A major petrochemical enterprise located in Lanzhou, Gansu Province, recently implemented a customized mixed pneumatic conveying system to handle its catalyst transport requirements. The project, delivered by Shandong Headpowder Engineering Co., Ltd. (brand abbreviation: headpowder), focuses on the efficient and reliable transfer of catalyst materials within the refinery. The system integrates both positive pressure and negative pressure conveying mechanisms, forming a comprehensive positive and negative pressure mixed system that ensures stable, dust-free, and high-capacity material handling. This case study highlights the technical advantages of the catalyst mixed conveying solution and its suitability for demanding petrochemical environments.
The core of this project is a positive and negative pressure mixed system designed specifically for catalyst mixed conveying and petrochemical raw material conveying. The system utilizes a combination of dense-phase positive pressure conveying for long-distance, high-capacity transport, and vacuum-based negative pressure conveying for feeding and unloading from multiple points. This hybrid approach minimizes material degradation, reduces energy consumption, and prevents catalyst dust emission. The system is fully automated, with PLC-controlled valves, pressure sensors, and flow regulators to maintain optimal conveying parameters. The catalyst mixed conveying process ensures that the catalyst particles maintain their integrity, which is critical for maintaining catalytic activity in downstream reactors.
The mixed pneumatic conveying system delivered by headpowder incorporates several advanced features. First, the positive and negative pressure mixed system allows for seamless switching between conveying modes, adapting to different material characteristics and plant layout constraints. Second, the system is designed for petrochemical raw material conveying, handling not only catalysts but also other fine powders and granular materials commonly used in refineries. Third, the equipment is constructed with wear-resistant materials and explosion-proof components, meeting the highest safety standards for hazardous environments. The system's closed-loop design eliminates material loss and contamination, ensuring consistent product quality. The catalyst mixed conveying technology has been proven to increase throughput by up to 30% compared to traditional mechanical conveying methods.
In the Lanzhou petrochemical plant, the mixed pneumatic conveying system has significantly improved operational efficiency. The petrochemical raw material conveying process now runs continuously with minimal downtime, thanks to the system's self-cleaning filters and automatic purge cycles. The positive and negative pressure mixed system enables the plant to convey catalysts from storage silos to reactor feed hoppers over distances exceeding 200 meters, with elevation changes of up to 40 meters. The system's low air-to-material ratio reduces nitrogen consumption, lowering operational costs. Furthermore, the enclosed conveying path prevents catalyst dust from escaping, improving workplace safety and environmental compliance. The project demonstrates how catalyst mixed conveying technology can be adapted to existing plant layouts without major structural modifications.
