  • A typical binary distillation column and related equipment

    The relationship between the reflux ratio, R, (cooling water = cw) and reboiler (steam) are given bywhere λV is the latent heat of vaporization (kJ/kmol) of benzene at its normal boiling point, and V (kmol/h) is the total vapor flow from the top of the column. The purchase cost of the column is given bywhere Vcol = πD2L/4 is the volume of Learn More

  • Forced circulation boiler - Wikipedia

    In water tube boilers, the way the water is recirculated inside the boiler before becoming steam can be described as either natural circulation or forced circulation. In a water tube boiler, the water is recirculated inside until the vapor pressure of the water overcomes the vapor pressure inside the stream drum and becomes saturated steam.Learn More

  • US4249486A - Steam condensate and waste water recycling

    Condensate released from traps on a chemical distillation reboiler is piped to a flash tank where steam is flashed off as condensate pressure is reduced. The steam is recondensed by contact with water obtained from heat exchangers and the condensate-water mixture collects in the flash tank where it may be pumped to a mixing tank remotely located at a steam boiler water purification plant.Learn More
