Boosting hydrogen production and sustainability 2020

HPCL Visakh case study

TechnipFMC was awarded a contract by the state-owned Hindustan Petroleum Corporation Ltd. for a grassroot Hydrogen Generation Unit (HGU). The project is part of the brownfield expansion for HPCL’s Visakh Refinery Modernization Project located in India. The contract covers project management, technology licensing, preparation of basic design and engineering package, as well as detailed engineering, procurement, construction, commissioning and performance guarantee test run on an LEPCC* basis.

Maximizing energy efficiency, minimizing CO2 emissions.

TechnipFMC provides a new Hydrogen Generation Unit (HGU) with its advanced technology for one of Hindustan Petroleum Corporation Limited’s (HPCL) refineries. The new world-scale Hydrogen Generation Unit is part of HPCL’s Visakh Refinery Modernization Project (VRMP), a strategic project for the government of India to meet growing consumer demand and new environmental requirements for fuel quality by raising the refinery capacity from 8.33 to 15 MMTPA**.

The selection of HGU process technology and configuration was driven by environmental and economic considerations to minimize CO2 emissions and reduce operating costs. The detailed execution plan addressed safety and logistical challenges inside an operational refinery to prevent incidents and shutdowns. With more than 1,500 people on site, work and equipment usage must be coordinated at all times.

HPCL Visakh


A unique technology combining several referenced and proprietary technologies.

TechnipFMC’ involvement in the project includes providing licensing, a basic design engineering package, engineering, procurement, construction and commissioning support. The hydrogen generation package is comprised of two grassroot HGU’s each with a design capacity of 113 KTPA, and a Hydrogen Recovery Unit (HRU) of 36 KTPA.

The HGU uses TechnipFMC’ Parallel Reformer (TPR©) and Process Gas Boiler, our proprietary technology for steam reforming. This marks the first hydrogen plant to undergo a grassroots installation of a TPR© to recover heat from the reformer effluent for producing hydrogen, reducing fuel consumption and CO2 emissions in combination with other advanced heat recovery methods.

Excess HP steam generated in the HGU is used by a condensing steam turbine generator to power the HRU, making the facility self-sufficient in steam and power during normal operation.

Sulphur content of the feed is reduced in an integrated pre-desulphurization section before being sent as sweet naphtha to feed the main HGU.
