FREQUENTLY ASKED QUESTIONS

 

1.WHAT IS DNT ? 

DNT is in the business of providing an integrated solution of NOx controls for small to medium stationary combustion sources.  DNT's primary expertise is in urea based SNCR systems and dry urea handling systems.  To broaden out the offerings and to provide a single point of supply for related subsystems, DNT is also now offering on-site ammonia generation and SCR systems.

2.WHY  DNT ? 

Simply - DNT can provide a high quality installation at a lower cost.  DNT has a very efficient design and is not burdened with the competition's high overhead, licensing fees,  and mark-up.  The technologies are proven, and DNT has the experience to design, supply, build, and guarantee.

3. DOES DNT HAVE PATENTED TECHNOLOGIES ?

DNT's urea-based SNCR design is protected by Patent Applications.  DNT's is protected by Intellectual Properties Insurance - which can be extended to its customers.   DNT  warrants that it's Work does not infringe upon any intellectual property, will provide insurance to its customers as Additional Insured under DNT's Policy,  and will vigorously defend all claims of infringement.

4. WHAT GUARANTEES DOES DNT PROVIDE FOR IT'S SYSTEM?

DNT provides clear and enforceable guarantees.  See what the Other Guy is offering and then call DNT.  Our guarantee isn't vague. 

5. HOW CAN WE BE ASSURED THAT DNT CAN HANDLE OUR PROJECT ?

DNT has done it all before.  Potential customers are encouraged to contact DNT's references.  DNT does all of the process design, mechanical design, and Project Management.  DNT has partnership arrangements for Construction Management, Purchasing, shop fabrication, and electrical/controls.  For field work, DNT has field proven specs and contracts, as well as regional Installation Contractor affiliates to assure that the job gets done right the first time.

6. HOW MUCH DOES A DNT SYSTEM COST TO INSTALL?

NO ONE can design, supply and install a high performance SNCR system more cost effectively that DNT.  The installed cost is strongly dependant upon the complexity of the controls, and weakly dependant upon unit capacity. A typical automated installation using an existing CEM system should cost in the neighborhood of $5 per KW.  

7. HOW MUCH DOES A DNT SNCR SYSTEM COST TO OPERATE?

Chemical cost is the primary contributor to annual O&M costs.  Chemical  consumption is determined by the uncontrolled NOX generation rate, removal requirement, and boiler capacity/utilization. Purchasing liquid urea, and at moderate removal efficiencies, the operating cost is approximately $500 per ton of NOX removed.  Compare that to the 2005 NOx allowance market, which is currently over $3000 per ton.
