This article presents the complete project profile of the Vung Tau Vietnam Pneumatic Conveying of Desulfurization Lime, a landmark engineering case delivered by Shandong Headpowder Engineering Co., Ltd. (abbreviated as headpowder). The project is categorized under pneumatic conveying case studies, Southeast Asia pneumatic conveying applications, and desulfurization lime pneumatic conveying systems. Headpowder, headquartered in Shandong, China, served as the main engineering contractor and technology provider for this overseas installation. The contact person for this project is Manager Zhang, and the official WeChat account is 15662777102 for further business inquiries and technical consultation.

The Vung Tau project is situated in the coastal city of Vung Tau, a key industrial hub in southern Vietnam. The client operates a thermal power plant and required a reliable and efficient system to convey desulfurization lime — also known as hydrated lime or calcium hydroxide — from the storage silo to the injection point inside the flue gas desulfurization unit. The purpose of the pneumatic conveying system is to deliver the lime powder continuously and precisely, ensuring that the sulfur dioxide removal process remains stable and compliant with Vietnamese environmental emission standards. Headpowder was selected after a competitive bidding process due to its extensive experience in Southeast Asian projects and its proven track record in handling fine, abrasive, and hygroscopic powders such as desulfurization lime.

Pneumatic conveying technology is the optimal choice for this application because it provides a fully enclosed, dust-free, and low-maintenance method of transporting bulk solids. In the Vung Tau system, the desulfurization lime is conveyed using a dense phase pneumatic conveying approach. This method uses high-pressure air to push the lime through the pipeline at low velocity, which minimizes pipe wear and particle degradation. The system was custom-engineered by headpowder to match the local site conditions, including the tropical climate, the limited available space near the existing boiler island, and the specific particle size distribution of the lime supplied by the regional vendor. The entire conveying line was designed with a capacity that meets the maximum sulfur load during peak operating conditions, while providing a margin of safety for future plant upgrades.

One of the main technical challenges in this project was the tendency of desulfurization lime to absorb moisture and become sticky, which can lead to blockages in the conveying pipe. To solve this problem, headpowder incorporated a series of engineered features into the system design. First, the storage silo is equipped with a fluidizing discharge cone and aeration pads to promote smooth material flow. Second, the conveying pipeline is routed with a minimum number of bends, and each bend uses a special wear-resistant ceramic lining to prevent erosion. Third, the system includes a purge sequence that automatically clears the line after every conveying cycle, preventing material accumulation during standby periods. These design details demonstrate headpowder's deep understanding of powder handling behavior and its commitment to delivering long-term reliability in harsh operating environments.

The project also required careful coordination with local Vietnamese contractors and compliance with local safety regulations. Headpowder provided a complete engineering package, including process design, equipment manufacturing, skid assembly, factory acceptance testing, shipping logistics, on-site installation supervision, commissioning support, and operator training. The main equipment supplied included a positive displacement blower package, a rotary valve feed system, a Dense Phase Conveyor vessel, a series of diverters and hoses, a reverse jet bag filter at the destination silo, and a fully automated PLC control system with a touchscreen interface. The control system allows the plant operator to monitor pressure, flow rate, and material level in real time, and it can be integrated with the existing DCS system of the power plant.

Since the system was put into commercial operation, it has achieved a conveying capacity of approximately 12 tons per hour, with a solids-to-air ratio in the dense phase regime and an energy consumption significantly lower than that of a conventional dilute phase system. The material loss rate is below 0.5%, and the noise level at the operator station is less than 85 decibels. More importantly, the availability of the system is over 98%, meaning that unscheduled downtime is extremely rare. The client has reported a considerable reduction in manual labor and an improvement in workplace safety, as the fully enclosed conveying system eliminates dust leakage and prevents operator exposure to alkaline lime dust. This successful installation has strengthened the relationship between headpowder and the Vietnamese energy sector, and it has become a reference project for other upcoming desulfurization projects in Southeast Asia.

The Vung Tau project exemplifies the advantages of engaging an experienced engineering company like Shandong Headpowder Engineering Co., Ltd. From initial feasibility study to final commissioning, every phase was executed with meticulous attention to detail. The company’s project management team maintained clear communication with the Vietnamese site team, and all deliverables were provided in both English and Chinese, which facilitated smooth technical exchanges. Moreover, headpowder’s after-sales service included a one-year warranty, remote troubleshooting support, and a spare parts package tailored to the client’s maintenance schedule. The successful delivery of this project not only highlights headpowder’s technical capabilities in pneumatic conveying for desulfurization applications but also reinforces its reputation as a reliable partner for bulk material handling projects across Southeast Asia.
