Palayesh Parsian Sepehr Gas Refinery was established in 2010 with the objective of extracting ethane and natural gas liquids from rich gas produced by the Tabnak, Homa, Shanol, and Varavi fields. Following a strategic restructuring and investment by a major private energy consortium in 2014, project execution accelerated significantly.

The project comprises two main operational sites:

Mohr Site (Fars Province): Dedicated to methane separation and sweet gas production.
Assaluyeh Site (Pars Special Economic Zone): Focused on the final fractionation of ethane, propane, butane, and gas condensate.
Construction began in 2015 and—despite logistical complexities and challenges posed by the COVID-19 pandemic—the facility successfully entered full operation in 2021. This project is regarded as a strategic milestone in the region’s energy sector, playing a pivotal role in supplying feedstock to petrochemical complexes and increasing exports of high-quality hydrocarbon products.

Today, utilizing advanced cryogenic technology and a highly skilled workforce, Parsian Sepehr Gas Refining Company is recognized as a leader in the gas refining sector, committed to sustainable development and the optimization of the gas value chain
