Qa³ has extensive experience in the determination of mercury in samples originating upstream through midstream to downstream processing and in the final refined products.
For the upstream oil and gas sector during exploration and appraisal well testing worldwide, Qa³ provide experienced chemists to quantify mercury in:
- Stabilised and pressurised oil and condensate
- Produced gas
- Produced water
- Process chemicals e.g. amine, glycol
- Solids e.g. scales, sludges, deposits, filtered particulates and molecular sieve
- Drilling muds and brines
For the downstream oil and gas sector onshore and offshore worldwide.
Qa³ provide experienced chemists to quantify mercury in all process samples and chemicals. A common requirement of downstream clients is to obtain a better understanding of mercury distribution across their process. Qa³ are able to provide a mercury mass balance survey across a facility to give process operators a clear picture of mercury partitioning within the process. It is important for clients to understand where in the process mercury may be accumulating or being removed.
If installed Qa³ can monitor mercury across a removal bed to check bed efficiency and potentially bed life.
If mercury is present in a process it can often be critical to conduct mercury monitoring during plant shutdowns to ensure workers are not exposed to mercury vapour in the air released from process equipment after breaking of containment. Qa³ have carried out monitoring of workplace air for clients ensuring compliance with occupational exposure limits for mercury as well as provided training to client’s to allow them to bring this service in house.
Sometimes it is necessary to understand the form of mercury in order to evaluate likely partition routes and also to decide what technology to select for removal of mercury. Qa³ can conduct a detailed functional speciation suite on site on the clients installation. Performing this work on site is vital to minimise the chances of mercury losses to sampling vessels or species reaction or changing form.
