Abstract
Description
- This invention uses only a high-speed intensive mixer to produce humic acid salts by a single step completing any of following chemical reactions:
-
R—COOH+NaOH=R—COONa+H2O -
R—COOH+KOH=R—COOK+H2O -
R—COOH+NH4OH═R—COONH4+H2O - The basic principle of the present invention is different from the traditional fluidized bed, which only utilizes high speed agitation instead of large amounts of gas to fluidize solid powder. In practice, however, one or more alkali hydroxide (including potassium hydroxide, sodium hydroxide, or ammonium hydroxide solution, etc.) can be added to react with any of humic acid sources.
- There are many unique technical advantages of the present invention over the traditional such as those were claimed by Patent CN101544675B. The most noticeable differences are:
- 1. This invention utilizes only the high-speed agitation instead of the standard fluidized bed which requires a large amount of gas to fluidize the solid powder.
- 2. The present invention utilizes reaction heat and friction heat to evaporate excess water for keeping the reaction temperature and drying product simultaneously. The conventional method will require a lot of extra steam to maintain the reaction temperature.
- 3. The present invention is a dry process achieving a complete reaction with very little additional water. On the contrary, the traditional method requires a lot of water to dissolve caustic soda before mixing with humic acid becoming paste state followed up with more complicated steps.
- 4. In the present invention, the flow pattern is very vigorous by thoroughly mixing the solid ingredients to achieve a rapid reaction that can be completed in less than 20 minutes vs. 20-26 hours claimed by Patent CN101544675B.
- Technical specification of the basic principle behind the present invention is due to the large contact area of the ingredients created by high-speed mixing and the neutralization reaction carried out both on surface and inside of powders. In the meantime temperature raises rapidly making caustic flake to melt and then start to penetrate into humic acid powders by osmotic pressure.
- This invention uses the frictional heat and exothermic heat generated by the reactants to control the reaction, maintain more stable quality, and most importantly save a lot of energy for steam injection. Additionally, all chemical reactions take place under fluidizing conditions, any excess of water contained in the mixture of solid phase (˜30% water) can be evaporated, therefore eliminating the follow up product drying and grinding steps.
- Three experimental tests were conducted under the setups in accordance with the concept described in this invention. Typical test conditions and the results obtained are shown in the following examples:
-
- Equipment: High speed intensive mixer (Henschel brand)
- Capacity 200-500 Liter Agitator speed 500-1500 RPM
- Recipe: Humic acid: (Purity 44% Water content 24%) 100 kg 90% Potassium hydroxide: feed slowly 13.3 kg

- Equipment: High speed intensive mixer
- Capacity 200-500 Liter Agitator speed 500-1500 RPM
- Recipe: Humic acid: (Purity 44% Water content 24%) 100 kg 35% Ammonium hydroxide (Under pressure spray mode) 21 kg

This invention uses a high-speed intensive mixer to promote chemical reaction between alkali hydroxide (Including potassium hydroxide, sodium hydroxide, or ammonium hydroxide solution, etc.) and any substances contain humic acid. The new process quickly makes a dry product in a solid phase fluidized bed type reactor and can replace the traditional manufacturing procedure with significantly higher efficiency and cost benefits. It also addresses the common public concerns on the safety and pollution problems.
- By employing a high-speed blender alone, the new process generates a vigorous powder flow and a series of unit operations, including crushing, mixing, as well as dissolution, neutralization and evaporation due to friction heat; the reaction temperature can thus be automatically controlled. What are claimed in this invention includes but not limited to the following:
