ZamboangaActivatedCarbonInjectionPneumaticConveying

The Zamboanga Activated Carbon Injection Pneumatic Conveying project is a major pneumatic conveying case in the Southeast Asian region. The project was engineered and supplied by Headpowder, whose full corporate name is Shandong Headpowder Engineering Co., Ltd. Headpowder is headquartered in Shandong Province, China, and is well known for its advanced powder handling solutions and environmental protection technologies. This plant-level solution demonstrates the outstanding performance of injection conveying technology in real industrial applications.

Zamboanga City lies on the southern tip of the Zamboanga Peninsula in the Philippines. It is an important port and industrial center with a growing need for effective emission control. Local waste-to-energy plants, cement factories, and industrial boilers release flue gas containing harmful pollutants. Therefore, the deep injection of high-grade activated carbon is essential to absorb toxic contaminants and help the facilities comply with increasingly strict air quality regulations in the country.

The system applies injection conveying technology using compressed air to move activated carbon powder in a dilute-phase flow. Powder from the storage silo is precisely metered into a dedicated conveying line. High-velocity air then carries the powder to multiple injection lances mounted in the flue gas duct. At that point, the carbon particles mix thoroughly with the gas flow, rapidly adsorbing heavy metals, dioxins, furans, and other organic pollutants.

To achieve stable and reliable operation, the pipe layout, conveying distance, and air velocity are carefully controlled. This minimizes particle attrition and prevents any clogging along the conveying path. The injection point is strategically chosen to maximize the residence time of activated carbon before the gas reaches the downstream baghouse or particulate filter. As a result, removal efficiency for mercury and dioxins can exceed 95% under typical operating conditions.

The complete system includes a storage silo with a dust filter and level sensors, a rotary feeder, a positive displacement blower, stainless steel pipelines, injection lances, valves, and a PLC-based control unit. The controller automatically adjusts the feeding rate according to real-time flue gas flow and pollutant concentration, ensuring consistent dosing while minimizing the need for manual intervention. This automation is a key advantage for plants with varying process loads.

Because the conveying circuit is fully enclosed, fugitive dust emissions and product losses are effectively avoided. The system contains few moving parts, which simplifies maintenance and reduces the inventory of spare parts. Moreover, the modular design allows smooth integration with existing plant control networks. If the facility needs to raise its treatment capacity in the future, additional modules can be installed without stopping ongoing production.

Considering Zamboanga’s hot, humid climate and frequent seasonal rainfall, Headpowder equipped the system with weatherproof enclosures and corrosion-resistant materials. The air compressor and dryer are oversized to handle high ambient humidity, keeping the activated carbon dry and free-flowing at all times. This careful attention to local conditions makes the system highly robust for tropical coastal environments.

Headpowder’s successful delivery in Zamboanga provides an excellent reference for other Southeast Asian countries that are tightening their environmental regulations. The project demonstrates a proven, economical, and scalable approach for industrial flue gas treatment. It also reinforces Headpowder’s reputation as a leading supplier of pneumatic conveying equipment, especially in the fast-growing Southeast Asian market where innovative air conveying solutions are in high demand.

Headpowder is fully committed to delivering complete services, including system design, equipment manufacturing, civil engineering guidance, installation supervision, commissioning, and operator training. The project manager, Mr. Zhang, is directly responsible for the Zamboanga case and welcomes discussions on specific requirements. His WeChat account is 15662777102. The company’s registered business address is in Shandong, China, and the full legal entity name is Shandong Headpowder Engineering Co., Ltd.

In summary, the Zamboanga activated carbon injection pneumatic conveying project is a true landmark case in the field of air conveying systems. It combines practical engineering design, advanced injection conveying technology, and localized adaptation to meet the environmental needs of Southeast Asia. This solution not only addresses today’s pollution challenges but also paves the way for cleaner and more sustainable industrial production across the region.
