  • Chemical Aspects of NOX Scrubbing

    With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOX (Nitrogen Oxides) produced. NOX is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NO2 + Hv ...


  • NOx Scrubbing Technology Breakthrough

    Pacific Rim Design and Development and Dupont are proud to introduce a technology breakthrough in the treatment and safe elimination of problematic nitric oxide (NO) and nitrogen dioxide (NO2 ).  There are six forms of nitrogen oxide (NOx); the drawings to the right show the two most problematic forms.  These two are of particular interest because they are identified as atmospheric ...

  • NOx in Non-Utility Industries - Part II - Control options and monitoring methodology

     This the second in a two-part series. Part I, which appeared in our June 2001 issue focuses on air emission origins of nitrogen oxides (NOx) in non-utility industries. Choice of the NOx control technology is dependent on many factors, including regulatory requirements, technical feasibility, cost and public perception. Figure 1, compiled based on publications [1-5], presents a summary of ...

In particular, we recommend our sample conditioning unit to those of you who need to take accurate, low NOx or SO2 ...

  • Model-based evaluation of mechanisms and benefits of mainstream shortcut nitrogen removal processes

    The main challenge in implementing shortcut nitrogen removal processes for mainstream wastewater treatment is the out-selection of nitrite oxidizing bacteria (NOB) to limit nitrate production. A model-based approach was utilized to simulate the impact of individual features of process control strategies to achieve NO−2-N shunt via NOB ...

  • Influence of streamer-to-glow transition mode on the NO removal by an inductive energy storage type pulse power generator

    Influence of streamer-to-glow transition on NO removal from a simulated diesel exhaust gas is described in this paper. A coaxial cylinder nonthermal plasma reactor was driven by an inductive energy storage pulse power generator employing a fast recovery diode as semiconductor opening switch. The NO removal increased with input energy into the reactor. The energy efficiency for 30% NO removal was ...

  • Nitrous oxide (laughing gas) - Case Study

    Example: Uranium enrichment Similar tasks: Nitric acid caprolactam production When uranium ore is converted into uranium hexafluoride (UF6) for uranium enrichment employing the diffusion process, or also when producing nitric acid and nitrogenous fertilizers for farming, laughing gas is produced by several undesirable side reactions. Thermal decomposition ...

  • Federal transport rule — the “new cair” round 1

    On August 2, 2010, EPA proposed the long- awaited replacement for the Clean Air Interstate Rule (CAIR), which was rejected in 2008 by the D.C. Circuit Court of Appeals. Now called the Transport Rule (TR) by EPA, the new rule revises the CAIR approach to conform with the court ruling. In this first version (Round 1) of TR, overall emission budgets for NOX are similar to the initial period in CAIR; ...
