The three different types of sulfur trioxide in the chemical role are the same, but the chemical activity of the Y type is stronger, andaThe type is the weaker one, but they are easily dissolved into concentrated sulfuric acid and can be used as oxidizing agent. Their chemical properties are the same as sulfuric acid, and they can also react strongly with water to generate sulfuric acid, and Chancheng has a lot of heat. Soliquid sulfur trioxideHow do you need to transport? What should I pay attention to when transporting? Follow Xiao Bian to have a look.
Generally, it is packed with tankers or steel cylinders, but the exhaust of the packaging container needs to go through a sulfur trioxide scrubber and absorb the sulfur trioxide in the exhaust with 98 sulfuric acid. The tanker or cylinder needs to be loaded under negative pressure. The storage tank needs to have a safety valve, and a thermometer should be installed to check the temperature of sulfur trioxide at any time to avoid low-temperature polymerization and curing.
liquid sulfur trioxidePay attention to these when transporting:
The railway transportation shall be carried out in accordance with the provisions of the dangerous goods loading table in the "Dangerous Goods Transport Rules. The packaging should be complete at the beginning of transportation and should be safe at the time of loading. Liquid sulfur trioxide in the transport process to ensure that the container can not leak, do not collapse, can not fall, can not be damaged. It must be prohibited to mix with flammable or combustible items, as well as reducing agents, alkalis, active metal powders and edible chemicals. During transportation, attention should also be paid to the transportation vehicles to be equipped with leakage emergency treatment equipment. During transportation, it should be protected from sun exposure, rain and high temperature.liquid sulfur trioxideRoad transport is to follow the prescribed route, do not stay in residential areas and densely populated places.
