Hydroprocessing option

Table 7 also shows these hydrogen requirements as 0.21 Quad/year in 1980 and 0.46 Quad/year in the year 2000 (coking option) or 1.41 Quad/year (hydroprocessing option). Assuming these quantities of hydrogen are produced by steam reforming, the reformer feed stock requirements would increase from 149 thousand B/D crude oil equivalent in 1980 to 326 thousand B/D in the year 2000 option) or 1001 thousand B/D for the year... 

Marathon s strategy was to leverage future clean fuels projects to minimize capital investment and maximize emission reductions. Units with feed hydrotreating capacity typically used catalyst additives. Units with no hydroprocessing typically relied upon other technology options in conjunction with catalyst additives. Since each application was unique, implementation was required over a period of time. Figure 14.5 shows the timeline when significant events occur for the Marathon CD. 

Another processing option involves the use of solvent deasphalting (SDA) to treat the vacuum residuum prior to hydroprocessing (Hung etal.,... 

A fuel gas long situation also provides the opportunity to recover valuable products from the fuel gas. For example, a refinery plant might consider recovery of hydrogen from a hydroprocessing gas source. Options for H2 recovery include pressure swing adsorption (PSA) and membrane systems based on the H2 purity requirement. Alternatively, ethane and ethylene could be recovered from certain fuel...
