Optimizing wa­ter ma­na­ge­ment at petro­che­mi­­cal faci­li­ties.

Petrochemical Sector


In the petrochemical sector production of petrochemicals, plastics and biodiesel requires high process safety and product quality. Especially in the steam-waer cycle as well as in the cooling water and process water, effective monitoring for efficient and trouble free processing is essential. In particular, it is important to minimize product losses and optimize water management.

Any disturbance in water circuits may lead to a total system shutdown, which causes enormous costs. Application specific online measurement technology that quickly and reliably detects contaminants in the water offers enormous advantages and reduces costs.



Types of Water

  • Process water
  • Cooling water
  • Surface water
  • Boiler feed water
  • Condensate return
  • Industrial waste water
  • Discharge control
  • Oil-in-Water
  • High salt concentrations


Avoid high costs by preventing

  • Product losses
  • Losses of heating energy for instance when condensate return is contaminated
  • Additional pretreatment of water for (purified) water cycles
  • Additional treatment of waste water
  • Additional charges for extending discharge limits
  • Additional costs for repair/replacement of damaged equipment

Use of water as a raw, auxiliary and/or operating material in a variety of processes:

  • Process water for heating purposes
  • Process water for cooling purposes
  • As steam to drive turbines
  • As a reaction medium for cleaning

Adequate water management safeguards plant operation

  • Process water that is cost-intensive to produce and to heat
  • Recycling process water and its thermal energy promises considerable savings potential
  • Water quality must comply with purity specifications

Leakages and equipment failures cause contamination of product and of process water

  • Organic contamination may lead to damages in pipes, boilers and heat exchangers
  • Severe contamination may lead to a shutdown of the entire production plant
  • Shock loads will cause severe problems in the downstream waste water treatment

Additionally, the waste water treatment is demanding due to high pollution by chemicals, oils, salts and other contaminants.

Ex-proof equipment for industrial plants (chemical,upstream) 

Ex Zone = explosive gasses, vapors and/or mist are often present. Any spark may cause an explosion.

Online water analyzers with ex-proof housings are installed as close as possible to the process to ensure fast analyses. 

LAR Analysers correspond to international standards and are certified in accordance with IECEx as well as ATEX Directives. 

  • Oil-in-Water (OIW) Analyzer


    LAR's OIW analyzer QuickOIL is a reliable online measurement system for the determination of oil in water. Due to the analyzers' innovative process design the analyzer determines the OIW content directly without dilution or memory effects. Moreover, it is suitable for every kind of oil, fat and grease - a huge advantage against common OIW methods.

    Easy. Fast. Reliable.

  • Certified Housings for Special Conditions

    In petrochemical or chemical plants explosive gasses, vapours or mist can be present. Therefore, LAR offers a wide range of analyzers with tailor made protective housing in accordance to international standards (IEC 60079-14:2007) and regulations (DIN EN 60079-2:2011-11). These stand-alone analyzers do not necessarily require air-conditioned shelters and they are made specifically for the use within hazardous, potentially explosive and corrosive environments.

  • TOC Analyzer for Pure Water Applications


    AR's TOC analyzer QuickTOCpurity is the most reliable measurement system for pure and ultra pure water applications. Due to a special injection loop, the sample is fully protected against contaminations from ambient air. Hence, the QuickTOCpurity reliably detects the TOC level of pure water.

    The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.

  • TOC AnOnline TOC Analyzer


    LAR's TOC analyzer QuickTOCultra is the most reliable measurement system for the roughest waste water applications. Due to an unrivaled injection and oxidation technique, the QuickTOCultra easily handles sticky, fatty, salty, and high-particle samples unlike other TOC analyzers.

    The combustion leader in TOC analysis provides maximum reliability and availability, hence also profitability for its operators.

  • Online COD Analyzer


    LAR's chemical oxygen demand (COD) analyzer QuickCODultra is an outstanding measurement system for fast and clean COD measurements. Unlike traditional COD analysis methods, the QuickCODultra oxidizes water samples without the need of any hazardous chemicals. Due to the patented high-temperature combustion method, the measurement results are free of chloride inteferences. Moreover, the analyzer easily handles sticky, fatty, salty, and high-particle samples.

    Less chemicals. Simple operation. Save money.
