fuel classification

Taking data from here:

https://deq.nc.gov/about/divisions/waste-management/waste-management-rules-data/underground-storage-tanks-databases

I'd like to map these:

Diesel
Fuel Oil
Gasoline, Aviation
Gasoline, Gas Mix
Gear/Lube Oil
Heating Oil/Fuel
Hydraulic Fluid
Kerosene, Aviation
Kerosene, Kero Mix
LP/Propane Gas
Mineral Oil
Motor Oil
Natural Gas
Oil, New/Used/Mix
Other, Hazardous
Other, Non-Petroleum
Other, Petroleum
Petroleum
Transmission Fluid
Unknown

Materials Branch

We have:

• ENVO:00002985 ! oil *
  • ENVO:00002983 ! fuel oil
    • ENVO:01000551 ! paraffin
  • ENVO:00003903 ! aviation fuel
  • ENVO:00002984 ! petroleum
    • ENVO:01000460 ! asphalt

Note that "oil" is defined generically (A viscous liquid state at ambient temperatures or slightly warmer, and is both hydrophobic and lipophilic) and could encompass e.g. olive oil from FoodOn.

Is the classification of paraffin correct?

"fuel oil" is undefined

"aviation fuel" seems a bit random. Undefined. Is this intended to be defined by role (e.g. any fuel used in aviation?). I think it is better to define this (and relabel) as "jet fuel"

We could subdivide "oil" by origin:

• fossil/"mineral"
• organic/"recent"
• synthetic

But would this be useful?

We could add a new class for "petroleum product", defined as any material derived from petroleum (crude oil), and define different oil distillation products here... but feels like overmodelling for ENVO purposes.

We use the chebi class 'fossil fuel' for has-role assignments:

/ CHEBI:50906 ! role [DEF: "A role is particular behaviour which a material entity may exhibit."]
  is_a CHEBI:33232 ! application [DEF: "Intended use of the molecular entity or part thereof by humans."]
   is_a CHEBI:33292 ! fuel [DEF: "An energy-rich substance that can be transformed with release of usable energy."]
    is_a CHEBI:35230 ! fossil fuel ***  [DEF: "A fuel such as coal, oil and natural gas which has formed over many years through the decomposition of deposited vegetation which was under extreme pressure

IMHO, the job of the CHEBI role branch is to define roles. 'fossil fuel' sits uneasily in role. I think fossil fuel should be defined as a material entity that has fuel role and has the necessary derivation conditions.

We are probably not the right people to do this classification, and ISO standards and so on exist in this area. But I feel we could go some way to improving this.
