PTA PRODUCTION
Dow’s METEOR™ EO/EG technology
Designed to produce purified EO, EG or purified EO and EG as an integrated process. The METEOR™ Process, which stands for the Most Effective Technology for Ethylene Oxide Reaction, changed the competitive landscape by combining process simplicity, safety and excellent catalyst technology in one design. This helps deliver a major reduction in capital requirements as well as operating and fixed costs, further resulting in:
- Up to 20% reduction in major equipment
- Up to 40% reduction plot plan size
- Up to 50% reduction in control valves
- Up to 40% reduction in flow elements and up to 30% reduction in safety valves
Dow’s EO-only process, referred to as the METEOR™ HEXTEO Process, for making EO Derivatives helps customers recover over 99% of the EO produced in their reactor as high-purity EO.
Case Study: Enabling more efficient ethylene oxide production
Learn how a typical EO/EG plant can reduce 60,000 MT of CO in a 3-year catalyst life cycle with Dow’s METEOR™ EO-RETRO 2000 Catalyst.
News Release: Dow collaborates with PETRONAS
PETRONAS commits to carbon reduction in support of Official Carbon Partnership between Dow and International Olympic Committee (IOC).
LP OXO Alcohol Production
Dow’s low pressure LP OxoSM technology
Is the world's leading process for the production of oxo alcohols from olefins. This process can help achieve higher yield from raw material as well as reduced CAPEX, energy use, and environmental impact. LP OxoSM Technology is compatibility with a variety of feedstocks to allow for flexible production of a broad range of products based on industry dynamics.
To date, this proven process technology has been adopted in 55 projects across 15 countries, representing a majority of the world's oxo alcohols capacity licensed over the past 45 years. LP OxoSM Technology was awarded the Kirkpatrick Chemical Engineering Award, and NORMAX™ Catalyst, used within the oxo production process, earned an R&D 100 Award as well. Dow and Johnson Matthey Davy Technologies Limited continue to innovate the highly flexible LP OxoSM Technology.
Products commonly produced using LP OxoSM Technology:
- 2-ethylhexanol (2EH) for coatings and plasticizer applications
- Butanol for coatings, adhesives, and solvent applications and derivative manufacturing
- Mixed butanols for fuel applications
- Octanol (C8) for block co-polymers
- Aldehydes for oxo acids (C7-C9)
- Higher molecular weight plasticizer alcohols, such as C9 for isononyl alcohol (INA) and C10 for 2-propyl heptanol (2-PH)
- Detergent alcohols (C11-C14)
Technology for producing C7-C9 oxo acids is also available from Dow.
Alcohol production resources

Read about the first license of LP Oxo™ INA Technology and the China-based company Zibo Qixiang Tengda Chemical Company who will be the first to use this process.
COMPRESS™ purified terephthalic technology (PTA)
Jointly licensed by Dow and Johnson Matthey Davy Technologies Limited, is a streamlined process using conventional chemistry and a breakthrough combination of pressure filtration, solvent recovery and integrated water recycle processes to produce PTA.
The process, typically used as a feedstock for polyester resins, helps:
- Reduce investment cost by up to 15% and process footprint by up to 25%
- Lower operating costs by up to 20% due to lower energy and water consumption
- Minimize environmental impact due to lower emission to the atmosphere or to the water stream
The technology is also available for plant retrofits.
