What we do


oil and gas refinery

Comprehensive services for crude oil refining, natural gas processing and purification, sulphur recovery, gas-to-liquids and petrochemical manufacturing and the marketing and distribution of hydrocarbon products.

Navigating the complex downstream hydrocarbons landscape

As part of the WorleyParsons Group, our consultants tap into the 60 years’ experience WorleyParsons has in downstream hydrocarbons activities to support the development, expansion and modernisation of crude oil refineries, implementation of environmental protection initiatives and the manufacturing, marketing and distribution of hydrocarbon products.

Increasingly, we support modernsation projects that enable our clients to maintain plant efficiency, throughput and margins in the face of increasing sulphur production from heavy, sour feedstocks, as well as innovative, cost-effective and safe solutions to meet government mandates for clean fuels.

We have supported the design of more than 600 sulphur recovery plants  that meet the most stringent environmental standards. We offer a complete range of sulphur management and recovery technologies including:

  • Standard and oxygen-enriched technology

  • Tail gas technology

  • Sub-dew point processes

  • Bulk handling and transportation

Advisian also has proven capacity to support gas-to-liquids projects and an extensive range of petrochemical facilities, spanning the full project lifecycle.
