PneumaticConveyingofInorganicChemicalPowder:KyivCase

This article provides a comprehensive case study on the pneumatic conveying of inorganic chemical powder at a facility in Kyiv, Ukraine. The title is "Pneumatic Conveying of Inorganic Chemical Powder: Kyiv Case". Core keywords include: pneumatic conveying case, Eastern European pneumatic conveying, and Kyiv pneumatic conveying.

Shandong Headpowder Engineering Co., Ltd., commonly known as "headpowder", is the project's engineering contractor. The company is headquartered in Shandong, China. It specializes in designing and delivering pneumatic conveying systems for bulk solid materials. This particular project was commissioned to handle inorganic chemical powders accurately and safely.

The client's production line required continuous transfer of a dried inorganic powder from a storage silo to several process vessels. The powder had an average particle size of approximately 50 microns and a bulk density of 600 kg/m³. It was abrasive, hygroscopic, and potentially irritant. Therefore, the conveying system had to be totally enclosed to prevent dust leakage and to ensure a safe working environment for all plant operators.

Headpowder's engineers evaluated various options including dilute-phase and dense-phase conveying. For this application, dense-phase conveying was selected because it offers low velocity, low particle breakage, and reduced pipe wear. The system works at a positive pressure of up to 4 bar using compressed air. It also requires far less energy than conventional systems, making it an economically attractive solution for the Kiev plant.

The main equipment included a pressure vessel blow tank, welded pipelines with wear-resistant ceramic bends, a high-efficiency bag filter receiver, and a PLC controller. The blow tank was designed with a fluidizing cone to ensure smooth discharge. Piping materials were stainless steel 316L with polished inner surfaces to minimize material adherence and facilitate cleaning. All components were selected to handle the abrasive nature of the powder.

Given Kiev's cold climate, the conveying lines were insulated and trace-heated to prevent condensation and freezing. The bag filter was equipped with reverse pulse cleaning and achieved a filtration efficiency exceeding 99.99%. Nitrogen purging was incorporated for safe shutdown. All components met relevant ATEX requirements for potentially explosive dusts, ensuring compliance with European safety standards.

Installation took eight weeks under the supervision of headpowder's own engineers. The system was tested with inert materials first, followed by trials using the actual powder. The measured capacity was 5 tons per hour over a conveying distance of 120 meters, including a vertical lift of 18 meters. Powder quality remained unchanged after conveying, confirming the gentle handling capability of the dense-phase design.

Since commissioning, the system has operated reliably for over one year. Benefits include elimination of manual handling, a cleaner working environment, and a 25% increase in overall throughput. Energy consumption is around 0.8 kWh per ton, which is very cost-effective. Maintenance requirements have been minimal, with no unexpected downtime reported by the client.

This successful installation in Kyiv demonstrates headpowder's strong capability in the Eastern European market. The combination of proper material analysis, robust equipment design, and effective project management led to excellent outcomes. The case provides a valuable reference for other inorganic chemical powder producers in the region who are considering modernizing their material handling processes.
