2. Sparging (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Sparging_(chemistry)

   Sparging introduces a gas that has little or no partial pressure of the gas(es) to be removed, and increases the area of the gas-liquid interface, which encourages some of the dissolved gas(es) to diffuse into the sparging gas before the sparging gas escapes from the liquid. Many sparging processes, such as solvent removal, use air as the ...

3. Fouling - Wikipedia

   en.wikipedia.org/wiki/Fouling

   Precipitation fouling is a very common problem in boilers and heat exchangers operating with hard water and often results in limescale. Through changes in temperature, or solvent evaporation or degasification , the concentration of salts may exceed the saturation , leading to a precipitation of solids (usually crystals).

4. Nonpoint source pollution - Wikipedia

   en.wikipedia.org/wiki/Nonpoint_source_pollution

   Nonpoint source water pollution may derive from many different sources with no specific solutions or changes to rectify the problem, making it difficult to regulate. Nonpoint source water pollution is difficult to control because it comes from the everyday activities of many different people, such as lawn fertilization , applying pesticides ...

   en.wikipedia.org/wiki/Basic_sediment_and_water

   Basic sediment and water (BS&W) is both a technical specification of certain impurities in crude oil and the method for measuring it. When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation. The particulate matter is known as sediment or mud.

6. Flash-gas (petroleum) - Wikipedia

   Oil and Natural Gas Refinery in Turkey. In an oil and gas production, flash-gas is a spontaneous vapor that is produced from the heating or depressurization of the extracted oil mixture during different phases of production. [1] Flash evaporation, or flashing, is the process of volatile components suddenly vaporizing from their liquid state.

7. Residence time - Wikipedia

   en.wikipedia.org/wiki/Residence_time

   The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
