“…This result suggests that the degradation of sulfolane in the absence of oxygen would not occur to an appreciable extent. The results reported by Greene et al (Greene, et al 1998) were corroborated by the results from other studies which observed that the degradation of sulfolane only took place in the presence of oxygen (Fedorak and Coy 1996) (Yang, Liu, et al 2019) (Kasanke and Leigh 2017). It was also observed that supplementing N and P into the reaction solution significantly accelerated the sulfolane degradation.…”

“…In particular, sulfolane can be released into the environment through improper storage and handling of pure sulfolane solvent, as well as through improper disposal of sulfolane-containing wastes. Sulfolanecontaminated sites were found at gas processing plants, pesticide manufacturing plants, and oil refinery plants in North America, Australia, Taiwan and other countries (Stewart and Minnear 2010), (Yang, Liu, et al 2019). As mentioned earlier, sulfolane is highly soluble in water (essentially miscible with water), non-volatile, and is very hydrophilic.…”

“…The tested solutions include synthetic solutions consisting of 1 mM NaHCO3 (which served as a pH buffer and also as an electrolyte) and sulfolane, and two groundwater samples that were collected from an aquifer in the vicinity of a sulfolane-contaminated site.

Sulfolane (2,3,4,5-tetrahydrothiophene-1,1-dioxide) is an industrial solvent used in a variety of applications including in synthetic chemistry, electric and electrical circuit processing, and in the oil and gas industry. The most popular application of sulfolane is for the extraction of aromatic hydrocarbons and sweetening of natural gas in which sulfolane is mixed with alkanolamines (such as diisopropanolamine) as well as other organic substances. Improper handling, storage, and disposal of pure sulfolane solvent and sulfolane-containing wastes have created contaminated sites where the concentration of sulfolane can be hundreds of mg/L. Sulfolane is miscible with water, non-volatile, does not adsorb to mineral surfaces to an appreciable extent, and does not biodegrade quickly under conditions where nutrients and oxygen are limited. As such, once sulfolane is released into the subsurface it will travel long distances and create large contamination plumes that can be difficult to contain and mitigate. Sulfolane in groundwater systems and private wells have been detected in Canada, the US, Australia, and other countries. While sulfolane's toxicity and the risk that it can pose to human health are not thoroughly understood, residences whose drinking water wells containing detectable levels of sulfolane (0.01 mg/L-1 mg/L) have been put under water advisories. Therefore, there is an urgent need to develop treatment technologies capable of cleaning up sulfolane-contaminated sites and removing sulfolane from drinking water to protect water resources and human health. The overall objective of this research was to investigate the adsorption of sulfolane on a wide variety of natural and synthetic adsorbents, including sand, iron oxide, aluminum oxide, eight types of granular activated carbons (GAC), Ambersorb 560, Optipore L493, silica gel, zeolite, and silica gel. The removal of sulfolane by these materials were xii

BACKGROUND Sulfolane has recently emerged as a contaminant of concern in and around oil and gas processing sites in North America and elsewhere. In this research, a comprehensive laboratory study was conducted to investigate the importance of several factors (nutrient levels, aeration methods and inoculants) involved in aerobic biodegradation of sulfolane in groundwater. The aerobic biodegradation of sulfolane was also evaluated under field conditions, which can provide useful information for future field application. RESULTS A lag period of 40–141 h and a zero‐order rate of 0.6–6 mg L−1 h−1 for sulfolane degradation were observed under different laboratory conditions. The aerobic biodegradation rates observed in the field in Alberta, Canada were 4–6 mg L−1 day−1. A C:N:P ratio of 100:5:1 was determined to be suitable for aerobic degradation of sulfolane. The introduction of sediments from sulfolane‐contaminated sites can shorten the lag period from 141 to 74 h. CONCLUSIONS Sulfolane can be effectively degraded in groundwater using aerobic biodegradation in both laboratory and field conditions. A negative correlation was obtained between adenosine triphosphate and sulfolane concentration when it started to degrade. © 2021 Society of Chemical Industry (SCI).
