"TPC Group and SI Group have a longstanding partnership that extends beyond 25 years," said Frank Bozich, SI Group President & CEO.

We are committed to the successful integration of this business, as it's a vital component of our growth agenda."

"In 2016, TPC Group has made great strides in our earnings and cash improvement plan, or ECIP, targeted to deliver more than $100 million of year over year improvement," said Ed Dineen, TPC Group Chairman, President and CEO. "One key element of this plan was the sale of non-core assets of which the Baytown assets were the most leveraging components. While the Baytown assets and people have consistently delivered value to TPC Group, the proceeds of this transaction will allow us to strengthen and grow our core C4 processing, Performance Products and Fuels Octane businesses. On behalf of the entire senior leadership team, we want to extend our sincere appreciation for the commitment, dedication, focus and safe operations by the Baytown employees."
