In modern chemical and petrochemical processing, the efficient and safe transfer of catalyst particles is a critical operation that directly impacts productivity, product quality, and operational safety. Catalyst particles, whether in the form of powders, granules, pellets, or microspheres, require specialized handling due to their abrasive nature, friability, sensitivity to moisture, and potential for dust generation. Pneumatic conveying has emerged as the preferred method for moving these materials within a plant, offering a closed, dust-free, and flexible transport solution. Our company specializes in designing and manufacturing tailored pneumatic conveying systems that are specifically engineered to handle the unique characteristics of catalyst particles, ensuring gentle handling, minimal degradation, and reliable continuous operation.

The core of our service lies in providing a comprehensive solution that encompasses system design, equipment selection, installation supervision, and after-sales support. We understand that every catalyst handling scenario is unique, influenced by factors such as particle size distribution, bulk density, moisture content, temperature sensitivity, and the required conveying distance and capacity. Therefore, we offer both dilute phase and dense phase pneumatic conveying systems, each meticulously optimized to match your specific material properties and process requirements. Our engineering team conducts thorough material testing and flow analysis to determine the optimal conveying velocity, air-to-material ratio, and pipeline configuration, thereby preventing issues such as particle breakage, pipeline erosion, and system blockage.

For fragile or abrasive catalyst particles, we strongly recommend our dense phase conveying technology. This system operates at low velocity and high pressure, gently pushing the material through the pipeline in a plug-like flow. This significantly reduces particle-to-particle and particle-to-wall collisions, preserving the structural integrity and activity of the catalyst. In contrast, for free-flowing and less fragile materials, our dilute phase conveying system offers high capacity at lower capital cost. It suspends particles in a high-velocity air stream, making it suitable for shorter distances and simpler layouts. Regardless of the mode, our systems are equipped with advanced control valves, sensors, and automation software to ensure precise feeding, stable pressure, and real-time monitoring of the entire conveying process.

The equipment we provide covers the entire conveying loop, starting from a receiving hopper or silo, through a rotary airlock valve, screw feeder, or pressure vessel, into the conveying pipeline, and finally to a destination separator such as a cyclone, bag filter, or silo vent filter. Each component is constructed from high-quality wear-resistant materials, such as hardened steel, ceramic-lined pipes, or special alloys, to withstand the erosive nature of catalyst particles and prolong service life. We also pay special attention to sealing performance and dust containment, ensuring that the system meets strict environmental and safety regulations. Explosion protection measures, such as rupture discs, explosion vents, and inert gas blanketing, can be integrated into the design for handling flammable or reactive catalysts.

Our customized approach means that we do not offer off-the-shelf solutions. Instead, we follow a rigorous engineering process that begins with a detailed consultation and on-site survey. Our engineers evaluate your existing process flow, available space, power supply, and control system compatibility. They also analyze the physical and chemical properties of the catalyst particles, including particle size distribution, angle of repose, cohesion, and abrasiveness. Based on this data, we generate a system design that minimizes energy consumption, reduces maintenance downtime, and ensures gentle material handling. We use computational fluid dynamics (CFD) simulations to model the two-phase flow inside the pipeline, allowing us to predict pressure drops, velocity profiles, and potential wear points before installation.

Beyond the core conveyor, we also offer ancillary systems that enhance the overall efficiency of catalyst transfer. These include aspiration systems for dust collection, dehumidifiers or dryers for moisture control, metal detectors for contamination prevention, and weighing systems for batch accuracy. For processes that require nitrogen or other inert gases, we can design closed-loop conveying systems that recover and recycle the conveying gas, reducing operational costs and environmental emissions. Our control systems feature intuitive human-machine interfaces (HMIs) that allow operators to easily set parameters, monitor trends, and receive alarms. Integration with your existing distributed control system (DCS) or programmable logic controller (PLC) is fully supported, ensuring seamless operation across the entire plant.

The importance of reliable catalyst handling extends beyond simple material transfer. In processes such as fluid catalytic cracking (FCC), methanol-to-olefins, and ammonia synthesis, the catalyst is a high-value asset that directly determines reaction kinetics and yield. Any degradation or loss of catalyst during conveying can result in significant economic loss and process upset. Our gentle conveying solutions help minimize fines generation and catalyst attrition, thereby preserving the active surface area and extending the catalyst life. Additionally, our systems are designed for easy cleanout and maintenance. We offer features such as quick-disconnect couplings, sight glasses, and access doors to facilitate routine inspections and removal of any residual material.

We have implemented successful projects across various industries, including refineries, petrochemical plants, natural gas processing, and fine chemical manufacturing. Our clients range from small-scale pilot plants to world-scale production facilities. In each project, we have demonstrated the ability to handle catalyst particles of different sizes and shapes—from fine powders of a few microns to cylindrical extrudates of several millimeters. Our experience includes conveying temperatures ranging from ambient to over 300 degrees Celsius, and conveying distances extending beyond 500 meters. Regardless of the requirements, our engineering expertise and manufacturing capabilities enable us to deliver a system that performs reliably and efficiently.

One of the key differentiators of our service is our commitment to post-installation support. We provide comprehensive commissioning assistance, operator training, and detailed operating manuals. Our team remains available for troubleshooting, spare parts supply, and system upgrades even after the warranty period. We believe that a successful catalyst conveying system is not just a piece of equipment, but a long-term partnership that ensures your production line keeps running at optimum performance. Our maintenance programs can include scheduled inspections, wear part replacements, and performance evaluations to identify potential issues before they cause downtime.
