SINGAPORE, July 26 (Reuters) - Oil trader Concord Energy is seeking to build a multi-billion dollar, 150,000 barrel-per-day (bpd) refinery in Singapore, less than two months after its plans for a smaller condensate splitter were shelved, sources said on Thursday.

"Plans are under way now to build a specialised refinery on the same plot of land which was originally picked for the previous project on Jurong Island," a source familiar with the project said.

It is still unclear how quickly the new oil facility will start construction, the source said, adding that the privately owned, Singapore-based company is in the process of submitting plans on the new project to the Economic Development Board (EDB) for approval.

Concord Energy and the EDB declined to comment when contacted. ((Reporting by Jiwon Chung and Luke Pachymuthu, editing by Neil Chatterjee; + 65 6870 3082, Luke.Pachymuthuzreuters.com))
