Coal India subsidiary-Central Coalfields Ltd (CCL) has invited bids to set up New Rajrappa coking coal washery on build-own-operate concept.
The washery, with an annual capacity of processing 3 mnt of raw coal, is to be constructed within 36 months from the date of agreement signing. Thereafter, the bidder would be responsible for carrying-out operation and maintenance of the facility for an extended period of 18 years.
Indian coking coal, characterised with high ash content, requires beneficiation in the washeries to improve the quality post-which it can be blended with imported coal for steelmaking.
In fact, this would be the fifth coking coal washery of CCL. At present, the company operates four coking coal washeries with combined capacity of 9.35 mnt namely-Kathara (3 mnt), Rajrappa (3 mnt), Kedla (2.6 mnt) and Sawang (0.75 mnt).
Project outline
For the upcoming project, the operator has been provided freedom in selection of design and technology for the washery plant.
Raw coal for beneficiation would be supplied by CCL to the tune of 3 mnt annually. However, the plant is required to operate efficiently with an additional feed in excess of 20% over the throughput capacity.
This coal comprises average ash content of 25.1% on air dried basis (ADB), which can vary within the range of 24.8%-35.0%. The range of moisture content varies between 0.86%-4.89%.
The operator is required to supply processed coal with reduced ash content under two major product heads, namely-washed/clean coal and washed coal (power).
In case of washed/clean coal, the monthly average target for ash content is 18.0% (ADB) and total average moisture content must not exceed 9.0% (day-to-day basis). For washed coal (power), the target for ash content is 34% (ADB) and total average moisture content should not exceed 11.0% (day-to-day basis).
Bidding process
Bid evaluation would be carried out via reverse auction on the basis of washing charge quoted by the bidder in terms of per tonne of raw coal processed on ‘dry basis’.
These charges include cost for receiving and storage of raw coal, sizing/crushing, beneficiation, storage of products, delivery of products to the designated place, and handling of rejects.
The bidder with lowest bid (L-1) would emerge as the preferred bidder. In case, there are more than one L-1 bidders, the one having the highest net worth would be declared the preferred bidder.
The last date of bid submission is 25 July 2022.
