The Natural Gas Sampling System 3000 is designated to take a sample stream from a pressurized natural gas source.
The outlet of the sampling system can be connected directly to an analyzer (UT-3000) or the gas can be fed into a special sample bag (Tedlar® bag) and carried to the analyzer.
Tedlar® bags come as accessories with the UT-3000 Mercury Ultratracer.
For measuring mercury in natural gas the pressure of a high pressure sample feed has to be reduced to a suitable low pressure before measurement.
The new NG-SAMPLING SYSTEM-3000 follows a straight forward design.
It integrates a minimum of components. All gas wetted parts in the sample path have been silicon coated. This allows very fast conditioning and low memory effects.
The high pressure sample passes a ball valve ( 1 ). A coated filter ( 2 ) removes particles from the sample.
After that the sample gas passes a heated capillary tubing. Heating compensates the Joule-Thomson Effect caused by pressure drop inside of the capillary. The heater temperature is displayed on the thermometer T1.
The Pressure regulator PR-01 keeps the pressure at outlet of the capillary constant. The pressure is shown on pressure gauge P1 and can be adjusted on PR-01. Excess gas is vented off through flow meter FL1.
With needle valve 3 the combined flow of sample gas to the analyzer and to the vent through flow meter FL2 can be adjusted. If the analyzer samples gas from this stream the flow through FL2 will decrease, but has always to be positive. In case of pressure breakthrough and a following increase of pressure at the low pressure side the safety valve V-03 will open and automatically release the pressure.
With ball valve 1 at Sample IN the sampling system can be isolated from the gas source. The needle valve 3 allows to close the outlet sample flow.
The new NG-SAMPLING SYSTEM-3000 shows a considerable performance improvement compared to conventional models with integrated heated pressure regulator.
