Gas Hydrate Desalination

Posted on August 28, 2013 by zerbe

Interesting way to desalinate salty water. Gas hydrate consists of only water and a gas, such as methane, the stuff of natural gas. When hydrates form, salts and other impurities are left behind. Hydrates were formed from water and carbon … Continue reading →

Salt Water freezing temperatures

Posted on June 22, 2010 by zerbe

The freezing temperature of salt water depends on how much salt you put in. Oceanographers define the “salinity” of water as the number of grams of salt per 1000 grams of water. (Since 1000 grams of water is almost exactly … Continue reading →

Density of Salt Water (Seawater)

Posted on June 21, 2010 by zerbe

The density of surface seawater ranges from about 1,020 to 1,029 kg•m−3, depending on the temperature and salinity. Deep in the ocean, under high pressure, seawater can reach a density of 1,050 kg•m−3 or higher.

Subsea Sea Water

Posted on June 21, 2010 by zerbe

Seawater is denser than fresh water because of the salts’ added mass. The freezing point of sea water is about -2 ºC. Deep in the ocean, under high pressure, seawater can reach a density of 1,050 kg•m−3 or higher. From … Continue reading →
