What are the operations that can be carried in a reactor The main operation is reaction, apart from that it can be used for extraction, concentration, crystallization and many more. What are the sub components of a reactor The notable sub components of a reactor are condenser, collection receiver, safety valve, rupture disc, etc. What is the main duty of a condenser The main duty of a condenser is to condense the vapour, to deliver exactly the main purpose is to remove the latent heat of vapour. ![]() Thats it. Now lets begin the calculation.

Step - 2: Calculate the maximum boil-up of the selected solvent. Step - 3: Calculate the Condenser Capacity for that boil-up. Thats it. your job is done. Now, lets begin, Step - 1: Solvent selection based on boiling point, Below is the list of solvent and their boiling points from my database. Step - 2: Boil-up calculation, This is somewhat crucial step in the whole process. To generate maximum boil-up the utility in reactor jacket shall be Saturated steam, Jacket pressure: 0.2 KgCm2. Temperature: 105.1 C, Refer Steam Tables A 10 KL SS reactor will have an Heat transfer area of 19.8 Sq.m, Use this Spreadsheet to calculate the HT Area - Learn it here Lets consider 70 occupancy, The effective HT area will be 13.86 Sq.m. The boil-up shall be calculated based on the formula: M x U x A x LMTD. ![]() Lets calculate, (M x Cp x dT) (M x ) (2954 x 0.22 x 5) (2954 x 85) 254340 KCal.

In the above post, ive considered the dead worst case, if the generated boil up can be condensed than automatically it can be useful for all solvent distillations.

As you have asked for comparison of lab vs plant, ive given you the relation.
