Seeking help regarding the issue of water injection

Water injection mainly has requirements regarding chloride ions; it seems that ammonia nitrogen has not been analyzed. .

It mainly comes down to chloride ions; the purified water has an unpleasant odor. In case of leaks, the on-site environment needs to be taken into consideration, but it is used in large quantities

The main purpose of water injection is to wash away ammonia hydrosulfide and ammonium chloride; therefore, there are limits on the chloride ion content in the water. There are no strict regulations regarding ammonia nitrogen. The purified water you mentioned can generally be used as well, but its proportion should not exceed 30% of the total amount required. It is advisable to use deionized water or condensed water in order to control the chloride ion and oxygen contents, thereby preventing scaling and corrosion

I have some different opinions. The water injected into our system is primarily used for water purification, with desalinated water serving as a supplement when there is not enough of it. The source of the purified water is treated acidic water, which in turn comes from the water generated during the deoxidation reaction as well as the desalinated water injected into the system; therefore, the chlorine content should not be very high. The purpose of injecting water during the reaction is to remove hydrogen sulfide and ammonia from the circulating hydrogen, so it is necessary to control the ammonia nitrogen content in the purified water to prevent it from affecting the efficiency of the purification process. We generally keep this level below 100 PPM. As for the chlorine content in the purified water, it has not been measured very often. Regarding what the experts have said about high chlorine levels combined with ammonia to form ammonium chloride crystals that can clog pipes, this is indeed a possible problem. However, I believe that since both the raw materials and the desalinated water have their chlorine content under control, it is necessary to measure the ammonia nitrogen content in the purified water. As for the chlorine content, it depends on the actual situation – if the chlorine content in the raw materials is high, then it is necessary to measure it

It’s a bit messy written; please forgive me, teachers

Isn’t the purpose of adding water to prevent the formation of ammonium salts?

Water injection is used to remove ammonia nitrogen from the oil; perhaps water with low ammonia nitrogen levels will result in a better cleaning effect. High chloride levels can easily cause pipe corrosion
