Oxidative synthesis of glyphosate
Thread Content
The oxidation tank is equipped with coils and a jacket for cooling; 10-degree water and circulating water are used respectively. Each time, a large amount of buildup (glyphosate crystals) is found on the coils, which is likely due to an excessive temperature difference. The normal operating temperature should be around 50 degrees. Could it be considered to switch to using circulating water for cooling the coils? Is this feasible? Looking forward to your guidance!
It depends on the process temperature and the area of the coil, I guess
My humble opinion: Does the use of circulating water mean that the inlet temperature has increased? Does that mean that as long as you increase the flow rate so that your temperature control can meet the requirements, it will be fine? Or do you have other concerns?
We are just circulating water, and we use half-pipes
Is the coil of the cooling crystallization tank corroded? If not, try not to touch the existing coils (the process parameters are already set). Also, there are cleaning equipment (both mobile and fixed types) that can be considered for purchase depending on the circumstances.
