一、含油污泥处理
I. Oily sludge treatment

含油污泥的产生
Production of oily sludge

石油在采油、管道输送、油气联合站、炼油厂、含油废水等处理过程中产生的含油污泥
Oily sludge produced by petroleum in oil production, pipeline transportation, oil-gas combined stations, oil refineries, and oily wastewater.

油泥处理是一个成套的生产工艺,利用的是氧化破乳和离心分离原理,主要设备是由加药系统、进料系统、分离系统、输送系统、控制系统等组成
Sludge treatment is a complete set of production process, using the principle of oxidative demulsification and centrifugal separation. Its main equipment is composed of dosing system, feeding system, separation system, conveying system, and control system.

将含油污泥收集后通过蒸汽加热的方式,添加合适地破乳剂、活性剂等,使得处于乳化状态的油水实现破乳,破乳后的含油污(废)水采用高效LWS系列三相离心机进行油++渣的三相连续分离,经离心机分离后的水和未破乳的油水混合液直接交污水处理系统进行处理,可采用高效脱水的LW系列二相离心机完成这项脱水任务,脱水后的渣相可采用燃烧或热脱附工艺回收残留原油,分离后的粗油经收集,再采用三相碟片离心机予以提纯,经过提纯后的油可实现再利用。
After the oily sludge is collected and heated by steam, a suitable number of additives like demulsifier and active agent are added in it, so that the oily water in the emulsified state is broken. After demulsification, a high-efficiency LWS series three-phase centrifuge is adopted to realize the continuous separation of oil, water, and slag in the oily sludge, and the water separated and the oil-water mixture not demulsified are directly sent to the sewage treatment system for treatment. Then, a LW series two-phase centrifuge with high efficiency is used for dehydration. The crude oil residue in the dehydrated slag phase can be recovered by the combustion or thermal desorption process. The separated crude oil is collected and then purified by a three-phase flottweg separator. The purified oil can be reused.

二、含油污(废)水处理
II. Oily (waste) water treatment

目前针对炼化厂在加工原油的过程中产生的油污(废)水,往往采用粗犷式絮凝+脱水的处理模式,脱水后渣相直接采用焚烧处理,这种处理模式,造成原油资源的浪费,现在我们可以通过一系列预处理(添加破乳剂、表面活性剂等)后采用高效LWS系列三相离心机,实现原油的再次资源化利用
At present, the oily (waste) water generated in the course of processing crude oil in the refinery is often treated by rough flocculation + dehydration. The slag phase is directly incinerated after dehydration. This treatment mode causes waste of crude oil resources. Now we can apply a series of pretreatment processes (adding demulsifier, surfactant, etc.) and then use the high-efficiency LWS series three-phase centrifuge to realize the reuse of crude oil resources.

将含油污(废)水收集后,添加合适地破乳剂、活性剂等,使得处于乳化状态的油水实现破乳,破乳后的含油污(废)水采用隔油池进行自然沉降分离,隔油池中间层的水和未破乳的油水混合液直接交污水处理系统进行处理,可采用高效脱水的LW系列二相离心机完成这项脱水任务上浮于隔油池的上层浮油和沉降于底层的污泥,收集汇总后进入搅拌罐进行进一步处理处理后的油污泥可采用高效LWS系列三相离心机进行油 ++渣的三相连续分离。
After the oily (waste) water is collected, a suitable amount of demulsifier, an active agent, etc. are added, so that the oily water in the emulsified state is broken, and the oily (waste) water after demulsification is naturally settled and separated in an oil trap. The water in the middle layer of the oil trap and the oil-water mixture not demulsified are directly sent to the sewage treatment system for treatment. The task of dehydration can be completed by the high efficiency LW series two-phase centrifuge. The oil floating on the upper layer of the oil trap and the sludge settled on the bottom layer are collected and sent into the stirring tank for further treatment. The oil, water, and slag in the oily sludge treated can be separated continuously from each other through the high-efficiency LWS series three-phase centrifuge.

对于处理油污(废)水,其目的是为了回收更多的油,降低固体中的油含量,因而整套工艺系统中的各工段的作用都显得非常的重要.
For the treatment of oily (waste) water, the purpose is to recover more oil and reduce the oil content in the solid. Therefore, the role of each section in the whole process system is very important.

Oilfield drilling requires drilling oil-based mud according to the drilling depth and geological conditions. The mud's basic composition is oil, water, organic clay, and oil-soluble chemical treatment agent. OBM resists high temperature and calcium salt erosion, which is beneficial to the stability and lubrication of the well wall. The mud features good performance and small damage to oil and gas layers, and wide application in various types of drilling platforms. However, the slag generated in the equipment of drilling solid control system (vibrating screen, centrifuge, and dryer) has seriously affected the environmental safety and must be treated in a harmless manner. After treatment, the oil content of the slag is less than 1% and the oil is further purified and reused.

将收集的钻井油基泥浆固废用水按比例进行高速搅拌制浆,添加合适地破乳剂、活性剂等,使得处于乳化状态的油水实现破乳,在进入分 离前,箱采用振动筛通过籯动筛选,除去混杂其中的大顆粒泥土、砂石、玻璃瓶、矿泉水瓶、方便袋、纱布等生活垃圾及其它固体废弃物,而后采用高效LW系列二相离心机进行(油++渣的二相连续分离,经分离后的液相采用蒸汽加热后,进入沉降槽,撇去上清液,将沉降于底部和离心机分离后渣相混合后采用热脱附工艺回收残留油
The collected drilling OBM solid wastewater is subjected to high-speed stirring in proportion, and a suitable amount of demulsifier, active agent, and other additives are added, so that the oily water in the emulsified state is broken. The vibrating screen is used before separation to remove large particles of soil, sand, glass bottles, mineral water bottles, convenient bags, gauze, and other solid wastes, and then the high-efficiency LW series two-phase centrifuge is adopted to separate continuously the (oil + water) + slag. After heated by steam, the separated liquid phase enters the sedimentation tank, in which the supernatant is removed, and the liquid phase settled at the bottom of the tank is mixed with the slag phase separated by the centrifuge. The residual oil is recovered by the thermal desorption process.

落地油泥的产生
 Production of ground sludge

在石油开采过程的钻井和试喷过程中有大量原油降落地面与泥土、砂石、水等物质混合后形成油土混合物称之为落地油泥根据落地原油的性质可将油泥分为稠油泥和稀油泥还可根据油泥堆放时间的长短可将其分为新鲜油泥和积存油泥落地油泥的含油率一般可在10~30%。由于在采油现场各种生活垃圾应有尽有,导致油泥中除泥土、砂石外,还混杂有玻璃瓶、矿泉水瓶、方便袋、纱布等生活垃圾及其它固体废弃物。
During the drilling and test spraying of the oil exploitation process, a large amount of crude oil falls to the ground and is mixed with soil, sand, water, and other substances to form an oil-soil mixture, which is called ground sludge; according to the nature of the crude oil, the sludge can be divided into heavy sludge and thin sludge; according to the storage time, it can also be divided into fresh sludge and accumulated sludge. The oil content of the ground sludge can generally be 10~30%. Because there are all kinds of domestic garbage at the oil production site, the sludge, in addition to soil and sand, is mixed with other domestic wastes and solid wastes like glass bottles, mineral water bottles, convenient bags, and gauze.

油气站罐底油泥的产生
 Production of sludge at the tank bottom of the oil-gas combined station

原油在油气站储罐中被长时间存储时,原油中的高熔点蜡、沥青质、胶质和所夹带的泥砂等无机杂质就会和水一起变成沉淀物,在储罐底部形成含油污泥,减少储罐的有效容积,这部分油泥称之为油气站罐底油泥。
If crude oil is stored for a long time in the tank of the oil-gas combined station, the inorganic impurities such as high melting point wax, asphaltene, colloid, and entrained mud and sand in the crude oil will become precipitates together with water, forming oily sludge at the bottom of the tank so as to reduce the effective volume of the tank. And such sludge is called sludge at the tank bottom of the oil-gas combined station.

沉淀池含油污泥的产生
