超临界水氧化是一项对有机废液焚烧处理最有潜力的替代技术,在过去的20多年里,这项技术引起了广泛的关注。然而,作为一项管端技术,超临界水氧化仍存在许多不足,这些不足阻碍了它的工业应用。除了反应器腐蚀和盐析导致的技术问题外,超临界水氧化经常被认为是一项处理所有废液的“通用”技术,然而也是无法实现的“通用”技术。本文介绍了作为管端处理技术的超临界水氧化技术存在的问题,讨论了可能的解决办法,介绍了不同反应器的概念,提出了在超临界水氧化领域里开展进一步研究和发展新工艺流程的建议。此外,评价了超临界水氧化技术涉及到的自身能源供应问题。 相似文献

钻井液的使用和钻屑的管理 总被引:1,自引:1,他引:0
澳大利亚矿产和能源部(DME)根据所处地区的环境敏感性、钻屑处置方式和钻井液的环境性能评估钻井液的使用及其废物排放。环境性能的标准包括基液和整个钻井液的生物毒性、可生物降解性和生物累积性。申请人有责任明确活动的环境领域和可能的环境影响。油基钻井液(OBF)的芳烃含量不超过1%,附在钻屑上的基液干重限值为10%。大钻屑堆可能是海洋低水平烃类渗漏到海洋环境的来源之一,对钻屑堆的移除和处置问题,需要慎重考虑。 相似文献

Substantial improvements in residential energy efficiency are required if the UK is to meet its target of reducing CO 2 emissions by 20% between 1990 and 2010. The Home Energy Conservation Act 1995 (HECA) devolves much of the responsibility for this to local authorities, by requiring them to draw up strategies to increase energy efficiency in this sector by 30% in the next 10-15 years. While many authorities have responded positively to the Act, others are struggling, and 25% of HECA reports initially failed to meet the Act's statutory obligations. The Association for the Conservation of Energy (ACE) conducted research to identify barriers faced by local authorities in implementing HECA. They were found to include officers' lack of experience, their lack of time and a lack of support from elected members. Action must be taken to ensure that HECA achieves its potential. The authors suggest that the Act needs to be adequately supported by central legislation, and that devolution of responsibility must be accompanied by some devolution of finances. The authors also recommend that the Act could be used as an example for international replication. 相似文献

总结了涪陵页岩气田开发初期钻井岩屑采用固化填埋方式处置存在占地面积大且易产生二次污染隐患等问题,因地制宜地探索钻井岩屑的资源化利用。分析了水基岩屑随钻预处理和油基岩屑热脱附技术,结合钻井岩屑的理化性质,开展了水基岩屑脱水后干渣制路基材料、制砖及水泥窑协同处置,油基岩屑灰渣制混凝土、制砖及水泥窑协同处置的探索和实践,基于环境安全、技术稳定可靠、消纳量大的原则,最终形成了涪陵页岩气田钻井岩屑资源化方案:水基岩屑"随钻预处理、水泥窑协同处置",油基岩屑"热脱附、水泥窑协同处置",实现了钻井岩屑的资源化综合利用。 相似文献

废混油钻井液资源化利用技术研究 总被引:1,自引:0,他引:1
废钻井液是钻井作业中主要污染源之一,其中含有重金属、碱、盐、油、有机物等多种污染物质,特别是废混油钻井液,油含量更高,是较难解决的问题之一,也是制约油田企业环境质量提高和可持续发展的一大难题。以废钻井液处理为代表的资源化利用技术可有效治理井场废物,将处理后的废钻井液直接用来做井场围堰和平整地面的材料,既可有效地利用废物,消除污染源,又可缓解因污染引起的工农矛盾,减少由钻井开发引发的污染赔款,实现社会效益、经济效益和环境效益的统一。 相似文献
