Heat exchange area of the first and second stage evaporation heaters in the 520,000-ton urea plant
Thread Content
The heat exchange area of the evaporation heater in the urea plant determines the system load and product quality. It is worth noting that for devices of the same capacity and type, the heat exchange area of their heaters can vary significantly, especially in the case of two-stage heaters. Please, fellow sailors, share your experiences so that we can all learn from them.
