Petroleum liquid feeds, commonly referred to as PLF, are liquid fuels derived from petroleum sources such as crude oil, natural gas condensates, and oil refinery streams. PLF production involves processes such as fractional distillation and catalytic cracking to break down crude oil into various hydrocarbon fractions of differing molecular weights. The lighter hydrocarbon fractions including naphtha and kerosene are most suitable for use as PLF due to their liquid physical state at ambient temperatures.
Properties and Composition of PLF
Petroleum liquid feeds are complex mixtures of hydrocarbon molecules ranging from 5 to 12 carbon atoms per molecule. The exact chemical composition of a given PLF depends on the petroleum source and production process but PLFs generally contain a variety of paraffins, isoalkanes, olefins, naphthenes, and aromatics. Key properties of PLFs include high energy densities, low pour points allowing use in cold climates, ease of transport via pipelines and tankers, and widespread availability from existing oil infrastructure and reserves. Typical fuel properties of PLFs are a flash point above 38°C, sulfur content below 0.5% by weight, and net heating value between 42-45 MJ/kg.
Applications of PLF in Energy and Chemical Production
Due to their energy density and liquid state, Petroleum Liquid Feedstock see wide application as cost-effective fuels and feedstocks. Major uses of PLF include:
- Power Generation: Light fractions of crude oil are frequently used as auxiliary or backup fuels co-fired at coal, natural gas, or biomass power plants. PLFs provide valuable fuel flexibility to complement intermittent renewable energy.
- Refineries: Naphtha cracker units at oil refineries utilize light naphtha and kerosene fractions as feedstocks to produce olefins, aromatics and other petrochemical building blocks.
- Transportation: Countries with limited pipeline infrastructure sometimes utilize PLFs as a diesel blend component or shipping fuel. PLF use helps diversify fuel supply in remote areas.
- Synthetic Natural Gas: Autothermal reforming of naphtha or other PLFs with steam produces a synthetic gas consisting mainly of hydrogen and carbon monoxide. This synthetic gas can undergo additional processing to create pipeline-quality renewable natural gas.
Petroleum Liquid Feeds as a Transition Fuel
As concerns grow around the environmental impacts and long-term sustainability of coal and conventional oil reserves, PLFs represent a practical transition option. Using existing oil and gas infrastructure helps accelerate the energy transition while alternative renewable technologies are further developed and deployed at large scale. Specific advantages of PLFs in this context include:
- Established Supply Chains: Vast global reserves of crude oil and natural gas ensure stable long-term supply of PLF feedstocks via mature production and distribution networks.
- Carbon Capture Potential: Autothermal reforming of PLFs produces concentrated CO-rich syngas suitable for carbon capture and storage or utilization. Integrating CCS technology allows "negative emissions" operations.
- Fuel Diversification: Displacing coal and fuel oil with lower-carbon PLFs at power plants improves emissions while maintaining base load energy supply. PLFs provide stable backup for intermittent renewables like wind and solar.
- Technology Leveraging: Oil refineries, gas processing plants and other infrastructures built over decades for fossil fuels can be partly retooled to produce lower-carbon synthetic fuels and chemicals from PLF feedstocks.
