Modular, Skid Mounted Chemical Dosing System

Modular, Skid Mounted Chemical Dosing System

Problem: A treatment plant required a reliable and accurate chemical dosing solution for peracetic acid injection, where precision, safety, and continuous operation were critical. The customer needed a complete, skid-mounted package that would minimize startup time, reduce operational risk, and ensure consistent dosing performance in a demanding environment.

Beyond accuracy, the system also needed built-in protection against common dosing challenges such as pulsation, pressure fluctuations, and potential line blockages while providing operators with clear control and safety features.

Flotation Reagent Dosing System

Flotation Reagent Dosing System

Problem: A mining operation required a highly accurate flotation reagent dosing system to support its flotation process. The application involved five independent dosing points, each critical to process performance and metallurgical results.

The existing setup was experiencing precision and reliability challenges, making it difficult to maintain consistent reagent addition. Furthermore, the system needed to dose multiple reagents including collector, diesel, and frother into separate tanks, increasing complexity and the need for a well-integrated solution.

Reliable Tailings and Concentrate Sampling

Reliable Tailings and Concentrate Sampling

Problem: A mining operation required a reliable tailings and concentrate sampling solution that could be installed directly in the flotation cell area and easily relocated as sampling points or process requirements changed.

Although the application itself was not large in scale, it needed to be:
- Simple to transport and handle
- Quick to connect and disconnect
- Robust enough for repeated use in different locations
- Stable in operation to ensure representative sampling


The challenge was delivering a compact, repeatable system without sacrificing flow stability or reliability.

Rare Earth Mineral Recycling

Rare Earth Mineral Recycling

Problem: A rare earth mineral recycling facility required pulsation control across multiple process lines handling high temperature, chemically aggressive fluids containing entrained solids. The system included both AODD and peristaltic pumps, each generating pressure pulsation that affected process stability and equipment reliability.

In addition to the harsh process conditions, all pressure containing equipment was required to meet CRN requirements, adding an important regulatory constraint.

Pulsation Control in Hi-Temp Coffee Extraction Towers

Pulsation Control in Hi-Temp Coffee Extraction Towers

Problem: The Coffee Manufacturer operates interconnected vertical extraction towers where hot water is circulated at extreme temperatures to produce coffee extract. During operation, the customer observed:

- Rapid water evaporation above 175°C resulting in air pockets inside pipelines
- Slow-reacting temperature instruments, allowing entrained air to persist
- Centrifugal pumps forced to move both air and liquid, leading to:
• Severe water hammer
• Excessive piping vibration
• Damage to plate evaporators and instrumentation
• Partially filled distribution lines on startup, requiring air displacement before flow could stabilize—intensifying water hammer

These issues disrupted extraction quality, compromised equipment life, and increased maintenance cost.

A review of the extraction tower circulation system revealed two primary contributors to the instability:

1. Air Entrapment Due to High-Temperature Evaporation
At 175°C, water rapidly vaporizes. Air and vapor bubbles accumulated in the recirculation lines and plate evaporators. Because the system’s temperature instrumentation responded slowly, air remained trapped far longer than expected—allowing pumps to ingest and compress air repeatedly.

2. Pumping System Not Designed to Handle Vapor Pockets
The 1½” centrifugal pumps recirculating extract between stages were forced to push air through evaporators and distribution lines. This caused major hydraulic consequences:

- Violent pressure spikes (water hammer)
- Resonant vibration in vertical and horizontal piping sections
- Structural stress on evaporators and associated equipment
- This unstable flow environment also threatened extract consistency and overall process quality.

Water Hammer in Wash-Water Header

Water Hammer in Wash-Water Header

Problem: A Midwest sugar processing operation needed a surge suppression solution that could:

- Absorb hydraulic shock from six 3/4" wash-water valves closing rapidly.
- Handle an estimated 300 GPM flow.
- Fit within tight piping constraints.
- Integrate with both old and new centrifugal configurations.
- Stay within the system's #150 flange / 275 PSIG pressure rating.

The team gathered detailed system information including flow estimates, pipe schedule, pressure limits, and isometric drawings. A surge control engineer reviewed the system and collaborated with the company to understand the transient conditions. A Teams call was held to walk through the piping schematic and confirm installation points.
