Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Driven by the "dual carbon" strategy and the Implementation Plan for High-Quality Development of Energy-Saving Equipment (2026–2028), technological innovation is becoming a key driver for the green and low-carbon transformation of the petroleum and petrochemical industry. Focusing on complex application scenarios such as oil and gas exploration and development, refining and chemical processing, oil and gas gathering and transportation, and new energy integration, the is accelerating the construction of a new generation of core equipment systems that are self-controllable, highly efficient and energy-saving, and intelligently coordinated, pushing traditional high-energy-consuming industries toward high-quality development. In the field of general energy-consuming equipment, core devices such as motors, fans, pumps, and compressors are undergoing key technological upgrades. By breaking through core components like low-cost permanent magnet materials, high-magnetic-induction low-loss silicon steel, and magnetic suspension bearings, the industry is accelerating the development of ultra-premium-efficiency wide-range permanent magnet motors, direct-drive motors, and oil-free permanent magnet direct-drive pumps. Particularly in applications such as oilfield water injection, refining circulation, high-temperature transport, and continuous variable-load conditions, integrating variable frequency speed control, low-loss fluid transport, and waste heat recovery technologies can effectively solve the high energy consumption problem caused by the "large horse pulling a small cart" phenomenon in traditional systems, achieving efficient system matching and operation. At the same time, power transmission and distribution equipment is also moving toward intelligence and high efficiency. To meet the demands of refining power grids, new energy grid integration, and oilfield power supply, large-capacity amorphous alloy transformers, intelligent on-load tap-changing transformers, and three-dimensional wound-core transformers are being gradually promoted, improving new energy consumption capacity and reducing grid losses. In the field of industrial thermal energy equipment, high-power high-temperature industrial heat pumps, steam heat pumps, and condensing waste heat recovery systems are being rapidly applied in areas such as heavy oil thermal recovery, refining heating, and chemical separation. By recovering flue gas, circulating water, and waste heat resources to replace part of fossil energy, these systems achieve cascade utilization of thermal energy and system energy savings. Furthermore, with the development of the green hydrogen refining and CCUS industry, low-energy water electrolysis hydrogen production equipment has also become a key breakthrough direction. By optimizing electrolyzer structural design and core material performance, alkaline, PEM, and AEM electrolyzers are being pushed toward higher efficiency and wider load range. In the future, the development of energy-saving equipment in the petroleum and petrochemical industry will not only focus on single-device energy savings but will further evolve toward system coupling optimization, digital intelligent control, and full-process energy efficiency management. Leveraging digital twins, edge computing, and intelligent optimization algorithms, real-time monitoring of equipment operating status and precise energy consumption management will be achieved, pushing the industry from "single-point energy saving" to a new stage of "full-system high-efficiency synergy." Technological innovation is the primary driving force for the iterative upgrading of energy-saving equipment. Based on the energy consumption scenarios of the entire petroleum and petrochemical industry chain, it is essential to closely follow the deployment of the Plan, focus on key areas with precision, and accelerate the formation of a self-controllable, highly efficient, low-carbon, and highly adaptable equipment technology system.

Combining the characteristics of variable load, continuous operation, and complex working conditions in oil and gas exploration and development, water and gas injection, oil and gas gathering and transportation, and refining and chemical processing, strengthen the integrated application of energy-saving technologies such as variable frequency speed control, heat recovery, and low-loss fluid transport, promoting efficient system matching and operation, and solving the low-efficiency problem of "large horse pulling a small cart." Second, innovation in power transmission and distribution equipment. To meet the demands of oilfield power grids, refining power grids, and new energy grid integration, develop three-dimensional wound-core transformers, large-capacity high-efficiency amorphous alloy transformers, and intelligent on-load tap-changing transformers, improving wind-solar-storage compatibility and green electricity consumption capacity. Promote energy-saving diagnosis and reactive power compensation transformation of in-service transformers, reduce grid losses, and support the clean energy transformation of the entire industry chain. Third, innovation in industrial thermal energy equipment. For scenarios such as heavy oil thermal recovery, oil and gas gathering and transportation, refining heating, and chemical separation, develop high-power high-temperature industrial heat pumps, industrial steam heat pumps, and condensing heat recovery equipment, recovering waste heat from flue gas, wastewater, and circulating water to replace fossil energy. Promote IGBT induction electric furnaces and heat pump drying technology, raising the low-load efficiency of heating furnaces to over 88%, achieving cascade efficient utilization of thermal energy. Fourth, innovation in green electricity hydrogen production equipment. Closely following the direction of green hydrogen refining and CCUS, break through core technologies such as low-iridium/non-precious metal catalysts, high-performance diaphragms, and long-life electrodes, optimize the multi-physics field collaborative design of electrolyzers, and improve the efficiency and wide-load adaptability of alkaline, PEM, and AEM electrolyzers, ensuring that by 2028, mass-produced water electrolysis hydrogen production equipment achieves a DC power consumption of less than 4.2 kWh/Nm³ under rated conditions. Fifth, innovation in system coupling and matching. Establish a wide-range high-efficiency evaluation system for petroleum and petrochemical equipment under variable working conditions, promoting precise matching of equipment, load, working conditions, and energy consumption systems. Focus on creating benchmarks such as high-efficiency compressed air stations, centralized pump stations, intelligent water injection systems, electric drive fracturing clusters, and high-efficiency refining heating systems, achieving a leap from single-device energy saving to system optimization and full-process efficiency improvement.
