Catalyst for exhaust gas treatment equipment Equipment Design Department of Company Q, a automotive parts manufacturer
High-temp operation damages catalyst
Heat-resistant exhaust catalyst solves key issue
Company Q is doing well in the manufacture of automotive parts. The factory is operating at full capacity, and there are plans to increase production in the near future and expand various facilities. Under these circumstances, the facility design department is struggling with how to treat exhaust gases containing volatile organic compounds (VOCs).
Challenges
The concentration of VOCs emitted fluctuates greatly, and the catalytic combustion temperature of exhaust gas treatment equipment becomes higher more frequently.
The problem was the treatment of exhaust gases containing large amounts of VOCs that are emitted during the firing process in manufacturing.
Mr. M, who was in charge of this matter in the Equipment Design Department, was discussing ways to deal with the issue with his team members.
"We use catalytic combustion equipment to treat exhaust gas, but the concentration of VOCs emitted fluctuates greatly. As a result, when the VOC concentration is high, the catalytic combustion temperature rises, sometimes reaching 700°C," says Mr. M.
Because the catalytic combustion temperature was becoming higher more frequently, catalyst deterioration was also occurring much faster than before. This resulted in a sudden increase in the frequency of catalyst replacement, which led to increased downtime and complicated management, which became problems on-site.
Confused, Mr. M contacted the exhaust gas treatment equipment manufacturer, but was told that there were currently no options available that could handle high-temperature conditions where the catalytic combustion temperature exceeded 650°C.
Mr. M had been hoping for a response from the manufacturer, but after hearing this explanation, he began to think that he had no choice but to give up on solving this problem.
Key Challenges
The concentration of VOCs emitted fluctuated greatly, and the catalytic combustion temperature sometimes reached 700°C.
This caused catalyst deterioration to occur quickly, and the need for frequent replacement increased downtime and made maintenance more complicated.
The exhaust gas treatment equipment manufacturer used by Company Q did not have any catalyst options that could withstand high temperatures exceeding 650°C.
