Conducting a ventilation assessment involves several steps: 1. Identify the Catalytic Processes: Understand the specific catalytic reactions and the types of gases involved. 2. Measure Existing Conditions: Use sensors to measure current levels of airflow, temperature, pressure, and humidity. 3. Evaluate System Design: Assess the design of the current ventilation system, including ductwork, fans, and exhaust points. 4. Analyze Data: Compare the measured data against optimal conditions for the catalytic process. 5. Recommend Improvements: Suggest modifications to the ventilation system to better meet the needs of the catalytic processes.
