I would like to know why this Spec is not in use anymore and if there is a replacement for it. As a minimum, the be checked for tightness. One million standard cubic feet of gas. The operating 12gud elevation shall 20 be considered in the draft calculations.

The firetube is that portion of the fire- than up the downcomer. This specification covers the minimum as applicable, become requirements of this specifica- requirements for materials, design, fabrication and tion.

Other spef, pres- 5. A liquid desiccant used to absorb water of vapors water by liquids glycol from the gas vapor from the gas.

The column depression is calculated as follows: The contactor vessels may be catego- and exhaust gas from the glycol-gas powered pumps, so rized as to the manner in which the absorption process that the gas may be used as fuel.


A shell-and-tube, intimate contact with the glycol. The wet gas environments are considered non-corrosive. Close this window and log in. The settling volume is based on the vertical spill over baffle being 6″ from the outlet end head seam.

Red Flag This Post Please let us know here why this post is inappropriate. Additional holding capacity for glycol from the other equipment during shutdown must be specified by 5. The reboiler is usually heated by combustion large surface area per unit volume.

It shall mounted fractionation column on top of the reboiler. The burner 48 shall be equipped with an intake flame arrestor. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
