SINGAPORE (CNI)--Thailand’s National Petrochemical Co (NPC) will shut its propane dehydrogenation (PDH) unit from Sunday (15 August) until 26 September for a maintenance turnaround, reducing its propylene output, the company said on Friday.

The company's PDH plant produces 100 000 tonne/year of propylene. NPC has an optimal 170 000 tonne/year propylene output, with the remainder coming from its 438 000 tonne/year cracker, an official told CNI. However, he noted that the cracker usually produces only 30 000 tonne/year of propylene.

He said the cracker’s propylene output is maximised through the use of liquefied petroleum gas (LPG) as feedstock, while it also uses ethane feedstock. The cracker will continue operations during the PDH shutdown.

The official said NPC had already arranged a product supply plan and informed its customers of the turnaround. Its major propylene consumers are HMC Polymers (HMC) and Thai Polypropylene (Thai PP).

NPC’s facilities are located in the Mab Ta Phut industrial zone in Rayong province.
