Simplicity Is Our Technology™

Sorbent Dynamics Dry Sorbent Injection (DSI) systems are air pollution control technologies used to reduce the emissions of acid gases, mainly HCl and SO2, as well as other pollutants from industrial combustion processes.

Dry sorbent injection is an effective and relatively cost-efficient method for controlling acid gas emissions compared to other technologies, like wet and semi-dry scrubbers and circulating fluid bed scrubbers.

Sorbent Dynamics designs and engineers equipment used in Dry Sorbent Injection systems. Our systems are characterized by dependability and simplicity of design.

Simplicity truly is our technology.

Make Your Next Project Quick and Easy

Before Plan, Understand The Process

**Here's how DSI works:

Injection of Sorbent Material: Dry sorbent powder, such as hydrated lime (calcium hydroxide) or finely milled sodium bicarbonate, are injected into the flue gas stream.

Chemical Reaction: When the sorbent material comes into contact with the acid gases, a chemical reaction occurs, reacting with the sorbent to form a less harmful compound.

Particle Collection: The reaction products, which are in solid form, are then collected along with the sorbent particles in particulate control devices such as baghouses or electrostatic precipitators. This removes the pollutants from the flue gas.

Cleaned Flue Gas Emission: The treated flue gas, now with reduced levels of acid gases and other pollutants, is released into the atmosphere through a stack.

6 Simple Steps to a Successful DSI System:

Step 1: Specify Your Process

If necessary, we will work with you to define the pollution abatement process and determine which sorbent solution is best for your process.

Step 2: Analyze Your Problem

The next step is to help you determine which system or component is best suited to achieving your process solution.

Step 3: Build Your Equipment

We will then design and build your system according to your demanding quality requirements and specifications.

Step 4: Integrate Into Your Process

We will assist you with the integration process to ensure that your plant is working in the most effective and synergistic way possible.

Step 5: Assist With Installation

Our expert installation and erection supervision will help you to reduce on-site cost by helping you find the most effective methods of installation.

Step 6: Comissioning and Training

Our commissioning engineers will assist you with initial operation and training on operation and maintenance functions.
