    污油泥是指原油开采和集输过程中产生的油、水、土混合形成的非均质多项分散体系,包括污水沉降产生的油泥、管道泄漏污染产生的油泥、联合站沉淀池产生的油泥等。那么,你知道污油泥处理工艺以及未来的发展趋势吗?

    Oily sludge refers to the heterogeneous multi-disperse system formed by the mixture of oil, water and soil in the process of crude oil exploitation and gathering and transportation, including the oily sludge generated by sewage settlement, the oily sludge generated by pipeline leakage pollution, and the oily sludge generated by the sedimentation tank of the combined station. So, do you know the sludge treatment technology and the future development trend?

   污油泥的危害

     Hazard of oily sludge

   油田含油污泥的理化性质非常复杂,一般含有大量老化原油、蜡、沥青、胶体和固体悬浮物、细菌、盐、酸性气体、腐蚀产物、少量机械杂质等。以及恶臭和有毒物质如苯、蒽和芘。大量的水处理剂,如混凝剂、缓凝剂、洗涤剂、杀菌剂等。是在油田生产过程中添加的,这使得它们难以分离和处理。基于油田含油污泥的危害,国家已将含油污泥列为危险废物(HW08)。

     The physical and chemical properties of oilfield oily sludge are very complex, generally containing a large amount of aging crude oil, wax, asphalt, colloid and solid suspended solids, bacteria, salt, acid gas, corrosion products, a small amount of mechanical impurities. And odors and poisons such as benzene, anthracene and pyrene. A large number of water treatment agents, such as coagulant, retarder, detergent, fungicide, etc. They are added during field production, which makes them difficult to separate and dispose of. Based on the harm of oil sludge, China has listed oil sludge as hazardous waste (HW08).

    污油泥处理方法:

    Sludge treatment methods:

    传统上,污油泥处理一般没有直接填埋法(将油泥直接填埋到专业污泥仓库中,然后填满土方,返回原始地形,以这种方式处理油泥,不会暴露在地面上,降低对大气的影响)、注入法(通过相应的钻井设备向地面注入油泥,减少污染)、固化剂、固化油土反应进行固化处理等。上述处理办法未从根本上对污油泥中的有害物质进行处理,一方面经处理后的污油泥对土壤、地下水等仍存在潜在的风险,另一方面会导致污油泥中的石油资源浪费。

    Traditionally, sludge treatment generally does not have the direct landfill method (the sludge is directly buried in a professional sludge warehouse, and then filled with earthwork, return to the original terrain, in this way to treat the sludge, will not be exposed to the ground, reduce the impact on the atmosphere), injection method (through the corresponding drilling equipment to inject sludge into the ground, Reduce pollution), curing agent, curing oil soil reaction for curing treatment. The above treatment methods do not fundamentally treat the harmful substances in the sludge. On the one hand, the treated sludge still has potential risks to soil and groundwater, etc., and on the other hand, it will lead to the waste of oil resources in the sludge.

    根据相关法律法规规定的油气田污油泥处理方法及工艺,包括常温溶剂萃取、化学热洗、焚烧、热裂解。

    According to the relevant laws and regulations of oil and gas field sludge treatment methods and processes, including normal temperature solvent extraction, chemical hot washing, incineration, thermal cracking.

    常温溶剂萃取技术是指在常温条件下利用溶剂分离物理深度,回收矿油、主要浮选泥浆化学剂等有机钻井液,进行运土无害化处理的过程。

    Normal temperature solvent extraction technology refers to the process of extracting organic drilling fluids, such as mineral oil and main flotation mud chemicals, by using solvent to separate physical depth at normal temperature.

    化学热洗处理是指通过化学药品和热水共同作用于含油污泥,降低粘度,实现油、水、固体三相分离的处理过程。

    Chemical hot washing treatment refers to a process in which oil, water and solid are separated by chemical and hot water to reduce the viscosity of oily sludge.

    焚烧处理是在高温和富氧条件下充分燃烧和完全分解含油污泥的过程。

    Incineration treatment is a process of full combustion and complete decomposition of oily sludge under high temperature and oxygen-rich conditions.

    热解处理是指含油污泥在氧气高温下经过蒸馏、热解、缩合等过程转化、分离、回收,实现污泥资源化、减量、无害化的过程。

    Pyrolysis process refers to the transformation, separation and recovery of oily sludge through distillation, pyrolysis, condensation and other processes under high temperature oxygen, so as to realize sludge resource recovery, reduction and harmlessness.

    污油泥处理工艺发展趋势

    Development trend of sludge treatment technology

 各种污油泥处理工艺的效果、成本、资源化程度综合决定了各种工艺在污油泥处理领域的发展趋势。

    The effect, cost and resource recovery of various sludge treatment processes determine the development trend of various technologies in the field of sludge treatment.

综上所述,利用热解技术和设备污油泥处理是实现有机废弃物无害化、减量化、资源化处理的有效途径,具有成本低、效果好、回收大部分油品的特点。

In conclusion, using pyrolysis technology and equipment to treat oily sludge is an effective way to realize harmless, reduction and resource treatment of organic waste, which has the characteristics of low cost, good effect and recovery of most oil products.
