The analyst stood there glaring at the CEMS (continuous emissions monitoring system). For the 2nd day in a row the system refused to produce consistent results. H2S results were low, then high, then...
Sometimes your nose knows better. When you were in the field you were sure you smelled the gas odorant, but now when the sample hits the GC SCD detector, nothing... Did I really smell the mercaptan?...
Monitoring process conditions and emissions are critical to plant performance. Unfortunately process sampling can be a complex and frustrating endeavor. Often analysts are frustrated by seemingly...
Recent revelations about diesel emissions highlight SilcoTek's contribution to improving exhaust emission testing. How do regulatory agencies detect low level NOx and sulfur emissions? Advances in...
A recent article in Hydrocarbon Processing, "10 Sure Ways To Substandard Reliability Performance" by H. P. Block discussed attitudes and factors contributing to poor plant reliability. The article...
H2S scavenging in oil and gas downhole sampling tools can have a significant impact on the ability of producers to accurately assess the safety, quality and value of a well. Vladislav Achourov,...
SilcoTek® R&D gave Dursan® a makeover. A tweak here, a process tuck there and now Dursan is the belle of the ball! Well as far as an inert coating can be a belle and I'm not sure there's a ball for...
Over the years, many inert coating solutions have been developed to enhance sampling system compatibility with reactive compounds like H2S and mercury (Hg), such as polytetrafluoroethylene (PTFE),...
A Texas refinery suspected higher than normal H2S in their flare gas. Yet the H2S sampling system showed emissions were within spec. But why was the low level calibration showing no H2S? The...
