How are different types of naphtha cargoes classified for reporting purposes? (7/27/2004) Q. On the EIA-800 Survey,- What do I include in Product Code 001? (7/30/2010) Answers: Q: Is natural gas feedstock for hydrogen production included when reporting natural gas quantity used as fuel (EIA product Code 105) on the EIA 820? A: Exclude natural gas feedstock for hydrogen production under Code 105 on EIA 820. Report only the quantity of natural gas consumed as fuel at the refinery. Report natural gas used for hydrogen production under Code 107. Q: On the EIA-810 survey, where is hydrogen reported? A: Report receipts and inputs of hydrogen as "Hydrogen" (line 091). Quantities reported by refiners on line 091 include hydrogen produced from hydrogen plants located at refineries and hydrogen purchased from third-party suppliers. Q: On the EIA-810 survey, where are feedstock inputs for hydrogen production reported? A: Feedstock inputs for hydrogen production are not reported on the EIA-810. See the question "How should I report still gas and naphtha on the EIA-810 when these products are used as hydrogen plant feedstock?" for further information. Q: How should I report still gas and naphtha on the EIA-810 when these products are used as hydrogen plant feedstock? A: Report still gas (line 045), special naphtha (line 051), and unfinished oil, naphtha and lighter (line 820) as shipments to a hydrogen plant when these products are used as hydrogen feedstock. Report any feedstock return streams from a hydrogen plant as receipts from the hydrogen plant and inputs at the refinery. Q: On the EIA-810 survey, concerning product Code 091, "Hydrogen," how do I convert standard cubic feet of hydrogen to barrels? A: The conversion factor is 19,426 standard cubic feet per barrel of fuel oil equivalent. So, when you divide the number of standard cubic feet of hydrogen by 19,426, your result will be in barrels. Q: On the EIA-810 survey, normal butane and isobutane each have 2 lines available for reporting, one labeled NGPL and one labeled LRG. How do I determine where on Form EIA-810 to report these products? A: Normal Butane -NGPL (code 249) and Isobutane -NGPL (Code 247) are products of natural gas processing plants and are usually called natural gas plant liquids (NGPL). Natural gas plant liquids originate at natural gas processing plants where the ethane and heavier hydrocarbons are separated from natural gas. Normal butane, isobutane, and pentanes plus are often received and input at refineries for blending and for use in certain refining processes such as alkylation. Ethane and propane from natural gas processing plants are not normally input to refinery process units or blending operations and because historically no refiners have reported input of NGPL ethane or propane on Form EIA-810 these products have been eliminated from the form.
- 631 for ethylene - 642 for propane - 632 for propylene - 643 for normal butane - 633 for butylene - 644 for isobutane, and - 634 for isobutylene Sometimes it is unknown whether the butane or isobutane is NGPL or LRG. Also, products of natural gas processing plants are often commingled with liquefied refinery gases in storage. For this reason we combined the NGPL, LRG and Olefins and created a product Code for the total. These include:
-246 for propane/propylene -244 for butane/butylene -245 for isobutane/isobutylene Fractionating plants used for separating mixed NGPL products are considered outside of refineries for purposes of EIA-810 reporting. This is true even when a fractionation plant is physically located within a refinery. Exclude input of mixed NGPL products and production of fractionated NGPL products from EIA-810 reporting. Operators of fractionation plants report inventory on Form EIA-816 "Monthly Natural Gas Liquids Report". Q: The definition of still gas in the EIA glossary identifies principle constituents as methane, ethane, ethylene, normal butane, butylene, propane, propylene, etc." The products listed include several that are listed elsewhere under separate product Codes as liquefied refinery gases. How do I determine whether to report a product as liquefied refinery gas or still gas? A: Still gas, (product Code 045) reported on the EIA-810 survey, includes methane as well as products otherwise identified on the form as liquefied refinery gases (LRG). The product Codes for liquefied refinery gases are:
- 631 for ethylene - 642 for propane - 632 for propylene - 643 for normal butane - 633 for butylene - 644 for isobutane, and - 634 for isobutylene The usual difference between still gas and LRG is that liquefied refinery gases are fractionated or at least identified as separate products based on chemical analysis, while still gas is unfractionated. LRG products may be used as refinery fuel, or they may be shipped outside the refinery for use as fuel or input for chemical plants. Still gas is normally used as refinery fuel, though still gas may also be shipped to chemical plants or hydrogen plants. Reports on the EIA-810 survey for refineries where still gas is used only as fuel typically show production equal to fuel use and loss with zero receipts, inputs, and shipments. Still gas may be shipped to petrochemical or hydrogen plants, where plant operators extract parts of the still gas stream needed for their operations. The remainder of the still gas may be returned to the producing refinery. The return stream is reported on line 045 in the "receipt" and "input" columns, and then under "production" and "fuel use and loss" when it enters the refinery fuel system. It is often the case that known quantities are still gas receipts, shipments, and fuel use and loss. In this case, input is assumed equal to receipts. Production is the balancing item for the line such that (receipts - inputs + production - shipments - fuel use and loss = 0). Q: On the EIA-810 survey, concerning product Code 097 "Miscellaneous Products: Non-Fuel Use," how do I convert short tons of sulfur to barrels? A: The conversion factor is 3.17 barrels per short ton. So, when you multiply the number of short tons by 3.17, your result will be in barrels. Q: On the EIA-810 survey, concerning Product Codes 820 through 850 - How can I calculate the net input or net production for these products? A: Product Codes 820 - 850 are the four breakouts of product Code 812 (Unfinished Oils). You should report either the (net) input or (net) production for each of these four unfinished oil breakouts. One way to determine the net input or net production of product Codes 820 - 850 is to use the calculation shown below. Your ability to use this method depends on whether you are able to measure the beginning and ending inventory level, receipts, shipments, and fuel use & loss volumes for each of the four unfinished oil breakouts. This calculation derives either a net input value or net production value and is based on the material balance equation where: Beginning stocks plus receipts, minus input, plus production, minus shipments, minus fuel use & losses, equal ending stocks.
Receipts were "50" Shipments were "35" Fuel Use and Losses were "0" Ending Stocks (ES) were "200"
Receipts +50 Shipments -35 ES -200 Equals -80 Q: How are different types of naphtha cargoes classified for reporting purposes? A: Naphtha that will be used as reformer feed is classified as unfinished oils, naphtha and lighter (EIA product Code 820). Naphtha intended for gasoline blending is classified as motor gasoline blending components. If the naphtha is intended for gasoline blending but it's not already blended to form RBOB (EIA product Code 118), CBOB (EIA product Code 139), or GTAB (EIA product Code 117), then it is classified as All Other Motor Gasoline Blending Components (EIA product Code 138). Q: On the EIA-800 Survey,- What do I include in Product Code 001? A: The total inputs line on Form EIA-800 should include the following.
Inputs of Natural Gas Plant Liquids Inputs of Hydrogen Inputs of Other Hydrocarbons Inputs of Renewable Fuels (Including fuel ethanol) Inputs of Oxygenates (including ETBE, MTBE, etc.) Net Inputs of Unfinished Oils Net Inputs of Motor Gasoline Blending Components (Codes 117, 118, 138, 139) Net Inputs of Aviation Gasoline Blending Components (Code 112 on Form EIA 810) 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. Total input may be less than crude oil input and gross input to atmospheric crude oil distillation in cases where production of unfinished oils and/or gasoline blending components exceed input. Q: Product Code 050 - Only crude oil charged to the crude tower that goes to fuels units, not chemical units? Does that mean that we need to back off any i.e. naphtha that was used to charge chemical units and add back in the chemicals that were blended? A: The instructions concerning inputs for making finished petrochemicals are intended to exclude any inputs (crude oil or otherwise) that went into the production of petrochemicals where the chemical products would not be reported on Form EIA 810 "Monthly Refinery Report". For example, suppose you were running crude oil and producing naphtha for petrochemical feedstock use (Code 822 on Form EIA 810). You would report inputs of crude oil for producing petrochemical feedstocks. However, you would not report inputs of the naphtha chemical feedstocks when they were cracked into ethylene at a nearby chemical plant because the ethylene would not be reported as production on your refinery report. In general, every input reported has to have a corresponding production in order to make the processing gain/loss balance out correctly on the monthly EIA-810 survey. Naturally, your weekly reports on Form EIA-800 will never really balance because not all of your production can be reported since we only ask for selected "major" products. |
