Sugar factories operate CHP; combined heat and power cogeneration systems that produce both steam and electricity. The plants use Bagasse to produce steam at high pressure in water tube boilers. This high pressure steam is then used to drive turbo-generators which generate electricity to power the sugar factory. Exhaust/extracted steam from the steam turbo-generators is utilized in a system of integrated equipment to process juice extracted from the sugarcane into sugar.
The RYK Group has been among the first to realize the tremendous potential of bagasse to help in reducing the power deficit, by supplying energy to the grid, thereby contributing to the bio-energy effort undertaken by the country.
Having generated electricity, the resultant lower pressure steam is then used many times over in the sugar production process in highly integrated and efficient evaporators. Bagasse when burned in quantity produces sufficient heat energy to supply all the needs of a typical sugar mill, with enough energy to spare. To this end, a secondary use for this waste product is in cogeneration, the use of a fuel source to provide both heat energy, used in the mill and the electricity which is typically sold on to the consumer through power grids.
The power produced through bagasse based co-generation plants substitutes the conventional thermal alternative and reduces greenhouse gas emissions. In Pakistan, interest in high-efficiency Bagasse based cogeneration started in 2008. High-efficiency Bagasse cogeneration are an attractive technology not only in terms of its potential to produce carbon neutral electricity but also helps reduce reliance on imported fuels as well as providing economic benefits to the national economy and the sugar sector.
Bagasse based cogeneration projects have led to substantial and repeated opportunities for local manufacturers and contractors. Boiler suppliers, switchgear and transformer manufacturers, civil contractors, mechanical contractors etc. have reaped the benefits of multiple assignments and installations. The thrust on distributed generation which helps control system losses and the ever increasing awareness for cutting greenhouse gas emissions necessitize the shift to high efficiency cogeneration systems.
The sugar production process requires considerable energy which has an impact on our carbon footprint. To reduce our footprint wherever possible we invest in improving our energy efficiency, on-site generation and lower carbon renewable sources.
Producing sugar requires considerable energy which has an impact on our carbon footprint. To reduce our footprint wherever possible we invest in improving our energy efficiency, on-site generation and lower carbon renewable sources. For example, combined heat and power (CHP) is the most efficient way of converting fuel to useful energy so we use it at all our factories.
At RYK Group the co-products (such as Bagasse, the fibrous residue resulting from the extraction of juice from sugar cane) are employed to fuel the CHP plants, which produces renewable heat and electricity. RYK Group has been among the first to realize the tremendous potential it had towards reducing the power deficit, by supplying to the grid, thereby contributing to the bio-energy effort undertaken by the country.
