How does propane dehydrogenation work?

Reference Definition by Wikipedia: Propane Dehydrogenation (PDH) converts propane into propene and by-product hydrogen. The propene from propane yield is about 85 m%. Reaction by-products (mainly hydrogen) are usually used as fuel for the propane dehydrogenation reaction.

What is a PDH plant?

The Propane Dehydrogenation Plant (PDH) in Tobolsk is the largest among dozens of petrochemical plants built by Tecnimont in Russia starting from the thirties of the last century (the first plants were built by Montecatini and Montedison).

When propane undergoes dehydrogenation What is the product?

When propane undergoes dehydrogenation, the product is propene. The structural formula for propene is CH2=CH−CH3.

What is the price of propylene?

Global price of propylene 2017-2021 Globally, the average price of propylene amounted to some 778 U.S. dollars per million metric ton in 2020. By July 2021, the average price of propylene had increased to approximately 1,048 U.S. dollars per metric ton.

Who founded propylene?

Isotactic polypropylene was discovered in 1954 by Italian chemist Giulio Natta and his assistant Paolo Chini, working in association with the Montecatini Company (now Montedison SpA). They employed catalysts of a type recently invented by the German chemist Karl Ziegler for synthesizing polyethylene.

What is oleflex?

The UOP* Oleflex* process is catalytic dehydrogenation technology for the production. of light olefins from their corresponding paraffin. An Oleflex unit can dehydrogenate. propane, isobutane, normal butane, or isopentane feedstocks separately or as mixtures. spanning two consecutive carbon numbers.

Is LPG and propane the same thing?

Generally, propane and liquefied petroleum gas (LPG) mean the same thing. All are flammable hydrocarbon gases with the same chemical formulae categorized as LPG. The slight difference is that LPG contains propane, but propane is one of the LP gases.

Is propane considered green energy?

Propane was approved as an alternative clean-burning fuel in the National Energy Policy Act of 1992 and the 1990 Clean Air Act. Propane was listed because it is a simple three-carbon alkane gas with a relatively low amount of waste products when combusted.

What is the Catofin® technology?

The CATOFIN® technology is a unique process for the production of olefins, such as propylene (from propane) and iso-butylene (from iso-butane). Lummus Technology has exclusive worldwide licensing rights to this technology. The catalyst is produced by Clariant, a leading company in the development of process catalysts.

What is Catofin catalytic dehydrogenation?

The Catofin catalytic dehydrogenation process features a parallel adiabatic fixed-bed reactor system that can be designed for the production of propylene from propane. The process operates at optimum reactor pressure and temperature to maximize conversion of propane for a high yield of propylene.

Why use Catofin for conversion of paraffins to olefins?

Due to its superior thermodynamic operating conditions of vacuum and lower temperature for reactors, CATOFIN provides the highest conversion and selectivity for conversion of paraffins to olefins. Even when co-producing propylene and isobutylene, high conversions can be maintained.

Why choose Catofin 311?

Thanks to its extraordinarily high reliability and productivity, CATOFIN delivers excellent production output annually compared to alternative technologies. For a typical 600 kta PDH unit, this innovation translates to a potential of up to $20 million of additional productivity over the lifetime of the CATOFIN 311 catalyst.
