In 2015 EBNER was awarded the contract for planning and delivering several plants for evaporation and vacuum-cooling crystallization from brine for installation site in LAOS by an EPC on behalf of a stated-owned enterprise.
The plant projected by EBNER is part of a green-field-project for the production of different salts which find application – after several intermediate steps and conversions – as fertilizer potassium chloride (KCl) and table salt (NaCl).
In the first step brine is obtained due to cavern dismantling and mixed salt achieved by evaporating of water and exceeding of the solubility of a part of the salts in three parallel triple-stage evaporation crystallization plants. The salts, mainly NaCl and KCl, are separated and partly solved again by production of a hot solution. Thus high-purity food salt is produced. The solution arising in the described plants is concentrated in a further double-stage evaporation crystallization plant and as a result a further mixed salt, mainly Carnallit and NaCl is obtained. This is returned into the triple-stage plants again and converted.
After that the hot solution is cooled-down in a seven-stage vacuum-cooling crystallization which is operated in accordance with the principle being typically applied for the KCl-production. Since the solubility of KCl decreases when the temperature is dropping a progressive crystallization of salt takes place by a progressive temperature reduction. This salt is given from the last stage to the salt separation and drying.
The plant components designed by EBNER form the core of the entire plant. The order was placed with EBNER primarily due to the low energy consumption within the frame of the highly efficient heat recovery and the trust of the customer in the quality of EBNER.
