The global electric desalter & dehydrator market reached $1.789 billion in 2024, with a gross margin of approximately 36.59%. Electric desalter & dehydrator, also known as electrostatic dehydration/desalting equipment, is a key piece of equipment used for deep dehydration and desalting in the oilfield crude oil export processing and refining/chemical feedstock pretreatment stages. Its basic working principle is that under the action of a high-voltage electric field (typically 10–35 kV), through a polarization-coalescing-sedimentation mechanism, the fine water droplets in the crude oil emulsion system attract each other and coalesce into larger droplets. This is then supplemented by demulsifiers, gravity sedimentation, and dilution water injection (in the desalting process) to achieve oil-water separation and inorganic salt migration. In upstream oilfield scenarios, extracted crude oil, after initial separation, typically still contains 10%–30% water and some inorganic salts, making it unsuitable for direct export. It requires deep dehydration through electric dehydration equipment to reduce the water content to below 0.5% to meet pipeline transportation standards. In the pretreatment stage of oil refineries, crude oil must undergo electrostatic desalting (ESD) to remove dissolved or emulsified inorganic salts (such as NaCl, CaCl₂, and MgCl₂) before entering the atmospheric and vacuum distillation tower. Failure to remove these salts can lead to problems such as furnace coking, pipeline corrosion, heat exchanger blockage, and catalyst poisoning, significantly increasing refining energy consumption and maintenance costs. The desalting process typically involves injecting a certain amount of dilution water to dilute the salt concentration, allowing the salts to migrate with the aqueous phase, and then separating the water from the oil phase within a high-voltage electric field. After desalting, the salt content of crude oil can generally be reduced to <5 mg/L, and under optimal operating conditions, it can reach ≤1 mg/L, thus ensuring long-term, low-corrosion, safe, and stable operation of refining units. ESD equipment is widely used in upstream oil and gas extraction, onshore gathering and transportation stations, offshore engineering platforms, refining and chemical plants, and storage and transportation terminals, serving as a key node for oilfield export quality control and refinery energy efficiency management. Typical downstream customers include large domestic and international petrochemical companies such as Sinopec, PetroChina, CNOOC, Yulong Petrochemical, Oriental Shenghong, Rongsheng Petrochemical, Jingbo Holdings Group, as well as international companies such as ADNOC (Abu Dhabi National Oil Company), KPC (Kuwait Oil Company), Qatar Energy, and Petrobras (Brazilian National Oil Company).
Market Trends:
From "Single Function" to "Intelligent Integration": With the popularization of intelligent and information technologies, downstream customers are increasingly demanding intelligent and digital functions from equipment. Remote monitoring of production and manufacturing through equipment upgrades, enabling rapid problem identification and resolution, has become one of the development directions for energy and chemical equipment. Especially in oilfield extraction, refining, and chemical processing, the introduction of intelligent equipment can significantly improve production efficiency, reduce manual intervention, lower equipment failure rates, and enhance safety. Based on current market demand, dehydration and desalination equipment technology will shift from single-function to intelligent integration. Intelligent control systems can automatically adjust operating parameters such as electric field strength, temperature, and pressure, achieving real-time optimization of equipment operation, reducing manual intervention, and improving operational efficiency. Remote monitoring and intelligent sensing systems can monitor equipment status in real time, quickly identify and resolve operational problems, and improve the overall reliability and safety of the equipment. In addition, more and more digital and information technologies are being adopted in energy equipment.
Modularization, Skid-mounted, and Integrated Trends: The state has proposed that refining and chemical equipment will develop towards large-scale operations in the future, and the pace of upgrading and transformation is accelerating. The rise of emerging chemical industries and the trend towards larger-scale equipment are both significantly increasing the demand for energy and chemical equipment. my country is undergoing structural adjustments, achieving integrated refining and chemical production, actively developing high-end refining products, and realizing the technological innovation and transformation and upgrading of petroleum and petrochemical equipment. Simultaneously, due to the continuous improvement of industry technology levels, production processes, and performance requirements, as well as the strengthening of globalization, the scale effect in downstream industries is becoming more pronounced, leading to increasingly higher demands for equipment integration. To effectively control procurement and management costs, downstream enterprises are also inclined to choose large-scale, modular, and specialized equipment. In the future, equipment will develop towards modularization, skid-mounted design, and integration. Many companies have begun to provide customers with integrated multi-functional system solutions (such as crude oil dehydration and desalination, stabilization treatment, and external metering). The National Energy Administration and the petrochemical industry plan propose that future refining capacity will exceed 900 million tons per year. This development has driven the demand for large-scale, integrated dehydration and desalination equipment, especially in the development of complex oil fields and offshore oil fields.
High efficiency, energy conservation, and green development: Under the "dual carbon" background, a series of support policies for energy-saving and emission-reduction technologies and equipment have been promulgated, aiming to promote industrial technological innovation and upgrading. With the continuous strengthening of energy conservation and emission reduction efforts in downstream industries such as petrochemicals, marine engineering, and new energy, high-efficiency energy chemical equipment and new energy equipment will have a larger market. Equipment manufacturers are gradually incorporating green and low-carbon technologies into product design to reduce energy consumption and carbon emissions. For example, the application of variable frequency control and waste heat recovery technologies in dehydration and desalination equipment will significantly improve energy efficiency and reduce the carbon footprint.
The replacement cycle for electrostatic precipitators (ESPs) is approximately 10-15 years. With the implementation of integrated refining and chemical policies and the introduction of equipment replacement policies, this cycle will be further shortened. On the one hand, the proportion of high-salt and high-water-content crude oil in global new crude oil production is increasing, leading to increasingly diversified crude oil supply and increasingly deteriorating crude oil quality. This necessitates further enhancements in the adaptability of ESPs to inferior crude oil and their resistance to fluctuations in feedstock properties.
