Characterization and Purification of Surfactant Sodium Ligno Sulfonate (SLS) From Biomass Waste in The Application Of Enhanced Oil Recovery (EOR)

Abstract

The waste of pulp and paper industry in the form of Black Liquor still contained a large amount of lignin (12-46%). The high lignin content had the potential to make Sodium Ligno Sulfonate (SLS) Surfactants by reacting Lignin with Sodium Bisulfite. Isolation of Lignin From Black Liquor was carried out at room temperature of 30°C, using sulfuric acid (H2SO4) and 1N NaOH. The purpose of this study was to characterize SLS formed both physically and chemically. Characteristics of SLS were formed compared to commercial SLS. The SLS purification results were carried out by comparing the SLS results of the experiments with commercial SLS using Fourier Transform Infra Red (FTIR) equipment, and the purity was tested by UV-Vis. For Enhanced Oil Recovery (EOR), SLS was tested based on its characteristics using screening tests.

Synthesis and performance evaluation of polymeric surfactant from rice husk and polyethylene glycol for the enhanced oil recovery process

“…As a result, the IFT value is reduced. Priyanto et al [9] explained that the IFT value could be reduced by increasing the hydrophilicity of surfactants.…”

“…SLS molecule has the hydrophobic and hydrophilic parts, which are associated with the aromatic skeleton and sulfonate group, respectively [6]. Pramudono and co-workers [3,[7][8][9] have intensively developed SLS surfactants for the EOR process from biomassbased lignin. Priyanto et al [9] synthesized SLS from black liquor for the EOR process.…”

“…Pramudono and co-workers [3,[7][8][9] have intensively developed SLS surfactants for the EOR process from biomassbased lignin. Priyanto et al [9] synthesized SLS from black liquor for the EOR process. They reported that the SLS surfactant could decrease the IFT value of oil and water up to 0.0254 dyne/cm at an SLS concentration of 0.5%wt in a brine solution of 3000 ppm.…”
