Measurement and Testing New Guide for Monitoring Industrial Emissions
In light of legislative changes governing how organisations should monitor their industrial emissions , FLIR Systems (France) has written a new informative guide: `Top Tips : How to get the most from Optical Gas Imaging (OGI)’.
One of the most significant advances in infrared thermographic cameras over recent years has been the introduction of Optical Gas Imaging. OGI cameras use spectral wavelength filtering and sterling cooler cold filtering technology to visualise the Infrared absorption of VOC/Hydrocarbon ; SF6 ; Refrigerant, Carbon Monoxide and other gases whose spectral absorption matches the response of the camera. By using OGI technology - industry is now able to incorporate a ‘Smart LDAR’ program that safely and efficiently visualise gas leaks.
OGI has allowed industry to reduce emissions thereby enabling operator owners to conform to strengthening environmental emission regulations, save money as part of a much more efficient process, but most importantly improve the safety of their assets and their workers.
The new FLIR ‘Top Tips’ guide offers advice on understanding your application needs ; Taking account of environmental conditions ; Learning what OGI can do for you ; How to use OGI as part of a LDAR process ; Improving safety ; Complying with incoming legislation ; How to work with Permits and Justification for OGI based on return on investment.

Optimised pH System for Coagulation/Flocculation Stages
The most critical pH measurements and control are for the ‘Treated Raw Waters’. The pH of these waters is critical in order to optimise the addition of flocculent/coagulation chemicals.
These raw waters especially in winter months are cold (close to freezing) and often low ionic. With these 2 factors, using pH sensors with porous reference junctions, it’s impossible to achieve stable and accurate pH measurement. Porous electrodes all suffer diffusion potential errors (ca pH 0.3) and at low temperatures the impedance of the pH glass membrane increases by a full decade (RT 20 C impedance of 200 MOhm at zero this becomes 2000 MOhm). The net result is hit and miss pH correction and addition of coagulant/flocculent chemicals. This lack of pH control affects the effectiveness of the coagulation that adversely affects the filtration stages downstream.
The Refex (Ireland) pH sensor uses a unique and patented hard-non-porous ionically conductive material that has replaced the need for the unreliable and inaccurate porous reference junction. The polymeric Refex material acts as an immobilised KCl electrolyte and also as an interface/barrier that separates the raw waters from the electrode’s internal Ag/AgCl half cell – hence there is no liquid contact/exchange. With no diffusion potential errors and Rock-Solid mV stability (no drifting) this Refex arrangement is almost maintenance free (every 90 days is achievable).
Accurate pH calibrations using buffers with values close to the pH value of the waters being tested – it’s possible to achieve a pH resolution of pH 0.01. Only the Refex electrode can achieve such tight resolutions.
Savings: Chemical Savings - Correcting / flocculation/coagulation > GBP 2000,--/month/WTW; Maintenance: Usually weekly or Bi-weekly calibrations can be extended to every 90 Days; Long Life – the Refex electrode lasts longer than all others (5-10 times longer life).
The Refex electrode has a higher impedance reference (< 1 MOhm), for this reason it is necessary to use a top quality pH transmitter that has duel high impedance inputs for both pH and reference electrodes. 2 x 10 x 12 Ohm is the best. This is very important.

Knowledge of the mercury content in oil, gas and petrochemicals is extremely important. Not only is mercury highly toxic and of great environmental concern, but also damage it can cause to plant equipment can lead to costly unscheduled shutdowns.
Even at low concentrations mercury may condense and accumulate in cryogenic aluminium heat exchangers due to the low temperatures and high pressures encountered. Under certain conditions of operation, liquid mercury may cause corrosion or liquid metal embrittlement resulting in a failure of the cold box.
Heat exchanger replacement is a costly operation and more importantly enforced shutdowns incur large revenue losses. Mercury is also known to cause de-activation of hydrogenation catalysts used in the petrochemical industry. Mercury removal technologies must be employed and their efficiency monitored.
P S Analytical (UK) offers a wide range of services and Hg monitoring equipment for the oil, gas and petrochemical industry. Online and laboratory systems are routinely tailored to meet the specified monitoring levels, legislatory and site- specific requirements of each customer.
