The distillation of coal for the production of gas, coke and the tarry materials used for the manufacture of dyes and organic chemicals results in a watery waste known as ammoniacal gas liquor, and the disposal of this is a cause of pollution. Ammoniacal gas liquor contains free ammonia, ammonium salts, cyanide, sulphide, thiocyanate, and a variety of aromatic compounds including pyridine, phenols, cresols and xylenols.... Gas liquor, discharged untreated to a stream, has an extremely high oxygen demand, many times greater than that of sewage.  1, fiche 1, Anglais, - ammoniacal%20gas%20liquor

The Turbotak Scrubber: TurboSonic’s proprietary spray nozzle systems are used to finely atomize scrubbing liquids into literally trillions of droplets. These droplets are the vehicle for removal of solid, liquid and gaseous contaminants from process exhaust gas streams. This approach is dramatically more efficient than "conventional" packed tower and venturi scrubbers.  3, fiche 2, Anglais, - scrubbing%20liquid

A packed tower scrubber removes soluble and noxious gases, and mists with droplet sizes greater than 5 µm, from gas streams. Contaminant gases, such as hydrochloric acid, sulphur dioxide and ammonia vapour, are made to flow through a bed packed with media. The media can be plastic, ceramic or stainless steel rings or saddles, designed to provide a high surface area yet allow a high throughput. A scrubbing liquor is pumped through the bed, intimately mixes with the gas stream and dissolves the contaminant gases.  2, fiche 2, Anglais, - scrubbing%20liquid

Basé sur le principe de fonctionnement de l'éjecteur à jet de liquide, les laveurs de gaz sont un moyen économique de résoudre les problèmes de nocivité des gaz d'échappement en les lavant, les purifiant, les neutralisant, éliminant dans leur quasi-totalité les fumées et les odeurs polluantes. Dans certains cas où les gaz sont à une température trop importante, le liquide de lavage peut servir à les refroidir. Pour l'épuration des gaz odorants, le liquide de lavage doit comporter une solution chimique capable d'interagir avec le gaz traité.  1, fiche 2, Français, - liquide%20de%20lavage

L'absorbeur Turbotak : Les systèmes exclusifs de becs pulvérisateurs de la société TurboSonic sont utilisés pour pulvériser finement les liquides absorbeurs en une multitude de petites gouttelettes. Ces gouttelettes permettent de retirer les polluants solides, liquides et gazeux des jets de gaz d'échappement produits par différents procédés. Cette méthode, qui fait usage de jets pulvérisés, est beaucoup plus efficace que les absorbeurs conventionnels à tours à garnissage et les absorbeurs venturi.  2, fiche 2, Français, - liquide%20de%20lavage

A representative medium-consistency system is shown in Figure 11-19. Pulp from a brown stock washer or decker at about 10-14% consistency is charged with caustic or oxidized white liquor. It is then preheated in a low-pressure steam mixer and pumped through one or more medium-consistency gas mixers to an upflow pressurized reaction tower. Steam and oxygen are added upstream of the medium-consistency mixer or are added directly into it. The reactor bottom may be hemispherical or conical, and the top is equipped with a discharger.... The stock is depressurized through a separator where steam is flashed and small amounts of by-product gases, oxygen and other noncondensibles are released.  1, fiche 3, Anglais, - medium%2Dconsistency%20oxygen%20delignification

High-Consistency System. Figure 11-18 shows a representative system where pulp is handled in the 25% to 28% consistency range. Typically, a press is used to raise the feed consistency to about 30%. Fresh caustic or oxidized white liquor along with the magnesium protector is added to the pulp at the discharge of the press. A thick stock pump then transfers the pulp to a fluffer via a feed pipe in which a gas-tight plug is formed. The fluffed pulp flows down the pressurized reactor as a loose bed, while gaseous oxygen is continuously dissolved into the liquid phase and reacted with the pulp.... Oxygen gas is added to either top or bottom to maintain a partial pressure within the 90 to 130 psi range. Relief is taken from the head space at the top of the tower to remove combustibles and other noncondensible gases, and control overall reactor pressure. At the bottom of the tower, the reacted pulp is diluted with post-oxygen filtrate and pumped at about 6% consistency to a blow tank.  2, fiche 4, Anglais, - high%2Dconsistency%20oxygen%20delignification

The gas from the first stage scrubber goes to the second stage wet scrubber where ammonia, solids, and fluoride are further removed in the scrubbing liquor. These second stage scrubbers also vary from plant to plant that could include impinger scrubber, venturi scrubber ring end cone scrubber, two-stage cyclonic scrubber.  1, fiche 6, Anglais, - two%2Dstage%20cyclonic%20scrubber
