Operating procedures for continuous distillation columns
Thread Content
I’m begging for help from all the experts here. I need to prepare this operating procedure urgently, but I’ve had little experience with continuous processes before. Please help me! Main description: Three-column continuous distillation, heat transfer oil heating, chilled water circulation. If any further information is required, please let us know.
There are also precautions, participants, and emergency plans for unexpected incidents that need to be included.
For your post, OP, unless someone already has it ready, writing it specifically for you might not be possible even if you stay up all night.
Does anyone have any available materials on continuous distillation? Anything related to it will do; I just want to use it as a reference
It is related to the product’s manufacturing process, factors such as the properties of the material used in distillation and the required specifications; it’s impossible to know how to write this without understanding the process
The process involves continuous distillation of trichlorosilane in three towers; an explosion-proof rating of d2ct4 is required at the site. The heating method is heat transfer oil heating. Melting point (at 101.325 kPa): -134℃； Boiling point (101.325 kPa): 31.8℃ ； Liquid density (0°C): 1350 kg/m3 ； Relative density (gas, air=1): 4.7 ； Vapor pressure (-16.4°C): 13.3kPa ； (14.5℃): 53.3kPa ； Ignition point: -27.8℃ ； Autoignition point: 104.4℃ ； Flash point: -14℃ ； Explosion limit: 6.9～70% ； Toxicity level: 3 ； Flammability rating: 4 ； Explosivity level: 2 Trichlorosilane is a colorless and transparent liquid that is highly volatile, flammable, and has an irritating, foul odor under normal temperature and pressure conditions. It burns very easily in air, and there is a risk of ignition even at temperatures below -18°C. When exposed to an open flame, it burns vigorously, producing red flames and white smoke; SiO2, HCl, and Cl2 are formed as by-products: SiHCl3 + O2 → SiO2 + HCl + Cl2 ； Vapors of trichlorosilane can form explosive mixtures with air over a wide range of concentrations, leading to violent explosions when heated. Its thermal stability is better than that of dichlorosilane; at 900°C, it decomposes to produce toxic hydrogen chloride fumes, as well as Cl2 and Si.
It’s three towers in a row; I’ve verified it. Thank you, moderator
