This may lead to the system becoming unable to function and thus to the switching off of the unit.

This can, for example, be achieved through a fail-safe switching off of the monitored installation.

Stopping and shutting down the installation can thus be prevented at times.

A possible reaction can be an orderly shutdown of the plant.

In particular, a shutdown of the plant is acceptable only under certain exceptional conditions.

Major fault alarm (leads to the system being switched off)

It can lead to monitoring the current and to power-off of the system.

Finally, they also serve for drying the system after shut down.

Taking the separators out leads to immediate deativation of the plant.

The deactivation of the plant is controlled by:

When shutting down part of the power plant, its staff will face new challenges.

This signal can preferably be used to drive a switching element for shutdown of the technical installation.

The project will also study complex scenarios such as start-up and shut-down.

They shall also be used during plant start-up and shut-down operations in order to ensure that the abovementioned minimum temperature is maintained at all times during these operations and as long as the waste is in the combustion chamber.

Such burners shall also be used during plant start-up or shut-down operations in order to ensure that the relevant minimum temperature is maintained while unburnt waste is in the combustion chamber.

Even where automatic shutdown systems are available it is usually necessary for operator intervention to ensure safety for an appreciable interval following the shut­down.

The required amount of air can no longer be fed through with the blowers generally employed, and the conversion of the plant falls; this forces a premature shutdown of the plant in order to replace the catalyst.

A further substantial advantage of the concept according to the invention may be seen in that by virtue of the parallel flow principle, in the case of failure of one of several treatment zones the remaining treatment zones can still be operated, whereas in the known construction such an event compels shutdown of the entire plant.

Furthermore, a monitoring and regulating unit can be connected to the pulse generator so that chance of short circuits or impermissibly high currents or voltages can be recognized at once and result in shutting down the apparatus.

In the event of failure of a sub-switching matrix the decoder can correctly restore the data words. It therefore is possible to effet repair simply replacing the defective sub-switching matrix without switching-off the exchange.

Residual dust remains as a dust deposit in the heat exchanger tubes after the unit has been switched off, because there is no self-cleaning due to the force of gravity of the horizontal tubes.

It is an object of the present invention to improve the above-described process of EP 244 632 B1 (incorporated herein by reference) for continuous industrial production of unsaturated aliphatic aldehydes by oxidative dehydrogenation of the corresponding alcohols with an oxygen-comprising gas over a supported catalyst consisting of copper, silver and/or gold on an inert support in a tube bundle reactor, rapid cooling of the reaction gases and removal of the aldehydes from the resulting condensate to the effect that the prior art disadvantages no longer arise, ie. that the continuous process can be operated for long periods, ideally for periods extending over several years, without shutdown of the plant and without costly drilling out of the reaction tubes in a readily manufacturable reactor. BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1A, 1B, 1C illustrate various embodiments of the invention.

Due to the vertical or greatly sloped arrangement of the heat exchangers, the force of gravity of the dust particles causes during the operation and after the switching off of the heat exchanger unit that no residual dust can solidify and bake on in the heat exchanger tubes.

Otherwise, morphology problems with the polymer (lumps, deposits on walls, blockages in lines or heat exchangers) can occur and force shutdown of the plant.

In accordance with the invention, free from residues is understood to be a process which avoids the formation of deposits in the reactor space and thus makes it superfluous to shut down the plant for removing the deposits, so that a continuous operation is ensured.

Particularly when the unit is suddenly shut down, as for example when there is a power failure, or an interruption of control air for the pneumatically operated devices etc., all retentate conduits of the cross flow filtration system must be flushed out as quickly as possible.

The result may be what is called a hot spot which might impose a shut-down of the entire plant.

In the event of an unscheduled shut-down of the unit, resulting from either automatic or inadvertent actuation of an emergency-switch or some other power switch, the spraying process is interrupted almost immediately.

Therefore, the system must be monitored for overcurrent in order to protect the inverter by shutting down the system or by some other intervention into the inverter control.

If the pressure is reduced abruptly after shutting down the system, i.e. after the standstill of the expansion machine 30, the working substance dissolved in the oil evaporates.
