What is the difference between dry acetylene and wet acetylene?

The advantages of dry-process acetylene over wet-process acetylene are as follows: 1. It eliminates the need for a pressure filtration stage, thereby reducing the number of workers required. 2. In the dry process, a slightly larger amount of water is added than theoretically necessary, so the slag produced is in the form of powdered Ca(OH)2, which helps to reduce pollution. In contrast, in the wet-process acetylene method, a large amount of water is added, resulting in slag that is in the form of a slurry of Ca(OH)2. It exacerbates environmental problems, which is the biggest issue with the wet method. 3. Since Ca(OH)2 is in powder form, it can be used directly as a raw material for calcium carbide production, thereby saving costs. 4. The dry method for producing acetylene requires calcium carbide of a much finer particle size than that used in the wet method; calcium carbide powder can be utilized, which helps reduce consumption and lower production costs. 5. Less water is needed, thus conserving water resources. However, the dry method for acetylene production has its drawbacks: 1. There are no manufacturers of generators in China, so imports from abroad are necessary, resulting in high investment costs. 2. Controlling the temperature at high levels poses safety risks, and high skills are required from the operators. 3. The technology is not yet fully developed in China. 4. High standards are required regarding the particle size of calcium carbide, which in turn means higher demands on crushers. 5. If the calcium carbide particles are too fine, bonding may occur during the production process, similar to what happens in polymerization reactors. 6. There are also issues related to the transportation of calcium carbide residues. Nevertheless, the overall advantages are significant, and this represents the trend in the development of calcium carbide-based production methods. But for now, everyone is waiting to see how things develop. Our factory also wants to get involved in this project, but after examining the situation, we think it’s better to wait
