Q2 Technologies, a former subsidiary of Quaker Chemical which developed the MEA-Triazine scavengers used world-wide today, along with its Gulf Coast region distributor, Additive Direct Services have brought to market the Pro3® series of non-amine/non-triazine H₂S scavengers. The Pro3® series is the next generation of scavengers replacing MEA-Triazine in liquid hydrocarbon streams.

The Pro3® series is the result of a need to reduce fouling/corrosion created by amine based scavengers in refineries, production streams and crude oil terminals while improving H₂S removal performance compared to that of MEA-Triazine.

CHALLENGES
  • Two 100,000 barrel inland collection crude oil storage tanks were being injected with up to 500 GPD of 40% MEA-Triazine.
  • Approximately 150 trucks unloaded daily at the terminal with Hâ‚‚S levels ranging from 30 ppmv to 25,000 ppmv.
  • A high level of Hâ‚‚S in collection tanks was still observed after triazine injection and required the customer to have expensive independent Hâ‚‚S monitoring done followed up with additional treatment and delays.
SOLUTION
  • Pro3® was recommended to substitute 40% MEA-Triazine
    scavenger and to reduce chemical cost and logistics.
  • An injection system consisting of a single 6,000 gallon ISO tank with automated pumps replaced a system of 5 individual tote tanks being used to inject 40% MEA-Triazine.
RESULTS
  • Storage Tank Hâ‚‚S level using MEA-Triazine: > 10 ppmv
  • Storage Tank Hâ‚‚S level using Pro3®: <1 ppmv.
  • Approximately 3 million barrels of EFL/EFR/WTI
    are treated monthly with Pro3® series.
  • Chemical consumption was cut 80% compared to the 40% MEA-Triazine resulting in:
    – Deliveries cut by 75% translating into increased personnel productivity.
    – $35,000 per month reduction in chemical cost. *Will vary on application requirements
  • The need for Hâ‚‚S monitoring personnel was eliminated resulting
    in additional savings. Spot checks and daily electronic monitoring
    are now sufficient to maintain a safe environment.
  • On-site bulk storage of chemical resulted in logistics and freight costs.

TAKE-AWAYS:

  • >$35k per month chemical savings.
  • Deliveries cut 75%.
  • Chemical use cut by 80%.
