Revision Date 8/28/2018
3.1.1.7. Verify that all flexible lines are attached to top and bottom of vessel.
3.1.1.8. Open the Vessel Isolation valves once vessel is secure.
3.1.2. Prepping and Securing Separators
3.1.2.1. Before running a separator, be sure that the separator is clean and the proper orifice for
the desired operating parameters is selected. See recommended operating parameters
section for orifice sizing information.
3.1.2.2. Separators are secured with sanitary clamps. Clamps are considered tight when both
nuts are torqued to 20 ft-lbs. Use the supplied torque wrench to accomplish this tightness
3.1.2.3. Verify that all tubing connecting the separator vessels to each other of the rest of the
system is connected and tight.
3.1.2.4. Close Valve 10 and the Evacuation Valve
3.1.2.5. Open the Vessel Isolation Valves once vessel is secure.
3.1.3. Evacuating System
3.1.3.1. From the manual screen press “Evacuate”
3.1.3.2. Open the evacuation valve on the separator bank that will be online first and attach the
vacuum pump to the bottom of the evacuation valve with the supplied hose and gauge.
3.1.3.3. Verify that the vacuum pump has the appropriate level of clean oil and then start the
vacuum pump.
3.1.3.4. Let they system come down to between -25 to -30 inHg and maintain for several minutes.
If system does not come down there is a leak into the system or the vacuum pump needs
service (close the evacuation valve and watch the gauge to see which it is).
3.1.3.5. Close evacuation valve, turn off vacuum pump, remove hose and gauge.
3.1.3.6. Acknowledge that evacuation is complete on the manual screen.
3.2. Starting the Cycle
3.2.1. The Cycle Parameters Screen – To get to the Cycle Parameter Screen first go to the Main
Screen from the bottom navigation button and click on Cycle Parameters above the extractor
icons. Once on the cycle parameter screen follow the prompts on the screen which are also
listed below
3.2.1.1. Verify that all vessels to be ran are secure.
3.2.1.2. Close valve 10 and the Evacuation valve on separator bank(s) to be ran.
3.2.1.3. Open the two vessel isolation valves on the separator bank(s) to be ran.
3.2.1.4. Open all bottles.
3.2.1.5. Verify that system has adequate air pressure (between 90-115psi).
3.2.1.6. Select which mode to run the system in (Continuous, Single or Double).
3.2.1.7. Select extractor to be online at the start of the run/flow direction of the run.
3.2.1.8. If Continuous Batch is selected, a popup window will show at this time asking the
operator to enter an extractor vessel time interval. This is the total time each extractor will
run before coming offline. (e.g. If the extractor interval is 6 hours and vessel A is brought
online first the system will run vessel A by itself for 4 hours and then bring vessel B online
with Vessel A for 2 hours be for switching over to vessel B solely for 2 hours, NOTE: the
first vessel will run for double the amount of time of each additional interval)
3.2.1.9. Enter Phase 1 extractor target pressure and temperature.
3.2.1.10. Enter Phase 1 desired separator temperature.
3.2.1.11. Enter total run time.
3.2.1.12. Select separator bank to be online first.
3.2.1.13. Enter Phase 2 extractor target pressure and temperature.
3.2.1.14. Enter Phase 2 desired separator temperature.
