The method of the subject matter innovation is used for detecting leaks in pipelines carrying a flowing medium. During the process, the volume flow of the flowing medium is started to be measured at the starting point of the pipe network; examining whether the measured volume flow is greater than a predetermined detection threshold; if the measured flow rate is greater than the detection threshold, the reception time is measured; if the reception time exceeds a predetermined maximum time interval, detecting a leak is recorded and optionally an alarm signal (R1) is generated; in all other cases the operation is considered to be normal. Apparatus for performing the above method comprises a flow meter (1) having a digital output signal and a microprocessor control unit (3) connected to its output. The control unit (3) comprises a sampling unit (3.1) connected with one input to the output of the flow meter (1) and with another input to a signal corresponding to a given lower consumption threshold (Qmin), the output of which is connected to one of the inputs of a timing unit (3.2). The other input of the timing unit (3.2) is connected to a preset signal corresponding to the maximum reception time (t) and its output is connected to the input of an error generating unit (3.3), one output of which is optionally connected to an alarm unit (3.4).

The present invention relates to cocogem surfactants for an enhanced oil recovery process, said surfactants exhibit reduced critical concentration for micelle formation and thermal stability under conditions typical of deeper oil storage layers (e.g. higher temperature, pressure and/or salinity) as compared to the prior art. Furthermore, said cocogem surfactants provide reduced water-to-oil interfacial tension as compared to the prior art. The invention also relates to a process for producing said cocogem surfactants.

The present invention relates to a process for the production of artificial mineral oil containing hydrocarbon fractions having high octane and cetane number, which is produced mainly by environmentally friendly catalytic cracking of plastic wastes containing mainly polyolefins under mild conditions on a specially activated catalyst. The invention relates to the specially activated catalyst and to the activation process of the catalyst.

The present invention relates to a technology that is capable of the recovery of plastic waste and other plastic by-products by thermal decomposition, becoming increasingly important for the protection of the environment, by the application of a high-throughput, continuous operation mixed film reactor, and cracking process for converting moderately contaminated polyolefin and polystyrene-based plastic wastes into suitable raw material that can be used directly for the refining process of producing synthetic oil. The further recovery of plastic waste and other plastic by-products by thermal decomposition is becoming increasingly important for the protection of the environment.
