Hopkins Rice SCR Catalyst Replacement

Project Description: 3.1 Scope
The city of Tallahassee owns and operates seven Wartsila engines (five 50SG engines and two 34SG engines) that use emissions control catalysts. The catalysts for the 50SG engines are in a HUG EM400 housing, while the catalysts for the 34SG engines are in an HUG EM196 housing. Over time, catalysts degrade and will need to be replaced. This bid is for new catalysts to replace the existing catalysts in the installed Wartsila emissions control systems. The specific types of catalysts being sought are listed below.
3.1 Catalyst Types
The three different catalysts used for emissions control of the Wartsila engines are described below.
a. SCR
Used for the catalytic reduction of nitrogen oxides. HUG RFV 1300.103.C5.00.S150.450.000 or equivalent.
b. ROM
Used for the catalytic reduction of nitrogen oxides while simultaneously suppressing higher ammonia concentrations.
HUG ROM 1300.103.C3.D1.S150.045.255 or equivalent.
c. OXI
Used for the catalytic oxidation of CO, VOCs and Formaldehyde. HUG OCT 1500.141.A7.00.S150.150.000 or equivalent.
