Petrochemical analysis is a key link to ensure petroleum refining, chemical production, oil storage and transportation, and environmental compliance. The general instrument configuration needs to cover the three dimensions of oil physical and chemical properties, pollution and impurities, and gas analysis to form the whole process detection capability from raw material entry to finished product delivery. The following solutions are based on the typical needs of the petrochemical industry and take into account the characteristics of routine testing, professional analysis and intelligent IoT.

Configuration ideas and goals

1. Whole process coverage: from crude oil entering the factory, refining and processing to finished oil leaving the factory, key indicators such as viscosity, flash point, distillation range, moisture, sulfur content, and particle pollution are detected.

2. Multi-scene adaptation: to meet different working conditions such as laboratory precision analysis, on-site rapid sampling, and online continuous monitoring.

3. Intelligent interconnection: Data is directly connected to the MES/operation and maintenance system to achieve automatic generation of trend analysis, early warning and compliance reports.

4. Standard compatibility: Built-in and supports mainstream standards such as GB, ISO, ASTM, SAE, etc., to ensure authoritative and comparable test results.

Core instrument configuration list and function positioning

1. Oil physical and chemical properties analysis series

It is used to evaluate the basic properties and grades of oil, and to guide process control and quality judgment.

Rotational viscosimeter: Determination of the kinematic viscosity of liquid petroleum products at a specific temperature, evaluation of lubricating oil grades, fuel flow analysis

Flash point tester (closed/open): measures the flash point of gasoline, diesel, lubricating oil, etc., and evaluates the evaporation tendency and safety

Freezing point/pour point meter: measure the temperature at which the oil loses its fluidity to ensure low temperature storage and transportation

Acid value tester: Determine the acid content of oil products, monitor aging and corrosion risks

Automatic distillation range tester: measures the distillation range of fuel oil, reflecting evaporation characteristics and component distribution

2. Oil contamination and impurity detection series

Used to monitor oil cleanliness and harmful impurities, prevent equipment failure and environmental risks.

Oil particle counter: detects particle size and quantity, and assesses NAS/ISO pollution levels

Karl Fischer moisture meter: Determination of Trace Moisture in Petroleum Products and Chemical Reagents

Sulfur meter: Determination of total sulfur content, monitoring of desulfurization process and environmental compliance
