Proven on-purpose and by-product solutions
UOP offers multiple propylene production solutions that can help you better manage feedstock costs.
On-Purpose Propylene from Propane
The catalytic dehydrogenation of propane allows you to participate in the growing propylene market, independent of a steam cracker or FCC unit. The Oleflex process provides a dedicated, reliable, independent source of high-quality propylene to give you more control over propylene feedstock costs.
As the leading on-purpose polymer grade propylene production technology in the world, Oleflex provides the lowest cash cost of production and highest return on investment when compared to competing PDH processes via:
- Lowest operating cost enabled by low feedstock consumption and low energy usage
- Lowest capital cost enabled by the industry’s only continuous process and operation with a highly active and stable catalyst at positive pressure utilizing only 4 reactors.
- Highest reliability enabled by recent design enhancements and the ability to change catalyst on-the-fly without stopping propylene production.
The Oleflex process leverages industry leading UOP heat and mass transfer equipment, process equipment and control systems.
Today there are twenty six C3 and C4 Oleflex units in operation, which is more than twice the number of operating units of the nearest competitor. The same proprietary design is used in the catalytic dehydrogenation of iso and normal butanes to butylenes.
On-Purpose Propylene from Cost Advantaged Feedstocks
The UOP Advanced MTO Process, which integrates the UOP/Hydro MTO Methanol to Olefins Process with the UOP/Total Petrochemicals Olefin Cracking Process (OCP), converts cost advantaged alternative feedstocks such as coal, natural gas and petcoke to light olefins. The process offers a number of benefits:
- Lower light olefin cost of production than conventional routes
- The highest propylene and ethylene yields when compared to competing MTO technologies
- Minimal by-product formation
- A wide range of ethylene and propylene production
- Largest single train capacity and smallest footprint
The Advanced MTO process has been fully demonstrated at the semi-commercial scale by Total Petrochemicals in Feluy, Belgium. The MTO process was first commercially deployed at Wison Clean Energy, Nanjing, China (now Chengzhi), which met all performance guarantees shortly after start-up. Since then, two more MTO units have started up at Yangmei, Linyi, Shandong, China, and Sailboat, Lianyungang, Jiangsu, China. The Sailboat MTO unit is the largest MTO in the world, with total light olefin capacity of 833 kmta. A further nine MTO units have been licensed and are in various stages of design, construction, and commissioning, with several due to start up before 2019.
In addition to its role upgrading C4+ by-product streams into propylene and ethylene in the Advanced MTO process, OCP can be used for by-product upgrading in steam crackers, FCC units and Delayed Cokers.
The UOP Propylene Recovery Unit is the most economic method to separate propylene from propane. It brings together three proven technologies — UOP’s MD distillation trays, High Flux tubing and heat pump compressor system to produce chemical or polymer-grade propylene from refinery by-product streams. Multiple UOP-designed propylene recovery units are in operation around the world, and more than 170 propane-propylene splitters with MD trays are in operation or under construction today.
