Ammonium Thiosulfate (ATS) via Continuous Processing:
Process technology has been developed by K-Tech for the production of ammonium thiosulfate (ATS) using anhydrous ammonia and sulfur as the primary raw materials. In the process approach, molten sulfur is fed into a proprietary reaction system and combined with ammonia and various sulfur species to produce an ammonium thiosulfate product.
From an overall standpoint, the reaction can be illustrated as follows:
2 NH3 + SO2 + S + H2O → (NH4)2S2O3
The process is carried out in an aqueous environment and control of the reaction approach allows for the production a high quality ATS with minimal sulfate content. This is important from the standpoint of having a material that is ideal for high sulfur fertilizer products.
Compared to conventional methods, the K-Tech process allows for straightforward production of ATS with minimized environmental impact and sulfate concentration. There are no by-products associated with this system, and the approach allows for minimized maintenance costs.
