The estimated $50 million project calls for the construction of a 130,000-tonne-a-year (t/y) butene-1 facility, which will complement two existing 50,000-t/y butene-1 units at the complex. Project completion is due in 20 months, with engineering expected to take about seven-eight months.

In addition to butene-1, the Petrokemya complex, which came on stream in 1985, also produces benzene, butane, ethane, styrene, light naphtha ethylene, propane, propylene, polystyrene and natural gas butadiene (MEED 2:5:03).
