  • Device and method for distributing a fluid in an industrial facility
    Patent number: 11543837
    Abstract: The invention can include a device and method for distributing a fluid in an industrial facility that comprises a fluid distribution pipe, a discharge pipe, a distribution valve that is positioned on the distribution pipe and controlling the distribution of fluid between an upstream area and a downstream area, a discharge valve positioned on the discharge pipe, and measuring means for measuring, in real time, a characteristic parameter of the distribution of the fluid within one of the pipes. A module is also included for calculating a sliding threshold value of the characteristic parameter and means configured to control the partial gradual opening or closing of the discharge valve depending on the result of the comparison of said sliding threshold value with an instantaneous value of the characteristic parameter, in order to improve reliability of the industrial facility.

  • Purification of an H/CO mixture with lead control of the regeneration heater
    Patent number: 8167977
    Abstract: A method of purifying a gaseous mixture rich in hydrogen and in carbon monoxide, commonly termed an H2/CO mixture or syngas, by adsorption prior to treating it cryogenically with a view to producing a CO-rich fraction, and/or one or more H2/CO mixtures of determined content, such as a mixture of 50 mol % H2/50 mol % CO and generally a hydrogen-rich fraction is provided.
