石油预处理工艺流程框图The process flow diagram of oil pretreatment is an essential tool in the oil refining industry. It outlines the various steps involved in preparing crude oil for further processing. This diagram provides a clear visual representation of the equipment, piping, and control systems required for the efficient operation of the pretreatment process.石油预处理工艺流程图是石油精炼行业的重要工具。

它概述了为进一步加工石油原油而涉及的各个步骤。

该图提供了用于有效运行预处理过程所需的设备、管道和控制系统的清晰视觉表示。

The first step in the oil pretreatment process is desalting, which involves removing salt and other impurities from the crude oil. This is typically done using electrostatic precipitators or chemical additives to facilitate the separation of the salt from the oil. Desalting is crucial to prevent corrosion in downstream equipment and to improve the quality of the refined products.石油预处理过程的第一步是脱盐，其中涉及从原油中去除盐和其他杂质。

The process flow diagram is a visual representation of these steps, providing a clear overview of the entire production process.The first step in chemical production is the selection and preparation of raw materials. This may involve sourcing and testing raw materials to ensure they meet the required specifications for the final product. Once the raw materials are approved, they are stored in designated areas until needed for production.The next step is the mixing and reaction process, where the raw materials are combined and undergo chemical reactions to produce the desired compounds. This step is crucial in determining the quality and properties of thefinal product. The process flow diagram illustrates the equipment and machinery used in this step, as well as the flow of materials through the production line.Following the mixing and reaction process, the product undergoes purification and separation to remove impurities and isolate the desired compound. This step often involves the use of distillation, filtration, and other separation techniques to achieve the required level of purity.Once the product is purified, it may undergo further processing, such as drying, crystallization, or chemical treatment to enhance its properties. The process flow diagram highlights these additional steps and the equipment involved in each process.Finally, the finished product is packaged and labeled for distribution. The process flow diagram shows the packaging and labeling steps, as well as any qualitycontrol checks that may occur before the product is released for distribution.Overall, the process flow diagram provides a comprehensive overview of the chemical production process, from raw material selection to final product distribution.中文回答：化工生产流程涉及一系列步骤，将原材料转化为有价值的产品。

炼油厂成品油出厂流程英语Finished Product Ex-Refinery Process.The finished product ex-refinery process is the sequence of steps involved in preparing and releasing refined petroleum products from a refinery for distribution to customers. It encompasses a range of activities, including product blending, storage, testing, and loading.Product Blending.The first step in the ex-refinery process is product blending. Here, various refined products are combined to create specific grades and specifications required by customers. For example, different octane-rated gasoline blends are created by mixing components such as straight-run gasoline, reformate, and alkylate. Blending is acritical process that ensures the finished product meets industry standards and end-user requirements.Storage.After blending, the finished products are stored in large tanks to await distribution. These tanks provide temporary storage for various products, including gasoline, diesel, jet fuel, and heating oil. The storage facilities are designed to maintain product quality and prevent contamination.Testing.Before release from the refinery, the finished products undergo rigorous testing to ensure they meet specifications and regulatory standards. This testing includes:Physical property analysis: Measuring parameters such as density, viscosity, and flash point to ensure the product meets industry standards.Chemical analysis: Determining the composition of the product, including the presence of impurities or additives.Performance evaluation: Assessing the product's performance in specific applications, such as enginetesting for gasoline.Loading.Once testing is complete, the finished products are loaded onto various transportation modes for distribution to customers. These include:Trucks: Used for short-haul transportation of products to local distribution terminals or end-users.Railcars: Suitable for larger volumes and longer-distance transportation.Ships: Used for export and import of products to and from international markets.Documentation.Throughout the ex-refinery process, detaileddocumentation is maintained to track the movement and quality of the products. This documentation includes:Product certificates: Official documents that certify the specifications and quality of the finished products.Shipment records: Detailed logs of product loading, transportation, and delivery.Quality control reports: Records of testing results and any deviations from specifications.Quality Control and Assurance.Maintaining the quality of finished products is paramount throughout the ex-refinery process. Refineries implement strict quality control measures, including:Process monitoring: Continuously monitoring process parameters to ensure optimal blending and storage conditions.Regular testing: Performing scheduled testing toverify product quality and compliance with specifications.Equipment maintenance: Ensuring proper maintenance and calibration of storage tanks and loading equipment to prevent contamination.Safety and Environmental Considerations.Safety and environmental protection are integral to the finished product ex-refinery process. Refineries adhere to rigorous safety protocols and environmental regulations to minimize risks and protect human health and the environment. These measures include:Proper handling and storage: Implementing safehandling practices and maintaining appropriate storage facilities to prevent spills and leaks.Waste management: Establishing systems for proper disposal of waste generated during the process.Emergency response plans: Developing and implementing plans to respond effectively to potential emergencies, minimizing impact on the environment and ensuring the safety of personnel.Conclusion.The finished product ex-refinery process is a complex and multi-faceted operation that ensures the safe and efficient release of refined petroleum products from refineries to customers. It involves a series of steps, from product blending and storage to rigorous testing, loading, and documentation. By adhering to industry standards and implementing strict quality control measures, refineries deliver products that meet customer specifications and regulatory requirements. Safety and environmental considerations remain paramount throughout the process, protecting human health, the environment, and the integrity of the products.。

49张化工装置流程图催化分流部分工艺流程图导读：石油化工厂里的装置多种多样，而很多装置作为化工人必须要熟悉，那么今天小编为大家介绍各种化工装置的流程图，不仅能帮助大家熟悉各种装置的生产流程还能了解部分生产工艺。

常减压电脱盐装置原则流程从油田送往炼油厂的原油往往含盐(主要是氧化物)带水（溶于油或呈乳化状态），可导致设备的腐蚀，在设备内壁结垢和影响成品油的组成，需在加工前脱除。

电脱盐基本原理：为了脱掉原油中的盐份，要注入一定数量的新鲜水，使原油中的盐充分溶解于水中，形成石油与水的乳化液。

在强弱电场与破乳剂的作用下，破坏了乳化液的保护膜，使水滴由小变大，不断聚合形成较大的水滴，借助于重力与电场的作用沉降下来与油分离，因为盐溶于水，所以脱水的过程也就是脱盐的过程。

CDU装置原则流程CDU装置即常压蒸馏部分常压蒸馏原理：精馏又称分馏，它是在精馏塔内同时进行的液体多次部分汽化和汽体多次部分冷凝的过程。

原油之所以能够利用分馏的方法进行分离，其根本原因在于原油内部的各组分的沸点不同。

在原油加工过程中，把原油加热到360～370℃左右进入常压分馏塔，在汽化段进行部分汽化，其中汽油、煤油、轻柴油、重柴油这些较低沸点的馏分优先汽化成为气体，而蜡油、渣油仍为液体。

+◆◆◆VDU装置原则流程VDU装置即减压蒸馏部分减压蒸馏原理：液体沸腾必要条件是蒸汽压必须等于外界压力。

降低外界压力就等效于降低液体的沸点。

压力愈小，沸点降的愈低。

如果蒸馏过程的压力低于大气压以下进行，这种过程称为减压蒸馏。

+◆◆◆轻烃回收装置原则流程轻烃回收装置是轻烃的回收设备，采用成熟、可靠的工艺技术，将天然气中比甲烷或乙烷更重的组分以液态形式回收。

+◆◆◆RDS装置流程图RDS即渣油加氢装置，渣油加氢技术包含固定床渣油加氢处理、切换床渣油加氢处理、移动床渣油加氢处理、沸腾床渣油加氢处理、沸腾床渣油加氢裂化、悬浮床渣油加氢裂化、渣油加氢一体化技术及相应的组合工艺技术。
