“…The remaining oil in the reservoir can be removed and produced to increase oil recovery. Processing of bagasse into SLS surfactant is carried out through two processes, namely hydrolysis and sulfonation [80][81][82]. Hydrolysis is the separation of lignin from bagasse by using a sieve analysis to obtain a size of 80 mesh.…”

Anionic surfactants are generally used in surfactant injections because they are good, resistant in storage and stable. Furthermore, Commercially, anions are produced in the form of carboxylates, sulfates, sulfonates, phosphates, or phosphonates. The surfactants used in the process of implementing Enhanced Oil Recovery (EOR) are generally petroleum-based, such as Petroleum Sulfonate. Therefore, an increase in oil price, leads to an increase in the price of surfactant and the operational costs becomes relatively expensive. Lignosulfonate is a type of anionic surfactant which is made with lignin as raw material. This lignin is found in many plants, including wood stalks, plant leaves, peanut shells, corn cobs, bagasse, empty bunches of oil palm and wheat straw. Based on the results of previous studies, 25% of lignin component was discovered in bagasse. This may be a consideration that there is enough lignin in bagasse to be used as raw material in the production of lignosulfonate vegetable surfactants. Furthermore, lignin from bagasse is used because bagasse is easy to obtain, cheap and an environmental friendly vegetable waste. Currently, bagasse is only used as fuel in steam boilers and papermaking, cement and brick reinforcement, a source of animal feed, bioethanol, activated charcoal as adsorbent and compost fertilizer. This is a consideration to optimize the use of bagasse to become lignosulfonate as an alternative for surfactants in the petroleum sector. The purpose of this study is to show that lignin from bagasse has the potential of becoming a lignosulfonate surfactant. There are several studies that have processed bagasse into sodium lignosulfonate. The component test on the results showed that the surfactant component of sodium lignosulfonate from bagasse was almost the same as the commercial standard lignosulfonate component. Furthermore, the results of the HLB (Hydrophilic–Lipophilic Balance) value test show that the sodium lignosulfonate surfactant from bagasse can function as an emulsion form which is a required parameter for the surfactant injection mechanism. Based on the discussion of the study results, bagasse has the potential as a raw material to be processed into lignosulfonates.

A study on the polyvinylidene fluoride (PVDF) membrane using lignin and lignosulfonate oil palm empty fruit bunch (OPEFB) fillers have been carried out. This study aims to determine the additional effect of lignin and lignosulfonate on PVDF membrane. Lignin sulfonation has a good result proven by Fourier transform infrared spectra with a peak at 1192 cm−1 which indicates sulfonate group. The sulfonation degree was increased by 8.9% for lignosulfonate. The membrane was prepared by the phase inversion method. Data present that all the membranes have an asymmetric structure with finger-like and sponge-like pores. Good thermal stability indicated by thermal gravimetric analysis showed degradation at 432 °C. The mechanical properties of the membrane decrease with the addition of filler. From the X-ray diffraction, peaks appeared at 18.39°, 21.35°, and 23.75° for all the membranes indicating of α and β phases. Lignin and lignosulfonate increased membrane hydrophilicity and water uptake. The presence of the sulfonate group increases the ionic exchange capacity and ionic conductivity up to 2.78 mmol/g and 9.95 × 10−5 S/cm, respectively, for 5% lignosulfonate addition. Thus, PVDF/lignosulfonate has the potential as a polymer electrolyte membrane.
