Fully automatic online oil water quality automatic monitoring instrument

OIL5000BType is a product developed by our company, which can automatically sample, extract, filter, measure, and discharge waste. It is used to measure the oil content in seawater, surface water, domestic sewage, and industrial wastewater. It is mainly used in petroleum and petrochemical production monitoring, various environmental monitoring automatic stations, enterprises with sewage discharge, sewage treatment plants, and other units.

1Suitable standards:

National Standard of the People's Republic of China "HJ637-2012 Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared Spectrometric Method"

2Technical principle:

According to HJ637-2012 standard, CCl4 is used to extract oil substances from water, and the total extract is determined. The extract is adsorbed by magnesium silicate to remove polar substances such as animal and vegetable oils, and then petroleum is determined. The total extract and petroleum content were calculated based on the absorbance A2930, A2960, and A3030 at spectral bands with wave numbers of 2930 cm-1 (stretching vibration of C-H bond in CH2 group), 2960 cm-1 (stretching vibration of C-H bond in CH3 group), and 3030 cm-1 (stretching vibration of C-H bond in aromatic ring), respectively. The content of animal and vegetable oils is calculated based on the difference between the total extract and petroleum content.

3Main performance characteristics:

• Fully automated monitoring: including automatic sampling, quantification, extraction, filtration, measurement, automatic waste cleaning, and data storage;
• Automatic continuous measurement: The instrument is set up and can work continuously for 72 hours;
• Remote control: Remote control operations and transmission of measurement data can be achieved through the Internet or WIFE;
• Three wavenumber infrared photometry measurement: ensures measurement accuracy and meets national standards;
• *The three-dimensional side stirring extraction system provides more complete and efficient extraction, solving the problem of insufficient extraction;
• Health and safety: Extraction and other operations do not require the involvement of analysts, eliminating andCCl4Contact;
• Advanced filtration device replaces the function of anhydrous sodium sulfate, effectively removing water and impurities;
• The extraction system uses fully corrosion-resistant and non oleophilic PTFE materials, and operates a cleaning process to minimize the cross contamination of high and low concentrations to the greatest extent possible;
• Main technical indicators:
• Detection limit: 0.05mg/L
• Repeatability: ≤ 1% (tested 11 times with 20-100mg/L oil standard sample)
• Accuracy: ≤± 5%
• Linear correlation: ≥ 0.999
• Wavelength repeatability: ± 1 cm-1
• Extraction efficiency: ≥ 90%
• Net weight of the host：28kg
