    摘要： The invention relates to the optimized management of one or more fluid production units, especially those involving fluid separation treatment, comprising: a) a data collection step, the data being on one or more values of current parameters defining a current operating point of the production unit, on a future production demand and on at least one optimization criterion; and b) a computation step for computing one or more parameters defining a new operating point of the unit, at least in accordance with this demand. The computation step b) comprises at least: 1) an estimation of at least one optimum solution for defining the new operating point; and 2) a validity test carried out on this optimum solution, at least in accordance with an analysis of the transition of the production unit from the current operating point to the new operating point.

    摘要： The invention relates to a device for pumping a cryogenic fluid, consisting of a tank for storing a cryogenic fluid containing cryogenic liquid, a cryogenic pump having an inlet pressure loss, and a suction line connecting the tank to the pump, said pumping device including a system for controlling the pressure in the tank for selectively maintaining said pressure at least equal to the saturation pressure of the stored cryogenic fluid plus the inlet pressure loss of the cryogenic pump and optionally plus the value of the pressure losses owing to the pipes forming the suction line connecting the tank to the pump. The invention is characterized in that the pressure-control system includes a duct connecting a high-pressure outlet of the pump to the tank for selectively returning the pumped cold fluid to the tank, said duct including an expansion valve for returning cold gas to the tank.

    摘要： An apparatus for decreasing steam methane reformer (SMR) tube temperature is provided. The apparatus can include an SMR furnace, a monitoring system in communication with the SMR furnace and a water source in fluid communication with the SMR furnace. The SMR furnace includes a plurality of SMR tubes disposed within the SMR furnace. The monitoring system is configured to monitor the temperature of at least a plurality of SMR tubes and compare the temperature against a first predetermined value, and the water source is configured to introduce water to an SMR tube that has a temperature above the first predetermined value, such that the temperature of the SMR tube is reduced.
