Uhde Inventa-Fischer completes PET MTR plant for Octal Petrochemicals in Oman

Gerald Ondrey

The plant engineering and construction company Uhde Inventa-Fischer (Domat/Ems, Switzerland; and Octal Petrochemicals, the largest PET resin manufacturer in the Middle East and the largest integrated PET sheet manufacturer in the world, successfully commissioned a polycondensation plant for the production of PET for bottle and packaging applications. The two production lines are located at the customer`s company headquarters in the city of Salalah, Sultanate of Oman and have an annual capacity of 550,000 metric tons (m.t.).

Based on Uhde Inventa-Fischer's state-of-the-art, energy-efficient, patented Melt-To-Resin (MTR) technology, the plant enables Octal Petrochemicals to produce top-quality PET resin for the local and global market. In combination with the plant built by Uhde Inventa-Fischer at the same site in 2009, Octal Petrochemicals now has one of the world’s biggest single-site production capacities of 1,000,000 m.t./yr, and the highest accumulation of MTR technology.

Uhde Inventa-Fischer’s scope of supplies includes the know-how license for the MTR technology, the basic and detail engineering, supply of all plant components including utilities and offsites and supervision of the construction and commissioning activities.

The MTR process replaces the cost-intensive solid-state post condensation (SSP) process, thus achieving much lower operating and maintenance costs and a significantly reduced carbon footprint at lower investment cost. Feedstock consumption is also considerably reduced without affecting the high product quality. The MTR process is based on the two-reactor high-viscosity technology developed by Uhde Inventa-Fischer and uses the patented Espree and Discage reactors to ensure production of the required high melt viscosity on a sustained basis.
