co-containing tail gas utilization - 0 views

  •  
    In industrial production, such as steel industry, petroleum and chemical industry, mass of CO, as "waste", was not good used, for example: blast furnace gas, converter gas, yellow phosphorus tail gas, chemical tail gas, calcium carbide tail gas, garbage incineration gas, etc. Above gases are all rich in CO gas, can be used as secondary energy. PKU PIONEER developed a new VPSA-CO separation and purification technology. The new technology can recovery CO from secondary energy, and used it as chemical raw materials. By this way, it can greatly reduce CO2 emissions, save fossil energy, has good economic and social benefits.

Chemical Engineering Lab Equipment Manufacturer - 1 views

  •  
    Chemical engineers figure out how to do it efficiently, safely, and economically. They're like the chefs of the industrial world, creating the instructions for making stuff in factories. Chemical engineering lab equipment manufacturers are proud to be collaborators with chemical engineers worldwide.

Chemistry - Wikipedia, the free encyclopedia - 0 views

  • Chemistry
  • Chemistry, a branch of physical science, is the study of the composition, structure, properties and change of matter.
  • Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds.

  • Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.
  • Chemistry is a branch of physical science but distinct from physics.
  • Etymology
  • The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.
  • Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies
  • An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
  • The word alchemy in turn is derived from the Arabic word al-kīmīā (الکیمیاء). In origin, the term is borrowed from the Greek χημία or χημεία.
  • This may have Egyptian origins.
  • Many believe that al-kīmīā is derived from the Greek χημία, which is in turn derived from the word Chemi or Kimi, which is the ancient name of Egypt in Egyptian.

Article How To Differentiate Smokeless Gun Powder by Hanging Drop Technique - 0 views

  •  
    Bulk smokeless gunpowder is manufactured in a large variety of shapes, sizes, and textures, many different types look similar, making it challenging to differentiate between types of powders. One chemical discriminating parameter is the presence of nitroglycerin, which often requires expensive instrumentation to be detected. By using the Hanging drop technique, whereby a sample is induced to react inside a drop hanging over it after, it is possible to differentiate between single and double-base smokeless powders. The method resulted in a successful, time effective, and non-destructive result for the detection of nitroglycerin. For more info : http://scidoc.org/IJFP-2332-287X-04-901.php
