But whereas coming to a Condenser its main duty is Condensation, so whenever the condensers condensers some vapour's then its duty is over.
Condensers were of many types, shell and tube, double pipe, plate and frame, scrapper type, longitudinal extended surfaces, so being frank we can use a Heat Exchanger as a condenser, but we cant guarantee the efficiency, which is basically depends.

As nouns the difference between condensate and condensation is that condensate is (physics) a liquid that is the product of condensation of a gas while condensation is the act or process of condensing or of being condensed; the state of being condensed.
As a verb condensate is to condense. As a adjective condensate is (obsolete) made dense. Condensation in a vertical tube bundle passive condenser – Part 1: Through flow condensation. International Journal of Heat and Mass Transfer53 (), This up-to-date reference covers the thermal design, operation and maintenance of the three major components in industrial heating and air conditioning systems including fossil fuel-fired boilers, waste heat boilers and air conditioning evaporators.
Among the distinguishing features covered are: the numerous types of components in use and the features and relative merits of each, overviews of Reviews: 2. In either design, the condensed vapor forms a film on the cooled surface and drains away to a collection tank for storage, reuse, or disposal.
In contrast to surface condensers where the coolant does not contact either the vapors or the condensate, contact condensers cool the vapor stream by spraying either a liquid at ambient. CONDENSER DESIGN CASE STUDY: Evaporative condenser is considered for.

With a self-explanatory name, Condenser Design is a powerful piece of software designed to help you perform complex thermal analysis on shell and tube condensers. Put simply, Condenser Design. Direct-contact condenser: The condenser receives kg/s of steam and water with a quality of from the turbine at a pressure of MPa.
It mixes with kg/s of cooling water (CW) at 27°C. The condensate leaves the condenser as a subcooled liquid to be pumped to the water cooling tower. Request PDF | Condensation | The article contains sections titled: uctionDefinitionHistoryClassificationVapor–Liquid ContactEquipment.
The findings show that augmenting the rate of condensation by varying the condenser design increases the still yield to a limit and then decreases this yield at a higher condensation rate.
CSS has the smallest freshwater yield and still with PHS has the maximum production with an increment of 54 % comparing with GC condenser. Marangoni condensation is formed due to the surface tension gradient caused by the local temperature or concentration gradient on the condensate surface; thus, the investigation of the surface temperature distribution characteristics is crucial to reveal the condensation mechanism and heat transfer characteristics.
Few studies have been conducted on the temperature distribution of the. tubes to provide a steam velocity in the range between () and (7) m/s. The condenser entering air dry bulb temperature was ranged between (21) and (42) o.
Cand condensation load capacity fell in the range of (11) and () kW. The air flow rate was () cfm and () cfm corresponding air face velocities of (3 and 6) m/s.
Compact heat exchangers are being increasingly considered for condensation applications in the process, cryogenic, aerospace, power and refrigeration industries. In this paper, different configurations available for condensation applications are analyzed and the current state-of-the-knowledge for the design of compact condensers is evaluated.

Main Condenser – Steam Condenser. The main steam condenser (MC) system is designed to condense and deaerate the exhaust steam from the main turbine and provide a heat sink for the turbine bypass system.
The exhausted steam from the LP turbines is condensed by passing over tubes containing water from the cooling system. If you lack background study, obtain a copy of Kern's classic book, "Process Heat Transfer" and study it carefully.
In it you will find the method used to process design an overheads condenser. For a typical explanation of how condensation is treated in process heat transfer design, read and study the attached document.
This may help orient you. Condenser, device for reducing a gas or vapour to a sers are employed in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and fluorinated hydrocarbons.
The petroleum and chemical industries employ condensers for the condensation of hydrocarbons and other chemical vapours. Download Condenser Design for Windows to perform thermal design calculations for shell and tube condensers.
Condenser Design has had 1 update within the past 6 months. Flow regimes were observed visually at the inlet and outlet of the test condenser as the heat transfer data were collected. Stratified, wavy, wavy annular, annular, annular mist, and slug flows were observed. True mist flow without a stable wall film was not observed during condensation tests.
(See also Condensation and Condensers.) The essential objective in surface condenser design is to provide equal access of vapor to all the surface. Early attempts to provide overall heat transfer coefficients for the design of steam condensers took no account of.
General principles. Designing and maintaining systems and processes using condensers requires that the heat of the entering vapor never overwhelm the ability of the chosen condenser and cooling mechanism; as well, the thermal gradients and material flows established are critical aspects, and as processes scale from laboratory to pilot plant and beyond, the design of condenser systems.
Shell And Tube Condenser Design - posted in Student: I am a third year student of chemical engineering. I am trying to design a shell and tube condenser for the purpose of reducing the amount of water in the waste gases coming from two furnaces.
The non-condensables gases will then be transferred into the NOx abatement. Can anyone help me with this design using excel spreads hit. Condenser Heat Exchanger is very common in process industry, condensers may be classified in two main types; Condensers which have a coolant and a condensing vapor brought into direct contact and other types which have the coolant and a condensate stream separated by a tube wall or a solid surface.
This Software deals with the type where the streams are separated when condensation occurs. A base condenser model was arbitrarily chosen and design conditions were established at 95° F.
The operating parameters of condenser subcool and air face velocity were examined over a wide range of ambient conditions to determine their effects on the seasonal COP. It was determined that there is a range of subcools and face velocities. The type of condensate formed affects condenser design.
Furthermore, the type of condensate formed determines the type of vapor-liquid equilibrium calcula-tions used. If condensates are miscible, whether ideally or nonideally, the con-densate should remain in intimate con. The books that I looked through only have information about design procedures of total condensers or reflux condensers.

In systems involving heat transfer, a condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling.
In so doing, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many industrial systems.
Condensers can be made according to numerous designs, and come in many. Condensers are often used in reflux, where the hot solvent vapors of a liquid being heated are cooled and allowed to drip back.
 This reduces the loss of solvent allowing the mixture to be heated for extended periods. Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection. For fractional distillation, an air or Vigreux condenser is.Condensers can be designed in several styles to meet the process needs, and footprint available.
Reflux condensers can be designed to mount right on to a reactor’s vent flange. Vapors rising up through the tubes of the condenser are cooled by the cold medium in the shell, and the condensate then drips back down into the reactor.If air were free of tiny particles, called aerosols, condensation would only occur when the air was extremely supersaturated with water vapour.
In the atmosphere, however, there is an abundant supply of aerosols, which serve as nuclei, called condensation nuclei, on which water vapour may are hygroscopic (moisture-attracting), and condensation begins on them when the .
