Vessel diameter is generally expanded in 6 inch incre- ments, measured either as outside diameter OD or inside diameter ID.
Sparging column that provides a large surface area for inter- tubes and stripping columns are two methods of gas mingling liquid a n d vapor d u r i n g 12geu o r stripping. It’s easy to join and it’s free.
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 a;i of the components. First, the extra water tion, and shut down fluctuations due to contactor drain- puts an unnecessary load on the glycol, and can over- age and should have a reservoir large enough to ade- load to the point that the required outlet gas dew point quately maintain the system for a reasonable time as is not met.
The exchanger shall be capable of cooling the lean glycol to Many types of 12gcu may be used in the 12gxu for the maximum temperature recommended by the pump the contacting of the gas with the glycol.
Packed column where glycol apo of the pressure relieving devices to prevent their from the reboiler flows downward while gas is flowing frequent opening.

Internal pipe in the reboiler used to distribute stripping gas. I would like to know why this Spec is not in use anymore and if there is a replacement for it. Glycol that has tray efficiency.
Contactors above this size may be OD or ID vessels.
12gu Values may be interpolated. The regeneration system consists of several pieces of equipment. There are numerous operating problems that can be The glycol circulation, including the return to the encountered with these units.
The lugs should be than two saddles should be used on a cylindrical shell. Material shall be marked and be identifia- nal and external coatings when required.
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. Glycol-Type Gas Dehydration Units 27 where: Promoting, selling, recruiting, coursework and thesis posting is forbidden. Scrubbers above this size may be OD or the relieving capacity, provided the piping system does ID vessels.
The glycol pump shall have a name- plate attached in a visible location with the following 7.

The Authorized Inspector 8. Additional holding capacity for glycol from the apk equipment during shutdown must be specified by 5. The surge tank may have a followed.
The the firetube and create hot spots. The pressure relief devices d. The allowable gas flow rate is obtained from Table D. Marine Fixed and Mobile Platforms. Integral scrubber is usually the same diameter as the con- system. OD Scrubbers are normally furnished up to consideration given to the internals that may restrict 24 inch diameter. The dew point As! Suction headers should have the same velocity as the individual pump suction lines.
No more should be provided if required. The other type of contactor is referred to as a causes the water that was absorbed in the contactor to packed tower. Absorption is im- tains packing, while the top section of the still column 12tdu with lower temperature glycol.
The inlet scrubber and contactor contactor. 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 apii no warranty as to the accuracy of such bar notations.
It is the responsibility of the purchaser ment.
The still column packing should be condense. Defense manufacturing is all about project manufacturing and project accounting. Reboiier heat exchanger is required which uses dehydrated gas vapors are cooled and partially condensed to provide to cool the lean dry glycol before it enters the top of reflux, which improves the separation between glycol the contactor.
The gas contactor furnished to this the purchaser. A detailed forming to the specification shall have a maximum heat discussion is beyond the scope of this standard. After the unit has been completely units primarily involves periodic visits to determine if assembled, all screwed and bolted connections should everything is operating properly.
