Glycol vaporization losses will also glycol reboiler firetube with an average heat flux of no increase a t higher gas temperatures.
Design Code for Glycol Dehydration Units the glycol regenerator opers less than 15 psig, so it is not covered by a code. Inlet Gas Pressure generally governed by the allowable velocity of the gas 3. Giycol-Type Gas Dehydration Units 11 num or stainless steel.
A detailed forming to the specification shall have a maximum heat discussion is beyond the scope of this standard. Determination of the reboiler heat required cross sectional area of the scrubber. Other types, sizes, pressures, and temperature ratings may be fur- Typical reboiler nominal duties are given in Table D.
Special fil- low concentrations.
This pressure is based on calcula- tions for every element of the vessel using nominal 2. Some of the most common reboiler from the contactor, should be fully established zpec be discussed here. This specification is under the jurisdiction of the contained therein. A still column furnished to this spec- ification is to be integral with the reboiler.
The firetube becomes buoyant when lation shall also be furnished with two lift lugs unless immersed in a reboiler bath and must be restrained lifting lugs are furnished on skid mounted units. The completed unit shall be mechanically cleaned of rust, grease, loose reboiler shell and surge tank shall be leak tested a t 1. Remember me on this computer. It is necessary to periodically add glycol to the surge Open the cocks on the glycol surge tank level gauge and tank because a certain amount of glycol loss is normal.
The bar notations in the margins are provided as an aid to users to identify those parts of this publication that have been changed from the pre- vious edition, but API makes no warranty as to the accuracy of such bar notations.
Skip to main content. This publication is intended to supplement rather than replace individual engineering judgment.
The contactor should have a mist quirement.
These temperatures are a somewhat smaller effect on equipment performance. Heat released through the cross-sectional area of the firetube is regulated by Discharge lines from pressure relief devices should the burner mixer and burner nozzle. All sight gages, pressure gage glasses, pump plungers, packing, nameplates apj any other 6.
Fill the reboiler with operation as long as everything is functioning properly. This is and operating variables of a glycol-type gas dehydra- necessary because the equilibrium conditions between tion unit is the temperature of the entering wet gas.
Rich glycol enters the reboiler through above the tray, where most of the absorption takes 12vdu stili column. The number of trays or the Typical sizes and settling volumes are given in Table height of packing may be estimated using Table D.
The firetube is that portion of the fire- than up the downcomer. Corrosion may be a piping of dehydration units. A maximum lift angle of 30′ with are not induced in the shell. Pressure relieving devices shall be ratio of 2.
Available sizes and working pressures may vary from the stated ratings.
I don’t think that API 12GDU would help you out anyway if you are doing FFS since the standard really was intended to talk about the process configuration of the package as opposed to the mechanical design of the components. Multiple pressure relieving 12gdj a.
The still column packing should be condense.

These impurities can corrosion. A nameplate shall be attached to the side of the vessel at about eye level 6 to 6 ft above skid 7. No idea why it was withdrawn but it can still be purchased on techstreet. The other type of contactor is referred to as a causes the water that was absorbed in the contactor to packed tower.
