claus process in a sentence

"claus process" in Chinese  

SentencesmobileMobile

  • It is an alternative to, for example, the Claus process.
  • The Claus process is used in refineries to produce sulfur as a byproduct.
  • This reaction is exploited in the Claus process, an important industrial method to dispose of hydrogen sulfide.
  • The conventional Claus process described above is limited in its conversion due to the reaction equilibrium being reached.
  • First patented in 1883 by the chemist Carl Friedrich Claus, the Claus process has become the industry standard.
  • The physical properties of elemental sulfur obtained in the Claus process can differ from that obtained by other processes.
  • Using the so-called Claus process, hydrogen sulfide is afterwards transformed to elementary sulfur to be sold to the chemical industry.
  • The "'Claus process "'is the most significant gas desulfurizing process, recovering elemental sulfur from gaseous hydrogen sulfide.
  • The high temperature in the first stage also helps to hydrolyze CS 2, which is formed in the furnace and would not otherwise be converted in the modified Claus process.
  • The removed H 2 S is most often subsequently converted to by-product elemental sulfur in a Claus process or alternatively converted to valuable sulfuric acid in a WSA Process unit.
  • It's difficult to see claus process in a sentence .
  • The multi-step Claus process recovers sulfur from the gaseous hydrogen sulfide found in raw natural gas and from the by-product gases containing hydrogen sulfide derived from refining crude oil and other industrial processes.
  • However, the majority of the H 2 S treating plants utilize the modified Claus process, as the sulphur market infrastructure and the transportation costs of sulphuric acid versus sulphur are in favour of sulphur production.
  • The removed H 2 S is most often subsequently converted to by-product elemental sulfur in a Claus process or it can be treated in a WSA Process unit where the by-product is sulfuric acid.
  • The hydrogen sulfide removed and recovered by the amine gas treating unit is subsequently converted to elemental sulfur in a Claus process unit or to sulfuric acid in a wet sulfuric acid process or in the conventional Contact Process.
  • The tail gas from the Claus process still containing combustible components and sulfur compounds ( H 2 S, H 2 and CO ) is either burned in an incineration unit or further desulfurized in a downstream tail gas treatment unit.
  • The residual gas from the Claus process is commonly called " tail gas " and that gas is then processed in a tail gas treating unit ( TGTU ) to recover and recycle residual sulfur-containing compounds back into the Claus unit.
  • Of the processes available for these conversions, the Claus process is by far the most well known for recovering elemental sulfur, whereas the conventional Contact process and the WSA ( Wet sulfuric acid process ) are the most used technologies for recovering sulfuric acid.
  • Aluminium oxides are common catalysts for industrial processes; e . g . the Claus process to convert hydrogen sulfide to sulfur in refineries and to " supported " by alumina, meaning that the expensive catalyst material ( e . g ., platinum ) is dispersed over a surface of the inert alumina.
  • These processes are of great industrial and environmental importance as they provide the bulk of sulfur used in industry ( Claus process and Contact process ), sulfur-free compounds that could otherwise not be used in a great number of catalytic processes, and also reduce the release of harmful sulfur compounds into the environment, particularly sulfur dioxide ( SO 2 ) which leads to acid rain.
