Both experimental and numerical studies have been conducted to improve ozone production rates in oxygen.(13–20) Eliasson et al.(13) provided the most detailed model of ozone production in dielectric barrier discharges.
It was found that the rotating glow discharge jet could produce about 5 × 10 17 cm −3 of nitric oxide under optimized conditions, while the density of nitrogen dioxide was three orders of magnitude lower, and the density of ozone and other harmful species were below or close to the detection limit of used analytical devices. Moreover, the. A system for producing a mixture comprising nitric oxide and air for treatment of medical conditions. The invention enables unlimited production of nitric oxide at any location using only air and a source of electricity. An electric arc chamber 4 is provided with electrodes 5 separated by an air gap 9. An electric circuit 7 supplies a high voltage potential to the electrodes 5 and induces an.
The energy required to produce the O(3 P) and O(1 D) radicals from oxygen will rise respectively to kJ mol –1 and kJ mol – energy can only be supplied by: a high voltage electrical discharge into the oxygen stream; electrolysing the water;. A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically neous corona discharges occur naturally in high-voltage systems unless care is taken to limit the electric field strength. A corona will occur when the strength of the electric field (potential gradient) around a conductor is high enough.

Nitric oxide (NO) is a vasodilator and antihypertensive agent as well as a universal anti-microbial factor killing bacteria, fungi and parasites without killing human cells provided that an appropriate dose level and treatment time are applied.

The electric arc plasma was used in the B-E process, in which 1% of nitric oxide was achieved, and subsequently used for the production of HNO 3 with an energy consumption of MJ/mol [27, Nitric oxide formation by electrical discharge is thought to be via the Zel'dovich mechanism.
At high temperatures the gas mixture heated by the discharge is thought to be in chemical equilibrium, with the equilibrium concentration of NO, ([NO] equil.

Laboratory experiments were performed to estimate the production of NO x and O 3 in streamer discharges in a coaxial cylindrical cell in atmospheric air pressure.
A standard lightning impulse voltage (/50 μs) applied to the central wire of the cell created streamer discharges in the space between the central wire and the inner cylinder and the produced NO x and O 3 was measured by.
A coupled surface dielectric barrier discharge is reported and compared with a surface dielectric barrier discharge with respect to the spatial distribution of the plasma streamers, the energy dissipation in the discharge plasma, the scalability of the discharges, and their efficiency for ozone synthesis and nitric oxide conversion from air.
Producing nitric oxide by pulsed electrical discharge in air for portable inhalation therapy. Both generators use pulsed electrical discharges to produce therapeutic range NO (5 to 80 parts per million) at gas flow rates of to 5 liters/min. NO was produced from air, as well as gas mixtures containing up to 90% O2 and 10% N2.
Introduction. Nitric oxide (NO) is a selective pulmonary vasodilator that was approved by the U.S. Food and Drug Administration in for the treatment of hypoxic term or near-term newborns with persistent pulmonary hypertension (PPHN).Since approval, inhaled NO has predominantly been used in major medical centers of the developed world to treat pulmonary hypertension in newborns, and.
The production rate of all nitrogen oxides produced increased significantly with N 2 concentration while H 2 O 2 formation decreased slightly. The gas temperature of the plasma was approximately K and was unaffected by N 2 concentration while the electron density ranged from 1 × 10 17 cm −3 in pure Ar to × 10 17 cm −3 in 28% N 2.
Inhalation of nitric oxide (NO) produces selective pulmonary vasodilation and is an effective therapy for treating pulmonary hypertension in adults and children. In the United States, the average cost of 5 days of inhaled NO for persistent pulmonary hypertension of the newborn is about $14, NO therapy involves gas cylinders and distribution, a complex delivery device, gas monitoring and.
By varying air flow rate, ozone, nitric oxide and nitrogen dioxide concentrations were measured, as presented in Fig. 8. The nitric oxide graph is not shown because its amount was always below the measuring limit of our equipment.
