Hey Mr. Anonymous, if you are having two condensers, then go with chilled water for primary and chilled brine for secondary, and if you are able to maintain the vapour temperature above 15 deg C under vacuum, then go with degC Brine or 5 degC chilled water, if the temperature below 15 degC then use chilled brine at degC, and in case of the vacuum distillation, remember to have a equalisation line from secondary condenser to collection receiver, if the distillation is an atmospheric one, directly go with RT water at below 30 degC.

Can you explain theoretically and calculate and tell how to select utility as per the above post. Hello sir, I am chemical engineering student I am doing my final year project on extraction of oil from slurry in oil refineries.

Thats a good one, and i too tried that during my project but finally got diverted, Give your best good luck, and regarding extraction any possible help i'll do, mail me pharmacalc gmail. Please tell me how to do piping? How to design pipeline Header and Tappings from it? Mostly there wont be anything like a Propeller, may be i've mentioned above that's just for understanding purpose, because Propeller is what you see in a table fan, and the agitator that was usually called as propeller in pharma industry is strictly called as Retreat curve agitator, Coming to your question, Impeller is nothing but an agitator, and for example if an retreat curve is having two agitators then it is said to have 2 impellers.

That's it. That's it!!!! Hi, Great site, and great work. We are a 30 year old manufacturing firm specializing in chemical and pharmaceutical reactors. We are currently looking for professionals who can independently design agitators for the process and mechanical aspect. If you know any such individuals, please ask them to reach out to me at anuj thermotechengg.

Cheers Anuj. Great site sir I have ever seen Definitely I will mail ot post my queries Parth Panja Kolkata. Thanks and you can feel free to comment your queries.Lead times may vary.

Anchor-type agitators Anchor-type agitators are principally designed to mix highly viscous products and non-Newtonian fluids, i.Liquid flow in the impeller swept region of vessels with a turbine-type agitator was examined for the flow path between the neighboring blades of the rotating impeller. Visualization of the flow and its measurement were done using particle tracking velocimetry with a camera rotating along with the impeller.

Internal liquid flow of the impeller differed when the velocity magnitudes were compared in conditions with and without baffles. Larger circumferential and radial velocities were observed without the baffles and with the baffles, respectively, which was considered to result in the difference of impeller power transmission. Efficiencies produced, based on the flow-head concept, reflected the impeller power characteristics.

The turbine-type impeller as an actuator was demonstrated to improve in the flow characteristics with viscous losses increased by the baffles. In terms of impeller efficiencies based on the power consumption, the effect of baffles for the energy was as a decreased transmission and an increased transport. Vessels that are agitated by mechanically rotating impellers are commonly used in industrial applications of chemical processes.

When low-viscosity liquids are treated, baffled vessels having a disk turbine impeller with six flat blades are often employed. For such a configuration of the apparatus, knowledge related to the liquid flow within the vessel has been accumulated for utilization in operational and geometrical design Lee and Yianneskis, Lee, K.

AIChE J. Dynamics of the bulk flow produced by the turbine-type impeller within the vessel were documented by a number of researchers Yianneskis et al. Fluid Mech. Additionally, the characteristics of the liquid flow were elucidated for the region in the vicinity of the impeller, which is essential in the apparatus Sharp and Adrian, Sharp, K.

Most of these works confined the observational region to that outside the rotating impeller. Fewer works have examined the liquid flow in the impeller swept region, which is defined as the region swept by the rotating impeller: the region between the neighboring blades of the rotating impeller. Examination of such an internal flow of the impeller as surveyed below enables consideration of the energy conversion upon contact with the impeller blades between the agitator shaft and liquid within the vessel.

This provides a guideline for modification and design of blade geometries when the conventional design of the impeller requires improved performance, such as an energy-saving turbine agitator Rao and Sivashanmugam, Rao, D. A survey of earlier studies was made, with emphasis on investigations of the liquid flow in the impeller-swept region of vessels with agitators. Gray Gray, J. Uhl, V. By means of that relation, the discharge flow rate was calculated for different designs of impellers.July 8, An agitator is a device which is used to import motion in the form of stirring to the liquids or semi solids.

The shaft is connected to the gear box kato crane price the assembly is driven by motors using electricity. The purpose of agitators can be for mixing liquids, solids, slurries, pastes, mixing liquids and gases, mixing solids and gases, promote chemical reactions, promote heat transfer, etc. An agitator is installed in the vessel to ensure that the contents in the vessel become uniform and homogeneous and remain in a proper mixed state.

Since they have such wide variety of uses, the agitators are used in a multitude of industries such as chemical, process, food, pharmaceuticals, cosmetics, metal extractions, ink, paint etc. Agitators are used in a variety of industrial processes such as for carrying out a chemical reaction, for mixing operations, for filtration, for drying, for heat exchange, etc. The agitators are able to cater to such wide variety of applications because there are a variety of impellers which come in different shapes and sizes.

These agitators have an axial input and the output is radial. Turbine agitators are very versatile; they are able to handle a wide variety of mixing operations because these agitators can create turbulent movement of the fluid due to the combination of rotational as well as centrifugal motion. They are popularly used in metal extraction industries and also for chemical reactions and have a very high blending efficiency.

These are mostly used in chemical, pharmaceuticals, grease, cosmetics industries. It is one of the most basic types of agitator. It contains blades which are paddle shaped; the blades stretch throughout the vessel and reach the walls of the vessel. They are primarily used in applications where a uniform laminar flow of the liquids and little shearing is desired.

This type of agitator is especially used for viscous materials. These are mostly used in food, chemicals, pharmaceuticals, sorbitol etc industries. As the name indicates the shape of the impeller resembles that of the anchor. These agitators also extend and spread throughout the vessel such that there is very less clearance between the blades and the walls of the vessel.

Types Of Stirrer In Reactor Pdf

These agitators are also used when laminar flow conditions are desirable. These impellers sweep the whole batch because the blades are almost in physical contact with the walls of the vessels. These agitators are used in ink, paint and adhesive industries. These have impellers that similar to marine type propellers. They have blades which taper towards the shaft to minimize centrifugal force and to promote axial flow.

It means when this agitator operates the motion of fluid is such that the inlet flow is parallel to the shaft and the outlet flow is also parallel to the shaft, the ideal flow is axial in nature.

They are primarily used in applications to stir low viscosity liquids. The blades of the helical agitators are arranged in a structure of helix.

The appearance is similar to how a threaded screw looks. The motion of the liquids in this type of agitator is also axial in nature due to the way the blades or the ribbons move while helical agitator is in operation. There is a vigorous motion of the fluids within the vessel when the agitator is in operation.

It is used in polymer industries and other industries which require the use of quite viscous materials. September 7, August 27, Paddle Agitator.
