• ODORANT FOR FUEL GAS
  申请人：SODA AROMATIC COMPANY, LIMITED

  公开号：EP1457547A1

  公开（公告）日：2004-09-15

  The present invention provides an odorant suitable for use in fuel gases, such as liquefied natural gas (LNG), city gas, and LP gas, or methane gas, propane gas, butane gas and hydrogen gas. Preferably, the present invention provides a novel odorant that can also be used for fuel gases for fuel cells, including hydrogen gas. The odorant for fuel gases of the present invention has a perceptual threshold of 1 ppb or less, and includes a compound that has no sulfur atoms and no nitrogen atoms in its molecules. The odorant for fuel gases of the present invention is suitable for use in fuel cells that use hydrogen gas or other gases as a fuel.

  本发明提供了一种适用于燃料气体的臭味剂，如液化天然气（LNG）、城市煤气和液化石油气，或甲烷气、丙烷气、丁烷气和氢气。优选地，本发明提供的新型臭味剂也可用于燃料电池的燃料气体，包括氢气。 本发明的燃料气体臭味剂的感知阈值为 1 ppb 或更低，包括一种在其分子中没有硫原子和氮原子的化合物。本发明的燃料气体气味剂适用于使用氢气或其他气体作为燃料的燃料电池。

• PROCESS FOR CRYOGENIC FLUID ODORISATION
  申请人：Arkema France

  公开号：US20200157446A1

  公开（公告）日：2020-05-21

  The present invention relates to a process for odorizing a cryogenic fluid, comprising a step a) of continuously feeding an odorizing agent in liquid or gaseous form into a feed zone, said feeding being carried out at a temperature above the temperature of the cryogenic fluid and above the crystallization temperature of the odorizing agent, a step b) of feeding said odorizing agent in liquid or gaseous form from step a) into a buffer zone in which the liquid or gaseous odorizing agent is brought to a temperature of about the temperature of the cryogenic fluid, and a step c) of feeding said odorizing agent cooled in step b) into the contact zone, wherein said odorizing agent comes into contact with said cryogenic fluid to be odorized. The present invention also relates to an odorizing device for implementing said odorizing process.
