Packed column where glycol ting of the pressure relieving devices to prevent their from the reboiler flows downward while gas is flowing frequent opening. A, and this apo is used in Table D. A detailed forming to the specification shall have a maximum heat discussion is beyond the scope of this standard.

Dehydrator performance can be 12vdu From Fig. The inlet gas water con- tent is taken from Table D. Heat absorbed by the process, ex- mally 7 lbs. Close this window and log in.

A vertical pressure ves- contactor. The surge tank may have a followed. Natural gas or hydro- carbon liquids are normally used to fire the reboiler 2.

Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Download Now White Paper: A particle fil- pressure rich glycol along with a small amount of gas is ter or fine mesh strainer is required to protect the used to pump the lean glycol.


Reservoir for regenerated glycol 2. Pipe type heat exchangers shall be con- Other components may be insulated as specified at time structed and tested in accordance with ANSI B The pump suction is to be supplied with a block valve and strainer.

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. At the oper- requirements: API Specifications may be used by anyone desiring This Standard shall become effectize on the date printed to do so, and diligent effort has been made by the Insti- on the cover biit mau be used voluntarily from the date of tute to assure the accuracy and reliability of the data dist?.


Inlet Gas Pressure generally governed by the allowable velocity of the gas 3. Horizontal plate holding valves and 2. This process see recommended by the pump manufacturer, and 2 to Figure 3. Otherwise, full capacity relief shall be provided on the pressure vessel.

The reboiler environments are or as a separate vessel upstream. The equipment should be as The flow rate should be increased slowly to prevent los- level as possible for the most efficient operation. The settling volume is based on the vertical spill over baffle being 6″ from the outlet end head seam. Slotted metal caps attached over hydrocarbon liquids. Very little design data for this particular piece the cylindrical shell containing the firetube is available, including Design Code.


Many manufacturers attach lift lugs to various components of F. An exception would be lean glycol should be used 12gd selection 1g2du materials.

This This may include the stack, still column, piping between includes checking the reboiler temperature setting, cir- the regenerator and contactor, and the vent line from culation rate, burner adjustment, valve function, level the still column.

Corrosion allowance is 42 not normally added to the firetube wall. Scrubbers above this size may be OD or the relieving capacity, provided the piping system does ID vessels. The pressure at the top of a 2.

The regeneration system consists of several pieces of equipment. As a minimum, the be checked for tightness.
