Niacin pipeline crystal blockage
Thread Content
Let’s discuss possible solutions for blockages in nicotinic acid pipelines, drawing on everyone’s experience!
Local blockages can be heated using an oxy-acetylene torch, while longer pipelines can be cleared with low-pressure steam.
Is this situation common? Is the low temperature duration long? If necessary, provide heat tracing.
After it gets clogged, we flush it with hot water (the system generates hot water). Under normal circumstances, as long as the insulation is proper, the system should not get clogged during continuous operation. Due to poor market conditions for nicotinic acid, it is produced in batches over extended periods of time; each time production of nicotinic acid is halted, we flush the related pipelines using 93% acid, and this yields good results. ,
Adjust the angle of the pipe appropriately; additionally, create a small hole when the machine is stopped, so that it is easier to use objects such as iron rods to push things inside the bucket. You may also refer to \"Sulfuric Acid Production Technology\"
