Teamwork and trust is essential<br />
for a project of this magnitude.<br />
The rising cost of raw materials<br />
exerts pressure on<br />
manufacturing margins. By<br />
increasing production efficiency,<br />
MAN Diesel & <strong>Turbo</strong><br />
production trains facilitate<br />
even expanding competitiveness<br />
for a leading PTA<br />

ased in Dalian, China, the Hengli<br />
Group is one of the world’s major<br />
manufacturers of terephthalic<br />
acid (PTA), one of the key chemicals used in<br />
making plastics and textiles. Recently, the rising<br />
costs of raw materials have squeezed margins<br />
to the point that some of the company’s<br />
competitors have struggled to stay profitable.<br />
The Hengli Group, however, has managed to<br />
buck that trend. One of the key reasons for this<br />
business resilience is its decision to use MAN<br />
Diesel & <strong>Turbo</strong> production trains to upgrade<br />
the efficiency of its manufacturing facilities in<br />
Dalian. “With the Hengli Group as one of our<br />
major partners, we’ve entered the league of<br />
mega PTA plants,” says Dr. Lothar Wallscheid,<br />
VP Basic Industry segment at MAN Diesel &<br />
<strong>Turbo</strong>. “For the Dalian facility, we initially developed<br />
four machinery trains that became<br />
operational in 2013. As requirements grew,<br />
Hengli ordered another two identical trains –<br />
so far the world’s largest of their kind.”<br />
“Our trains are the beating heart of PTA<br />
production for Hengli,” adds Marc Groß from<br />
MAN Diesel & <strong>Turbo</strong>’s onsite team. “The train<br />
consists of a compressor that powers the production<br />
reactor, an axial expander used to recover<br />
energy from the production process, as<br />
well as a steam turbine and engine generator<br />
to produce electricity powering the plant.”<br />
Hengli’s PTA production facilities are of<br />
particular strategic importance to the company,<br />
because around 50% of the manufactured<br />
