Who can tell me what a petroleum chemist really does?

There are too many petroleum testing items, because there are many petroleum products, and different petroleum product testing items are different. Let me give you a general description, hoping to help you!

First of all, what chemists should do is sampling, including raw material sampling and production process sampling. There are also different sampling methods, such as using sampling tubes and opening valves, which means taking samples back to the laboratory for testing.

For testing items, most petroleum products will test micro-water, open flash point, closed flash point, kinematic viscosity, mechanical impurities, surface tension, density, gas phase analysis and so on.

Second, the current laboratory testing level is high, and most of them are instrument testing. All the above instruments are tested by special instruments. The relatively large instruments include gas chromatograph, liquid gas chromatograph, atomic absorption spectrometer and mass spectrometer.

Three, in theory, the duty of the petroleum laboratory technician is:

1. Inspection of incoming raw materials and observation of raw materials.

2. Detection of central control.

3. Factory product inspection.

4. Fill in the daily inspection records.

5. Observe and analyze product samples.

6. Configuration and calibration of laboratory standard titration solution.

7. Collation and archiving of laboratory data.

8. Maintenance of test instruments.

Quality inspection methods for petroleum chemists;

First, the existing quality inspector certificate

Food inspector certificate, fiber inspector certificate, boiler inspector certificate, pressure vessel inspector certificate, pressure pipeline inspector certificate, elevator inspector certificate, tower crane inspector certificate, water quality inspector certificate, large amusement facilities inspector certificate, etc.
