  2. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main condenser. From the condenser, it is then pumped to the deaerated feed tank.

  3. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    A study found the mean concentration of sodium in softened water to be 278 mg/L. [23] In 2 liters of water—the amount of drinking water typically suggested for an average adult, this constitutes about 22% of the recommended sodium intake by the US CDC and may make a difference to those who need to significantly limit their sodium consumption.

  4. Dilution (equation) - Wikipedia

    en.wikipedia.org/wiki/Dilution_(equation)

    For example, if there are 10 grams of salt (the solute) dissolved in 1 litre of water (the solvent), this solution has a certain salt concentration . If one adds 1 litre of water to this solution, the salt concentration is reduced. The diluted solution still contains 10 grams of salt (0.171 moles of NaCl).

  5. Caustic embrittlement - Wikipedia

    en.wikipedia.org/wiki/Caustic_embrittlement

    Inside the cracks, the water evaporates and the amount of hydroxide keeps increasing progressively. The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes ...

  6. Circulation evaporator - Wikipedia

    en.wikipedia.org/wiki/Circulation_evaporator

    These include processes that produce salt, corn steep water and calcium carbonate. [9] Natural circulation evaporators are used in other processes such as those that produce anhydrous sodium hydroxide (caustic), sugar beet, liquors that are particularly foamy, or those that have a low to moderate viscosity, and precipitating liquids. [15]

  7. Lye - Wikipedia

    en.wikipedia.org/wiki/Lye

    A lye refers to sodium hydroxide and potassium hydroxide. The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH). In order to distinguish between the two, sodium hydroxide may be referred to as soda lye while ...

  8. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...

  9. Prices of chemical elements - Wikipedia

    en.wikipedia.org/wiki/Prices_of_chemical_elements

    As chlorine is manufactured together with sodium hydroxide in chloralkali process, relative demand for one product changes the price for the other. When demand for sodium hydroxide is relatively high, chlorine price can fall to arbitrarily low levels, even to zero. [30] 18: Ar: Argon: 0.0017837: 3.5 (9.695 × 10 16 kg) 0.931: 0.001 66: 2019 ...
