Abstract: A recycling and recovery system and process comprising a flash gas separator that receives a slurry comprising liquid medium and solid polymer particles. The flash gas separator separates the diluent from the solid polymer particles as a vapor stream comprising at least diluent and heavies. A line receives the vapor stream from the flash gas separator. The line leads to a heavies removal system that yields a liquid that is relatively concentrated in heavies and a diluent vapor that is relatively free of heavies. The liquid is passed to a heavies column, while the diluent vapor is passed to a diluent recycle chamber and then recycled to a slurry polymerization reactor without additional treatment to remove heavies.

Abstract: A fuel processor apparatus comprising a catalytic tubular reactor is heated using an infrared radiant burner to provide the endothermic heat of reaction needed to reform a mixture of hydrocarbon and steam for the production of a hydrogen-rich gas stream. The hydrogen-rich gas stream is further purified using a sequence of catalytic steps that is fed to a fuel cell whereupon a portion of the hydrogen contained in the gas stream is consumed for the production of electricity by electrochemical reaction with oxygen. An unused portion of the purified hydrogen-rich gas stream exits the fuel cell stack and is combusted in the infrared radiant burner. A fuel cell control system rapidly responds to a variable fuel cell electric demand by adjusting the feed of hydrocarbon to the catalytic tubular reactor to maintain the surface temperature of the infrared radiant burner within defined limits.
