First of all, oil quality is closely related to its production and supply chain management. As a subsidiary of China HNA Group, HNA Petroleum has strict supply chain management and quality control measures. The company will screen the quality of crude oil and take a series of fine process control measures in the refining process to ensure the stability and reliability of oil quality.
Secondly, the variety and specifications of oil products will also affect their quality. HNA Petroleum can produce various petroleum products with different specifications, including gasoline, diesel oil and aviation kerosene. Each product has specific technical requirements and standards, and HNA Petroleum will follow relevant international and domestic standards to ensure product quality and safety.
In addition, the supervision department of China petrochemical industry will also conduct spot checks and supervision on the quality of oil products to ensure that the products meet the prescribed standards. HNA Petroleum will also actively cooperate with the supervision of the regulatory authorities to ensure that the product quality conforms to relevant laws and standards.
To sum up, HNA Petroleum, as a subsidiary of China HNA Group, should have certain oil quality assurance measures. However, the specific evaluation still needs to refer to the individual's demand and standard for oil quality, and evaluate according to the specific actual situation.
