahmad, 2004;Ishak et al, 2016;Masuda et al, 1993Masuda et al, , 1993b.…”
