Topic: TECHNOLOGIES FOR ENERGY RECOVERY SYSTEM

In this lecture we want to examine an important issue for sustainability: energy recovery system.

Marsina has developed technologies in order to match the most modern requirements in terms of energy saving and environmental pollutants limitation, both for the spray drying and the sulphonation plants. Concerning the former, a system has been developed in order to recover the residual energy contained in the exhaust air leaving the spray drying tower, which will be used to preheat the drying air fed to the spray drying tower, therefore reducing the total net need of heat required to produce drying hot air necessary for drying of detergent base powder.

Regarding the latter, Marsina has developed a proprietary technology for energy recovery from sulphur combustion to produce medium pressure steam, which will be used for main needs of the sulphonation process, such as sulphur melting (after

pressure reduction), combustion air heating, etc. So, how is this a benefit to our clients? First of all, energy recovery is a way to save

money: there are often initial costs involved in the implementation of energy efficiency projects, but in the long term, being able to monitor and reduce energy consumption will mean more money is available to invest back into other areas. And it’s also good for planet: global concerns about climate change have increased in

recent years, and fuels combustion and energy consumption remain the predominant causes of it.
