A method to control the cooldown of main heat exchangers in liquefied natural gas plant. The method provides for the automated control of a flow rate of a natural gas feed stream through a heat exchanger based on one or more process variables and set points. The flow rate of refrigerant streams through the heat exchanger is controlled by different process variables and set points, and is controlled independently of the flow rate of the natural gas feed stream.

Method to control the cooldown of main heat exchangers in liquefied natural gas plant

The present invention relates to reactor tubes packed with a catalyst system employed to deliberately bias process gas flow toward the hot tube segment and away from the cold segment in order to reduce the circumferential tube temperature variation.

Reactor packing with preferential flow catalyst

A top-fired reformer box is provided. The top-fired reformer box includes a burner row, a tube row, a reformer tunnel including a closed end, an open end, and a plurality of tunnel ports formed along a side wall of the reformer tunnel, the plurality of tunnel ports including a one or more tunnel port located along the side of the tunnel, and a flow resistor positioned at least one tunnel port applying a flow resistance for flue gas entering the reformer tunnel via the at least one tunnel port such that uniform flow is achieved within the reformer tunnel.

Reformer box with reformer tunnel including tunnel port

Steam-hydrocarbon reforming reactor with a reformer tube containing ceramic-supported catalyst pellets and metal foam particles. The ceramic-supported catalyst pellets have a porous support comprising one or more of alumina, calcium aluminate, and magnesium aluminate. The metal foam particles comprise Fe and/or Ni. The ceramic-supported catalyst pellets and metal foam particles may be layered or interspersed.

Steam-hydrocarbon reforming reactor

An adsorption vessel comprising a packed bed region of adsorbent particles contiguously arranged, comprising a perforated adsorbent particles, a gas separation process using the perforated adsorbent particles, and methods for making the perforated adsorbent particles. The perforated adsorbent particles each comprise an adsorbent material where the perforated adsorbent particles each have at least 10 channels extending through the particle. The equivalent diameter of the channels may range from 0.05 mm to 1.5 mm, and the void fraction of the channels may range from 0.05 to 0.5.

Perforated adsorbent particles

A tubular reactor for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert with cup-shaped structures having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.
