Retrofit SCO to 100% PTA Facility

Day & Zimmermann (D&Z) provided engineering, procurement and construction services to convert the existing process to produce 100% PTA. This project is part of a program in which the goal was to improve the PET product for new markets.The project called for the installation of eight major unit operations in three building additions/modifications. High alloy materials were the key to this project, including titanium vessels, piping and instrumentation. The project had a fast track schedule; the target was to have the PTA process operational in 13 months with a total project duration of 17 months.

The goal was to complete the installation of the main technical processes by February 2008, less than ½ of the duration of the industry benchmark for fast track retrofit projects of similar size. Those processes were completed on 2/28/08 and were operational in less than one week, besting the target start up by 3 weeks. Day & Zimmermann completed the project under budget and with zero lost work cases.
