Propylene can be produced as a by-product in the Ethylene Plants or Oil Refining processes. But the demand of Propylene is much higher as compared to the produce that is available in the above sources. Therefore Propane Dehydrogenation like methods are very important these days.

We Positive Metering Pumps India Pvt Ltd have expertise in manufacturing Skid Mounted Chemical Dosing Systems - like the Phosphate Dosing System that is necessary for the Propane Dehydrogenation process.

Propane is typically sourced from natural gas processing plants. It can also be obtained as a by-product of crude oil refining.

Propane is usually stored and transported in a liquid state under pressure, as it becomes liquid at relatively low pressures and ambient temperatures. This makes it easier and more cost-effective to handle and transport compared to storing it as a gas. However, during the dehydrogenation process in the PDH unit, propane is typically vaporized and fed into the reactor as a gas for conversion to propylene.

Phosphate dosing is often required in the process of dehydrogenation of propane to help mitigate catalyst deactivation. Phosphates can act as catalyst promoters or stabilizers, enhancing catalyst activity and selectivity by preventing coke formation and deactivation. They also help in controlling side reactions and improving the overall efficiency of the dehydrogenation process.

Phosphate is typically dosed into the feedstock or introduced into the reactor along with the feedstock during the dehydrogenation process. This allows for thorough mixing and interaction with the catalyst to provide the desired catalytic effects, such as stabilization and inhibition of coke formation. The exact dosing location may vary depending on the specific reactor design and process conditions.

Polypropylene production units are often integrated with propane dehydrogenation (PDH) units to utilize the propylene generated as a feedstock for polypropylene production.
