APPLICATIONS FOR PETROCHEMICAL INDUSTRY

ONLINE AND INLINE ANALYZERS AND SENSORS FOR PROCESS AUTOMATION

Explosive, corrosive and partly very hot or toxic – those are the characteristics of typical petrochemical process liquids. Whether offshore, in the refinery or petrochemical factory, suitable measuring systems must be able to handle such media in a robust and sustainable stable manner. Apart from that, correct process control must be ensured under even the harshest environmental conditions. E.g. in explosive areas or salty atmospheres. The use of the LiquiSonic® measuring technology and its easy integration into existing systems, allows considerable improvements of system utilization, process safety and product yield with relatively low project costs.

Tipical Applications

Concentration measurement and product quality

• Quality determination (ethylene oxide)

• Water in diesel (Nox reduction)

• Water content in various fuels

• Solvents (methanol, ethanol, etc.)

• (Bio)ethanol in petrol

• Cetane number of diesel

• Octane number of fuels

• Vegetable oils in heating oil

• Liquid gases (methane, propane, butane, etc.)

• Used oil in heavy oil

Phase separation

• Fuels / water

• Oil / salt water

• Glycerine / bio diesel

• Gas / liquid phases

• Raw oil preparation / Water Cut Analyzer

• Fuels and water infiltration

Gas scrubbers

• MDEA (piperazine) / water

• Caustic soda sodium chloride and carbonate / water

• Potassium carbonate potassium hydrogen carbonate / water

Alkylation (HF, H2SO4)

• Typical measuring task:

• HF / H2SO4 concentration: 80 – 95 wt%

• Water concentration: 0 – 10 wt%

• ASO (acid soluble oil) concentration: 0 – 10 wt%

Safety monitoring

• Detection of incursions into waste water

• Glycol incursion from heat exchanger into heavy oil

• Use of measuring technology in peripheral processes, such as heat exchanger, gas washer, blending, desalination

The quality and concentration of different liquid gases often constitute a problem for users. The search for a robust, drift-free measuring device in the Ex area, which logs the data and moreover precisely detects and forwards fluctuations and range exceed.

For example, foreign substances and concentration fluctuations in the ethylene oxide (EO) quality are to be identified in due time.

User benefits include

• Optimal plant control through online and real-time information about process states

• Maximized process efficiency

• Increased product quality

• Reduced lab costs

• Immediate detection of process changes

• Energy and material savings

• Instant warning of irruptions in the process

• Measure in Water or process liquid

• Repeatable measuring results
