Outline of Transfer Procedure

The following is a description of the "steady-state" procedure. The start-up procedure follows in the next section. The shut-down procedure is still to be determined.

1. Oil arrives at Fermilab railhead in rail tanker car.
2. Small sample is extracted from bottom of car for testing:
   • Sample sent to lab for:
     1. Denisty
     2. Viscosity
     3. Sabolt color
     4. Flash Point
     5. Pour Point
     6. Visual examination for contaminants
   • Sample tested at Fermilab for:
     1. Density
     2. Index of Refraction
     3. Attenuation Length
3. Oil is transfered to detector at rate of two truck loads/day. Expectation is that we will need two trailers for this process: one at railhead filling, and one at detector emptying. Expect that the delivery to the detector will be the bottleneck. We want to flow into the detector at a rate of one tanker per eight hours (may go to 4 hours when we are comfortable with procedure or when oil is higher in the tank). Expect to fill during two shifts with tankers shuttled back and forth first thing in the morning and last thing in the afternoon.
4. Personnel:
   • Techicians fill tanker at railhead and help unload at detector.
   • Physicist from experiment in charge of unloading at detector.
   • Driver shuttle trailers in early morning and late afternoon.

In normal operations, we expect to pump directly from the tanker trailer into the tank.

Start-Up

At start-up we anticipate that the transfer will be done very slowly (we may take up to a week to transfer the first truck trailer). Each trailer will be filled, a small sample extracted from the bottom of the trailer and tested at Fermilab for attenuation length and visual contaminants. The first tanker will be pumped into the overflow tank (and bubbled with nitrogen?). The oil will then be pumped from that tank into the detector.

Initially, a small amount of oil will be pumped into the tank with the lower manhole open. We will then extract a small amount of oil and test it for attenuation length and visual contaminants. We then will close the manhole and continue filling.

Shut-Down

The tank is full when it begins to flow out of the overflow pipe and fills the overflow tank to half full. We must wait for the tank temperature to come equilibriate and then either top off or bleed off oil in the overflow tank to get to the half filled level.

After the tank is full, we anticipate that we will have approximately 2500 gallons of oil left over. We must decide how much of this we wish to keep and where, and how much we wish to dispose of and how.
