Singapore Seletar Desulfurization Hydrated Lime Powder Automatic Dosing Complete Project represents a milestone in the field of bulk material handling and environmental engineering. This project, executed by Shandong Haide Powder Engineering Co., Ltd., integrates advanced pneumatic conveying technology with automated dosing systems to deliver efficient and reliable desulfurization solutions for thermal power plants and industrial boilers. The core equipment and processes are specifically designed to handle hydrated lime powder, a key reagent in flue gas desulfurization, ensuring precise dosing and minimal material waste.
At the heart of this project lies the desulfurization hydrated lime pneumatic conveying system, which transports fine lime powder from storage silos to injection points using compressed air. This method eliminates mechanical wear and dust leakage, providing a clean and low-maintenance operation. The automatic dosing pneumatic conveying system further enhances process control by integrating sensors, PLC controllers, and variable frequency drives to adjust the feed rate in real time based on flue gas conditions. Both systems are tailored for the humid tropical climate of Singapore, ensuring stable performance under high ambient temperatures and humidity. The complete project scope includes silo design, pipeline layout, control panel integration, and commissioning services.
Hydrated lime powder, with its fine particle size and hygroscopic nature, requires specialized conveying solutions. The pneumatic conveying system employed in this project utilizes a dense phase principle, where the material is pushed through pipes at low velocity, minimizing abrasion and energy consumption. Air compressors, air dryers, and rotary valves work in tandem to create a consistent flow. The system is fully enclosed, preventing any fugitive dust and protecting the powder from moisture ingress. This design is critical for maintaining the reactivity of the lime, which directly impacts the desulfurization efficiency. The Singapore pneumatic conveying system has been optimized for the specific distance and elevation of the Seletar site, achieving throughput rates of up to 10 tons per hour with negligible degradation.
Accuracy in reagent dosing is essential for meeting strict emission standards. The automatic dosing pneumatic conveying system features a gravimetric feeder that measures the mass flow of lime powder and adjusts the conveying air pressure accordingly. A central control room equipped with a distributed control system (DCS) monitors all parameters, including silo level, line pressure, and injection rate. Operators can set predefined recipes or switch to manual override for maintenance. The system also includes a redundant emergency shutdown mechanism to ensure safety. By automating the dosing process, the plant reduces manual labor and improves overall process consistency, leading to lower operational costs and higher compliance with environmental regulations.
The Seletar project is located in a region with stringent air quality requirements. The desulfurization hydrated lime pneumatic conveying system was engineered to handle the high humidity and occasional rainfall without compromising material flow. Special anti-blockage nozzles and heated air dryers were incorporated to prevent lime from caking. The system interfaces seamlessly with existing flue gas desulfurization units, providing a turnkey solution from material reception to injection. This project demonstrates the capability of Shandong Haide Powder Engineering Co., Ltd. to deliver complex pneumatic conveying systems overseas, meeting international standards such as ISO and ASME. The successful installation and operation in Singapore serve as a reference for similar projects in Southeast Asia and other regions.
