    Ordinarily, the steam sides of reboilers and surface condensers are clean. The usual steam side fouling factor of 0.0005 to 0.001 is normally sufficient to allow for the steam side fouling with silicates and carbonates. However, there is another type of temporary fouling that …Learn More

  • 【steam】75 - 24H

    23/2/2004 · The controls will ask for more steam flow and increase the amount of blow through. Also maintaining a water level in the reboiler promotes corrosion and after a while you'll get a leak in the reboiler and something is going where it's not wanted.

  • Methods of Estimating Steam Consumption | Spirax Sarco

    rough guideline for setting reboiler duty in amine regenerators is to use a value from 120 and 180 kg of 3.5 barg steam per standard m3 of solvent (1-1.5 lb of 50 psig steam per standard USgal). Figure 3 shows the H2S and CO2 loadings produced over a tenfold range in solvent rates when the reboiler energy input is maintained at the somewhat high value of 200 kg of 4 barg steam per standard m3 of solvent …Learn More

    Improving heat transfer in reboilers and condensers. Condensing steam against the surface of clean, cold tubes of a water cooled condenser ought to produce an excellent heat transfer coefficient (U value). The author has observed coefficients as high as 300-350 Btu/h/ft2/°F. But, quite often, the U value is only 60-80, or even less.Learn More

    A kettle reboiler (Figure 10.1) consists of a horizontally mounted TEMA K-shell and a tube bundle comprised of either U-tubes or straight tubes (regular or finned) with a pull-through (type T) floating head. The tube bundle is unbaffled, so support plates are provided for tube support. Liquid is fed by gravity from the column sump and enters at Learn More

    Steam produced in any shell-type boiler, where the heat is supplied only to the water and where the steam remains in contact with the water surface, may typically contain around 5% water by mass. If the water content of the steam is 5‰ by mass, then the steam is said to be 95% dry and has a …Learn More

  • Improving heat transfer in reboilers and condensers

    A reboiler is a heat exchanger that is used to generate the vapor supplied to the bottom tray of a distillation column. The liquid from the bottom of the column is partially vaporized in the exchanger, which is usually of the shell-and-tube type. The heating medium is most often condensing steam, but commercial heat-transfer fluids and other Learn More
