Naphtha classified as unfinished oil or motor gasoline blending components must have an associated processing facility when it is reported as being imported. The processing facility is either a refinery or a blending terminal where the naphtha will be processed or blended to produce finished gasoline or other finished products.

In addition to unfinished oils and motor gasoline blending components, naphtha may fall into one of two additional product categories depending on intended end use. One product is special naphtha (EIA product code 051). Special naphtha is the classification to use for naphtha that is intended for use as solvent. Another possible classification for naphtha is petrochemical feedstock (EIA product code 822). This would be the correct product classification for naphtha intended for cracking into olefins.

The total inputs line on Form EIA-800 should include the following.

Inputs of Crude Oil
Inputs of Natural Gas Plant Liquids
Inputs of Other Hydrocarbons, Hydrogen, and Oxygenates (including fuel ethanol, MTBE, etc.)
Net Inputs of Unfinished Oils
Net Inputs of Motor Gasoline Blending Components (codes 122,123,139,120,121,138)
Net Inputs of Aviation Gasoline Blending Components (code 112 on Form EIA-810)

Refineries will typically report negative net reruns of RBOB and CBOB (codes 122, 123, and 139) because these are shipped out of the refineries to terminals where they are blended with fuel ethanol or in some cases MTBE. It's unlikely that Gasoline Treated as Blendstock (codes 120 and 121) would be present at most refineries because it is imported product typically blended at terminals. All other motor gasoline blending components (code 138) could be shipped out of a refinery for blending elsewhere in which case the net reruns would be negative (production greater than inputs). If a refinery received all other motor gasoline blending components from another facility then net reruns would be positive (inputs greater than production). A refinery that neither receives nor ships significant volumes of all other motor gasoline blending components would generally have a rough balance of inputs and production with small volumes of net reruns resulting mostly from changes in inventory. In the balanced case, a refinery would have either positive or negative net reruns in any given week depending on the inventory situation.

Naturally, there are circumstances, such as a shut down of crude oil processing, where a refinery that normally has a rough balance of input and production for all other motor gasoline blending components might show significant net inputs from inventory. After returning to normal crude processing, the same refinery would likely show large negative net reruns (i.e. net production) of motor gasoline blending components as inventory was replenished.

Gross inputs reported on line 990 are used for calculating the utilization rate of your atmospheric crude oil distillation unit. The 990 inputs should include all the barrels of crude oil and other petroleum (unfinished oils etc.) input to your atmospheric crude unit. Since this number is only used for calculating the crude unit utilization rate, it also includes barrels that go through the unit more than one time during the reporting period. This is because every barrel counts against capacity for utilization purposes no matter how many times it goes through the unit. This is different from crude oil inputs because the crude oil input number is only telling us how much crude oil was used to produce the various product outputs from the refinery. The crude oil may be processed more than once in the various units, but in the case of crude inputs we just want to know how much was input to the refinery and not every time it went through a unit.

In general, gross inputs are expected to be greater than crude inputs because gross inputs include things other than crude oil as well as any re-runs of the same barrels through the atmospheric crude unit. However, some refineries run crude oil directly to their vacuum distillation or other units. In this case, there would be crude oil that never goes through the atmospheric crude unit. If enough crude oil bypassed the atmospheric crude unit then it would be possible for crude inputs to exceed gross inputs to atmospheric crude units. Obviously, gross inputs on line 990 also are quite different from total inputs. Back to Top
