Qatar's Ras Laffan Olefins Co (RLOC), a joint venture among Qatofin (45.7%), Q-Chem II (53.3%) and QP (1%), is set to launch its ethylene production plant today, Gulf Times has reported. The company has set up an ethane cracker plant at Ras Laffan, which will process the natural ethane gas from the country's North Field into ethylene for producing various plastic polymers. The project will have a capacity of 1.3m tonnes of ethylene each year, which could be expanded to 1.6m tonnes per year at a later stage, the company said.
