Oil automatic system (autosampler-BSW)

 

This automatic sampling system ( autosampler-BSW) has been designed for sample oils from upstream crude-oils to refined products according to the requirements of the most usual standards : ISO 3171 ; ASTM D 4177 ; IP Petroleum Measurement ( Manual Part VI, section 1 ).

A main benefit of the automatic sampling system ( autosampler-BSW) is to integrate the complete line of features to keep sample integrity e.g.:

  • Large bore by-pass loop isokinetic sampling with large opening size and 2.4 m/s constant velocity as per the API recommendations related to automatic sampling system ( autosampler-BSW).
  • Accurate extractor grab size repeatability assured by positive displacement principle .
  • Sample extracted from process line is directly stored in the sample receiver chamber integrated to the autosampler .
  • Autosampler receiver chamber is equipped with a mixer to prevent stratification of heavier fractions during the sample transfer to the 1 liter portable receiver .
  • The automatic sampling system ( autosampler-BSW) receiver chamber is a floating piston cylinder to suit with split phase crude-oil ; sampling is operated at constant pressure .
  • A feed back to the automatic sampling system ( autosampler-BSW) Control Unit indicates the amount of sample contained inside of the sample receiver and a local indication of level is given by the piston shaft position .
  • Another feed-back free contact is issued to verify that pulses have been transferred to the sample solenoid valve of the automatic sampling system ( autosampler-BSW).
  • The automatic Sampling processing is operated by pilot pulses issued by separate Control Unit for safe or flammable area .
  • Grabs are taken in proportion to flow or time .
  • A permanent comparison between the sample collected in the receiver and the batch volume actually monitored on line is achieved , therefore confirmation that the automatic sampling system ( autosampler-BSW) extracts a uniform grabs in flow or time proportional manner is made .
  • At the end of the automatic sampling , compliance with service factor requirement specified by ISO 3171 is checked and reported

The automatic sampling system ( autosampler-BSW) wetted materials are Stainless Steel 316L with PTFE seals ; the grab rate can be set up to 100 grabs /mn and the sample maximum viscosity acceptable is 8 000 cst .

All electrical parts are ex-proof Class 1 Division 1 Groups C&D (NEC ) or ATEX II 2G EEx dIIB T4.
