  • Anti-pollution Measures
CONT

Amine Sweetening Process... Rich amine is heated by hot regenerated lean amine in the heat exchanger. Rich amine is then further heated in the regeneration still column, by heat supplied from the reboiler. The steam rising through the still liberates H2S and CO2 and therefore regenerates the amine. Steam and acid gases separated from the rich amine are condensed and cooled, respectively, in the reflux condenser. Condensed steam is separated in the reflux accumulator and returned to the still. Acid gases may be flared or directed to an acid gas recovery system.

Acid cleaning :[the] use of hot acids to remove dirt or polishing residue from diamonds. Newly-mined rough diamonds are cleaned with hydrofluoric acid; newly-polished diamonds are boiled in a solution of hydrochloric and sulfuric acids to remove oil, graphite, and other debris from surface fractures and abrasions. Diamonds which have been mounted in jewelry are sometimes boiled in sulfuric acid to remove metal residue and dirt impregnated in the girdle.

  • Chemical Elements and Compounds
CONT

The salts of hydrochloric acid, known as chlorides, can, in most cases, be prepared by dissolving either the metal, its hydroxide, oxide, or carbonate in the acid; or by heating the metal in a current of chlorine, or by precipitation. The majority of the metallic chlorides are solids(stannic chloride, titanic chloride and antimony pentachloride are liquids) which readily volatilize on heating. Many are readily soluble in water, the chief exceptions being silver, chloride, mercurous chloride, cuprous chloride and palladious chloride which are insoluble in water, and thallous chloride and lead chloride which are only slightly soluble in cold water, but are readily soluble in hot water.

CONT

Chlorine induced corrosion is the most important corrosion process in power plants, firing waste, coal and/or biomass. Depending on the process, chlorine is present as HCl gas, as solid KCl and NaCl in ashes or as eutectic melts i.e. KCl-ZnCl2 in deposits of waste fired boilers. In the presence of HCl gas and solid chlorides, "active oxidation" is generally accepted as the major corrosion mechanism. Metal chlorides are formed by inward diffusion of chlorine to the metal/oxide interface, evaporating and subsequently oxidized to non-protective oxides and additional chlorine.

French

  • Éléments et composés chimiques
CONT

Parfois [...] il se dépose des oxydes, sulfures et chlorures métalliques accompagnés de minéraux constituant la gangue [...]

OBS

Dans les dénominations de familles de composés, l'adjectif anglais «metallic» ou le terme anglais «metal» employé adjectivement se traduisent en français par «métallique» de préférence à «de métal». P. ex. : acétylures métalliques, azides métalliques, azotures métalliques, carbonoperoxoates métalliques, chlorures métalliques, cyanures métalliques, hydroxydes métalliques, hydrures métalliques, nitrates métalliques, sels métalliques, stéarates métalliques et sulfures métalliques (tournures plus naturelles que celles formées avec «de métal»). En revanche, lorsqu'il est nécessaire de préciser la nature du métal (métaux alcalins, métaux alcalino-terreux, métaux de transition, métaux des terres rares, métaux lourds, etc.), il est préférable, pour éviter toute ambiguïté, d'utiliser la locution «de métal». P. ex. : peroxydes de métaux de transition (et non «peroxydes métalliques de transition»), peroxydes de métaux alcalins (et non «peroxydes métalliques alcalins»).

a pit ... tank into which the contents of a digester are blown at the completion of a cook in papermaking.

CONT

Three methods of discharging the digester are used in the sulfite processes-hot blowing, cold blowing, and flushing. The emission of sulfur dioxide from the blow pit or dump tank depends on the system of blowing(...) In the hot-blow style, the digester gases are used to discharge the contents of the digester to the blow pit. If no scrubbing is utilized emissions may range from 100 to 150 lb sulfur dioxide per ton of air dried pulp. In the cold blow and flushing style of discharge, the pressure is almost fully relieved from the digester and the relief gases are routes to accumulators for fortifying cooking acid. The contents of the digester are then discharged into a dump tank. Emissions from this source, if no secondary scrubbing is utilized, may range from 10 to 25 lb sulfur dioxide per ton of air dried pulp.
