 PLANNING WASTE OIL UTILIZATION
CHAPTER 2.
2.1 SCOPE. This chapter discusses factors to be considered and evaluated for
using waste oils as burner fuel; waste oil generating sources, oil products
found in waste oils, oil products which should not be burned, waste oil
restrictions, and boiler fuels presently used. Air emission considerat ions,
combustion considerat ions, and economic considerat ions are also discussed.
2.2 SOURCES OF WASTE OIL. The basic sources of waste oil generated at Navy
activities are ships in port, aircraft fueling and maintenance activities,
and other industrial/shop functions performed ashore. Collect ion and
disposal can be conducted independently in various organizations or as
functional elements, of an activity. Centralized collection and use of the
waste oil as a fuel may be profitable for the activity.
Although over 80 percent of the volume of waste oil generated throughout
the Navy is obtained from ship bilge and ballast water brought ashore,
activities having no port facilities may also generate enough waste oil to
make its use as a supplemental fuel a worthwhile energy conservation measure.
2.2.1 Ships in Port. The primary source of waste oil from ships is the
bilge/ballast water pumped ashore. Most activities handle this waste with
Waste Oil Rafts (DONUTS), which perform an initial gravity separation
function. The waste oil residual obtained is either further treated by oil
separation equipment, if available, or transferred to storage tanks for
disposal (usually by sale).
Ships may also generate waste oil products that are brought ashore in
drums and other containers. Types and quantities of this waste vary,
depending upon the type of ship. Industrial-type ships, such as tenders,
aircraft carriers, and large amphibious ships are the most likely generators
of significant quantities. Examples of these wastes are contaminated fuels,
turbine engine oils, hydraulic fluids, shop lubricants, carrier arresting
gear and catapult hydraulic fluids, greases, and solvents of all kinds.
2.2.2 Aircraft-Related Functions. At Naval Air Stations, a major source
of waste oil is aircraft fueling and maintenance. Contaminated fuels that
are unacceptable for reuse are a main source of waste oil. In aircraft
maintenance shops, fuel tanks are purged, oils drained, etc., thus generating
waste oils that must be disposed. To a minor degree, these functions may be
performed aboard aircraft carriers while in port and may generate some wastes
to be brought ashore.
