Title: Steam reforming of natural gas to hydrogen/nitrogen mixts. - with prior removal of sulphur cpds. by washing with methanol charged with carbon dioxide from the absorption plant
Inventor: BECKER PAUL DIETER DR
IPC: C01B3/50
Filed: 1972-12-30
Abstract: The methanol, opt. contng. an amine additive, used to wash CO2 from the product gas, is used to wash S and/or S cpds. from the natural gas before it enters the reforming process, in which it is first reacted with steam and oxygen under pressure, and the CO formed then reacted with steam to give H2 and CO2. The S cpds., which cause catalyst poisoning in subsequent processing e.g. NH3 synthesis, are removed by a simple and efficient process without high capital costs. Some CO2 is desorbed from the methanol during the natural gas washing, and can be used to give product gas with a high CO/H2 ratio.

Title: Electronic resonance regulator for Peterson coils - automatically sets resonance peak by tuning sweeps and comparison with reference
Inventor: BUCK ROBERT
IPC: H02H9/08
Filed: 1973-11-22
Abstract: The electronic resonance regulator for Peterson coils automatically sets the coil resonance peak, i.e. the maximum voltage at star-coupled coil centre, or adjusts it to a predetermined value. The coil is scanned over its frequency/voltage curve and the resulting output voltages are compared with a preset reference voltage. The tuning sweep stops when the output voltage is the same as the reference voltage. The voltage at the centre of the coil is measured and its rate of change constructed by a differentiator, in order to decide on the direction in which the coil is to be connected. A differential quotient may be formed from the star voltage and the change-over is carried out over a time delay if the quotient is negative.
