Absorption of coal tar volatiles
Thread Content
The gases emitted from the coal tar storage tanks (a mixture of polycyclic aromatic hydrocarbons containing carcinogens such as benzo[a]pyrene, BaP) pass through a scrubber, where the organic volatiles are absorbed by the circulating washing oil. I would like to ask the experts: what is the medium that can absorb the volatiles from coal tar? I earnestly ask for guidance from experts everywhere! ! Thank you
What a cute child :) Just chatting. :Victory: The gases emitted from coal tar storage tanks (a mixture of polycyclic aromatic hydrocarbons, including benzo[a]pyrene (BaP)) can be recovered using solution-based containers. A simple approach (non-standard) is to direct the gas emitted from the coal tar storage tank through pipes into the solvent recovery tank; the solvent can be a light solvent such as C8, C9, etc
Hehe, thanks for the advice. C8 aromatics are a type of xylene; if they are stored in a tank area, many factors such as fire prevention, toxicity, and explosion thresholds must be taken into account. Since the tank areas are located in the port, will the approval procedures be complicated in the future? Is there a better solvent oil? Here there are two storage tanks with a capacity of 5,000 cubic meters each, and the circulation rate of the solvent oil is 20 cubic meters per hour. I’m not sure how often the C8 solvent needs to be replaced; does this mean that a temporary small storage tank for the solvent oil needs to be built in the tank area as well? Can used solvent oil be recycled and reused? Please give your advice!
Benzene is not necessarily required; solvent oils or alkanes can be used instead.
