For example, if nitric acid were to be used, relatively high-quality waste acid
used for cleaning electronic printed circuit boards could be obtained.
However, the most of these catalytic reactions suffer from environmental pollution of waste acid
,high reaction temperature, complicated and time-consuming process.
1) collection, disposal of waste acid
(1 not defined Unit)
Tainted sediments from the Kromma Kill were to be removed along with the two waste acid
pits and leaky underground fuel oil tanks.
2] recovery unit at the waste acid
neutralization plant in 1998, a titanium oxychloride (TiO[Cl.
The company also engages in the provision of recycling services for sulfuric waste acid
The conventional process for producing MMA uses highly toxic chemicals and produces waste acid
that has to be safely recovered.
The acid regeneration plant, which will re-process the hydrochloric acid used in the pickling process, is designed to treat 12,000 litres (3,170 gal) per hour of waste acid
The CO2 EOR pilot project will inject into reservoir a combination of acquired CO2 with waste acid
gases from the Judy Creek Gas Conservation Plant to cause additional hydrocarbon recovery.
Provided that they do not contain any metal complexes, basic inorganic liquids (including developer, fixing baths, soap solutions, surfactants, wash water) are routed to a continuous-flow neutralization system operated with waste acid
, milk of lime and FeC13.
While the use of lead acid batteries is commonplace, they can present some problems in Arctic regions such as Nunavut, particularly concerning the disposal of spent batteries, neutralized waste acid
and battery components.
This is much more ecologically effective than the traditional method of having the waste acid
trucked to disposal facilities or neutralized and then discharged into the company's waste stream.
