Sugar Industry energy Audit

Sugar-making process involves several energy-intensive processes – cutting the sugarcane, crushing to extract juices, preparing the syrup, and finally producing the desired quality of sugar. Treatment of sugarcane juice to produce the final product requires heat that is supplied from steam at low pressure (around 1 kg/cm²).

Boilers in sugar mills are run using the bagasse which is the by-product of the cane crushing. Steam produced thus is used for the process as well as to generate electricity. Any surplus electricity beyond the in-house consumption can be sold to the grid. This makes the sugar industry a lucrative industry financially, and also gives it added focus on importance of energy efficiency.

Eco Energies can help sugar mills to reduce their energy bills by increasing energy efficiency of various processes and utilities. The following are some of the energy saving measures that can be implemented:

• Steam optimisation
• Bagasse dryer
• Installation of high tensile (HT) motors
• Possibilities for variable frequency drives (VFD)
• Replacement of inefficient pumps
• Flow Control Strategies
