Introduction
Natural gas samples often contain varying amounts and types of sulfur compounds, which can interfere with reaction or poison catalysts in many petrochemical processes. Because sulfur compounds quickly react with stainless steel surfaces, accurate determination of these compounds is impossible when using untreated sample cylinders. Sulfinert®passivation technique bonds an inert silica layer into the surface of the stainless steel. This layer acts as a barrier, preventing active compounds from reacting
with or adsorbing to the stainless steel. Sulfur and mercury compounds exhibit greatly increased stability to Sulfinert®-treated cylinder, which can be applied to the following fields: analytical process, environment detection, downhole sampling from petroleum and natural gas wells, as well as monitoring and control of oil refining and petroleum processes.
Sulfinert -treated Sample Cylinders
◎ Sulfinert coating to provide stable storage of sulfur and mercury compounds at ppb levels in petroleum samples for a long time
◎ Sulfinert coating not flaking off and more durable than Teflon coating.
Sulfinert -treated Valves
Sulfinert -treated Needle Valves
◎ All wetted components Sulfinert -treated
◎ maximum working pressure up to 5,000 psig (345 bar)
◎ Working temperature: -28 ~204 (-20℉~400℉)
