Abstract: Natural gas is converted with steam and oxygen in an autothermally operated reactor, and from the reactor a raw synthesis gas with a temperature in the range from 800 to 1200°C is withdrawn. To the cooled, raw synthesis gas a gas rich in H2 is admixed. The synthesis gas with an increased H2 content is converted in a methanol synthesis reactor on a copper catalyst at a pressure in the range from 10 to 150 bar and temperatures from 180 to 350°C. From the synthesis reactor a gas mixture containing methanol vapor is withdrawn, methanol is condensed out, and a cooled residual gas is separated. The residual gas is divided into a first partial stream (recycle gas) and a second partial stream (purge gas).      The recycle gas is admixed to the synthesis gas before the methanol synthesis reactor. The purge gas consists of 30 to 80 vol-% H2, 7 to 35 vol-% CO2 and 3 to 25 vol-% CO. The hourly quantity of purge gas is 8 to 25 % (calculated dry) of the hourly quantity of raw synthesis gas. The purge gas is charged into a separating means, where the gas rich in H2 is recovered, which is admixed to the raw synthesis gas. The hourly quantity of carbon dioxide supplied to the separating means in the purge gas is 10 to 50 % of the hourly quantity of CO2 in the raw synthesis gas.

Filed: 1998-01-30
Granted: 2003-04-01
Abstract: A receiver is provided in which a composite signal is split into two paths. In the first path, a desired signal channel is suppressed by a notch filter. The remaining channels in the composite signal are inverted. In the second path, the signal is delayed to match the delay imposed by the first path. The signal from the first path is recombined with the second path, which reduces the signal level of the undesired channels to the level of quantization noise. The desired signal can then be amplified using the full dynamic range of the amplifier circuitry. If desired, more than one channel may be received at a time. Further, if the two or more channels that are being received have different signal strengths, the digital filtering functions of the notch filter can be used to selectively weight the signals to equalize their strengths. In addition, channels of different bandwidths can be received.

Granted: 2002-03-26
Abstract: In a conventional photo signal amplification transmission system, since control is performed to make constant an output power, total output powers of all wavelengths are made constant when a multi-wavelength transmission is made.          An output power of one wavelength is decreased and deviated from an optimum power.  To solve the problem, a transmission photo amplifier 3, a relay photo amplifier 4 and a receiving photo  amplifier  5  are  provided with  wavelength  number information management sections 11, 12 and 13, respectively.    An amplifying means is controlled in accordance with the number of wavelengths of the multi-wavelength signal which is obtained by the wavelength number information management sections.   The wavelength number  information management sections 11 to 13 multiplex a wavelength number information signal onto an optical fiber cable 6 and renews the signal.
