The present invention relates a steam methane reformer tube outlet assembly and a method of assembling or retrofitting same. More specifically, it relates to an exposed flanged tube outlet of a reformer designed to mitigate metal dusting corrosion, dew point condensation-related metal fatigue and cracking, and over-temperature induced metal failures such as hydrogen attack.

The invention relates to a process for producing superabsorbents, comprising the preparation of partly neutralized acrylic acid by the steps (i) preparing an over-neutralized acrylic acid having a degree of neutralization of at least 100.1 mol-% by mixing of an acrylic acid 1 and a base and (ii) preparing a neutralized acrylic acid having a degree of neutralization from 50 to 85 mol-% by mixing of the over-neutralized acrylic acid and an acrylic acid 2, wherein the content of dimeric acrylic acid in the acrylic acid 2 is lower than the content of dimeric acrylic acid in the acrylic acid 1.

A box style steam methane reformer has plural sections, with each section having walls forming an interior cavity and open ends that communicate with the interior cavity. Each section has a feedstock supply pipe and a fuel supply pipe located along the top wall, as well as a syngas collection pipe and a flue gas collection duct located outside of the bottom wall. The pipes and ducts have ends that are aligned with each other to allow the sections to be assembled together. Burners are located in the interior cavity and are connected to the fuel supply pipe. Reactor tubes extend through the interior cavity. The bottom ends are supported by the syngas collection pipe and the top ends are spring supported to allow for expansion and contraction. Refractory members are located in the interior cavity and across a slot leading to the flue gas collection dust. The spacing between the refractory members varies to control the flow of flue gas.

A heat shield bladder includes first and second sheets of insulating material that form a bladder between the first and second sheets. At least one reflective foil is disposed within the bladder and a plurality of spacers are disposed within the bladder and positioned to space the at least one reflective foil from the first and second sheets of insulating material. Multiple reflective foils may be disposed within the bladder with spacers between each reflective foil. The heat shield bladder may be rolled into a tube shaped and used inside a pipe or formed into panels that may be used to line a vessel.

A structured body for heating system for carrying out heating of a pressurized feed gas is provided, where the heat is provided by resistance heating by means of electrical power.

A dual vessel reactor and a method of carrying out a reaction using a dual vessel reactor are provided using a non-condensable gas to substantially isolate the inner vessel from the outer vessel during the reaction and limit the heating of the outer vessel when steam from the inner vessel condenses on the interior surface of the outer vessel. By limiting the heating of the outer vessel through the condensation of the steam or other vapor from the inner vessel, the operating temperature of the outer vessel is kept below an upper threshold of the operating temperature of a seal used to seal the door in the outer vessel.

A reactor system and a process for carrying out the ammonia cracking reaction of a feed gas comprising ammonia to hydrogen are provided, where the heat for the endothermic ammonia cracking reaction is provided by resistance heating.

An apparatus with at least two thermal zones of different temperatures, each thermally isolated from the other. A stream of ambient air is used to isolate the two zones. A housing can have a dual wall construction defining an air conduit between the two walls, above, below and/or around the sides. An exothermic device can be mounted within the housing. In operation, a blower within the housing draws air into the air conduit at the rear of the housing. The intake air flows around the housing, then into the exothermic device. A cool zone can be located within the housing, upstream from the blower, kept cool by the flow of ambient air. A hot zone can exist downstream from the blower. A third zone of intermediate temperature can be located downstream from the blower, upstream from the device. The exothermic device can be physically isolated from the cool zone by the blower and an insulated wall on which the blower can be mounted. The ambient air fed to the hot zone can be the source of oxygen for the exothermic device.

A gas separation process in which the thermal storage of the heat in the gas is desired as well as the gas separation. This invention outlines a novel process and system whereby the thermal storage efficiency can be vastly increased by matching the gas sorption fronts and the thermal fronts to cause thermal front sharpening. The gas separation process and system include an adsorption vessel having an adsorbent in an amount of 10-40% and a thermal storage component in an amount of 50-90% by volume.

Induction heating is applied to thermochemical processes in specially adapted chemical processing units comprising heat exchange channels. Collections of components are housed in portable units adapted for easy setup and maintenance.
