Tekran - Model 2642 - Natural Gas Fixed Sampler
From Natural Gas
Tekran and VE Technology have partnered together to improve the quality of Natural Gas sampling and analysis. Proper sample collection requires precision equipment to assure mercury is quantitatively transported between the source pipeline and the sample collection device. The Tekran 2642 Natural Gas Sampler paired with a Tekran 2600-NG provides a complete sampling and analysis solution.

Products Details
Sampling mercury in a natural gas matrix presents many challenges. The trace amounts typically found in natural gas are typically adsorbed to the surfaces of the sampling equipment. This is due to the relative chemical potential of mercury and it’s affinity of surfaces and particles in the sample stream. The Tekran 2642 combats these issues by using electropolished and SilcoNert coated sampling components along with heating of the entire sampling train to assure quantitative transport of mercury.
The Natural Gas Sampler (Tekran Model 2642) is designed to be installed at a fixed point. All wetted surfaces are both electro-polished and SilcoNert® coated to ensure 100% Hg transport. The 2641 also incorporates a gas pre-treatment device to filter the sample stream and eliminate Joule-Thomson cold-spots during pressure reduction. Sample performance improves with the addition of a custom probe with helical strakes to minimize vortex shedding and aerodynamic probe tip to actively reject particulate from the sample stream. The system includes a double block and bleed valve for safe sampling of high pressure gases. The sampling components are housed in a NEMA enclosure.
