Introduction



In the majority of glass plant installations, vessels find universal application as Stirring vessels, reboilers, receivers and separators as well as for storage, feed or measuring. This section of the catalogue describes a wide range of both glass and non-glass vessels together with the items which are normally used in conjunction with them such as vessel covers and stirrers.

Standard glass vessels are available in two basic forms: spherical (available up to 200 litres in capacity) and cylindrical (available up to 200 litres in capacity). Large spherical vessels are not available but cylindrical vessels with higher capacity than 200 litres can be supplied to special orders.

All glass vessels have standard flat buttress end connections. Further details of these are provided in section Technical Information.

When spherical vessels are used as Stirring vessels or reboilers, the top branch in generally used for the column or stirrer. The side branches on standard vessels are generally DN 25, DN 40 or DN 100; DN 25 and DN 40 being at 10░ to the vertical (45░ on type VSU) and DN 100 being at 45░. The only exception to this are type VSD spherical vessels which have DN 50, DN 80 and DN 150 side branches at 90░ to the vertical and are used mainly in boiler circulatory systems. The smaller branches are normally used for such components as thermometer pockets, resistance thermometer and feed pipes. The DN 100 branches are normally used for charging solids or for the connection of vapour pipes when the top branch is used for a stirrer.

In application where temperature control is necessary, heating bath and mantles are available and detailed in this section. In addition, some glass vessels are available with jacket for close temperature control. If spherical or cylindrical vessels are used in conjunction with a heating mantle or bath, a longer bottom outlet is required and should be specified when ordering. The VSL spherical vessels are specifically designed for this purpose.

The majority of vessels have DN 40 bottom outlet. For application where it is necessary to avoid the build-up of solids in this outlet, the vessel can be fitted with a bottom outlet valve. (See section – Valves & Filters). This should be specified when ordering. The type RFC valve is an ideal alternative for vessels, which do not have a sealed-in valve seat.

By combining vessels with stirrers and stirrer drives, an extremely wide range of agitated Stirring equipment options is possible. This fact is enhanced by the inclusion of  PTFE Stirrers as well as their glass counterparts, thus allowing further options to be considered in the process design. Vessel/stirrer compatibility tables are detailed in individual stirrer description.

Both spherical & cylindrical vessels can be supplied with graduations to special order. Standard graduated cylindrical vessels are shown in this section.

For standard flat buttress end connections from DN25 to DN150, it is possible to achieve a 3 deflection in the joint by using a flexible gasket. Details of these and all other couplings and gasket can be found in section Couplings.

Unless otherwise stated, all dimensions are given in mm. All vessel capacities are given in liters.

For permissible operating conditions, unless otherwise stated in the individual description,  please see section Technical Information.

They can be used under full vacuum. The table above shows the maximum working pressure which we recommend for each size.

The nominal capacity is in liters.

Vessels with catalog reference suffixed "L' have longer bottom outlets, DN1, for use with heating mantles and heating baths.

Cylindrical vessels can be used for a wide variety of purposes; for example, Stirring vessels, separator vessels, receivers or feed vessels.

Note :

Cylindrical vessels up to a capacity of 50 liters can generally supported by the upper flange. Vessels of 100 liters capacity and above must be supported from below in a vessel support.

Graduation:
All these cylindrical vessels can be graduated if required. When ordering please indicate the graduation required and add the letter G to the catalog reference (e.g. VZG 20/9 graduated in liters).

The nominal capacity is in liters.

This is a simple cylindrical steel tank with copper steam coils inside it. The drain plug is 1" N.P.T., and the two steam coil connections are 3/4" N.P.T.. A steel ring wrapped with TFE rope is provided to hold down the vessel and prevent it from floating.

Use vessels with either a 25 mm or 40 mm diameter neck at the bottom-150 mm long; please specify which diameter ordering the heating bath tank. The bottom neck of the vessel is sealed through the tank with a rubber gasket.

Another method of heating and cooling vessels is to use a coil-type immersion heat exchanger.

Heating baths can be used to advantage in applications where the material being handled would tend to block or stick to the coils type heat exchangers. The stuffing box for the bottom outlet is specially designed to avoid imposing any stress on the spherical vessel.

Although the standard heating baths are specifically designed for spherical vessels, similar baths for cylindrical vessels can also be supplied to special order. All these heating baths can be fitted with suitable temperature control equipment if required.
 

Note: Heating baths can only be used with vessels having a long bottom outlet, for example type L or vessels with sealed-in seat for bottom outlet valve BAL 1.5

      DN1 is the bottom outlet of the spherical vessel.
C is the PCD of the three support points.

Heating mantles provide a positive alternative to steam heating using boilers or immersion heaters. They run at black heat, transferring the heat to the liquid partly by radiation and partly by convection.

The heating elements are closely pitched in a sinusoidal pattern to give an even distribution of heat and to avoid hot spots. This results in a thermal efficiency exceeding 80%.

Precise control of heat input is provided by a system of energy regulators and switches built into the heating mantle circuitry. All heating mantles are fitted with safety cutout thermostats in order to prevent overheating of the glass vessel.

Type VSL spherical vessels – vessels with sealed-in valve seat for BAL bottom outlet valves are ideal for use with these units.

These mantles are flame proof and have been specifically designed for use in hazardous areas and include switches and control geared house in N.K.J, C.M.R.I. certificate No.CMRI/TC/h-954 date- 8.9.95, temperature classification: T1, group: IIA, and IIB.

Heating elements is flameproof by covering it in magnesium oxide powder and anti corrosive metal INCOLOY 800 tube. The heating element sheath is earth through junction box so that no sparking or short circuit is possible, even in the event of spillage. Metal sheathed heating element produced uniform and black heat. Fiberglass cloth is used to cover the heating element, ceramic insulating blanket, refractory insulator, glass wool etc. used for insulation purpose.

The ring is fitted with a close fitting silicone correct rubber section and has three drilled lugs which correspond with holes in the appropriate support frame. The ring is positioned on three lengths of threaded rod on which it can be adjusted to the correct height.

These holders are used with the larger sizes of spherical vessels. They consist of a metal casing with a felt lining. The lining is shaped to fit the outside of the vessel. The holder is supported on three jacking bolts which are positioned in holes on a support frame. The bolts can be adjusted until the vessel is level and at the right height.

Horizontal Phase Separators

Horizontal phase separators are used to continuously separate immiscible liquids of differing specific gravities. These vessels provide for low velocities, long residence times and large interface areas between the light and heavy phases - all factors aiding the separation process. The two phases are independently drained off at the outlet end. The transparency of borosilicate glass allows visual inspection of the interface for ease of operation.

Cyclones

These cyclones are designed for the separation not only of droplets from gases and vapors but also of particulate solids from gases. The overall degree of separation can be as high as 99%, but this figure is governed to a large extent by the following factors:

The following are examples of limiting droplet diameters for the standard air/water system (at ambient temperature) with a velocity in the dip pipe of 15 m/sec:

The pressure drop in these cases is in the region of 250 to 300 mm water gauge.

The complete cyclone consists of:
1 glass body
1 dip pipe
1 coupling with gasket
