What is the use of petroleum sediment？

Petroleum residues (such as residual oil, sludge, etc.) have diverse applications in industrial and environmental protection fields, with their utilization value and technological development outlined as follows:

‌1. Industrial Applications‌

‌Fuel Oil & Chemical Feedstock‌:
Through technologies like fluidized bed hydrocracking (300-400°C, 1-10 MPa), residual oil can be converted into light oil products (e.g., diesel, naphtha), with harmful elements like sulfur and nitrogen removed, achieving a utilization rate of over 90%.

‌Road Asphalt‌:
The viscous fraction after distillation serves as high-quality asphalt material for highways and airport runways (e.g., Beijing Daxing International Airport). Sinopec’s Donghai asphalt technology holds a 75% market share in China.

‌Construction Materials‌:
Oil shale residue can be used as cement filler, lightweight concrete aggregate, or ceramic raw material to reduce production costs.

‌Petroleum Coke Production‌:
Residual oil processed via coking yields petroleum coke, used in steelmaking, aluminum electrolysis, and anode materials for new energy batteries.

‌2. Environmental Protection & Resource Utilization‌

‌Gasification for Hydrogen‌:
China employs heavy residual oil from refineries as feedstock, converting high-carbon waste into hydrogen through gasification, achieving "waste-to-resource" transformation.

‌Activated Carbon Manufacturing‌:
Carbon from oil residues, after carbonization and activation, produces highly adsorbent activated carbon for water and air purification.

‌Waterproof Materials‌:
Modified asphaltenic components are used in waterproofing membranes and coatings to enhance resource efficiency.

‌3. Environmental Challenges & Solutions‌

‌Traditional Disposal Issues‌:
Landfilling or incinerating residual oil risks soil, groundwater, and air pollution (e.g., sulfur dioxide emissions).

‌Modern Solutions‌:
China’s fluidized bed hydrocracking technology processes 2.6 million tons of residual oil annually, significantly cutting carbon emissions and solid waste.

‌4. Specific Applications of Sludge‌

‌Oil Quality Indicator‌:
Sludge content (e.g., insoluble heptane aggregates) is a core parameter for evaluating oxidation resistance in insulating and lubricating oils (per ASTM D4310).

‌Equipment Monitoring‌:
Dynamic changes of sludge in transformer oil can predict equipment aging.

‌Conclusion‌: Petroleum residues achieve high-value utilization via hydrocracking, coking, and gasification, mitigating environmental risks while advancing industrial and new energy development.

SH6531 Petroleum precipitate tester is according to the People's Republic of China standard GB/T6531 "Determination of precipitate in crude oil and fuel oil" and ASTMD 473 , according to GB/T6531 standard to determine the content of precipitate in crude oil and fuel oil.

This instrument is a double structure, can carry out two samples at the same time test.
