Technology development for treating sulfolane impacted soils and water

环丁砜是一种高极性的水溶性无色有机溶剂，广泛应用于天然气加工厂和石油炼制操作中。处置区的沥滤液、加工过程中的泄漏和生产威尔斯井的渗漏导致天然气加工厂周围的土壤和地下水受到广泛的环丁砜污染。据报告，加拿大、澳大利亚和美国的不同地点都存在环丁砜污染。该项目的目标是开发处理以下问题的技术：（a）环丁砜污染的水;（B）环丁砜污染的土壤。这些技术必须是有效的、可现场部署的和可扩展的，从而产生可以返回现场的清洁沃茨和土壤。关于（a）项，将开始研究使用不同的先进氧化方法降解水中的环丁砜，确定反应动力学、中间体和最终产品以及环丁砜吸附到已知吸附剂上的情况。将对从不同地点收集的掺加沃茨和样品进行测试。对于（B），将考虑三种广泛的选择：（一）通过添加氧化剂处理受环丁砜影响的土壤，（二）土壤清洗，然后用（a）中确定的技术处理清洗水，（三）生物修复并将其与高级氧化相结合。根据实验结果，并考虑到现场应用，将开发一种处理土壤中环丁砜的技术。（a）和（B）的结果将用于实验室规模处理系统的设计、制造和测试。作为最后一步，将在我们的模块化设计的中试规模土壤处理系统中进行大规模测试，该系统安装在拖车上的45英尺海罐中。该项目得到了两家加拿大公司的支持-一家石油和天然气生产商和一家补救咨询公司，确保成功的结果可以立即转化为处理受污染的沃茨和土壤。除了提供一个更清洁、更健康的环境外，该项目还将导致为一个全球性问题制定加拿大的解决办法，从而为加拿大公司提供机会。

Sulfolane, a highly polar water miscible and colorless organic solvent, is used extensively in natural gas processing plants and petroleum refining operations. Leachates from disposal areas, leaks during processes and seepage from producing wells have led to extensive sulfolane contaminated soil and groundwater around gas processing plants. Sulfolane contamination has been reported at different sites in Canada, Australia & USA.The goal of this project is to develop technologies to treat: (a) sulfolane contaminated water & (b) sulfolane contaminated soils. The technologies must be effective, on-site deployable & scalable leading to clean waters and soils that can be returned to site. For (a), studies on degradation of sulfolane in water using different advanced oxidative methods, identification of reaction kinetics, intermediates & end products as well as sulfolane adsorption onto known adsorbents, will be initiated. Tests will be conducted on both spiked waters & samples collected from different sites. For (b), three broad options will be considered: (i) treatment of sulfolane impacted soils by adding oxidants, (ii) soil washing followed by treating the wash water with technologies identified in (a) and (iii) bioremediation and combining it with advanced oxidation. Based on experimental results, and upon considerations of field applications, a technology for treating sulfolane in soils will be developed. The results of (a) and (b) will be advanced into the design, fabrication and testing of bench scale treatment systems. As a final step, large scale testing will be conducted in our modularly designed pilot scale soil treatment system, housed in a trailer mounted 45 foot sea-can.The project is being supported by two Canadian companies-an oil & gas producer and a remediation consulting company, ensuring that successful results can be immediately translated to treating contaminated waters and soils. In addition to providing a cleaner healthier environment, this project will lead to the development of a Canadian solution to a global problem thus providing opportunities to Canadian companies.
