Discussion on thermal desorption remediation technology with rotary kiln for petrochemical contaminated soil

Research & Development Center of Engineering Technology, Sinopec Engineering(Group) Co., Ltd., Luoyang 471000, China

摘要

摘要: 石油化工污染土壤以有机污染物为主,包括苯系物(BTEX)、多环芳烃(PAHs)、多氯联苯(PCBs)、总石油烃(TPH)等,转窑式热解吸修复技术是适合我国石油化工污染土壤修复的高效技术之一,具有良好的应用前景。主要从技术原理、技术特点、技术分类、尾气处理和影响因素等对该类热解吸修复技术进行了详细分析和探讨。该技术在节能降耗和自主集成开发领域仍有较大的技术提升空间,需对回转窑的高温出土和高温烟气余热进一步加以利用,以提高热效率;同时应加快开发适合我国国情且具有自主知识产权的土壤热解吸修复及尾气处理设备。

Abstract: Organic contaminants, including BTEX, PAHs, PCBs, TPH, etc., are the main pollutants in the petrochemical contaminated soil. Thermal desorption technology with rotary kiln, which has a good application prospect, is an efficient and suitable technology for the remediation of soil contaminated by petrochemical industry in China. The thermal desorption remediation technology was analyzed and discussed in detail from the aspects of technical principle, technical characteristics, technical classification, tail gas treatment and influence factors. The technology still has a space for enhancement in the areas of energy saving and cost reduction and independent integrated development. It is necessary to improve the thermal efficiency by further utilizing the waste heat in the soil and tail gas with high temperature from the rotary kiln. In addition, the development should be accelerated for the soil thermal desorption recovery and tail gas treatment devices which are suitable for China's national conditions and have independent intellectual property rights.
