Скачать или смотреть Residue Upgrading Technology Axens H-Oil

H-Oil in present licensed by Axens - developed by Texaco/HRI:

Ebullated bed reactor suitable for higher CCR / metal feeds, with feed miced with H2, feed upflow the reactor at higher temperature & pressure.

The L-V are separated at the reactor top, liquid is feeding reactor by a pump which achieve aproximative isothermal condition.

After 1st reactor a separator remove vapor from the 2nd reactor feed obtaining higher residence time in the reactor.

H2 is recovered and recycle to process with 3 stages compressor after is passing through high pressure Absorber, membrane, medium pressure Absorber and PSA.

The spent catalyst is on-line daily withdrawn and fresh make-up added eliminating on stream factor.

Conversion is 55-89% and for heavy metal feed has lower CAPEX than fixed bed units.

H-Oil could operate in 4 different modes:

1 reactor at higher LHSV for lower conversion and moderate contaminants removal

moderate/high conversion level provide higher quality products with lower sulfur/contaminants

high conversion mode by bottoms recycle or once through configuration and lower LHSV.

the selectivity could be controled by changing catalyst addition flow rate and process temperature.

Considering the number of licenses, CAPEX & OPEX seems that H-Oil from Axens is the prefered technology for residue conversion!
