Übersetzung für "Gegenstromverfahren" in Englisch

Extraction by leaching: It was decided that a two-stage pro cess of extraction be leaching in counterflow conditions would be undertaken.

The column is operated in the counter current flow process.

There occurs a cooling of the hot medium in a countercurrent process.

The rotary kiln is operated in counter-current mode and heated directly by means of a gas burner.

As a result of said aperture, it then becomes possible to guide air in the counterflow method.

Also a combined operating mode from bath change and counterflow method is known.

The matrix is cleaned from time to time preferably in a counter-current procedure.

The column (3) is operated on the countercurrent principle.

Said dialysis was carried out in a countercurrent process.

In the counter current process, moist gas and dry gas encounter each other in the absorption column.

In this counterflow procedure, the top-down impulses are complemented by business-specific bottom-up perspectives.

The process of claim 1, which comprises carrying out the reaction in countercurrent direction.

In a countercurrent process that drag effect is particularly important because it opposes a backdrifting of the particles.

The dry air is passed in a countercurrent through the air dryer 14 and discharged to the atmosphere.

Both processes can be carried out discontinuously with stationary adsorbent layers and continuously in the countercurrent process.

The reaction product is then, preferably, extracted by the counter-current method in a manner known to those skilled in the art.

A counterflow method, whereby the air would be evacuated from the top of the tower, also is suitable.

This is done in tower systems, where the pulps are de-sugared in countercurrent flow with hot water.

Just as in the smaller laboratory devices, the spraying application took place by a countercurrent process (top spraying).

To carry out process step (a), namely the hydrolysis in counter-current, the water is passed into the upper zone of the hydrolysis section and the methyl formate into the lower zone of the hydrolysis section of the column.

Surprisingly, it is found that with a 4-stage absorption process it is already possible to achieve NOx off-gas values which can otherwise be achieved only with a larger number of stages in the counter-current process.

The process according to the invention is carried out as parallel flow process, in which loading of the exchanger and the elution step are carried out in the same direction of flow or, preferably, as countercurrent process, in which loading and elution are carried out in opposed directions of flow.

"Solution I" is extracted with water-immiscible, organic solvents in accordance with customary methods (shaking, counter-current processes and the like).

Within the scope of the fluid flow method, the so-called countercurrent method is preferred for different reasons, whereby the washing zone (rinsing zone) located at the end of the washing machine is supplied via a feed conduit with fresh water which traverses the machine upon leaving the rinsing zone then with a partial current in counterflow to the laundry, while the preponderant residual current of the liquid fed at the end of the washing machine is supplied via a connection with the loading and soaking zone located at the start of the washing machine and designated here as a soaking conduit.

In addition, the objective of the present invention is to create a continuous washing machine of the initially described kind, which in addition is appropriate for washing laundry items of the same kind, in order to launder them in a manner known from prior art per se, according to the economical countercurrent method.

The invention provides as a solution of the problem that laundry items of a preponderantly present first kind (that is white laundry) are laundered in a manner known per se according to prior art, under the countercurrent method, and that laundry items simultaneously present in the washing machine, of a second kind present in a lesser amount (for example multicolored laundry items or woolen fabrics) are laundered in a manner known per se according to prior art under the multi-lye method, whereby the partial current flowing in countercurrent to the laundry is fed from a laundry compartment containing laundry of the first kind and transported, by-passing a laundry compartment containing laundry of the second kind, to the next laundry compartment located in the direction of the countercurrent and containing laundry of the first kind.
