INCREASE REVENUE WITH LITTLE TO NO CAPITAL

The HHS Process offers a low-cost, highly profitable method of extracting greater value from customers’ existing product stream. Tailor-made operational agreements ensure that customers can generate new revenue and bolster plant efficiency with minimal capital outlay.  fine and ultrafine coal may comprise a smaller fraction of a processing facility’s product stream, but recovery of additional product goes straight to the bottom line..

IMPROVE PLANT ECONOMICS

The high quality specifications of HHS Process product may allow customers to raise the gravity in other processing plant circuits and improve the recovery of coarser coals.

EXTEND SLURRY-POND LIFE

Potentially recoverable coal in fine slurry typically represents 35% to 65% of the solids being pumped from the thickener to the waste impoundment. Recovering this coal as a saleable product will extend the life of the slurry pond and reduce the potential for a black water spill.
