  • Patent number: 11028046
    Abstract: The present invention relates to a toluene diisocyanate purification method enabling acquisition of a product having a small amount of dimers in a final product by means of using a reactive dividing wall column during toluene diisocyanate preparation. More particularly, according to the present invention, in order to obtain a product having a small amount of dimers in accordance with a reversible reaction of a monomer and a dimer, a purification procedure is designed by means of applying the temperature, pressure, time of stay and the like of a reactive dividing wall column as appropriate particular conditions, a reboiler having short time of stay and high heat transfer rate is used, and thus a dimerization reaction is inhibited and the purity and yield of the product are enhanced. Therefore, high-purity toluene diisocyanate can be purified and obtained.

  • Patent number: 11027984
    Abstract: A process for producing urea with controlled excess of CO2 and/or NH3. The process includes the steps of: reforming the hydrocarbon feed gas, thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O, shifting the synthesis gas, removing CO2 from the synthesis gas, removing residual H2O and/or CO2 from the synthesis gas, removing CH4, CO, Ar and/or He, and adding stoichiometric nitrogen to produce NH3 to the synthesis gas, synthesizing NH3 to obtain a NH3 product, and adding at least part of the product CO2 and at least part of the NH3 product to a urea synthesis step to make a urea product. The amount of excess CO2 and/or NH3 is controlled by adjusting the steam/carbon in the reforming step and/or the H2O addition upstream the shift step and/or adjusting the inlet temperature to at least one or more shift steps.
