The RJ-V1 valve is a general purpose moveable float valve unit used in various services. The valve lid is normally 1.5 mm thick from which three restrictive legs are formed integrally. Various valve lifts are possible according to the leg rise. To improve the valve activity in certain cases trays are equipped with light and heavy ...

The RJ-V4 valve is a low pressure drop general purpose unit in that the tray deck consists of a venturi-shaped orifice rather than a sharp-edge orifice. The venturi opening reduces significantly the pressure drop of the vapour at the deck entry and vertical curtain area. This leads to greater flexibility at lower vapour rates compared to that with a sharp-edge orifice. The RJ-V1 is used as the ...

The RJ-VO valve is a fixed unit punched out of the tray deck at a fixed vertical curtain distance. The valve consists of 6 legs formed integrally with the tray deck. The fixed nature of the valve unit implies an operating range flexibility similar to that for sieve trays. The main advantage of fixed valves is that the high horizontal vapour velocity issuing through the narrow curtain area ...

Conventional trays are cross flow trays. Liquid descending from the tray above emerges from the inlet down comer and flows across a rapidly diverging/converging open channel or tray active area to the outlet down comer. Vapour from the tray below is forced through the active area into the cross flowing liquid to produce a two-phase mixture of aerated liquid. The nature of the aerated liquid is ...

Bubble cap trays were the work horse tower internal in the first part of the twentieth century until the late 1950's when it was superseded by sieve and valve trays. It consists of a flat perforated deck in which the holes are enclosed with vapour or gas chimney risers and caps in the form of inverted cups mounted on top of the risers. The caps can either be equipped with slots or holes, through ...

These two tray types are located inside a column in such a manor that the liquid and vapour are brought in to direct contact by forcing vapour through falling liquid. Liquid descends from one tray to the next either as a curtain of liquid raining down or as liquid rivulets passing through holes in the tray deck. Tray panels are flat or slightly inclined decks that occupy 40-60 % of the column ...

Raschig USA prepared the mechanical and process designs of the trays for this tower and then supeivised the fabrication and assembly of the several trays required for the tower. The design included all aspects of the tray seen here -including the support arms in addition to the panel itself. Also please note manways included in the tray design on either side of the pressure relief ...

Like sieve trays, valve trays have been in use as far back as the 1950's but nowadays have become the more popular choice because of their greater operating range properties. Valve trays are essentially flat perforated trays with moveable or fixed valve units with or without a cage structure covering the holes. Moveable valves are disk-shaped type devices which are enclosed within a cage ...

The RJ-SVG valve is a fixed unit punched out of the tray deck at a fixed vertical curtain distance. The valve consists of 2 legs formed integrally with the tray deck. The fixed nature of the valve unit implies an operating range flexibility similar to that for sieve trays. The main advantage of fixed valves is that the high horizontal vapour velocity issuing through the narrow curtain area ...

Sieve trays became a dominate tower internal for mass transfer columns in the 1950's owing to their simple shape and ease of manufacture. This made sieve trays a popular device for extensive research and as a result, a considerable amount of experience has been gained for tray design and it's application. Sieve trays are flat perforated plates in which vapour is forced through the holes into the ...

The RJ-A3 is a two-piece valve unit to maximize vapour rate flexibility. It comprises of a moveable light weight valve disk which is enclosed in an open orifice cage structure with four legs that are attached firmly to the tray floor. Dependant upon the vapour rate, the valve disk moves up or down within the cage structure and the maximum opening is controlled by the height of the cage legs. The ...
