Met Coke Division (MCD) is primarily a backward integration initiative to support the pig iron operations, with 70% of the met coke output consumed internally in 2012-13. The Company commissioned 2 new batteries of the met coke during the year doubling the capacity to 560,000 Tones/Year.
SESA’s Energy Recovery Coke Making Technology is an environment-friendly technology that is characterized by low capital and operating cost, high energy recovery, capable of producing high quality metallurgical coke. This technology is available for license globally in standard modules of 0.3 MTPA with a potential to generate 21 MW of electrical energy. Developed through in-house efforts, SESA holds patents in US, India, Brazil and Europe for this technology. This patent is a reaffirmation of SESA’s commitment to development of innovative and cutting Edge solutions.
Vedanta’s Met coke Division, Manufacturing low ash Metallurgical coke by means of non-recovery heat recovery coke making process based on SESA’s patented technology.
Salient features of SESA’s coke technology are,
Metallurgical coke is the costlier and main raw material for steel industries and cupola furnaces. Main raw material for coke making is coking coals and it is being imported from different parts of world mainly from Australia, Russia, South Africa and Indonesia.
Metallurgical coke comprises of four different grades based on size of coke:
Vedanta’s Met coke Plant is strategically located at Amona, on the banks of Mandovi River, at an optimum distance of 40 kilometres from Marmagao port which gives us the dual advantage for transportation of raw material coking coal’s by riverine barges from different parts of World. Met coke division has two coke oven batteries of production capacity 0.522 Million tons per annum.
Vedanta’s Met coke Plant produces low ash, low Sulphur & low phosphorous Metallurgical coke which is suitable for blast furnaces and cupola furnaces which are mainly manufacturing automotive castings.
