Can the purified water produced from acidic water replace the deionized water used for alkali washing after sulfur exhaust gas treatment? ? I earnestly ask all the experts for their guidance
It depends on the quality of the water you purify; oils and impurities can easily cause blockages and reduce the efficiency of absorption
The purified water produced from acidic wastewater generally cannot replace the alkaline solution used for the alkali washing of sulfur exhaust gases. In addition to the factor of removing impurities such as oil from the water, some water-soluble salts that react with alkalis, as well as unwanted gases, are also among the causes. For example, HN4Cl and (NH4)2SO4 react with NaOH to produce NACl and release NH3 ; Wait.
For petrochemical companies, purified water generally contains oil
I use the old alkali washing process here, and I plan to use purified water to wash hydrogen sulfide. Both sulfides and ammonia nitrogen in the circulating water are below 20, with no oil present. Does anyone have a precedent like this? ? ?
Use purified water instead of deionized water for watering the alkali scrubber tower to wash away hydrogen sulfide.
It can be used in short cycles, which helps save energy
It depends on what your purified water parameters are. If all the purified water is introduced, there is no major problem; however, if only a small amount enters, it will increase the levels of ammonia nitrogen, COD, and sulfides, causing the parameters to fall below the required standards.
