Industry Visit Report
Place : Baramati Agro Limited, Indapur
Date : 20th Dec 2017
The MBA Energy and Environment batch of EE 2017-19 got an opportunity to visit Baramati Agro Limited, Indapur on 20th Dec 2017. Since the course curriculum incorporates subjects related to energy efficient systems and generation techniques, A visit to a cogeneration plant added a good knowledge. The visit started with a briefing about the safety procedures and a description of the process. Each student and faculties were given a set of safety glasses, helmet, and a mask. This was a part of their safety system. The power plant had incorporated the quality management system, and they adhere to the ISO 9001:2008 and ISO 22000:2005.
The entire process like any cogeneration plant is divided into various stages. The first step was a combination of manual and automatic steps. The sugarcane being unloaded with the help of the overhead crane and put into the crusher. The maximum capacity that could be crushed at one go was 10-10.5T, but the capacity reached was up to 8T. The total Crushing capacity of our plants is 12,000 MT cane per day. The further steps involved were the complete juice extraction and bagasse production. They produce power from Bagasse, which is used as fuel for steam generation in boilers (quantity 120 TPH.) The steam from the co-generation boiler is used by steam turbines to generate power. The pressure of the boiler was maintained at 87 bar and the temperature was maintained at 520degC.
We moved around the entire plant that and got acquainted to the entire process including the process control room. They used the ABB software that gave us a brief idea about present condition of the process. We understood that apart from the boiler, the steam heat exchanger and the 7-stage turbine helped in producing about 22MW of power. They transferred around 13-14 MW of power to the grid and rest was used up by their sugar mill. We were also given insights on their emission control process. They produce almost 150PPM emission particle from the chimney.
After being acquainted with the power generation unit we further proceeded to understand how sugar was produced. They used the crystallization method to produce sugar. The total production capacity of 200,000 MT of sugar per annum. The entire unit consisted of centrifuge system to remove the extra residue and concentrators to get sugar extracts. We also got to see the belt production units being used at the filling stage. The production rate specified was up to 100 MT per day. This was the final stage of sugar production where both the filling and packaging took place.
Our visit ended at their recreation centre where we were offered both fresh sugar cane juice and sandwiches. It was an amazing and educational visit. It gave us an idea about how systems could made more efficient and safe. It was a great learning experience and we look forward to many such experience.
