Abstract: Water saturated molecular sieve in a gas dehydration unit is regenerated. A short loop is used in which regeneration gas is recycled to a heater upstream of a vessel in regeneration mode. The regeneration gas passes over the molecular sieve in the vessel to desorb water thereby regenerating the molecular sieve. The short loop also includes a condenser, a water separator and a compressor. The regeneration gas is not recycled to the AGRU at the front-end of the plant, thus the regeneration gas flow rate can be increased, as it is not limited by the front-end capacity of the plant. Moreover, the pressure of the system during regeneration can be reduced within the limits of system hydraulics. By using the short loop, the total time required for regeneration can also be reduced. The embodiments disclosed can de-bottleneck molecular sieve regeneration constraints in LNG, LPG or cryogenic gas plants.

Abstract: Reforming exchangers for syngas production are provided. The reforming exchangers can have a shell-and-tube configuration and include a shift catalyst on the shell side of the exchanger to reduce a carbon monoxide concentration in a shell side product gas mixture. Processes for forming syngas using the reforming exchangers are also provided.
