Petrochemical industry refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. As an important part of chemical industry, petrochemical and natural gas industry plays an important role in the development of national economy and is one of the important pillar industries of national economy.

Inspection and analysis of petrochemical products and production process control are the key links to ensure product quality, from raw material analysis to product throughout the production process.

Analyze project

Refinery gas analysis	Sulfide analysis
natural gas analysis	organic oxide analysis
cracking gas analysis	elemental analysis
purity and impurity analysis of olefin and alkane	gas analysis of air separation unit in petrochemical plant
aromatic hydrocarbon analysis	meter calibration (environmentally friendly, combustible, toxic)

 The list shows a typical combination of standard gas components for reference, with concentrations ranging from PPM (10-6) to %(10-2) molar or volume fraction. All components and concentrations can be customized according to the actual analysis requirements. Depending on the characteristics of the final composition, the mixture can be in the gas or liquid phase at pressures of 2 to 100bar.
