      In order to verify the product specifications of the blended MS & HSD in the header, it is
      envisaged to install NIR and ASTM analysers in the offsite area near to the respective
      headers.
      The analyser system shall be a part of the blending automation system (supplied by others)
      consisting of blend streams,field instruments,DCS and blend ratio controller(BRC).
      This tender describes the complete scope of work for the analyser vendor.
      Presently MS blending is carried out in 12" header in PH5 area. The header consists of eight
      component streams, a static mixer and a run down line to tank. Analyser sample tapping and
      return line shall be made available after the staic mixer. Liquid dye injection is carried out
      before the static mixer.
      Header pressure is 0.5 to 2.0 Kg/cm2 and temperature 30 to 40 deg C
      On-line analysers are required to continuously track the quality of blended product so that
      corrective action is taken at the earliest to change the blend ratios to obtain on spec. product.


3.1   Blend composistion for MS
      For MS, there are eight streams coming from CCU(2),FCCU,CRU,Naphtha rundown ex plant,
      Naptha ex TK403/404, Reformate ex TK 524/529, MTBE ex TK 358.
      The anticipated production of total Euro-IV MS shall be 500 TMT/A.

        classification, for their terminations. In addition, 'IS' and 'non IS' circuits if used
        shall be segregated and an 'IS' ground provided inside the Analyser, where
        applicable.
8.6.9   Utility other than Instrument air if required is not available at site and should be
