This case study presents a successful implementation of a petroleum coke powder hybrid pneumatic conveying system designed for a major petrochemical plant located in Fuzhou, Fujian Province. The project aimed to efficiently transport petroleum coke powder—a byproduct of the refining process—from storage to downstream processing units while minimizing dust emissions, energy consumption, and maintenance costs. The solution provided by Shandong Headpowder Engineering Co., Ltd. (abbreviated as headpowder) integrates advanced hybrid pneumatic conveying technology with customized material handling strategies tailored to the unique characteristics of petroleum coke powder and other petrochemical byproducts. This article details the core equipment, system design, operational benefits, and the role of Shandong Headpowder Engineering Co., Ltd. in delivering a reliable, cost-effective conveying solution.
The primary products involved in this project include petroleum coke powder hybrid conveying systems, petrochemical byproduct conveying systems, and comprehensive hybrid pneumatic conveying engineering services. The petroleum coke powder hybrid conveying system combines dense-phase and dilute-phase conveying principles to handle both fine and coarse particles with minimal degradation. This hybrid approach ensures stable flow even when the material exhibits high moisture content or irregular particle size distribution. Additionally, the petrochemical byproduct conveying system is designed to handle materials such as spent catalyst, coke fines, and other residues generated during refining operations. These systems are engineered to operate under high temperature, abrasive conditions, and variable feed rates, all while maintaining a sealed environment to prevent fugitive dust. Shandong Headpowder Engineering Co., Ltd. provides end-to-end hybrid pneumatic conveying engineering, including system design, component selection, installation supervision, and commissioning, ensuring that each project meets the specific requirements of the client's site.
The hybrid pneumatic conveying system deployed in Fuzhou features a patented dual-mode conveying mechanism that automatically switches between dense-phase and dilute-phase flow based on real-time sensor data of material density, pressure drop, and air velocity. This intelligent adaptation reduces air consumption by up to 30% compared to conventional dilute-phase systems, while also lowering pipe wear caused by particle impact. The system incorporates a feed hopper with a rotary valve specially designed for petroleum coke powder, which prevents bridging and ensures consistent material discharge. Downstream, a series of cyclones and bag filters recover the conveyed material with over 99.5% efficiency, and the captured fines are returned to the main stream without additional handling. The control system, built on a PLC platform with remote monitoring capabilities, allows operators to adjust conveying parameters from a central control room or via a mobile interface. This level of automation is critical for petrochemical plants that require continuous, uninterrupted operation. The hybrid conveying technology is also scalable: the same design principles have been applied to multiple other hybrid pneumatic conveying engineering projects for petrochemical, cement, and power generation industries.
The client, a large petrochemical enterprise in Fuzhou, Fujian, faced several challenges in handling petroleum coke powder generated from delayed coking units. The existing mechanical conveying system suffered from frequent blockages, excessive dust leakage, and high maintenance costs. The plant required a new solution that could handle a throughput of 15 tons per hour with a conveying distance of 120 meters, including vertical lifts of 20 meters. Furthermore, the system needed to accommodate the seasonal variation in moisture content of the petroleum coke powder, which ranged from 5% to 15%. After evaluating multiple vendors, the client selected Shandong Headpowder Engineering Co., Ltd. due to the company's proven track record in hybrid pneumatic conveying systems for similar petrochemical applications. The contract scope included the supply of key components, engineering design, site supervision, and performance guarantees.

The design phase began with a thorough analysis of the petroleum coke powder's physical properties, including particle size distribution (< 200 mesh), bulk density, abrasiveness, and moisture adsorption behavior. Based on these data, headpowder's engineers selected a combination of a positive displacement blower and a high-pressure air supply network to achieve the required conveying velocities. The pipeline was constructed from wear-resistant steel with an internal diameter of 150 mm, incorporating expansion joints and wear backs at bends. A total of three injection points were installed along the line to allow for staged material entry, reducing the risk of plugging. The hybrid conveying mode was configured with a dense-phase "slug flow" pattern for horizontal sections and a dilute-phase "suspension flow" for vertical risers, automatically switched by the PLC. Commissioning tests demonstrated that the system could handle the full range of moisture content without any blockage, and the measured conveying efficiency exceeded 98%. The project was completed within the scheduled 4-month timeline, and the client reported a 40% reduction in energy consumption compared to the previous mechanical system, along with a 90% decrease in dust emissions.
Hybrid pneumatic conveying is particularly well-suited for petrochemical byproducts such as petroleum coke powder because it offers a balance between low air consumption and high material integrity. Unlike purely dense-phase systems that may struggle with cohesive powders, or purely dilute-phase systems that waste energy, the hybrid method adapts to the material's characteristics in real time. This results in lower pipe wear, reduced degradation of the product, and simpler maintenance. Additionally, the closed-loop design prevents any escape of fine particles, which is critical in petrochemical environments where dust can pose explosion hazards. The system also supports easy integration with existing plant infrastructure, including silos, baghouses, and weigh feeders. Shandong Headpowder Engineering Co., Ltd. has applied this technology in numerous projects across China, including refineries in Shandong, Jiangsu, and Guangdong provinces.
