Chromium electroplating is an essential DOD process. Chromium has a combination of qualities that are very difficult to substitute, however, the process itself is inefficient, resulting in the production of byproduct gases that rise and create a mist of chromic acid (strongly regulated as an air pollutant) above the plating tank. Venturi/Vortex Scrubber Technology (VVST) was designed to control chromium electroplating emissions by collecting the gas bubbles before they burst ...
In the electron disturbed upper atmosphere, electronically excited metastable forms of oxygen and nitrogen are formed by electron impact processes. These species dissipate their energy into the atmosphere largely by collisional quenching and chemical reaction. Specific species and reactions of interest include: 1) electronically and/or vibrationally excited nitrogen, N2*, its spectroscopy, energy pooling and interactions with Oxygen, O2 and trace, infrared-active atmospheric species such as CO, CO2, and Nitric Oxide; ...
