Final UN annex records Lavan topping-plant shutdown days after two attacks

The annex recorded two wartime attacks on Tehran Refinery and 247 days of lost productive capacity. Repairs followed each attack; this cumulative interruption measure is separate from throughput...

Seven wartime attacks on Esfahan Refinery caused 364 lost operating days, the annex reported. Reconstruction proceeded after attacks, but some temporary repairs still needed permanent correction at...

Tabriz Refinery endured 14 wartime attacks and 238 days of lost production, the annex reported. The mission suggested mountainous terrain and relative inaccessibility probably reduced the frequency of...

The annex recorded four reported attacks on Shiraz Refinery and 165 days of lost production. It associated fewer attacks with distance from war activity, while recognizing the refinery and neighboring...

The annex recorded 1,400 lost production days at Bakhtaran Refinery. It stated that the plant was completely shut during 1981 and 1982 because its crude-supply pipeline had been destroyed, linking...

The annex warned that restored refinery capacity still relied on instruments, controls and equipment ten to fifteen years old. Production recovery therefore coexisted with technological and efficiency...

The mission found refinery saleable yields of 94–96 percent broadly average for the industry. It assessed this performance measure separately from throughput, fuel use, product mix and losses.

The mission was informed that refinery weight losses approached 0.5 percent and judged this unsatisfactory. The annex treated these losses as a performance concern rather than assuming restored output...

From limited data, refinery fuel consumption appeared above average to the mission. It observed little energy-conservation equipment and connected this shortcoming with binding financial constraints.

The mission considered Iran’s refinery light-oil to heavy-oil ratio too low while gasoline, kerosene and diesel were imported at high cost. It recommended reexamining refinery configurations, rather...
