Industry Glossary

The definitions contained in this "Chemical Glossary" are merely generic definitions that may prove helpful to those using this Web site. They do not supercede, nor are they intended to supercede, the definitions or specifications that may apply to various technical terms as they are used in specific Chevron Phillips Chemical documents, agreements, proposals or offerings, or in Chevron Phillips Chemical or third party patents.

Racing Fuels Chevron Phillips Chemical’s proprietary racing fuel for high-performance engines such as NASCAR racecars, trucks, motorcycles, ATVs, boats, jet skis and snowmobiles.  Racing Fuels are 100% petroleum derived hydrocarbons and contain detergent additives, corrosion inhibitors, and antioxidant additives that are added in concentrations similar to those found in commercial fuels.
Reactive A chemical which in the pure state, or as produced or transported, will vigorously polymerize, oligomerize, oxidize, decompose, condense, or will otherwise be readily converted to another material if contacted with a second reagent, or if conditions are suitable to sustain a reaction (including shock, pressure or temperature). 
Reference fuels

Chevron Phillips Chemical reference fuels help establish the quality of transportation vehicle fuels in standardized test procedures. The company  supplies a broad range of reference fuels and fluids, including primary and secondary standards for gasoline, diesel, and aviation fuel. It also supplies a variety of test fluids used as reagents in various ASTM, SAE, and MilSpec tests.

Refinery

An installation that manufactures finished petroleum products from crude oil, unfinished oils, natural gas liquids, other hydrocarbons, and oxygenates.

Refinery Input

The raw materials and intermediate materials processed at refineries to produce finished petroleum products. They include crude oil, products of natural gas processing plants, unfinished oils, other hydrocarbons and oxygenates, motor gasoline and aviation gasoline blending components and finished petroleum products.

Refinery Production

Petroleum products produced at a refinery or blending plant. Published production of these products equals refinery production minus refinery input. Negative production will occur when the amount of a product produced during the month is less than the amount of that same product that is reprocessed (input) or reclassified to become another product during the same month. Refinery production of unfinished oils, and motor and aviation gasoline blending components appear on a net basis under refinery input.

Refinery Yield

Refinery yield (expressed as a percentage) represents the percent of finished product produced from input of crude oil and net input of unfinished oils. It is calculated by dividing the sum of crude oil and net unfinished input into the individual net production of finished products. Before calculating the yield for finished motor gasoline, the input of natural gas liquids, other hydrocarbons and oxygenates, and net input of motor gasoline blending components must be subtracted from the net production of finished motor gasoline. Before calculating the yield for finished aviation gasoline, input of aviation gasoline blending components must be subtracted from the net production of finished aviation gasoline.

Reformate

A mixed composition stream produced by a catalytic or thermal reformer. Reformate is a feedstock for benzene and xylenes.

Renewable Diesel Fuel

Diesel fuel and diesel fuel blending components produced from renewable sources that are coprocessed with petroleum feedstocks and meet requirements of advanced biofuels.

Renewable Fuels

Fuels and fuel blending components, except biomass-based diesel fuel, renewable diesel fuel, and fuel ethanol, produced from renewable biomass.

Residual Fuel Oil A general classification for the heavier oils, known as No. 5 and No. 6 fuel oils, that remain after the distillate fuel oils and lighter hydrocarbons are distilled away in refinery operations. It conforms to ASTM Specifications D 396 and D 975 and Federal Specification VV-F-815C. No. 5, a residual fuel oil of medium viscosity, is also known as Navy Special and is defined in Military Specification MIL-F-859E, including Amendment 2 (NATO Symbol F-770). It is used in steam-powered vessels in government service and inshore power plants. No. 6 fuel oil includes Bunker C fuel oil and is used for the production of electric power, space heating, vessel bunkering, and various industrial purposes.
Residuum Residue from crude oil after distilling off all but the heaviest components, with a boiling range greater than 1000 degrees Fahrenheit.
Road Oil Any heavy petroleum oil, including residual asphaltic oil used as a dust palliative and surface treatment on roads and highways. It is generally produced in six grades from 0, the most liquid, to 5, the most viscous.
Rotational molding

A high-temperature, low-pressure process used to form hollow parts through the application of heat to biaxially rotated molds. Articles manufactured this way include recreational equipment and storage tanks for agriculture, industrial chemicals or waste.
