Are there devices similar to reflux condensers used in organic experiments in the chemical industry? The material should be 304 stainless steel. The temperature should be between 50 and 100 degrees, with a slight positive pressure. What is the name of such a device?
Coiled tubes have a larger heat exchange area compared to spherical tubes; in the chemical industry, condensers are sufficient~
Are there also condensers of this type that can be directly connected to equipment in the chemical industry? I want the condensed liquid to drip straight back into the equipment
For the intermittent production of fine chemical intermediates, the graphite condenser is either placed at an inclined angle or used in an upright position; the scale of such operations is relatively small, and no complex calculations are required. On a larger scale, it’s not common to have the condenser directly attached to the reactor – at least I’ve never seen that done. In such cases, condensation occurs first, followed by the material being fed into the reactor and then returning back
This is very common; any container manufacturing factory can produce it. Roll 1/2 inch of tube into a spring shape, insert it into a thicker tube with the ends sticking out on the sides, and then weld the upper and lower end caps – it’s a project that costs around ten thousand yuan
Mine isn’t very large either; I use it intermittently, so I don’t want to make too much of an investment
Is this considered a non-standard design? What is the common name for this type of device?
Then just try using a condenser~
Will this condensed liquid be carried away by the gas phase? If gas-liquid separation is not carried out
This is a coiled tube heat exchanger, which is very common. If one wants the gas to condense directly into a liquid state, in addition to considering the heat exchange area, it is also necessary to take into account the flow rate of the cooling source and the heating medium (such as ice water). If there are special requirements, consult the manufacturer for design. As for whether the condensed liquid will vaporize once it falls, it depends on the environment in which it lands, and it’s not something that can be explained in just a few words.
If there is a concern that heat exchange may not be sufficient, frozen brine can be used as the medium. I tried this during pilot tests a long time ago; methanol and dichloromethane can be condensed. In cases where there is a gas-liquid mixture, or when the evaporation rate is high and the steam flow velocity is too great, it’s hard to say whether the uncondensable gases will be carried away
