The petrochemical caviar, is the second largest petrochemical industry in the world (after ethylene). 92 million tons of propylene will be released in 2014.

Polypropylene with a share of 66% in the value chain of this substance has the largest share in the consumption of this product in the world. Other key products, such as 8% propylene oxide, acrylonitrile 7%, acrylic acid 4%, kiumene 4%, 2% ethylene hexanol, 4% second to sixth place in propylene consumption. Butanol and isopropanol also consume 3% and 1% at next positions.

The production processes of this product are typically in two categories

  • Low efficiency (Steam cracking and recovery of refinery streams in FCC / RFCC / DCC units)
  • High efficiency (propane-propylene conversion (PDH), catalytic conversion of methanol to light olefins (MTO / P), and conversion of ethylene and butylene to this product (Metathesis))

Are divided. Given the increased demand for this product over the past years, multinational companies have focused on the development of high-efficiency processes because low-yielding methods alone are not the answer. Two methods of converting propane to propylene (PDH) and catalytic conversion of methanol to light olefins (MTO / P) are taking place with serious and significant speed in China, with some delays in the North American region.

The Middle East region is in fourth place, producing 8 million tons of propylene per year from the northeastern Asia (China, South Korea, Japan and Taiwan), the EU and North America. Why!

The Center for Value Chain Studies believes that the Middle East region and, of course, Iran’s dear producers of this product are seriously lagging behind other parts of the world, which is expected to be seriously addressed in the years to come.

At present, the nominal capacity of this product of our beloved country is 1 million 115 thousand tons per year, all of which is based on low-efficiency methods. Studies at the Center for Value Chain Studies show that 95% of propylene produced in the country is made up of polypropylene and only 5% of it is converted into ethyl acetate in the Shazand Arak Petrochemical Complex. While other valuable products in the value chain of this strategic substance are not produced in the country for a variety of reasons, including lack of this product.

Considering the existence of diverse sources (gas and liquid) and the dispersion of locations that are capable of developing the petrochemical industry in our beloved Iran, the Center for Value Chain Studies believes that precise studies should be conducted on selecting the appropriate process for the production of propylene in the country.
