| titleOfInvention | Sodium carbonate-vinyl chloride coproduction technique based on ammonium chloride chemical looping |
| abstract | The invention discloses a sodium carbonate-vinyl chloride coproduction technique based on ammonium chloride chemical looping, which comprises the following steps: reacting a carrier and ammonium chloride to absorb hydrogen chloride and release ammonia gas; heating the carrier absorbing hydrogen chloride to release hydrogen chloride; reacting the obtained ammonia gas with a sodium chloride water solution and carbon dioxide to generate sodium carbonate, wherein the byproduct ammonium chloride is recycled; and reacting the obtained hydrogen chloride with acetylene to generate vinyl chloride, wherein the byproduct carbon dioxide in the acetylene preparation process is recycled for sodium carbonate production, and the carrier after releasing the hydrogen chloride is recycled. The ammonium chloride chemical looping technique integrates the existing sodium carbonate and vinyl chloride production techniques, solves the problem of ammonium chloride circulation, and is hopeful to implement low ammonia or zero ammonia consumption in the sodium carbonate technique; the sodium carbonate and vinyl chloride techniques are simplified, thereby greatly lowering the cost investment and energy consumption; and the technique reduces the emissions of CO2 and solid wastes in the production process, and obtains light calcium carbonate with high added value. |
