may not necessarily mean low investment requirements in the region, since part of the<br />

outdated facilities will require replacements or substantial investments to modernize,<br />

which could also lead to more capacity being added than indicated.<br />

Despite projected demand increases for refined products in Africa of 1.8 mb/d between<br />

2011 and 2035, current firm construction in the region is modest – 0.3 mb/d by<br />

2016 – and total expansion by 2035 is projected to be 0.9 mb/d, roughly only half of<br />

the anticipated demand increase. Rising utilizations also contribute to meeting demand<br />

growth, but product imports are projected to remain a major factor in the region’s<br />

total product supply. Africa has the benefit of growing domestic/regional crude oil<br />

production, which is mainly of good quality, for refinery feedstock. Against this, many<br />

of the refineries in the region face challenges of being small scale, relatively old, low<br />

in complexity, low in energy efficiency and historically poor in terms of utilizations.<br />

In addition, there is intense and growing competition to supply product imports into<br />

Africa from Europe, the Middle East, India and the US. These factors lead to an outlook<br />

wherein regional refinery expansions struggle to compete with product imports.<br />

Conversion and desulphurization capacity additions<br />

Sufficient distillation capacity is a necessary pre-condition for the adequate functioning<br />

of the refining sector. Supporting conversion and product quality related capacity<br />

play vital roles in processing raw crude fractions into increasingly advanced finished<br />

products – and they deliver most of a refinery’s ‘value added’. The importance of these<br />

secondary processes has been increasing with a general trend toward lighter products<br />

and more stringent quality specifications. Essentially all major new refinery projects<br />

comprise complex facilities with high levels of upgrading, desulphurization and related<br />

secondary processing. It means they have the ability to produce high yields of<br />

light clean products which, almost invariably, can be produced to the most advanced<br />

specifications (such as Euro V standard).<br />

In addition, many new refineries are being designed with the ability to process<br />

heavy, low quality, and often high acid number (high TAN) crudes, as well as better<br />

quality grades and/or to produce petrochemical feedstocks such as propylene and aromatics.<br />

Smaller projects in existing refineries are generally directed toward the same<br />

aims. Together, these factors are leading to high levels of secondary processing capacity<br />

additions and associated progressive increases in the proportions of secondary capacity<br />

per barrel of distillation.<br />

Results and projections for secondary processing to 2035 are presented in<br />

Table 7.3 and Figures 7.4–7.7. In respect to conversion capacity, these projections<br />

emphasize a sustained need for incremental hydro-cracking, which constitutes almost
