1. Company name and scale 2. Reaction temperature for the low-temperature conversion of potassium chloride 3. Number of stages in which the reaction takes place 4. Conversion rate of potassium chloride; what level of chloride content is required in the product
1. Company names: Scale Compound Fertilizer (15-15-15 sulfur-based); Red Sun Group – 700,000 tons per year; Shikefeng – 600,000 tons per year; Sinochem Shandong Fertilizer Industry – 600,000 tons per year. 2. The reaction temperature for the low-temperature conversion of potassium chloride is 110–130°C. 3. The reaction takes place in two stages (in square tanks). 4. The conversion rate of potassium chloride is approximately 80%, with the chlorine content in the product kept below 3%. Last edited by bht11 on 2008-2-19 at 08:11

Company name: Jinan Chemical – 200,000 tons per year production capacity. The reaction temperature for the low-temperature conversion of potassium chloride is 115–125°C. The reaction takes place in two stages, with a conversion rate of approximately 83% for potassium chloride. The chlorine content in the product is kept at around 3%
In fact, for low-temperature conversion, a three-stage or four-stage reaction process yields better results. However, most enterprises in China have followed the approach used by Hongri; Hongri uses a two-stage process, and so others have also adopted this two-stage method without conducting any separate calculations. As a result, the conversion rate is not high, and the level of chloride ions cannot be reduced. Typically, the conversion rate is around 80%, with chloride ion levels ranging from 2.5 to 3.0.

Our factory used to produce it, but production has been halted and it has been replaced by sulfur-based compound fertilizers
