Developed and marketed by Solvay America, T-2000 is a dry sorbent designed for use in baghouses to effectively capture and remove harmful pollutants from industrial emissions.
What is a dry sorbent?
Dry sorbents are solid materials that chemically bind to pollutants in the gas phase, effectively removing them from the air stream. These sorbents typically operate at ambient temperatures and can be used in various industrial applications, including:
T-2000: Key Features and Advantages
T-2000 is a highly effective dry sorbent with several key advantages:
How T-2000 Works in Baghouses
Baghouse systems utilize filter bags to capture particulate matter from exhaust gases. When T-2000 is used in conjunction with baghouses, the sorbent is injected into the gas stream upstream of the filter bags. The sorbent particles come into contact with the pollutants and bind to them, preventing them from reaching the filter bags. The sorbent-pollutant mixture is then collected in the hopper below the baghouse and disposed of or recycled.
Conclusion
T-2000 is a reliable and efficient dry sorbent, providing a powerful tool for controlling air pollution. Its high capacity, reactivity, and ease of use make it a valuable asset for industries seeking to minimize their environmental impact. By effectively capturing and removing harmful pollutants, T-2000 contributes to cleaner air and a healthier environment.

Scenario: A power plant is using T-2000 to remove sulfur dioxide (SO2) from its flue gas. The plant produces 100,000 cubic meters of flue gas per hour, with an SO2 concentration of 500 ppm (parts per million). T-2000 can capture 90% of the SO2.
Task:
**1. Total mass of SO2 emitted per hour:**
* **SO2 concentration in flue gas:** 500 ppm = 500 / 1,000,000 = 0.0005 * **Volume of SO2 in flue gas:** 100,000 m3/h * 0.0005 = 50 m3/h * **Mass of SO2:** 50 m3/h * 2.9 kg/m3 = 145 kg/h
**2. Mass of SO2 removed per hour:**
* **SO2 removal efficiency:** 90% * **Mass of SO2 removed:** 145 kg/h * 0.90 = 130.5 kg/h
**3. Mass of SO2 emitted per hour after T-2000 implementation:**
* **Mass of SO2 emitted after removal:** 145 kg/h - 130.5 kg/h = 14.5 kg/h
Chapter 1: Techniques
T-2000's application relies on the established technique of dry sorbent injection into baghouses. This involves injecting the finely powdered T-2000 sorbent into the gas stream upstream of the filter bags. Several factors influence the effectiveness of this technique:
Injection Point: The optimal injection point is crucial for maximizing contact between the sorbent and pollutants. This often requires careful consideration of gas flow dynamics and turbulence within the ductwork. Poor placement can lead to uneven distribution and reduced sorbent efficiency.
Injection System: The injection system must provide consistent and controlled delivery of the sorbent. This often involves specialized equipment such as pneumatic conveying systems or screw feeders, capable of handling the material's properties and ensuring uniform dispersion. System design needs to prevent clogging and maintain consistent flow rate.
Sorbent Particle Size and Distribution: The particle size distribution of T-2000 directly impacts its surface area and thus its reactivity. Optimizing this distribution is vital for maximizing pollutant capture. Too fine, and it can lead to increased pressure drop across the baghouse. Too coarse, and it reduces surface area, limiting efficiency.
Gas Velocity and Temperature: Both gas velocity and temperature in the ductwork influence the contact time between the sorbent and pollutants. Higher velocities can lead to less contact time, while higher temperatures can influence the sorbent's reactivity, potentially improving or hindering the process.
Pollutant Concentration and Composition: The concentration and composition of the pollutants in the flue gas influence the required sorbent dosage. Higher concentrations naturally require more sorbent, and different pollutants may have varying reactivity with T-2000.
Chapter 2: Models
Predicting the performance of T-2000 in a specific baghouse requires the use of mathematical models. These models often incorporate factors like:
Reaction Kinetics: Models need to account for the chemical kinetics of the reaction between T-2000 and the target pollutants. This is often a complex process involving multiple steps and influenced by temperature and concentration.
Fluid Dynamics: Computational fluid dynamics (CFD) simulations can be used to model the gas flow and sorbent dispersion within the baghouse system. This helps optimize injection points and system design.
Mass Transfer: Models need to account for the mass transfer of pollutants from the gas phase to the sorbent surface. Factors like gas velocity, particle size, and boundary layer effects play crucial roles.
Empirical Correlations: Empirical correlations based on experimental data can be used to estimate the capture efficiency of T-2000 under different operating conditions. These correlations are often developed using experimental data from pilot-scale or full-scale studies.
Sophisticated models can integrate these aspects to predict pollutant removal efficiency, sorbent dosage requirements, and pressure drop across the baghouse system. These predictions are essential for designing efficient and cost-effective pollution control systems.
Chapter 3: Software
Several software packages are used in conjunction with T-2000 applications for design, simulation, and monitoring. These include:
Computational Fluid Dynamics (CFD) Software: ANSYS Fluent, COMSOL Multiphysics, and OpenFOAM are commonly employed for simulating gas flow patterns and sorbent dispersion within the baghouse system. These simulations help optimize the injection system design and placement.
Process Simulation Software: Aspen Plus, Pro/II, and similar software packages can be used to model the overall process including the gas stream composition, pollutant removal, and energy balances.
Data Acquisition and Monitoring Systems: Various software packages interface with sensors in the baghouse to monitor key parameters like pressure drop, temperature, and sorbent flow rate. This real-time data helps optimize operation and prevent problems.
Specialized Dry Sorbent Injection Software: While not a widely available standalone category, some vendors offer specialized software for simulating and optimizing dry sorbent injection into baghouses. These tools typically incorporate models specific to the sorbent's properties and the baghouse design.
Chapter 4: Best Practices
Effective utilization of T-2000 requires adherence to best practices:
Proper Selection: Careful consideration of pollutant characteristics and gas stream conditions is essential to ensure that T-2000 is the appropriate sorbent. Its effectiveness varies depending on the specific pollutants present.
Dosage Optimization: Determining the optimal sorbent dosage requires careful balancing between efficiency and cost. Excessive dosage can be wasteful, while insufficient dosage will not achieve desired removal.
Regular Maintenance: Regular maintenance of the baghouse system, including filter bag replacement and hopper cleaning, is crucial for optimal performance. Clogged filters or full hoppers can hinder the process.
Safety Procedures: Handling dry sorbents like T-2000 requires adherence to strict safety protocols to prevent respiratory issues and other hazards. Proper personal protective equipment (PPE) is mandatory.
Waste Management: A plan for the safe and environmentally responsible disposal or recycling of the spent sorbent is vital. This is often regulated, and proper procedures must be followed.
