Prochem Dense Phase Pressure Conveying Systems

This method uses compressed air to convey materials at low velocities, minimizing product degradation. It operates in a batch-like manner, filling an ASME vessel, pressurizing it, conveying the material, then repeating the process. Powder can stay in the convey line during vessel refills. Velocities range from 200 to 1000 feet/minute, regulated by monitoring convey pressures, with boosters sometimes needed for longer distances.

Key Features:

• Gentle conveying
• Mild steel and stainless steel construction
• Control system with sensors for dense phase convey rate control
• Maintains air-to-product ratio to prevent plugging
• Uses compressed air as conveying medium
• Operates in batch sequence
• Optional: continuous dense phase operation
