  • Acid Recovery
    on the reduction of acidic waste streams through recovery and purification using evaporation and distillation technologies.
  • ACID SEPARATION FOR IMPURITY CONTROL AND ACID RECYCLE USING SHORT BED ION EXCHANGE
    , nitric, and hydrofluoric. In the case of hydrochloric acid, the process can. selectively separate chloro-anionic complexes such as Zn, Pb, and Cu, which are then eluted with. water. The acid recovery technology can also be closely coupled with ion exchange processes in. order to minimize
  • Recovery of Precious Metals
    Level Indicator compatible with phosphoric acid and sodium cyanide is used for recovery of gallium and silver.
  • Zirconium in Nitric Acid Applications (.pdf)
    , synthetic fibers, metal pickling and the recovery of uranium. As the demands on nitric acid process equipment have increased, material selection for that equipment has become crucial. Suitable structural materials need to be cost effective, reliable, durable, efficient, and non-contaminating
  • THE IMPACT OF ACID GAS LOADING ON THE HEAT OF ABSORPTION
    In amine sweetening units, the heat of absorption and VOC and BTEX solubility have been found to vary significantly with acid gas loading as well as with temperature, amine type, and amine concentration. The heat of absorption declines by up to 20% while VOC and BTEX solubility can drop by as much
  • Tuning in to New Solvents
    that can combine synthesis and product recovery in a simplified and efficient one pot system. which offers organic solubilities and the potential for reversible acid/base catalysis. or water-soluble catalysts (including both aqueous organometallic complexes and enzymatic biocatalysts) that can
