The tar oil/water mix is offloaded from the Cajunizer onto the workboat for further processing. The workboat serves three functions:
1. On‐water command ship handling the overall operations
2. Initial processing facility that removes water and debris from the tar oils
3. Initial holding vessel for the tar oils after first processing
While effective retrieval in open waters can be obtained using the Oil Cajunizer and Tar Oil
Shrimping Fleet, the amount of liquid being transported needs to be primarily the tar oils, not waters picked up during retrieval. After first processing, the tar oils are transferred from the workboat to work barges for additional processing and shipping.
The Command Processing Workboat will be used for both command operations of the Shrimping fleet, but also for on‐deck first processing of the tar oils retrieved. In this way, free water and gray water from the emulsified tar oils can be cleaned and deposited back into the ocean. The Cajunizer starts the transfer to the work boat while additional pumping on board, handles the transference of liquids.
The on‐deck processing consists of the following main steps:
1. Initial Processing
2. Emulsified Oils Processing
3. Gray Water Processing
4. Dirty Water Electrolysis
In this fashion, the tar oils are converted to flowable oil that is stored in the holding tanks, improved and then transferred to the oil processing barge for additional processing and transport.
Screening to remove trash and debris: This material is transferred to a “trash barge” which moves the material to the on‐land Pyrolysis facility.
Separator/mixer/heater: This unit adds solvents to improve flow characteristics and API separation for oil droplet sizes down to 150 um. The utilization of the diesel engine exhaust heat improves the overall removal of the “oils” during this operation.
Transference: The oil removed during separator operations is stored in the holding tanks of the Command Processing Workboat until transfer to the oil processing barge occurs.
Holding Tanks: The emulsified oils and gray water are transferred to holding tanks for additional processing.
Emulsified Oil Processing
Technology: There are a variety of technologies available for this operation: CPI Hydrocyclone, DAF/IGF, centrifuge, etc. Utilization of viable equipment from the local area will help with the local economies.
Removal: The oil removed at this step is added to the oil removed during initial processing for later transference to the oil processing barge.
Gray Water: Gray water is transferred to the gray water holding tank.
Gray Water Processing
Kill Spill: The gray water is combined with Kill Spill oil absorbent with agitation for the quick removal of oils left in the gray water.
Removal: The used Kill Spill (10x oil absorption to dry volume) is stored and then transferred to the Pyrolysis facility for the production of diesel, kerosene, jet fuel and carbon black.
Clean Water. The cleaned water is then either discharged, or transferred to Dirty-water electrolysis units.
Dirty Water Electrolysis
Viscosity: The tar oils being collected in open waters are of low grade with significant debris in the material. Hydrogenation and possibly oxygenation of the “oils” will be necessary to upgrade to refinery grade for delivery to the existing pipeline system.
Removal: On board dirty water electrolysis of the cleaned gray water will help to reduce the Corexit signal while providing the inexpensive hydrogenation (and oxygenation) necessary for upgrade of the material.
Recovery: The bleach produced during operation will be transferred to shore for cleaning and for industrial and agricultural sales.
