About RICE NESHAP
The first RICE NESHAP (Reciprocating Internal Combustion Engine National Emission Standards for Hazardous Air Pollutants) regulation was enacted in 2004 for existing >500 Hp gas engines at major pollution sources. The EPA’s 2008 RICE NESHAP affected new engines.
The 2010 RICE NESHAP (40 CFR Part 63, Subpart ZZZZ) sets limits for emissions of formaldehyde, acetaldehyde, acrolein, methanol and nearly 200 other toxic compounds from stationary diesel and gas engines, focusing on formaldehyde as the regulated emission.
However, the EPA has determined that carbon monoxide (CO)is an appropriate surrogate for formaldehyde. Since testing for CO has many advantages over testing for HAPs most of the emission standards have been finalized using CO as the only regulated pollutant.
The vast majority of existing stationary engines are regulated in some fashion by the 2010 RICE NESHAP. These engines must be in compliance by:
• Non-Emergency Diesel (CI) Engines by May 13, 2013.
• Non-Emergency Gas (SI) Engines by October 13, 2013.
The startup, shutdown and malfunction (SSM) requirements for RICE NESHAP have been in effect since 2010. Existing emergency stationary RICE located at residential, institutional, or commercial area sources of HAPs emissions are exempt from the 2013 requirements.
The 2010 RICE NESHAP is summarized in the table in Related Documents below.
RICE NESHAP affects diesel and gas engines used in a variety of industries including chemical and petrochemical, gas production, processing and storage, municipal water pumping and a number of manufacturing processes. They are used to generate power for electricity demand, gas compression
Johnson Matthey Products for RICE NESHAP
There are many reasons for engine owners/operators to choose Johnson Matthey for complete and cost-effective RICE NESHAP compliance.
At Johnson Matthey, we know catalysts and we know stationary engines. We have been established since 1817 and we are the only company that has unmatched expertise in both catalyst science and converter housing design. We introduced the original hatchback catalytic converter—the first converter to allow easy access to the catalyst element. We continually improve our products and have optimized our latest generation of converters for your RICE NESHAP applications.
Our new modular Modulex TM catalytic converters and converter-silencers are designed specifically for removing HAPs and CO to meet the emission limits of the RICE NESHAP regulation.
The low-cost modular design is available in either carbon steel or stainless steel and each model has an access hatch to allow you to add, replace or clean the catalyst element.
• Each Modulex catalytic converter is designed specifically for your engines.
• We back every Johnson Matthey product with highly responsive field service and technical support. Our quality and service are unmatched.
A key component of Johnson Matthey Modulex HAPs converters is the catalyst itself. The high performance catalyst elements are constructed of stainless steel foil that is brazed to give extraordinary strength and prevent unraveling or telescoping. They are coated with platinum, the most active element for catalytic destruction of HAPs and CO. We design, develop and manufacture the catalyst.
