VGPlus Trays

VGPlus are Sulzer Chemtech’s high per-formance chordal downcomer trays. They offerindustryprovenandFRIvalidatedad-vancedtraytechnologyfortoday’smarket.

VGPlustraytechnologyisthecombinationof enhanced tray deck design with high performance downcomers:

•The use of optimized valve layouts, re-directing and froth promoting devices enhances the vapor/liquid interaction on the tray deck.

•Improved downcomer technologies,such as sloped, truncated, stepped and multi-chordal downcomers, reduces downcomer flood and backup, while the tray deck area is maximized.

This combination of all above mentioned features provides maximum capacity and trayefficiency.

Bubble Cap Trays

Bubble Cap trays are used for low liquid loads and very high turn down ratios. Sul-zer offers a standard cap for 3” and 4”, and a slotted type for 6”.

Cartridge Trays

Cartridge trays are typically used for small columns where a tray man way is not fea-sible. Tower diameters range between 300 to 800 mm (12” to 30”). Cartridge trays are assembled in bundles for an easy and fast installation. They can be equipped with all types of tray decks and downcomers.

Baffle, Shower Deck, Disc & Donut Trays

These trays are arranged in a tower in such a way that the liquid flows down the column by splashing from one baffle to the next lower baffle, and the ascending vapor passes though the curtains of liquid spray. These trays are used in washing sections where fouling resistance has priority over performance.

Dual Flow Trays

Dual Flow trays are perforated trayswithout downcomers. They are typically equipped with large holes which make them particularly suitable for fouling ap-plications. However they provide limited mass transfer efficiency and have a nar-row operating range.

Slit Trays

The Slit Tray is a high efficiency devicewith circular symmetry, featuring rows of concentric slits for vapor passage. It ismainly used for the distillation of aqueous systems and specialty chemicals.

Main characteristics are:

•Lowtrayspacing:150–250mm (6” – 10”)

•High fractionation stages per given col-umn height

•Selfsupportingstructure

•Largeoperatingrangeupto1:4

•Suitablefor2liquidphasessystems

•Allow for any number of feed points orside draws

Liquid-Liquid Extraction Trays

Conventional extractor trays are designed withholespunched in the traydeck.Ex-tractor trays are equipped with enhanced downcomers and extruded holes which allow for:

•Higherfoulingresistance

•More uniform droplets, thus higher effi-ciency

•Wideroperatingrange

Self Balance Operating Mechanism

The unique orientation of the downcomers allows for an uniform liquid distribution on each compartment of the tray deck (blue arrows). The liquid flow path length are practically constant all over the sections.

The vapor is uniformly distributed underneath the tray deck and released laterally throughtheMVGvalvesperpendiculartotheliquidflow(redarrows).

Since there is no obstruction between the different compartments of the tray, both the liquid and vapor are naturally self balanced all over the tray for the most uniform mixing,contacting,andseparatingefficiency.

Shell HiFi Plus Trays

The Shell HiFi is a fractionation tray equipped with multiple envelope down-comers, oriented offset to the tray‘s center line.

ItconsistsofaHiFi trayequippedwithalayer of swirl tubes located underneath the tray deck.

Fields of Application

Shell ConSep trays have been used reli-ably in refinery, petrochemical, and gasplants for:

Debutanizer, Depropanizer, Deethanizer,C2&C3splitters,MainFractionators,andwherever the hydraulic loadings exceed the system limit of the column.

FRI Validation

Shell ConSep trays have been tested at FRI, in a 1.22 meter diameter tower, 2pass, with iso-butane / n-butane system at 11 bar.

At least 50 % additional capacity has been observed over other high performance trays,withaseparationefficiencyashighas 90 %. The capacity substantially ex-ceeded the system limit of the tower.

Operating Mechanism

Shell ConSep trays start to work when the conventional ones reach incipient flooding. The vapor, before reaching the next tray, passes through the swirl tubes where the entrained liquid is separated by means of centrifugal acceleration, is collected in the swirl tube deck, and is refluxed back to the downcomer below by means of a sec-ondary downcomer. Thus only clear vapor will rise up to the tray above.

Welding Free Tray Installation

Inseveralrevampprojectsaimedtoboosttheseparationstagesof an existing column, the number of actual trays must be in-creased i.e.

3-for-2, 4-for-3, or even 5-for-4.

To accomplish this target, a tailored mechanical design is required to avoid any impact on the schedule of the plant‘s turn-around, and minimize the costs.

Sulzer has developed a mechanical solution enabling installation of the trays by reusing the existing tower attachments, and with-out any direct welding to the tower wall, thus avoiding any post-welding heat treatment and/or hydraulic testing of the vessel. We have even been able to reduce consistently the turnaround time by using this technique.

The following devices may be used:

•Expansionrings

•Expansionjoints

•Verticalstruts

•Downcomeradaptors

•Solidorlatticebeams

The system can be used also for other purposes: modify the ge-ometry of existing downcomers; modify the number of passes; change the tray orientation; replace packing beds with trays.

Vibration Phenomena on Fractionation Trays

Insomecriticalapplicationsandunderspecificoperatingcondi-tions,vibrationphenomenamaybe induced to the trays. If thefrequency equals the natural frequency of the tray, the panels will crack and will be seriously damaged.

Based on plant feed-back data and in-house know-how, Sulzer has developed a design tool to check for the following two main parameters:

•Naturalfrequencyofthetraypanels,asafunctionofthegeom-etry, the supports, and the fabrication material type

• Vibration factor, as a function of the flow rates and physicalproperties of the streams being processed.

To prevent vibration damage a proper checking is required, and a
