HPCL-Mittal Energy (HMEL) has said that it has been granted three Indian patents, of which two introduce the world’s first design for crude pipeline pigs that enable simultaneous transportation of naphtha in a crude pipeline.

This breakthrough underscores HMEL’s position at the forefront of developing cutting-edge, globally pioneering technologies, the company, a joint venture between Hindustan Petroleum Corporation (HPCL) and Mittal Energy Investment, said.

Prabh Das, MD & CEO of HMEL, said, “Securing these patents is a testament to the ingenuity, passion, and technical excellence of the HMEL team. We remain committed to pushing the boundaries of innovation to enhance operational efficiency, safety, and environmental sustainability in the energy sector.”

The Patents granted include Innovative industrial pipeline cleaning pigs — engineered to allow simultaneous transportation of two distinct hydrocarbons within a single pipeline.

These are the first patented designs of their kind globally, setting a new benchmark in reliability and performance for crude oil logistics, HMEL noted.

The third patent is for a pioneering apparatus that generates green oxy-hydrogen gas, developed to support process improvements within refinery operations. This innovation contributes meaningfully to HMEL’s strategic focus on clean, sustainable technologies for the future, it added.

R&D and innovation are foundational to HMEL’s sustainability-driven growth strategy. With over 44 patents filed and 9 granted to date — achieving an industry-leading implementation rate of over 90 per cent — HMEL continues to lead Indian oil majors in the real-world application of patented technologies.
