Abstract
Hazardous waste substances are diluted with raw sea water to a safe level. The resultant solution is transported by sea tanker to a disused sub-sea oil well production platform and pumped into tanks aboard the platform and further diluted. The further diluted solution is then pumped into the well bore, using the existing platform equipment, and on into the oil reservoir for permanent disposal.
Description
ATTENUATED HAZARDOUS WASTE DISPOSAL SYSTEM
This invention relates to the attenuation [reduction] of toxicity levels of hazardous waste substances and their disposal within sub-sea disused oil wells.
Disposal of hazardous waste substances by current methods of landfill or incineration and other methods, which are land based, cause short and long term problems and dangers to man and his environment, which are becoming socially intolerable and are attracting legi slat iv e measures against them. Land based hazardous waste disposal tends towards the impossible as a long term solution.
According to the present invention there is provision for reducing the measured level of toxicity bv volume of various waste substances by dilution with raw sea water, especially those scheduled by the European Economic Community. initial dilution takes place prior to transportation by sea tanker to a disused oil production platform and oil well. Subsequently, the further reduction of volume toxicity by dilution with raw sea water aboard the oil platform renders the waste to a very low level of toxicity and suitable viscosity for pumping into the well bore and reservoir for permanent disposal. Should any future escape of the disposed waste occur the toxicity level will be too dilute to cause pollution damage to marine or human life and environment.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which :- Figure 1. shows the plan view of a module of the layout and components of the on-shore dockside terminal, tank farm, pumping systems and attenuation tank.
Figure 2. shows in elevation the rock stratum and related sub-sea oil reservoir with its well bore access from a surface located oil production platform with pump house, storage and attenuation tanks. Figure 2 also shows a sea tanker off loading "QUARTRATED" hazardous waste substances via a flexible pipeline, into tanks on the platform for dilution and disposal in the oil reservoir.
Referring to the drawings Figure 1 shows the on-shore waste reception terminals, T1 to T4, and the storage tanks C1 to C4, with feeder pipelines leading from each to a junction J1. The outlet pipeline from the junction leads to a positive displacement pump, P1, which propels the waste to the attenuation tank AT1, where an impellor, I1, causes dilution to take place using raw sea water pumped into the tank, AT1, from sea-water terminal, SWT, by pump, SWP. This is the "QUARTRATION" stage of the process.
The diluted [QUARTRATED] waste substances are then pumped [P2] to a terminal, ACLT, on the dockside and then aboard a sea tanker, CT, for transportation to an oil production platform, ORP, as shown in Figure 2.
Referring now to Figure 2.:
The diluted waste substances are pumped from the sea tanker CT, through valve A and via a flexible pipe,
FP, to various attenuation mixing tanks, AT1 and AT2, aboard the oil platform, ORP, for stage two dilution C"CRITICAL ATTENUATION LEVEL" with raw sea-water reducing the toxicity to a very low level and having a suitable viscosity for pumping into the oil reservoir.
The further diluted substances are then pumped, via the oil platform's existing pumphouse facilities, ORPH, into the well casing, CS, through the wellhead, WH, and on through the wellbore [WB] into the disused oil reservoir [OR].
Upon reaching the capacity of the oil reservoir and wellbore to the full, the wellbore is sealed with a concrete plug, WBCS, 5û metres deep and the wellhead sealed off in accordance with international legislation.
This procedure is followed for disposal of attenuated waste substances into further suitable disused oil wells as they become available.
Claims (1)
- A process of treating hazardous waste substances byproportional dilution with raw sea-water [QUARTRATION] to reduce volume toxicity before transportation by sea tanker.A further process to that in CLAIM1 of diluting the "QUARTRATED" solution of waste substances in raw sea water to a minimally hazardous level, the "CRITICAL ATTENUATION LEVEL".Disposal of the solution of hazardous waste products produced by the processes as claimed in CLAIM 1 and CLAIM 2 into the empty reservoir of a disused sub-sea oil well using the equipment normally found aboard an oil production platform with the addition of mixing tanks and storage facilities and any other necessary handling equipment. The well is sealed with a 50 metre concrete plug and the wellhead closed out upon disposal capacity of the well being reached.A volume toxicity reduction process in two stages leading to disposal within disused sub-sea oil well reservoirs as described herein and with reference to Figures 1 and 2 of the accompanying drawings.
