(Zawya) -- By 2015, BMI forecasts ethylene and propylene capacities will rise to 16.52mn tpa and 6.55mn tpa respectively, with Saudi Kayan's commercial operation in 2011 set to contribute most to the increase, according to BMI's latest Saudi Arabia Petrochemicals Report. Compared with 2010, total PE capacity will rise 20% to 8.86mn tpa, PP will rise 11% and PS, PET and
PVC capacities will remain unchanged. Ethylene capacity in 2015 is forecasted to be more than double that of 2008 levels, with Jubail and Yanbu the focus of petrochemicals developments.
Technical problems at Sahara Petrochemicals' Al-Waha plant and at Petro Rabigh have adversely
affected PP output. The temporary closures did not affect supplies, which were maintained through
inventories, although BMI expected a negative impact on profitability at the respective plants. On the
upside, NatPet resumed operations at its Yanbu-based 400,000tpa PP complex after completing a
scheduled maintenance 11 days before the 60-day turnaround was due to be completed. The scheduled maintenance aimed to increase the operational rate of the complex, which was started in August 2010 but experienced two shutdowns in H111 due to technical problems and power outages, causing losses of more than US$11mn.
