Wastewater Technology Fact Sheet: Oxidation Ditches

The oxygen transfer efficiency of oxidation ditches ranges from 2.5 to 3.5 lb./Hp-hour (Baker Process, 1999). The design criteria are affected by the influent wastewater parameters and the required effluent characteristics, including the decision or requirement to achieve nitrification, denitrification, and/or biological phosphorus removal ...

Liquid Stream Fundamentals: Aeration Design

DO. The Actual Oxygen Transfer Rate (AOTR or OTRf) is the rate at which AOR is transferred under field conditions. A variety of factors influence the OTRf, and the quantity of oxygen delivered to a process fluid must exceed the AOR value to account for the reduced transfer efficiency in process water versus standard tap water. To determine the

Industrial Oxygen: Its Use and Generation

liquid oxygen, nitrogen is used as the heat transfer fluid to further cool the oxygen. Cryogenic separation is most effective when any of the three criteria need to be met: high purity oxygen is required (>99.5%), high volumes of oxygen are required (≥102 tons of oxygen/day), or high pressure oxygen is required.

Oxygen Enriched Combustion Process - Energy

flame temperature, increased heat transfer to the load, and reduced flue gas. Using oxygen-enriched combustion for specific applications may improve efficiency, depending on the exhaust gas temperature and percentage of oxygen in the combus-tion air. Figure 2 can be used to calculate energy savings for commonly used process heating applications.

AISI | Electric Arc Furnace Steelmaking

Chemical energy is be supplied via several sources including oxy-fuel burners and oxygen lances. Oxy-fuel burners burn natural gas using oxygen or a blend of oxygen and air. Heat is transferred to the scrap by flame radiation and convection by the hot products of combustion. Heat is transferred within the scrap by conduction.

06 Mass Transfer and Its Applications

the transfer of material from one homogenous phase to another. The driving force for transfer is a concentration difference or a concentration gradient; much like a temperature difference or a temperature gradient provides the driving force for heat transfer. These methods, covered by the term mass-transfer operations,
