Our Indian subsidiary Environnement SA India Pvt. Ltd won the tender of Indian Oil Corporation Limited, Bongaigon, Assam to install 2 Dilution based monitoring systems to measure continuously multiple parameters in the Casoline's plant chimney: SO₂, NOX, CO, and CO₂, integrated into a Safe Area Analyzer Shelter. Part of the furniture are also the particulate monitors PCME STACK 602.

In parallel, 2 other gas emissions monitoring systems for SO₂ and NOx as well as dust monitors PCME STACK 602 have been installed in the FCCU plant.
We would like to thank our partners - Technip India Limited and L&T, Baroda - for their trust and confidence.

About Indian Oil Corporation | Bongaigaon Refinery

It two Crude Distillation Units (CDU), two Delayed Coker Units (DCU) and a Coke Calcination Unit (CCU) with a processing capacity of 2.35 MMTPA of crude oil. The first CDU with a capacity of 1 MMTPA was commissioned in the year 1979. The capacity was further increased to 1.35 MMTPA in 1986. An LPG Bottling Plant with a capacity of 44,000 MTPA was also commissioned in the year 2003.

Presently the refinery produces a wide range of petroleum products namely LPG, Naphtha, MS, SKO, HSD, LDO, LSHS, LVFO, RPC, CPC, Needle coke and solvents (Petrosol and Bonmex-II) by processing Assam Crude and Ravva Crude (from the Ravva oil fields of Krishna Godavari Basin). Bongaigaon refinery has also undertaken special endeavours towards environment protection and conservation. The refinery has developed an ecological park and a pond surrounding it containing 65,000 cubic meter of water, through which the storm water drains of the plant are routed for final discharge. Another natural pond with a capacity of 30,000 cubic meter of water has developed into an environment-friendly park-cum-pond for migratory birds. In addition, a rain water harvesting system has been installed in the Bongaigaon township complex and the installation of solar water heating systems (SWHS) and solar photovoltaic systems (streetlights) is underway.

In recognition of its green initiatives, Bongaigaon refinery has been a recipient of numerous prestigious awards, the latest being the National Award for 'Prevention of Pollution' from the Ministry of Environment and Forests on September 16, 2010. The award acknowledges the Refinerys outstanding contribution in environmental conservation and creating environmental awareness in the Bodo Territorial Autonomous District region of Assam, which is predominantly a tribal dominated area. Bongaigoan Refinery is the countrys first oil Refinery to have won this coveted honour. Last year the Refinery was honoured with the Indira Gandhi Paryavaran Puruskar by the Ministry of Environment, as well as the Greentech Environment Excellence Gold Award 2008 and the Indira Gandhi Paryavarn Puraskar 2006 for its outstanding environment performance.

Focus on the PCME STACK 602 dust monitor: a cross-stack optical system used extensively for compliance measurement in the Power, Steel and Cement industries. With TUV approval for EN 14181 and EN 13284-2, the instrument is primarily used in applications with electrostatic precipitator boilers, calciners and large diameter emission stacks. The PCME STACK 602 can be used in processes where either direct Opacity (and extinction) measurement is required, or dust concentration measurement for specific applications via calibration against the Standard Reference Method.

Traditional Opacity instruments measure the intensity of received light; PCME's patented DynamicOpacity™ Ratiometric Opacity technology instead measures the temporal variation (rate of change) in light, or Optical Scintillation. This offers a significant advantage over traditional Opacity methods, as the ratiometric measurement is unaffected by lens contamination allowing the instrument to operate with lens contamination exceeding 90%, therefore greatly reducing costly process intervention for lens maintenance and servicing.

• Automatic Zero and Span checks to monitor for instrument integrity
• Extended maintenance intervals due to reduced sensitivity to lens contamination
• Sensor lenses are accessed in-situ for lens cleaning, ensuring correct alignment of transmitter and receiver even after maintenance
• Entry and Standard control unit with advanced graphic and user interface screens, features including alarming, graphical trending, data logging, 4-20mA output.
• PLUS control unit option for sensor networking (up to 16 sensor channels) via industry standard Modbus, multiple inputs for external devices (e.g. for Temp and O₂ normalisation)
