Packed Stripper Design Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream. Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream.separation processseparation process There are many different types of packing used and each one has advantages and disadvantages. There are many different types of packing used and each one has advantages and disadvantages. More common packing materials are metal and plastic Pall rings, metal Michael Bialecki rings, and ceramic Intalox saddles. More common packing materials are metal and plastic Pall rings, metal Michael Bialecki rings, and ceramic Intalox saddles.

Procedure: Procedure: - Estimate the slope m from equilibrium data of process. - Calculate the amount mGm/Lm, and y1/y2 to determine N OG from figure. - assuming 38mm and 1.5 ceramic intalox saddles. - calculate Flow of liquid vapor: - Design for pressure drop 125mmH2O/m packing and get K 4 from the figure. 125mmH2O/m packing and get K 4 from the figure.

Heat Exchangers Design Heat exchangers are the devises employed for transmitting heat from one fluid stream to another by indirect means. Heat exchangers are the devises employed for transmitting heat from one fluid stream to another by indirect means. there is a barrier which separates the fluids and permits heat to flow from the hotter to the colder stream without mixing of the streams. there is a barrier which separates the fluids and permits heat to flow from the hotter to the colder stream without mixing of the streams. Shell and tube heat exchanger in their various construction modification are probably the most widespread and commonly used basic heat exchanger configuration in the process industries.

Compressor Design A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Gas compressors are used in various applications: Gas compressors are used in various applications: in petroleum refineries, natural gas processing plants, petrochemical and chemical plants. in petroleum refineries, natural gas processing plants, petrochemical and chemical plants.

Procedure: Procedure: Polytropic exponent can be determined from the following equation: Get the work from the following equation: The horse power is calculated by multiplying the work by the molar flow rate:

Finally, we get the compressor efficiency: Where K = (Mw * Cp) / (Mw * Cp – 1.986) Depending on the horse power we can decided which type of compressor we going to use and calculate its cost.

Valve Design A valve is a device that regulates the flow of substances either gases, fluidized solids, slurries, or liquids) by opening, closing, or partially obstructing various passageways.
