Energy Globe Award

With more than 178 participating countries and over 2000 project submissions annually the Energy Globe Award is today's most prestigious environmental prize worldwide. It distinguishes projects regionally, nationally and globally that conserve resources such as energy or utilize renewable or emission-free sources. Award ceremonies are held all over the world. Prominent personalities as well as Energy Globe Ambassadors in 90 countries support the mission of Energy Globe. The activities of Energy Globe attract worldwide media attention - international TV stations report each year with approximately 1,000 hours of broadcasting time. The aim of the Energy Globe is to raise global attention on sustainable, everywhere applicable environmental solutions and to motivate people to also become active in this area.

National ENERGY GLOBE Award Saudi Arabia 2017

Submitted by: Saudi Aramco/Yanbu NGL Fractioantion Plant
Flare Gas Recovery Project

A flare gas recovery project recovers the ethane tank boil off and compresses it instead of flaring it into the atmosphere, reducing the annual CO2 emissions by 30,000 tons.

Initial situation
Yanbu NGL Fractionation Plant (YNGL) uses an ethane storage system that stores ethane at -126°F in order to provide its petrochemical customers with ethane in case of any emergency that prevents YNGL from producing ethane for a certain period. A flaring system is connected to the ethane tank to flare the accumulated ethane vapor in the tank dome, in average 800 Million Standard Cubic Feet (MSCF) daily. Since the plant’s commissioning in 1982, 800 MSCF of ethane are flared on a daily basis that impact the environment. This is considered as energy waste since ethane has around 1750 British Thermal Units (BTU). Recovering this waste is important as Saudi Aramco is transforming to lead the energy business and therefore works hard to have the most efficient and optimized means of utilizing its energy resources.

This flare gas recovery project will be completed in 2022 and will recover the ethane tank boil off and compress it to the ethane customers’ header instead of flaring the ethane into the atmosphere. Earlier, YNGL employed an Innovation Challenge Program in order to steer the innovative thinking of its talents and challenge the cost and execution time of the approved flare gas recovery capital project. The innovation platform has resulted in identifying a new low-cost recovery scheme for ethane tank boil off which led to eliminate the flare from the tank. This scheme utilizes a variable speed blower to recover the boil off ethane by increasing its pressure. Then, the recovered ethane is proceeded as fuel gas to a boiler in the utilities area. The new scheme eliminated the flared ethane by 292 MSCF per year and reduced the annual CO2 emissions by 30,000 tons.

The project is resolving an issue that was haunting the company since the plant's commissioning in 1982, namely the negative impact on the environment as well as energy and resource waste. Equipment already available in the market was used to resolve the waste issue and the negative environmental impact. Since a compressor and cooling medium were too expensive and therefore not approved by the management, another idea was needed. The innovation platform then came up with this idea of the low-cost recovery scheme.

We are an enthusiastic supporter of the Energy Globe Awards and its aim to strengthen society’s awareness of the necessity for ecological change, by honouring outstanding best practice projects in environmental sustainability from all parts of the world. ADVANTAGE AUSTRIA is the official Trade Promotion Organisation (TPO) of the Republic of Austria and as a country we are proud of our success in green technologies. Our support of the Energy Globe Awards continues this tradition.
