Petrochemical Sector

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

PROCESS CONTROL AND EFFECTIVE WATER MANAGEMENT

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.
