  • ABSTRACT [30] Foreign Application Priority Data July 3, 1972 Japan 47-66541 An oil delivery System wherein, in Order to effect the discharge of solidified or semi-solidified oil remaining 52 11.5. C1 137/13, 137/15, 137/571, in a tank eftet P t delivety ef the bulk of the 137/334 7 5 134/5, 134/24, 7 3 therefrom, a nozzle is inserted in the free space within [51 1111.
  • the present invention relates to an oil deliverry sys tem for oils having a high melting, and more particu larly to an oil delivery system for the discharge of solidified or semi-solidified oil, which is ofspccial advantage in secondary. or final evacuation of high melting point oils. or similar substances, held in a solidified, or semisolidified state in a tank.
  • a nozzle, or nozzles are inserted into a tank, or similar container holding residual, solidified or semi-solidified oil which it is desired to discharge, and oil that has been previously discharged from the tank, or the same type of oil from another source, is projected through the nozzle, or nozzles onto the residual oil. whereby the residual oil is melted and made easily removable from the tank.
  • Bulk transport of oil is normally effected by ships that are equipped with suitable tanks, and oil is generally delivered therefrom by being pumped out.
  • oil in a tank is solidified or semi-solidified, as is often the case with beef tallow. coconut oil, or highly viscous mineral oils.
  • this method of delivering solidified or semi-solidified oil is only effective for mammoth tankers, or similar large vessels with double bottoms, and is not feasible for coastal vessels used for oil transport, which are mostly single-bottomed. When oil is piped from these smaller vessels, at considerable amount of oil.
  • Another disadvantage and undesirable feature of this conventional method is that it is extremely difficult to effect removal of the entiretry of the residu'al oil, and even after manual cleaning of the tank. there is still some oil left, which is discharged into the sea after final washing ofthe tank, thus contributing to environmental pollution.
  • This problem is not of course limited to sea-transport of oil, but is also present with regards to inland transport and storage of oil. g
  • lt is a further object of the invention to provide an oil delivery system that, unlike conventional systems, does not demand recourse to manual labour for the removal of residual oil in a tank.
  • Another object of the invention is to eliminate a factor of environmental pollution that is conventionally inherent in oiling stations.
  • a still further object of the invention istQ provide an oil delivery system wherein only the oil it is desired to dischage and obtain for later use is evacuated from a tank and wherein the employment of sea water. washing water, treated oil, or similar substances is not required, thereby rendering unnecessary both the expenditure of excessive energy and the separation of theoil it is desired to discharge from sea water, washingiwater; or treated oil.
  • Yet another object of the invention is to present an oil delivery system that offers particular advantages relating to sea-board industries havinga centralized coritrol system of mass-production.
  • a still further object of the invention is to provide an oil delivery system of simplified design.
  • an oil delivery system wherein, in order to effect the dischargeof solidified or semi-solidified oil remaining in a tank after primary delivery ofthe bulk of the oil therefrom, a nozzle, or nozzles are insertedin the free space within the tank, a certain portion of the oil previously discharged in the primary delivery, or oil of the same kind, but from another source, is heated and directed through the nozzle or nozzles onto the residual oil, which is thereby melted, and rendered easily removable.
  • the system of the present invention offers advantages in that the residual heat of previously discharged oilmay be used to effect the removal of residual oil in a tank, that there is no waste of oil, since a tank may be perfectly emptied, and that no extra labour force is required.
  • Types of oil for the delivery of which the system of the present invention finds application, are such oils as become solidified or semi-solidified. go into a jelly-like condition, or exhibit highly viscous flow characteristies, at ambient temperatures around an oil tank, that is, ambient air temperature, or water temperature. whichever is lower.
  • Example of such oils, or oily substances are the animal or vegetable fats or oils such as beef tallow (melting point 35-5()C), pork lard (melting point 2848C) palm oil (melting point 27-5()C), palm kcrnal oil (melting point 25-30C), coconut oil (melting point 2(l28C), or hardened oils or fractionated oils whose melting point temperatures lie in a similar range.
  • nozzles As examples of nozzles that may be employed, there can be cited'nozzles as used in known oil tank cleaning-means such as the Butterworth'Tank Cleaning Machine Toko Mini- Jet Washer, Victor Pyrate Automatic Tank Washer, Maersk-Clean, Toftejorg Tank Cleaning Machine, or
  • a cleaning means such as cited above and having either fixed or portable nozzle portions is provided in a tank, in the vicinity of the tank, or on a jetty. or other'unloading point. It is particularly advantageous. but not essential, to mount the cleaning means on a jetty, and to provide portable nozzles, so that any number of vessels may be dcalt with from the same point. Also.
  • nozzle portions provided are rotatable eccentric nozzle type com prising two or more nozzles inclined in different directions, there is not ced to provide a special support rod, or"simil ar means, for positioning the nozzles in a tank, but the'nozzles may simply b e suspended freely inside the tank. and h'catedoil projected therefromcvenly melts the residual oil.
  • the most suitable number of nozzles for. melting residual oil in a tank depends, of course. on the size of the tank. Also. it is evident that the use of rotatable. eccentric nozzles is not essential to thc system of the present invention, for it islcqually possible to c1nploy,for example, fixed nozzles directed vertically downwards.
  • nozzles for the ejection of heated oil are provided on a normal 'tankfir, or similar vessel. from which oil is to be delivered.
  • a storage. tank. pumps, a heaterLor heaters. strainers. and other conventional items of equipment are provided at the oiling station to which the oil s and storagetank son lahd may he equippcdas required with filters. straihfers'fet" for theelimination of undesirable matter from the pipe'doil.
