Translation of "Energetischer aufwand" in English

However, a relatively high outlay is required in the pretreatment for these processes, for example a high outlay of energy if polymers are removed by distillation and a high outlay of investment is hydrogenated product streams are recycled.

Moreover, long reaction times and, at least at the start of the reaction, frequently low temperatures are required (EP-A-O,315,234, WO-A-89/02,453), which results not only in correspondingly lower space/time yields, but also in higher expense on equipment and/or energy.

However, all these processes necessitate treatment of the effluent or a great technical effort and energy expenditure.

The disadvantages of the pellet process lie in a considerably greater energy input, in the risk that acetaldehyde is formed, and that foreign plastics may coalesce, so that no homogenous PET is obtained.

The specific cumulative energy demand (CED) for production is 0.25 kWhprimary/kWhel.

A synthesis method providing for a good yield of the complex-forming substance cucurbituril was developed, which also exhibits a high degree of process reliability and reproducibility, as well as low energy consumption when applied on an industrial scale.

Their manufacture requires a significant use of energy, particularly in the form of the heat supplied to link the rubber.

This is why the energy consumption required for desorption is so high.

However, the active system requires a correspondingly high expenditure in apparatus and energy.

This multistage method requires a considerable outlay in terms of apparatus, energy and time.

As an advantage must be seen the low cost of instrumentation and energy in this process.

The energy expenditure for the heating thus can be kept small.

The expenditure of energy for the production of oxygen and thus the loss of efficiency is reduced in this way.

These can be worked up only with great energy expenditure to give sulphuric acid.

This process requires a considerable input in energy and machinery.

The production of biodiesel involves a high technical and energetic input.

This minimises energy costs for the hybrid system.

Because the energy cost is high, the female generally only has one offspring in a two years span.

Are the technical, energy, and material costs of realising the idea justified?

Such hybrid solutions having an electric drive and a hydraulic support require a comparatively high expenditure in terms of devices and energy.

The practical implementation of the processes is also sometimes associated with considerable technical and energy expenditure.

In this connection, the conventional de-icing measures are associated with high energy expenditure during the flight.

The high temperatures in our process, in contrast, at first require a higher energy expenditure.

As a result, the outlay in terms of energy and apparatus and the thermal stress on the valuable aniline are reduced significantly.

In this way, the rotor sections can be moved with respect to one another with a relatively low outlay of power.

In this way, differing oscillation frequencies in differing scanning directions can be obtained with low expenditure of energy.

This additional energy expenditure and financial investment is intended to increase the yield of methane.

This additional process step requires an additional outlay in terms of apparatus and energy in the production of the pre-alloy.

By means of continuous measurements, they are checking whether the energy required for the circulation operation is viable in the long term.

Lower pressures retard the reaction excessively whilst higher pressures do not accelerate it to an extent which would justify the greater cost of apparatus and greater energy consumption.

In this case it would therefore be necessary, in order to achieve adequate production capacities, to recycle disproportionately large amounts of the extractant, entailing expensive apparatus and high energy consumption.
