The main pipe contains high levels of acetylene

After the monomer flow rate increases, the acetylene level in the main pipe rises – how to deal with this?
Reply to 1# Riverbank Fireworks: reduction in volume, mixing ratio. Check the converter hot water flux.
Is the catalyst expired? Be sure to replace the catalyst in a timely manner
After the flow rate is increased, the crude monomer contains high levels of acetylene, resulting in a reduced reaction conversion rate. Why is the conversion rate decreasing? A low reaction temperature, poor catalyst performance in some converters, an improper ratio of hydrogen chloride to acetylene, or reaching the maximum capacity of the production facility – any of these could be the cause.
Check whether too much excess from individual units is being carried over to the main pipeline; in some cases, poor catalyst installation causes the tubes in the converter to remain empty or insufficient acetylene is filled, leading to incomplete reaction
