THE KCA CARBON CONVERTER
Carbon Fines Processing Equipment
A: There are two options for ash treatment.
Option 1: Direct Smelting
Option 2: Fine Grinding & Leaching
A: The installed Carbon Converter footprint with the feed system is approximately 7.5m x 7.5m. This includes space required for proper operation and maintenance access.
An additional 6m x 8m carbon preparation space is also recommended to facilitate daily operations.
A: Hot exhaust gases from the furnace are cooled and treated with two wet venturi scrubbers in series, which condense liquid mercury for periodic collection from their respective tanks. The exhaust exiting the second venturi then passes through a bed of sulfur impregnated carbon to capture any residual mercury vapor.
In some cases, it is possible that a minuscule amount of condensed mercury can be carried out with the cooling solution stream. If this is not acceptable, then filters can be installed on the solution outlet.
A: An electrical feed requirement capable of supporting a 100HP / 75KW maximum, and 40HP / 30KW continuous electrical load.
A burner requirement of 500,000 BTU/hr (125,000 kcal/hr), which can be powered by either natural gas, propane, or diesel.
A cooling/scrubber solution requirement of 20gal/min (4.6 m3/hr), which can be pregnant solution, barren solution, or raw water.
A: Operating costs can range from US$50,000 – US$100,000 per year, excluding labor costs. These costs depend in large part on the nature of the feed. KCA provides a more concise operating cost estimate upon evaluation of each operation’s carbon.
Generally, with clean carbon and long furnace runs, we expect minimal operator time will be required. Dirty carbon may cause more difficult materials handling which may result in higher labor costs.
KCA will help define these costs more accurately as information is received regarding your carbon.
A: Currently, there is one size unit, but multiple units can be provided to reach the desired throughput. The modular design of the Carbon Converter allows for efficient shipping and installation of multiple units at a central location. The size is convenient for a single person to operate one or multiple units.
A: Upon receipt of purchase order and down payment, KCA can be ready to ship from our shop in Reno, Nevada USA in approximately 16-20 weeks.
A: KCA will guarantee equipment performance for a period of 12 months after completion of commissioning. The equipment is warranted against component failure due to faulty equipment or construction. KCA will repair or replace components at KCA’s cost and responsibility during the 12 month warranty period. KCA will include one follow-up visit at no charge after commissioning, to assess the performance of the unit and perform repairs/adjustments if necessary.
