Treatment methods for high system resistance and the formation of ammonium carbonate crystals!
Thread Content
We’re injecting water into the system – has that happened to you guys?
Liquid ammonia can be used for dissolution; specifically, this involves raising the liquid level in the ammonia cooler while monitoring the temperature of the synthesis tower
Should water be added while driving or while parked? It should be said that it is not allowed to add water while driving. When stopping, water is added; the synthesis tower can then be disconnected and boiled using steam.
Reply 1# pdslht: I’m not sure what system it is Inside the pipe? Still inside the device? The formation of ammonium carbonate crystals is certainly due to excessive levels of ammonia or CO2; it is necessary to bring either ammonia or CO2 back within the limits specified by the process requirements, in order to prevent further crystallization or clogging. Regarding processing, some systems can involve temporarily raising the temperature of the medium; this allows the crystals to be gradually melted without shutting down the system, while still ensuring normal production ； In some systems, the operation must be stopped for handling; pipeline crystallization can be removed most quickly by steam purging, while equipment needs to be filled with hot water for boiling. Ammonium carbonate crystals melt when exposed to steam or hot water. It’s easier to deal with if it’s not blocked, but once it is blocked, it becomes difficult to handle.
Both systems of mine have experienced water injection; I connected them again today, and the problem was resolved right away
Do ammonia washing! Be careful not to cause overpressure; it’s best to do this while reducing the volume, and make sure the circulator doesn’t suffer from liquid slugging. . . Controlling the liquid level isn’t a major issue; the key is to manage CO, CO2, H2S, etc. in the upstream section – these are used in the synthesis process. Overheating or overpressure can also occur in the compressor’s cooling system, so reduce the water flow rate of the cooler as long as there is no overheating or overpressure in the next stage! Raise the temperature! These are all temporary fixes that do not address the root cause. . . . To address the root cause, we must start at the source!
Are you referring to synthetic positions? If it’s a high-pressure, low-temperature system, a thermal wash will suffice
