Worley Comprimo and BASF to deliver integrated gas treatment and SRUs for Budour Tayseer Gas Project

Contract and parties

Worley Comprimo, in partnership with BASF, was awarded the engineering and licensing contract to deliver integrated gas treating technology and Sulphur Recovery Units for the Budour Tayseer Gas Project (BTGP) in Oman. SPETCO has signed an agreement to develop BTGP.

Project output and framework

The project is sized to produce 2 million standard cubic metres per day of sweet gas, 950 cubic metres per day of condensate, and 80 tonnes per day of sulphur pellets. It is intended to supply gas under a design-build-own-operate-maintain (DBOOM) framework to reinforce Oman’s energy infrastructure and support in‑country value.

Scope and technology

The awarded scope is delivered under a single licensor model and includes an Acid Gas Removal Unit (AGRU), Adsorption Unit (AU), Sulphur Recovery Unit (SRU), Tail Gas Treatment Unit (TGTU) and sulphur degassing. The project will utilise BASF’s OASE® purple M hybrid solvent for deep acid gas and selective H2S removal and Durasorb® adsorption to polish gas by removing water and mercaptans in a closed loop.

Execution rationale

Worley Comprimo says integrating specialist gas treating and sulphur recovery teams under one licensor enables more efficient engineering schedules and smoother execution than tendering AGRU and SRU separately. BASF highlights the partnership and the technologies’ combined CAPEX and OPEX efficiencies for removing mercaptans (RSH) and carbonyl sulfide (COS) at low hydrocarbon co‑absorption rates.
