Propane dehydrogenation (PDH) is a process that converts propane to propylene
Propane dehydrogenation (PDH) is a significant industrial process that converts propane into propylene. This process is used to manufacture polypropylene, acrylonitrile, and other chemicals. Propylene is a crucial component in the production of plastics, automotive parts, packaging materials, and textiles.
The PDH process involves preheating propane, recycle propane, and hydrogen to a temperature between 500°C and 700°C. The heated feed is then introduced into a moving or fixed-bed reactor at near-atmospheric pressure. This reaction converts propane into propylene through dehydrogenation, which involves the removal of hydrogen from the propane stream. The choice of catalyst depends on the specific process, with platinum or chromium oxide-based catalysts being commonly used.
The development of shale gas supplies has made PDH a preferred method over traditional energy-intensive processes like naphtha cracking. PDH offers a more efficient and selective approach to producing propylene, which is in high demand globally, particularly in the automobile sector and for manufacturing bottle caps, fabrics, and packaging materials.
One example of a PDH facility is the Inter Pipeline plant in Alberta, Canada, which converts 20,000 barrels per day of locally produced propane. Another notable PDH/PP operation is Heartland Polymers, the only single-site PDH/PP complex in North America. Heartland Polymers has been providing a reliable on-site source of feedstock for polypropylene production since 2022.
The increasing demand for plastics and the necessity to optimize natural gas resources have contributed to the widespread adoption of the PDH process. With advancements in technology, PDH has become a competitive and sustainable method for producing propylene, driving the petrochemical industry forward.

PDH units are large-scale manufacturing units requiring substantial investments
Propane dehydrogenation (PDH) is a process used to produce propylene, a key feedstock in the petrochemical industry. Propylene is used to make polypropylene, a plastic that is in high demand for consumer goods such as kitchen utensils, food containers, and car batteries. As the demand for propylene-based products continues to grow, the PDH market is also expanding.
PDH units are large-scale manufacturing units that require substantial investments for construction and installation. The PDH process involves converting propane into propylene, which is then used to produce polypropylene. This process requires a significant amount of heat and electricity, resulting in high energy consumption. Therefore, small-scale enterprises often face challenges in adopting PDH technology due to the required infrastructure and costs.
The benefits of PDH technology include its high yield and efficiency. With a yield of 85%, PDH has the highest propylene output compared to other on-purpose propylene production technologies. This contributes to its popularity among chemical industries, particularly in countries with a growing demand for plastic-based packaging, such as China and India.
One notable example of a PDH unit is the Heartland Polymers facility in Alberta, Canada. Heartland Polymers is the only single-site PDH/PP complex in North America, providing a reliable source of polypropylene for its customers. The construction of this complex involved over 25 million hours of labour and spanned more than a decade, demonstrating the significant investment required for PDH units.
The future of the PDH market looks promising, with continuous research and development leading to technological advancements. By 2027, PDH is expected to contribute 32% to the propylene production that fills the supply/demand gap. This growth is driven by the increasing demand for propylene in the consumer goods industry and the preference for on-purpose propylene solutions.

PDH is the most efficient propylene production technology
Propylene is a crucial petrochemical feedstock and a fundamental building block for many chemicals. The global demand for propylene is rising, and the market is expected to experience solid growth in the coming years. However, the gap between market demand and the ability of traditional sources to meet this demand has been widening since 2011. This widening gap has led to the development and adoption of on-purpose propylene production technologies, with propane dehydrogenation (PDH) being the primary on-purpose technology.
PDH is a simple process that involves converting propane feed into propylene as the primary product, with the option to utilise the byproduct, hydrogen, for fuel or export. PDH has the highest propylene yield among on-purpose technologies, at 85%. This high yield translates to significant economic advantages, as every tonne of propylene produced can save up to $10 in production costs compared to competing technologies. Additionally, PDH technology, specifically Oleflex, offers a 15-20% reduction in capital expenditure due to its design simplicity and high performance.
The advantages of PDH technology are evident in the success of Heartland Polymers, North America's only single-site PDH/PP complex. Heartland Polymers' PDH plant has been providing a reliable on-site source of feedstock for their polypropylene production, demonstrating the efficiency and reliability of PDH technology. The construction of this complex involved over 25 million hours of labour and effort, spanning more than a decade, showcasing the significant investment and commitment behind this technology.
The adoption of PDH technology is expected to grow, with projections indicating that by 2027, PDH will contribute 32% of the propylene production filling the supply/demand gap. The efficiency of PDH in propylene production, coupled with the increasing demand for propylene in plastic production, particularly in developing nations, underscores the importance of this technology in the petrochemical industry. As companies seek to address the widening propylene supply/demand gap, PDH technology offers a compelling solution with its high yield, cost-effectiveness, and reliability.
