Water injection into the hydrogenation unit?
Thread Content
What is the indicator for water injection in hydrogenation units? Can purified water obtained through acidic steam stripping be used instead?
Hydrogenation units can use purified water; that’s what our company does. From the perspective of energy savings and reduced consumption, it’s sufficient to control the chloride ion level.
The purpose of adding water is to prevent the crystallization of ammonium salts; the goal is to ensure that the ammonium salts remain in an unsaturated solution at that temperature, with the concentration generally kept at no more than 5%.
Sure, but pay attention to the quality. We’ve been using it, though the inlet filter of the high-pressure pump keeps getting clogged; so we added two sets of filters to the inlet pipeline!
The water injection volume is 5 to 10 percent of the device’s processing capacity. My device was originally designed to use acidic water for injection, but this method was discontinued due to poor quality of the water.
Hydrogen-producing acidic water can be used as hydrogen injection water, but it must be thoroughly stripped and treated with chemicals before use. The medication must be kept away from air, otherwise it tends to oxidize and clump together.
Yes, it’s possible to control the chlorine content; it’s best to install a filter.
The quality of the purified water must be carefully monitored, especially with regard to chloride levels. It is necessary to pay attention to the source of wastewater undergoing acidic water treatment in order to ensure that the quality of the purified water meets the required standards; large-scale refineries can handle acidic water separately when this is possible.
It should be possible. Our system uses desalinated water, condensed water, and purified water for injection, but at present we mainly use desalinated water, with the injection volume being around 5% of the processing volume; this is done to prevent ammonium salts from crystallizing and blocking the pipes.
Yes, but it is necessary to ensure that the levels of other ions in the water are low and that there are few impurities.
