Hopkins SCR Catalyst Replacement

Project Description: The City of Tallahassee owns and operates seven (7) Wartsila reciprocating engines, each equipped with its own emissions control system. Over time, the catalyst bricks within these systems degrade and require replacement. This request for bids is for the removal and installation of catalyst bricks for the Hopkins Generating Station and Substation 12 reciprocating engines.
Hopkins Generating Station operates five (5) Wartsila 18V50SG reciprocating engines, each with its own emissions system reactor vessel. Each reactor contains four (4) rows of catalyst bricks:
• Two (2) rows of NOx catalysts
• One (1) row of ROM catalysts
• One (1) row of oxidation catalysts
Substation 12 operates two (2) Wartsila 20V34SG reciprocating engines, also each with its own emissions system reactor vessel. These reactors also contain four (4) rows of catalyst bricks with the same configuration:
• Two (2) rows of NOx catalysts
• One (1) row of ROM catalysts
• One (1) row of oxidation catalysts
It is anticipated that catalyst brick replacement will be performed annually on one or more of the engines at either Hopkins Generating Station and/or Substation 12.
It is not the Owner's intent to specify all applicable codes and technical requirements related to the removal and installation of emissions control system catalyst bricks. Nor does this request attempt to define all requirements governed by existing codes and standards. The Bidder is responsible for providing a high-quality product that meets or exceeds all relevant codes and standards. The omission or deficiency of any item in this specification does not relieve the Bidder of that responsibility.
