Description

一种移动式组合油砂洗涤的方法和装置 技术领域
本发明涉及一种旋流、超声组合式水洗法油砂洗涤的方法和装置，属于石油化工分离领域。
背景技术
据估计，我国原油对外依存度在2020年将达到67.7％，约需年进口石油4.8亿吨。我国原油资源供需存在着巨大的缺口，制约着我国经济的持续健康发展。
油砂，又称沥青砂或焦油砂，是一种含有沥青或焦油的砂或砂岩，属于非常规石油资源，其开发利用都将越来越受到人们的重视。
我国油砂分布广、资源潜力大，其探明储量换算成油砂油，远大于石油的探明储量。过去由于廉价原油的开采及油砂分离成本较高等因素制约下，油砂油产量增长及研究进展缓慢。开发油砂分离新技术，降低油砂分离的能耗和环境污染，增加油砂油的产量，对降低我国的原油对外依存度及能源安全具有重大意义。
油砂油对应于油成分的沥青(bitumen)，以及石英砂(quartz sand)、粘土(clay)、水及微量的各种矿物质以物理化学方式混合在一起而构成，按其储藏位置的不同成分多少会不同，大概由75～85％的无机物(石英砂、粘土、矿物质等)，1～5％的水，1～18％的沥青构成。
另外，由于石油开采在周边形成的落地油，其分布也较广，总量也较大，裸露在环境中，在雨水浸泡下，流入农田、河流，使水中溶解氧得不到补充。同时，石油本身被微生物降解时，要消耗大量氧气，使水体严重缺氧，水生生态系统遭受破坏。许多多环芳烃(PAH)具有致突变和致癌性，通过直接和间接途径对人体健康带来严重损害。某些有害物质进入农田后，被农作物吸收，通过食物链进入人和动植物体内，导致各种疾病发生，威胁人类的健康。因此开发对落地油的再利用的工艺方法具有资源利用和环境保护的双重意义。
油砂、落地油的开发利用主要是利用油砂、落地油制油，其分离方法大体可分为水洗法、溶剂法和裂解法。其中，不论是溶剂法，还是裂解法，都存在工艺流程复杂、设备投资巨大、生产成本高、环保难达标等缺点，而难以实现大规模 工业化生产。水洗法则以其工艺流程简单、设备投资少、生产成本低，而被广泛应用于工业化生产
随着技术的应用和研究的深入，发现旋流分离技术依靠自身结构简单、处理量大、操作成本低的优势在油砂洗涤修复中得到了越来越广泛的应用。移动式组合油砂洗涤是采用旋流分级分离、超声水洗、机械搅拌、温度控制等技术组合使得油与砂的分离，且移动式具有方便移动、灵活操作、节约运输成本等优点，达到油分高效回收、砂土可直接填埋、重金属成分有效去除的目的。
目前国内油砂水洗技术尚无成熟技术，相关实验室研究尚且不多，而且研究重点大多是开发适合于油砂洗涤的表面活性剂，而对于油砂洗涤系统的核心设备及组合优化工艺未见报道。因此，需开发一种适合于我国油砂及落地油性质特点的紧凑高效、低耗便捷的移动式组合油砂洗涤方法和装置。
发明内容
鉴于以上问题，本发明提供了一种利用旋流、超声、机械搅拌、温度控制组合技术进行油砂、落地油洗涤的方法和装置。采用管道过滤器分选出大粒径的杂物或石块，管道混合器加强油砂混合、洗涤，并充分利用旋流分离结构简单、成本低、可靠性高的优点，主要经过一级洗涤、预分离，二级混合、固液分离，三级油水分离，四级泥/砂处理回填。最终实现油与泥/砂的深度分离，达到油的利用、砂或泥的回填，自来水的回用的目的，保证系统紧凑高效、低耗便捷、可移动操作、不造成再次污染。
