Mini-review on Recent Advances in the Application of Surface-Active Ionic Liquids: Petroleum Industry Perspective

Abstract

Ionic liquids have emerged as a promising new material for a wide range of industrial applications, because of their unique structures and properties. Ionic liquids possess exceptional properties such as chemical and thermal stability, negligible vapor pressure, or solvency power for different types of molecules. Ionic liquids find their application in different operations in petroleum industry. The purpose of this paper is to review previously published works on the application of the IL in various areas of the petroleum industry and related processes. A detailed discussion of various processes such as enhanced oil recovery, drilling fluids, gas hydrate, CO2 capture, and flow assurance has been provided. This in-depth discussion is intended to aid professional and researchers in understanding the present condition and planning for the future.

Design of sustainable ionic liquids based on l-phenylalanine and l-alanine dipeptides: Synthesis, toxicity and biodegradation studies

“…Microbial toxicity screening results indicated that none of the tested compounds would be expected to show inhibition towards microbes in inoculum during CBT. Thus, based on results from antimicrobial activity testing all six IL parent compounds (1)(2)(3)(4)(5)(6) and their PTPs (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) were given equal priorities for further studies and were tested for their aerobic biodegradability. Biodegradation testing was performed using modified CBT method and each test ran for up to 33-42 days.…”

“…For specific proposed breakdown pathways for 1-6, see ESI-1. Biodegradation graphs for amino acid ILs (1 and 2) and their PTPs (7-13) and dipeptide ILs (3)(4)(5)(6) and their PTPs (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) are shown on Figs. 2 and 3.…”

“…Biodegradation was evaluated using the monoamino acid ILs (1 and 2) as well as dipeptide ILs (3)(4)(5)(6) and their PTPs (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). In regular CBT conditions with 28 days, 3 and 4 passed the 60 % threshold and could be classified as biodegradable (see Fig.…”

“…In addition to research, ILs are used in applied industrial processes [4,5]. For example, the BASIL TM process used for the production of photoinitiator precursor alkoxyphenylphosphines and the Dimersol process for dimerisation of alkenes and butenes to more valuable branched hexenes and octenes [5][6][7][8][9][10].…”

Review on Applications of Ionic Liquids (ILs) for Bitumen Recovery: Mechanisms, Challenges, and Perspectives

“…4 More so, the world energy supply is being continually dominated by liquid hydrocarbon oil and gas resources. 48 Accordingly, as seen in Figure 2, unconventional resources including tight oil, natural gas liquids, and heavy/extra-heavy oil (bitumen) constitute significant contributors in the liquid fuel supply chain in the present and projected periods. 83 Heavy oil including bitumen represents a huge hydrocarbon energy resource with over six trillion barrels deposited in several places around the world.…”
