The Research Of Caustic Soda Project Process

In the chemical industry, Caustic soda is basic chemical raw materials. This paper taking salt as raw material to produce the product caustic soda of ionic membrane caustic soda process design research project, to further optimize the entire process scheme proposed advanced, reasonable clean environmentally friendly technology. The main work is as follows:1. Determined the capacity of the project. Electrolysis of the salt water with the method of caustic soda, while it is also generates chlorine and hydrogen. In order to cope with the appropriate production capacity, we must find a suitable downstream products, to ensure safe and orderly production.2. Each step of the process route comparison, I will choose the most advanced and proven energy-efficient routings. This project began setting process from raw salt route, over a series of chemical reactions and physical reaction step, primary brine, secondary brine purification, electrolysis, dechlorination, hydrogen treatment, chlorine treatment, chlorine absorption, hydrochloric acid synthetic, liquid chlorine, evaporation processes, and ultimately put salt into caustic soda and produces hydrochloric acid and chlorine and other upstream products. Eventually the project achieved the purposes of clean, safe, energy-saving .It creating greater economic efficiency and enhance market competitive ness.3. I will choice of process routes for detailed analysis, selection and specifications of all major computing devices, and the overall project consumption calculation;4. I may appear in the project dangerous and harmful situation estimates, and design some safety measures;5. I carried out the project’s overall mass balance calculations, material balance diagram plotted the overall project. And the process of every working procedure diagram drawing and flow chart of pipeline and instrumentation, make a complete set of process route.6.I put forward some improvement, and detailed contrast.
