Case Study

Chemical company improves regional air quality by vastly reducing emissions

Every Challenge Has a Backstory

A global chemical company and a major manufacturer of sodium nitrite in North America was in need of an air pollution control (APC) system to reduce nitrogen oxide (NOx) emissions from its production of sodium nitrite. Sodium nitrite is used in various industrial applications from manufacturing dyes to food preservatives.

The goal for the new APC system was to reduce NOx emissions by 90% to comply with the one-hour National Ambient Air Quality Standard (NAAQS) for nitrogen dioxide. The project also needed to be completed on an expedited schedule to meet the regulatory compliance deadline.

OBG’s Focus on Solutions

The chemical company looked to OBG’s unique air pollution control experts to establish the process design basis and APC performance requirements; facilitate a technology risk assessment and contingency planning; identify appropriate APC technologies; and develop a preliminary engineering package. OBG also moderated a critical hazards and operability study to identify key process operations and mitigate design and operational risks.

Results that Matter

OBG completed the preliminary design for this complex system cost effectively and within the expedited project schedule to meet regulatory compliance deadlines. The new APC system is fully operational and has reduced the manufacturer’s NOx emissions by its goal of 90%, or several hundred tons of NOx per year. The client has received accolades from New York State for its commitment to environmental protection.
