CIRCULAR ECONOMY SOLUTIONS FOR PROCESSING & MANUFACTURING KOH

Recovering valuable byproducts and recycling materials that would otherwise be discarded as wastes, while meeting ever-stringent environmental requirements, is a critical strategy in driving the industrial circular economy .Veolia’s potassium hydroxide (KOH) processing and manufacturing facilities provide a reliable source of KOH for industrial users, including petroleum refiners running HF alkylation units.
 
From two merchant KOH processing facilities in the Gulf Coast, and other dedicated plants located at customer sites, Veolia’s proprietary technology and its operational expertise are applied to manufacture KOH, using potassium fluoride (KF) as a feedstock. Under applicable regulations, when the KF is properly used in this manner, it is no longer considered a waste – a win-win for generators, producers and users alike.
 
In this closed loop system, on-spec KF streams are delivered to one Veolia’s KOH processing plants, where it is used to manufacture KOH that is returned to industrial customers for use in their processes. 
 

HARDTAC® CRYSTALLIZATION TECHNOLOGY 

Veolia utilizes the HARDTAC® Process, a proprietary crystallization methodology, in its KOH manufacturing process. HARDTAC stands for High Aspect Ratio Draft Tube Agitated Crystallizer. The unique design yields larger particles and higher solids concentration than conventional crystallization processes providing environmentally friendly residuals. 

BENEFITS

The benefits of manufacturing KOH from KF streams include:
  • Offers a lower cost alternative to virgin KOH reagent
  • Delivers a reliable source of reagent meeting consistent quality specifications
  • Reduces total on-site neutralization process requirements and subsequent loading on downstream waste treatment (when properly used as a feedstock, the KF is not a waste)
  • Reduces environmental impact through the recycle of waste products
  • Simplifies waste treatment for HF alkylation facilities and improved focus on core processes

FEATURED PROJECT

Many industrial processes use a hydrofluoric acid (HF) catalyst in their manufacturing process. Part of this acid must be neutralized with a base chemical, often potassium hydroxide (KOH). Typically, the resulting material, potassium fluoride (KF), must be classified, handled, and disposed as a hazardous waste. The Veolia team, however, developed an innovative solution that uses KF as a feedstock in the manufacturing of KOH. When the KF is properly used as a feedstock for this process, it is no longer classified as a waste. Learn more about the environmental and economic impact of applying this KOH processing solution.
