Date Dec. 23, 1992.A method is described for reducing the total emissions during cold starts from an engine burning a hydrocarbon fuel and having an afterburner arranged upstream of a catalytic converter. The method comprises the steps of: (i) adding an excess of fuel to the engine combustible charge and adding air to the engine exhaust gases immediately after the engine has first fired to assure the presence in the exhaust/air mixture of sufficient concentrations of hydrogen and oxygen to permit the resulting exhaust/air mixture to be ignitable and to burn with a steady flame in the afterburner while the latter is at a temperature close to the ambient temperature, and (ii) igniting the exhaust/air mixture in the afterburner immediately after the engine has first fired. In the preferred embodiment of the invention, the excess fuel and/or the additional air are regulated after ignition has occurred in the afterburner to maintain a steady flame in the afterburner until at least part of the matrix of the catalytic converter has reached its light off temperature.

Filed: 1986-06-12
Abstract: An aqueous effluent is supplied to a stripping column (total stripping column) from which a mixture that is rich in NH3, CO2 and H2S is withdrawn as a head product. In at least one additional stripping column the mixture is separated into a mixture which is rich in NH3 and a mixture which is rich in the sour gaes CO2 and H2S. The mixture which is rich in NH3 is scrubbed with liquid ammonia. The overhead product from the total stripping column is cooled in a condenser under a pressure of 1 to 7 bars and is thus transformed into a liquid phase to such an extent that the liquid phase contains 70 to 100% of the NH3 which has been supplied to the condenser. The liquid phase is supplied at a temperature of 30 DEG  to 90 DEG  C. to a second stripping column (NH3 stripping column), which is operated under a pressure of 1 to 4 bars and from which a gas mixture that is rich in NH3 is withdrawn as a head product. The gas mixture is scrubbed with water and ammonia and the NH3 gas which has been scrubbed is condensed.

Title: Medium consistency ozone bleaching
Inventor: HENRICSON KAJ
IPC: D21C9/153
Filed: 1992-03-30
Abstract: In a method of bleaching medium consistency pulp with ozone using a mixer (12), ozone containing gas and about 6-15% consistency pulp are fed (from 22) to the mixer, and then discharged in a first, preferably vertical, path (14, 16). The mixture of pulp and ozone moves in a first part of the vertical path a time period of about 1-5 seconds at a velocity of about 1-5 m/s so that the gas and pulp do not separate during movement in this first part, and the vast majority of the pulp brightening reaction between the ozone and pulp takes place. This is preferably accomplished by passing the mixture upwardly in a small diameter conduit (14) having a height of about 3-20 meters. Then the velocity of the pulp is slowed while still moving in the first path, preferably by feeding it directly to a much larger diameter (e. g. 1.5-10 times) conduit (16), so the height of the unit may be kept under 100 feet. The pulp flows in the large diameter conduit for about 0.5-5 minutes so that residual reactions take place. The pulp then flows into a second path (27) distinctly different from the first path. <IMAGE>
