FSI Standard Degassing Procedures

ICE technology uses "Internal Combustion's Engines" to abate the hydrocarbons with no flare.

Technology that meets the EPA demands with proper electronic reporting licensed with ICE technology to abate unwanted hydrocarbons in tanks, lines, barges etc.

1. FSI operators arrive with degassing unit to the job-site with 2 operators in most situations.
2. Review the following with the Client, Project Coordinator and General   Contractor with all FSI and non-FSI operators present on the job-site:

3. Sample the tank vapor space for hydrocarbon content. Make an estimate for the degassing time and report the time estimate to the project coordinator.
4. If there exists no access to the tank vapor space, make a request to the project coordinator that FSI's man-way be installed on the tank by Client’s personnel or by the contractor.
5. Identification and control of ignition sources including bonding and grounding
6. Connect the 3” hose to the tank via the existing access or via FSI's man-way.
7. Making sure that the path to the storage tank is still closed, start the degassing engines on propane from the unit’s propane tank.
8. After the engines have warmed up for minimum of 10 minutes, we start extracting tank vapor into the engines.
9. Monitor the tank vapor space, extracted vapor at inlet to the Degassing unit, and engine exhaust for hydrocarbon concentrations. Record these values and the vapor extraction rates on the log sheet every 20 to 30 minutes.
10. Leave the TLV unit running immediately upwind of the Degassing unit with the alarm set at 5% of LEL. Should the audible alarm ring at any time during the degassing operation, shut the degassing unit immediately.
11. After an estimated two hours of degassing, revise the time estimate and report information to the project coordinator.
12. Continue degassing until one of the following conditions have been met meaning Local APCD's requirements:

A. Meet California Rule 1149- tank vapors need to be 5,000 ppm or less measured as Methane and hold for (1) hour.
B. Meet Texas MSS permit condition- tank vapors need to be 34,000 ppm or less measured as Methane and FSI chooses hold for (1) hour.

13. If the client requires further degassing (e.g., 10% LEL), continue degassing until the client’s requirement is satisfied.
14. Report to the project coordinator that the TNRCC requirement has been     satisfied. When approved   for termination, switch engines back to propane and close the extraction valve. Disconnect the extraction hose from the storage tank man-way. 
15. Flush the extraction hose completely with air for a minimum of 5 minutes  before engine shut down is activated.
16. FSI Operator will complete all the following before leaving the job-site:
     
      A. Test air horn or a coppus blower for operation.
      B. The project coordinator has authorized FSI's departure. from the job-site,
           and project coordinator has signed off on all log sheets.
