Process Condensers - Overview

Shail Vac has developed a unique perfection in designing and manufacturing of Process Condensers since more than over one and half decade. The highly experienced team of Shail Vac contributes significantly to ensure that our customers enjoy the best in class experience during our services. Our Quality Control personnel ensure that all the products are manufactured from a QA certified raw materials which have undergone vigorous testing and stringent QC norms.

CONDENSER is an apparatus used to reduce a vapour to its liquid state by removal of latent heat from the vapour. Its major function is to reduce the load of condensable vapour going in to the succeeding stages of ejectors.

 
There are mainly two types of condensers :
Direct contact condensers   Shell and tube type (Surface) condenser
 
Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors Direct contact condensers
  • A direct contact condenser is an inexpensive way to condense motive steam in a steam jet vacuum systems.
  • This type of condenser could be made with non-corrosive materials that could be used in a corrosive operation.
  • The condenser has no moving parts, so it requires virtually no maintenance.
  • This type of Condenser mixes the condensing vapours and water intimately, thus causing condensation.
  • Due to pollution caused by direct mixing, these Condensers are now used only for applications in which vapours are clean and where initial cost is a primary factor.
Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors Shell and tube (Surface) condenser
  • These Condensers do not mix vapours and cooling water, so there is no contamination of the cooling water.
  • A shell and tube heat exchanger-specially adapted for condensing on either the shell or tube side is often used for pre, inter or after-condensing.
  • If the condensing vapours are extremely fouling, tube-side condensation is preferred for easy mechanical cleaning.
  • If fouling is minor, shell-side condensing is better because of higher condensing efficiency. Shell and tube condensers can be either fixed tube sheet or removable tube bundle design.
  • The removable tube design simplifies cleaning both sides. Units are available in any combination of materials to suit process applications.
 
Theory :  

Condenser may be divided in more four types according to their use or says their position in vacuum system.

Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors Pre-Condenser:

It is used for direct condensing of vapours from the process. Non-condensable are removed from the pre-condenser by one or more ejector stages. The absolute force of process must be adequately high to allow condensation with the available water supply.

Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors Inter-condenser :
Inter-condenser is used between the ejector stages where two or more stages are required to compress non-condensable from a process or condenser pressure to atmospheric pressure, also it eliminates the handling of motive steam from a preceding stage.
Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors Condenser or booster condenser :
They are Used to condense process vapour and motive steam form one or more preceding booster ejectors which compress process vapours from required low absolute pressure to the higher absolute pressure necessary for condensation by the available condenser water.
Direct Contact Condenser, Shell and tube type condenser, Surface condenser, After condenser, Inter condenser, Pre condenser, Booster condenser, Reduces vapour  and condensable loads, Barometric height installation, Ground level installation, Cooling tower, Shell atype condenser, steam jet vacuum systems, condenser,  booster ejectors After condenser :
After condenser is used to condense steam discharging from A to Z or last stage ejector at atmospheric pressure. Non-condensable are vented into atmosphere.
