The method proceeds by calculating the heat capacity rates (i.e. mass flow rate multiplied by specific heat capacity) and for the hot and cold fluids respectively. To determine the maximum possible heat transfer rate in the heat exchanger, the minimum heat capacity rate must be used, denoted as C m i n {\displaystyle \ C_{\mathrm {min} }} :
A Dimroth condenser, also known as a spiral condenser, named after Otto Dimroth, is somewhat similar to the coil condenser; it has an internal double spiral through which coolant flows such that the coolant inlet and outlet are both at the top. [19] [20] The vapors travel through the jacket from bottom to top. Dimroth condensers are more ...
In a pot still, if the tube leading from the boiler to the condenser, the lyne arm, is angled upward, more liquid will have a chance to condense and flow back into the boiler leading to increased reflux. Typical results can increase production as high as 50% over the basic worm type condenser.
Pinch analysis is a methodology for minimising energy consumption of chemical processes by calculating thermodynamically feasible energy targets (or minimum energy consumption) and achieving them by optimising heat recovery systems, energy supply methods and process operating conditions.
A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid. The vapor typically enters the condenser at a ...
In thermodynamics, the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc.

Total absorption costing (TAC) is a method of Accounting cost which entails the full cost of manufacturing or providing a service. TAC includes not just the costs of materials and labour, but also of all manufacturing overheads (whether ‘fixed’ or ‘variable’).
