2017 – Current Projects
Performing an extensive sampling and analysis campaign for a number of analytes onshore and offshore in the Republic of the Congo.
Investigation into the efficiency of a recently installed mercury removal bed onshore Thailand.
Quarterly and annual mercury surveys at several onshore facilities in the UK.
In depth mercury speciation investigation in hydrocarbon condensates at a processing facility in Russia.
Construction and implementation of a bespoke laboratory quality system in accordance with ISO 17025
2016 – UK ON SITE SURVEY
Qa3 chemists conducted bespoke functional speciation analysis on naphtha samples for a leading mercury adsorbents manufacturer. In addition to the standard speciation analysis performed by Qa3, the mercury was further speciated according to boiling point, utilising a heat ramp and trap technique to drive off low boiling species of mercury. This work also included investigation into the most effective extraction techniques to remove soluble ionic species.
2016 – USA ON SITE SURVEY
Qa3 performed a sampling and analysis survey at a gas processing facility for subsequent arsine (AsH3) and phosphine (PH3) determinations by ICP-OES. The work involved deployment of Qa3 bespoke sampling traps specifically designed to capture these species from gas streams. Qa3 also trained the clients staff in both sampling for and analysis of the gas.
2016 – Thailand ON SITE SURVEY
Qa3 chemists conducted a speciation study of hydrocarbon condensate sampled pre and post a mercury removal unit on behalf of an absorbent supplier to better understand the forms of mercury present and thus allow the client to offer the most suitable adsorbents for the successful removal of mercury.
2016 – Norway ON SITE SURVEY
Qa3 performed an on site analysis and training campaign for the determination of radon-222 in gas. The chemists performed on site determination for radon-222 via two distinct methods and provided training on both techniques so the client could continue monitoring into the future.
2015 – Norway ON SITE SURVEY
Qa3 performed a sampling survey at a gas receiving facility for subsequent arsine (AsH3) and phosphine (PH3) determinations by ICP-OES back at the Qa3 laboratory. The client required determination of these analytes down to < 1 ppb as they are known to effect their on site catalysts. The work involved deployment of Qa3 bespoke sampling traps specifically designed to capture these species from gas streams.
2015 – UK ON SITE SURVEY
Qa3 chemists conducted complete mass balance mercury survey across a UK receiving facility. This included extensive sampling and analysis on site of pressurised NGL, process liquids and gases. This survey (and a number of others) are performed annually as a third party check for clients.
Qa3 was invited to investigate the efficiency of mercury removal units after an incident of liquid carryover into the units caused concern regarding their operation. The work conducted by Qa3 proved the beds to be working efficiently and confirming processed gas was on specification with regard to cryogenic unit feed, preventing the possibility of a plant shutdown. In addition to mercury, H2S, RSH, CO2 and O2 was determined in various gas streams.
2015 – Thailand ON SITE SURVEY
Qa3 chemists conducted two surveys on an offshore platform evaluating the efficiency of newly installed MRU’s. The work carried out by Qa3 highlighted a liquids carryover issue and identified remedial action required to the process in order for the MRU’s to operate successfully.
2015 – North Sea ON SITE SURVEY
Qa3 was requested to determine the concentration of oxygen in gas from a North Sea producer to ensure it was below the CATS entrance specification of < 9 ppmv. The Qa3 at line analyser can determine oxygen in gas down to 1 ppmv.
2015 – Thailand ON SITE SURVEY
Qa3 were requested to conduct a mercury mass balance survey across a client’s production platform in the Gulf of Thailand. The concentrations of mercury were found to be extremely high but, due to the low GOR, Qa3 confirmed the overall mass of mercury being produced was relatively low.
2014 – Tunisia ON SITE SURVEY
Qa3 was requested to perfrom a sulphur survey over a gas processing facility after copper suggested the presence of an unknown sulphur species. This involved extensive on site analysis and sampling for off site analysis for COS back in the UK. Oxygen was determined on site using the Qa3 at line analyser to see if could potentially be the source of the corrosion.
2014 – Angola ON SITE SURVEY
Qa3 was requested to provide expertise to carry out mercury determinations in produced gas on board an FPSO as part of a specification monitoring programme.
2014 – Algeria ON SITE SURVEY
Qa3 was requested to conduct a mercury survey at a gas plant after previous work by another laboratory suggested mercury removal beds were not performing satisfactorily allowing the majority of mercury to pass. The work conducted by Qa3 proved the beds to be working efficiently and confirming processed gas was on spec preventing the possibility of a plant shutdown.
2014 – Azerbaijan ON SITE SURVEY
An international oil company wanted to understand the concentration of mercury in gas being produced from a reservoir in the Caspian Sea. This project involved not only measurements across the onshore processing facility but also an offshore investigation to identify which wells (and hence which zones within the reservoir) were contributing the most mercury.
2013 – Oman ON SITE SURVEY
A Qa3 chemists conducted an on-site detailed mercury survey during an extended well test programme. Mercury was determined in the produced gas, condensate and water and the types and forms (species) were also identified to better understand the mercury chemistry in future process design.
Qa3 project managed a detailed mercury survey across a large LNG/LPG gas processing facility in Norway. The survey focused on mercury distribution and separation within the process system and also to evaluate the mercury treater bed performance. Analysis involved more than 30 separate sampling points across the processing plant, including monitoring of mercury in regeneration gas across the drying cycle of molecular sieve units.
2012 – UK ON SITE SURVEY
Mercury determinations on produced gas and oil were carried out by Qa3 chemists during well testing as part of the on-site chemistry on an exploration rig in the North Sea.
2011 – Belgium ON SITE SURVEY
A refinery in Belgium had a requirement to determine trace contaminants in there process gas for a new process that was being installed at the refinery. This was a very challenging piece of analytical chemistry and the client had said that they could not find any laboratories in Europe to conduct the work. Two chemists currently employed by Qa3 had the capability and experience for the scope of work involved. The work involved determination of mercury (as well as approximately 30 other contaminants) in a variety of gas process streams some of which contained % concentrations of hydrogen sulphide. The client was very pleased with the data produced and has since invited our chemists back to the plant to conduct further analysis at different points in the process.
2011 – UK ON SITE SURVEY
A mercury survey was carried out across the processing facility on board a platform in the North Sea by one of our experienced chemists. The survey established mercury concentrations in the inlet gas and at various points across the process including dryers and export.
2011 – Ghana ON SITE SURVEY
A chemist from Qa3 carried out mercury determinations on produced gas and oil during a well test as part of well test on-site chemistry on an exploration rig off the coast of Ghana
