Design-Build Services for
RICE NESHAP Compliance, Phase I and II HOMESTEAD, FL

RICE NESHAP Compliance, Phase I and II HOMESTEAD, FL; Poole & Kent Company of Florida

CLIENT OBJECTIVES

The City of Homestead’s objective was to update their facility in order to meet new RICE NESHAP (Reciprocal Internal Combustion Engine National Emission Standards for Hazardous Air Pollutants) requirements regulated under 40 CFR 63, subpart ZZZZ “National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocation Internal Combustion Engines.”

VALUE DELIVERED

Design and installation of new systems for retrofit power plant; compliance with RICE NESHAP requirements, minimal disruptions to facility operations; completed on schedule and within budget.

SCOPE OF SERVICES

In September 2012, Poole & Kent was awarded the contract for Phase I design, permitting, and construction for improvements to the three largest engines (one 8,800 kW unit and two 6,487 kW units) at the facility.

  • Combination silencer-catalyst units, where the oxidation catalyst equipment is located within a new silencer, to achieve a 90 percent reduction in carbon monoxide (final testing proved a 95 percent carbon monoxide reduction).
  • Monitoring equipment to record exhaust temperature and differential pressure across the catalyst
  • A filtered crankcase ventilation system meeting EPA rule compliance
  • Meeting 70 dB noise limitations at the property line
  • All required testing for Florida Department of Environmental Protection

Following the success of Phase I, in August 2013, P&K was awarded the contract for Phase II design, permitting, and construction for improvements to seven additional engines (all 2,070 kW units).

  • Combination silencer-catalyst units, where the oxidation catalyst equipment is located within a new silencer, to achieve a 70 percent reduction in carbon monoxide
  • Monitoring equipment to record exhaust temperature and differential pressure across the catalyst
  • A filtered crankcase ventilation system meeting EPA rule compliance
  • Meeting 70 dB noise limitations at the property line
  • All required testing for Florida Department of Environmental Protection

SOLUTIONS

The design-build effort was split into two phases with Phase I being the installation of the required equipment on the three largest and most highly used units, and Phase II being the installation of the required equipment on an additional seven units.

For both phases of the work, P&K was responsible for researching the available combination silencer oxidation catalysts best suited for the existing generators (based on flow rates, exhaust temperatures, piping configurations and accessibility). Additionally, P&K was responsible for reviewing available crankcase ventilation systems and researching available monitoring and data logging systems. Once the owner approved the proposed equipment, P&K was responsible for the purchase, installation, and permitting of all equipment. Comprehensive exhaust sampling tests on the catalysts were conducted in close coordination with the Florida Department of Environmental Protection (FDEP).

Work was completed with minimal disruption to daily operations of the facility. Regulations require a 70 percent reduction in carbon monoxide, but the client desired a 90 percent reduction for Phase I. Final independent testing in accordance with approved protocol of the three larger units that P&K designed and installed proved the system
achieves a 95 percent reduction in carbon monoxide. The performance exceeded the client’s expectations and far exceeded the minimum regulatory requirement.

BACKGROUND
