Sodium Formate Green Preparation

Sodium Formate Green Preparation

Technical content:

The green preparation technology of sodium formate is achieved by recycling and utilizing the tail gas from the liquid nitrogen washing process of a large synthetic nitrogen device. It reacts with a certain concentration of sodium hydroxide solution at a certain temperature and pressure to generate a sodium formate solution, which is then concentrated, centrifuged, and air dried to achieve a high-purity sodium formate product

Innovate

1. The process technology of new sodium formate has a short production process, low energy consumption, low cost, and high product quality, achieving green preparation of sodium formate

2. The production of sodium formate can be flexibly adjusted by adjusting the CO content in the conversion process of the synthetic nitrogen system, achieving the comprehensive utilization of resources in coal chemical production units and chlor alkali chemical production units.

3. Improved the conversion rate of carbon monoxide and the quality of sodium formate, with a CO concentration of less than 10PPM in exhaust emissions and a sodium formate content of ≥ 99.0%

4. Develop a continuous evaporation process with one drag two dual effect concentration to continuously extract sodium formate, achieving low product energy consumption, simple operation, and safety

5. The device adopts dual effect evaporation and steam drying crystallization technology, and the project achieves comprehensive utilization of energy such as reaction waste heat and residual pressure. The production cost is low, and there is no "three wastes" generated throughout the entire production process.

6. By utilizing computer control technology and a dual safety interlock system, the problem of long-distance safe transportation control of raw gas has been solved, improving the intrinsic safety of the device, and achieving the optimal synthesis ratio of carbon monoxide and caustic soda solution at all times
