Wine Acid Production
WINE ACID PRODUCTION AND WINE STONE PROCESSING
The answer to the question: “how to get tartaric acid from tartar?” Is not new enough. The standard technique has many steps, including: extracting potassium tartrate from tartar, processing it into calcium tartrate, then treating calcium tartrate with sulfuric acid. These processes are accompanied by periodic washing, filtration, evaporation, crystallization and recrystallization. In this way, you can get high quality tartaric acid.
However, the above processes are accompanied by a number of drawbacks, such as:
- large amounts of waste
- the need to use a number of reagents (sulfuric acid, calcium chloride, calcium carbonate),
- high energy costs for evaporation and recrystallization.
The question arises. Is there a way to avoid these difficulties and costs in the production of tartaric acid?
The answer is yes.
It exists only when using completely different approaches in production. This approach is the use of electrodialysis technology. The prospect of using this method is to avoid many stages that require high energy costs.
The essence of the method consists in dissolving tartar and removing potassium from its composition. Thus, in the process of electrodialysis, two substances are formed: potassium hydroxide and tartaric acid solution. At the same time, the purity of the tartaric acid solution is so high that it does not require additional recrystallization. This significantly reduces the energy costs of heating processes. The second advantage of this technology is the rejection of reagents, which are used in the standard technological process. These reagents require the cost of their purchase and are part of the by-products of production.
Thus, it is safe to say that the use of electrodialysis technology greatly simplifies and reduces the cost of the technological process of obtaining a solution of high-purity tartaric acid. It only remains to crystallize it. In the process of obtaining tartaric acid main consumables are tartar and electricity
