Recovery of heat of reaction in batch processes in a Dutch company
In continuous processes, the recovery of heat of reaction can easily be made part of the plant's heat
integration set-up. In batch processes this not the case, because the heat-in and heat-out flows do not occur
at the same time. Batch processes generally have a sequence of heating up (starting the reaction) and
subsequently cooling down (removing the heat of reaction and maintaining the required reaction
temperature).
In some batch processes, the heat of reaction can be quite high e.g. in ethoxylation reactions. A solution
might be the installing of heat buffer systems. This is, in principle, a rather simple technique, but it is quite
difficult to make it work under practical production conditions.

BEST PRACTICE Cover-note
TITLE: Best practices in Compressed Air production for process, instrument and general utility uses
SUMMARY OF BEST PRACTICE
In the design and operation of compressed air systems a number of guidelines must be followed to ensure an energy
efficient operation. These rules address the choice of compressors, additional apparatus, the lay-out of the system and
the control system as well as the type of use of compressed air and the systems maintenance.
KEY ISSUES TO CONSIDER
The age of a system is an important issue.
Since process installations are generally updated, changed, debottlenecked etc. over time an older system is more likely
not to have a good match with the compressed air demand .
The choice of whether or not to use compressed air for certain application and of what quality also has a great influence
on costs (compressed air is an expensive broom)
Regular maintenance and inspection is vital ! Air leakages may run up to 20-30 % of air production, causing an 20-30 %
higher electricity use
DOs and DON’Ts
Regular inspect the system for air leakages. A 20 % loss in a 30 m3/min system will cost you approx. €25.000 /year
Be sure to select the right air quality for the right uses.
Be sure of the right compressors configuration and flow control (the optimum combination of off/on and frequency
control)
Avoid high pressure drops in the system. 1 bar overpressure in a 10 bar system will result in a increase in electricity use of
approx. 8 %
Approx. 90 % of the energy used is converted into heath, around 65 % of this heath can be recovered and used for heating
purposes
Choose the air inlet point with the lowest possible temperature (1 % energy savings/3 degrees lower temperature) but
avoid dirty or wet conditions.
