{"cited_by_count":619429,"description":"This cluster of papers focuses on advances in petroleum chemistry and analysis, with a particular emphasis on the characterization of complex petroleum components such as asphaltenes and naphthenic acids. The use of mass spectrometry for detailed chemical analysis, biodegradation studies, nanoaggregation behavior, and the impact of these components on oil sands and heavy oil are also key areas of research.","display_name":"Petroleum Processing and Analysis","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11630","wikipedia":"https://en.wikipedia.org/wiki/Petroleum_chemistry"},"field_id":"16","id":"T11630","keywords":[{"display_name":"crude oil","id":"crude-oil","score":0.2377,"url":"https://openalex.org/keywords/crude-oil"},{"display_name":"asphaltenes","id":"asphaltenes","score":0.6091,"url":"https://openalex.org/keywords/asphaltenes"},{"display_name":"heavy oil","id":"heavy-oil","score":0.267,"url":"https://openalex.org/keywords/heavy-oil"},{"display_name":"petroleum refining","id":"petroleum-refining","score":0.287,"url":"https://openalex.org/keywords/petroleum-refining"},{"display_name":"asphaltene precipitation","id":"asphaltene-precipitation","score":0.7355,"url":"https://openalex.org/keywords/asphaltene-precipitation"},{"display_name":"wax deposition","id":"wax-deposition","score":0.5316,"url":"https://openalex.org/keywords/wax-deposition"},{"display_name":"waxy crude oil","id":"waxy-crude-oil","score":0.6277,"url":"https://openalex.org/keywords/waxy-crude-oil"},{"display_name":"hydrocracking","id":"hydrocracking","score":0.2304,"url":"https://openalex.org/keywords/hydrocracking"},{"display_name":"demulsification","id":"demulsification","score":0.2322,"url":"https://openalex.org/keywords/demulsification"},{"display_name":"petroleum fractions","id":"petroleum-fractions","score":0.4697,"url":"https://openalex.org/keywords/petroleum-fractions"},{"display_name":"asphaltene aggregation","id":"asphaltene-aggregation","score":0.8429,"url":"https://openalex.org/keywords/asphaltene-aggregation"},{"display_name":"asphaltene deposition","id":"asphaltene-deposition","score":0.6765,"url":"https://openalex.org/keywords/asphaltene-deposition"},{"display_name":"vacuum residue","id":"vacuum-residue","score":0.5835,"url":"https://openalex.org/keywords/vacuum-residue"},{"display_name":"demulsifiers","id":"demulsifiers","score":0.569,"url":"https://openalex.org/keywords/demulsifiers"},{"display_name":"heavy oil upgrading","id":"heavy-oil-upgrading","score":0.5889,"url":"https://openalex.org/keywords/heavy-oil-upgrading"},{"display_name":"hydrocarbon composition","id":"hydrocarbon-composition","score":0.3135,"url":"https://openalex.org/keywords/hydrocarbon-composition"},{"display_name":"naphthenic acids","id":"naphthenic-acids","score":0.3288,"url":"https://openalex.org/keywords/naphthenic-acids"},{"display_name":"catalytic reforming","id":"catalytic-reforming","score":0.2259,"url":"https://openalex.org/keywords/catalytic-reforming"},{"display_name":"pour point","id":"pour-point","score":0.2149,"url":"https://openalex.org/keywords/pour-point"},{"display_name":"crude oil composition","id":"crude-oil-composition","score":0.51,"url":"https://openalex.org/keywords/crude-oil-composition"},{"display_name":"API gravity","id":"api-gravity","score":0.3226,"url":"https://openalex.org/keywords/api-gravity"},{"display_name":"wax appearance temperature","id":"wax-appearance-temperature","score":0.756,"url":"https://openalex.org/keywords/wax-appearance-temperature"},{"display_name":"wax precipitation","id":"wax-precipitation","score":0.7053,"url":"https://openalex.org/keywords/wax-precipitation"},{"display_name":"pour point depressants","id":"pour-point-depressants","score":0.5277,"url":"https://openalex.org/keywords/pour-point-depressants"},{"display_name":"vacuum gas oil","id":"vacuum-gas-oil","score":0.394,"url":"https://openalex.org/keywords/vacuum-gas-oil"}],"legacy_keywords":["Petroleum","Asphaltenes","Naphthenic Acids","Mass Spectrometry","Oil Sands","Biodegradation","Nanoaggregation","Wax Deposition","Heavy Oil","Chemical Characterization"],"openalex_id":"https://openalex.org/T11630","source_created_date":"2024-01-23T15:27:11","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1602","url":"/topics/T11630","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11630","works_count":72464,"label":"Petroleum Processing and Analysis","provider":"openalex","revision":"01e4942076f34ae0","taxonomy_revision":"f050b5d4780b1289","title":"Petroleum Processing and Analysis","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36183038094379217","address_version":"morton4x16-v1","coordinates":[3,16,1602,11630],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
