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 ProM® series of non-amine/non-triazine mercaptan scavengers. The ProM® series is the next generation of scavengers replacing MEA-Triazine in liquid hydrocarbon streams.

The ProM® 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 mercaptan removal performance compared to that of MEA-Triazine.

CHALLENGES
  • A 50,000 bpd condensate splitter was facing fouling issues from MEA-Triazine.
  • High volume of MEA-Triazine failed to reach crude oil mercaptan specification.
  • The terminal was required to blend down various types of crude oil from different storage tanks to achieve a mercaptan specification ranging from 2-5 ppm.
SOLUTION
  • ProM® was recommended to meet mercaptan specifications at the terminal, reduce amount of blending required and reduce fouling and corrosion problems at neighboring condensate splitters.
  • Extensive laboratory testing with different blends of EFL/EFR/ WTI indicated that the ProM® could meet required mercaptan specification of a variety of condensate blends.
  • A dual pump on-site injection system and chemical bulk storage with 24/7 support staff allowed for treatment of large volumes of crude oil on demand.
RESULTS
  • Pre-treatment Mercaptan level: 10 – 30 ppm per UOP-163/D-3227
  • Post-treatment Mercaptan level: <2 ppm
  • Condensate splitter feedstock of up to 1.5 million barrels per month was treated to reduce mercaptan levels and meet specification.

TAKE-AWAYS:

  • ProM® chemistry allowed customer to meet mercaptan specifications that MEA-Triazine was unable to reach.
