New efficiency for your PTA production business
The basis of polyester fiber production for modern, functional clothing, PTA (purified terephthalic acid) is in constant demand. Our highly efficient compressor trains allow you to boost production without increasing your environmental footprint.
Multiple process streams in one compact unit
Defying conventional logic, our new PTA machinery trains have decreased in size whilst increasing production output.
In 1977, MAN Energy Solutions delivered its first PTA compressor train. Since then, we’ve become the leading supplier of compressor trains to an ever-growing industry. We've achieved this position for good reason and we're working hard to stay ahead of the competition.Our customers can now enjoy the benefits of machinery trains which boast up to 20% higher output without any noticeable increase in compressor size. In fact, we have achieved a weight reduction of over 10%, saving you costs. Each MAN Energy Solutions PTA compressor train is made up of several components, from air compressors to expanders - and we've been working on all of them to increase efficiency.
We take special care to meet individual clients' requirements. Should you have a previously unseen PTA compressor train in mind, we will do our best to help you make your vision become reality.
PTA turbomachinery train components
Each of our PTA machinery trains consists of several components. Our integrally geared radial air compressors are multi-shaft centrifugal compressors. They are used in several industries, with customers enjoying their durability and low operating costs among other benefits. They are at the heart of our trains which are now capable of producing up to 1.5m tons of PTA each year. In our latest PTA machinery trains, these compressors have hardly increased in size despite an increased overall production output of around 20%.
How you benefit:
- Individually selectable impeller speed for optimum flow and costs
- Modular component packages for short delivery periods
- Modular sealing systems
- Maximum driver flexibility
- Intercooling opportunities
Our expanders come in a single- and multi-stage design, in axial or radial blade/impeller configurations. Each of our PTA machinery trains features an integrated expander tailor-made for the requirements of your individual machinery train. Recently, we have been able to achieve higher output with smaller machinery trains. Especially hardy and reliable, our expanders have long been a core component of our ever-improving trains. Typically, our expanders will allow for the following performance:
- Power output of up to 30 MW
- Inlet pressure for PTA expanders up to 20 bar
We offer a wide range of multi-stage steam turbines suitable for mechanical drive applications up to 180 MW. Featuring a variety of design characteristics which allow for optimized turbine configuration, this piece of equipment meets all sorts of challenging process conditions and/or your specific requirements. The modular design concept keeps delivery and costs at competitive levels.
In addition to PTA production, our steam turbine drives are in operation in a range of industries: Refining, chemicals, petrochemicals, fertilizer, air separation, iron and steel and mining.
How you benefit:
- Highest efficiency based on optimized turbine design
- Reduced CO2 emissions
- Highest availability
- Customized for your specific requirements
