Definitions
- the invention relates to a method of creating an all-loss lubricant. Further, the invention relates to a system for creating an all-loss lubricant.
- Two-stroke crosshead engines used in marine or stationary applications are equipped with two separate lubricating oil systems.
- One lubricating system comprises so-called system oil that normally is used for lubrication and cooling of the engine's bearings and e.g. oil-cooled pistons as well as for activation and/or control of various valves or the like.
- the other lubricating system comprises an all-loss lubricant (cylinder oil) that normally is used for lubrication of the engine's cylinders, piston rings and piston skirt.
- cylinder oil all-loss lubricant
- the cylinder oil In typical two-stroke crosshead engines, the cylinder oil is spent continuously by each turn of the engine whereas the system oil in principle is not spent (except by smaller unintentional leakages).
- the lubrication system comprising the cylinder oil is also often referred to as an "all-loss" lubrication system as the oil is spent.
- all-loss lubrication system
- the use of and various types of both system oil(s) and cylinder oil(s) is very well known in the art.
- the cylinder oil typically contains certain additives that function to reduce, minimize or neutralise the acid level of the cylinder system.
- Typical cylinder oils usually have an SAE (Society of Automotive Engineering) viscosity equivalent to about 50 and normally have a total base number (TBN) of about 40 to 70 for the neutralisation of acid products produced during the combustion process.
- Typical system oils usually have an SAE viscosity of about 30 with a relatively low TBN content, typically below 10. These exemplary values may vary dependent on the actual application and the specific design of the systems that the oils are used in.
- trunk piston (diesel) engines typically use only a single oil type for lubrication and cooling. Such engines are used as secondary/auxiliary or propulsion engines on ships, or in stationary power generation or liquid/gas transmission applications. Such used oils typically have a SAE viscosity of about 30 or 40. While the system oil of two-stroke cross-head engines typically remains within its specified performance limits for an extended period of time, trunk piston engine oils are constantly affected by exposure to the combustion process. However, due to the inherent design of two-stroke cross-head engines, spent cylinder lubricants invariably leaks past the piston rod stuffing box contaminating the system oil.
- the performance level of lubricants is typically measured periodically and may not go beyond certain limits if the oiled component's condition should not be jeopardized.
- An important cause of performance loss is caused by particle contamination. These particles include combustion by-products and wear components, which can be partially removed by oil separators.
- one of the sources of contamination is spent cylinder oil leakage past the stuffing box causing both the viscosity and base number of the system oil to increase over time, a process that cannot be reversed by separators.
- a diesel engine's frictional loss is mainly of a viscose character.
- An increase in the viscosity of the system oil will therefore result in a diminished efficiency, increased fuel consumption and increased emissions.
- prior art methods and systems typically blend suited base oils and suited additives and/or an additive package to obtain a fully formulated cylinder lubricant. This is typically done at a dedicated lubricant blend plant and the resulting cylinder lubricant has to the delivered to a ship or an off-shore plant for use in engines.
- a further object is to provide this in a cost-effective and simplified way.
- a further object of the present invention is to enable improved performance of non-total loss lubricants over time and thus a more efficient use of both non- total loss lubricants and cylinder oil.
- a method of (and corresponding system) creating a cylinder oil comprising modification of at least one initial fluid by determining the TBN(s) of the at least one initial fluid, determining a desired TBN of a cylinder oil and adjusting the TBN(s) of the at least one initial fluid accordingly by blending the at least one initial fluid with suited additive(s).
- lubricants that otherwise would have to be disposed of can be re-used as a total-loss cylinder lubricant.
- cylinder oil does not have to be purchased.
- the oil(s) used to blend the cylinder oil is/are of more consistent quality as it is replenished (contrary to the traditional practice) which reduces machinery wear, etc.
- the replenishment of the initial fluid(s) provides enhanced and consistent performance of the initial fluids resulting in greatly reduced component wear and equipment lifecycle cost.
- a more environmentally friendly method/system is provided since waste, in the form of spent oil(s) that is discarded after prolonged use, is reduced as it is converted into cylinder oil.
- At least one of the initial fluids are at least partially used oil(s).
- a fully formulated cylinder lubricant is obtained by modifying TBN of this used initial fluid(s).
- the suited additive(s) comprise at least one base.
- the at least one base comprises 1. basic salts of alkaline or earth alkaline elements, and/or 2. detergents and/or 3. dispersants.
- the alkaline / earth alkaline elements may be e.g. K, Na, Ca, Ba, Mg or the like.
- the basic salts may belong to the inorganic chemical families of e.g. oxides, hydroxides, carbonates, sulfates or the like.
- the detergents may belong to the organic chemical families of e.g. sulfonates, salicylates, phenates, sulfophenates, Mannich-bases and the like.
- the dispersants may belong to the organic chemical families of succinimides or the like.
- the cylinder oil is used in reciprocating internal combustion engines used in marine or stationary applications.
- the reciprocating internal combustion engines are two-stroke crosshead engines.
- the method and embodiments thereof according to the present invention is used offshore, on-site or in a land based plant.
- the cylinder oil is created with a TBN in response to fuel oil characteristics and/or actual engine operating requirements.
- the TBN of the cylinder oil is chosen based upon sulphur-content of the fuel oil.
- the initial fluid is a hydrocarbon fluid.
- the hydrocarbon fluid is a lubricant.
- the lubricant is a used lubricant, i.e. a lubricant that has at least been partially used elsewhere.
- the used lubricant is selected from a group of lubricants, such as hydraulic fluids, gear oils, system oils, trunk piston engine oils, turbine oils, heavy duty diesel oils, compressor oils and the like.
- the created cylinder oil is based on two-stroke engine system oil that continuously, near-continuously or intermittently is tapped from an existing system and where the system oil is replenished.
- the created cylinder oil is based on a mixture of lubricants that continuously, near-continuously or intermittently are tapped from an existing system and where the lubricants are replenished.
- oils used as initial fluids may e.g. be used or could alternatively be non- used, i.e. straight from any fresh lubricant storage tank or the like.
- the method further comprises the step of using suited instrumentation in order to control the quality of the finished lubricant.
- the present invention also relates to a system corresponding to and having the same advantages as the method of the present invention. More specifically, the present invention also relates to a system for providing a cylinder oil, the system comprising: an apparatus for modifying at least one initial fluid by determining the TBN(s) of the at least one initial fluid, determining a desired TBN of a cylinder oil and adjusting the TBN(s) of the at least one initial fluid accordingly by blending the at least one initial fluid with suited additive(s).
- Advantageous embodiments of the system according to the present invention are defined in the sub-claims and described in detail in the following. The embodiments of the system correspond to the embodiments of the method and have the same advantages for the same reasons.

- reciprocating internal combustion engines e.g. two-stroke crosshead engines
- the creation of a cylinder oil is due to its simplicity and the normal availability of the required initial fluid and the additives very suitable for offshore or on-site applications.
- the creation of the cylinder oil may also take additional aspects into consideration such as actual engine requirements and sulphur content of the fuel.

- the process may also be used to provide flexible TBN levels as required by the actual fuel oil properties and engine operating parameters.
- cylinder oil/cylinder oil is due to its simplicity very well suited for on-site creation, e.g. aboard a ship / vessel, off-shore equipment, stationary plants, etc.
- any reference signs placed between parentheses shall not be constructed as limiting the claim.
- the word “comprising” does not exclude the presence of elements or steps other than those listed in a claim.
- the word “a” or “an” preceding an element does not exclude the presence of a plurality of such elements.
