Lng Overview

OVERVIEW

Driving the energy transition

Globally, the demand for liquid natural gas (LNG) is increasing    rapidly. As a crucial bridge fuel, LNG has the potential to reduce CO2 emissions while supporting large-scale hydrogen production.

Since 1991, when John Crane first provided a dry gas seal for this application, we have been at the forefront of the industry.

Today, many of the world’s largest LNG production sites are John Crane dry gas seal customers — and we’re continuing to innovate. We are investing heavily in next-generation solutions to enhance reliability across the LNG value chain, today and in the future.

To fully capitalise on LNG’s potential during the energy transition, rotating equipment must be designed to meet the complex dynamics of natural gas. LNG facilities operate around the clock, so maintaining uninterrupted performance is crucial to maximise output.

Any downtime can lead to substantial financial losses and increased gas costs for end users. Additionally, increasing capacity often necessitates larger turbomachinery equipment with unique requirements.

John Crane leverages decades of specialised LNG experience to deliver market-ready seal face technologies, filtration solutions, couplings and digital innovations that strengthen the value chain.

FREQUENTLY ASKED QUESTIONS

Common Questions

What is Liquid Natural Gas (LNG)?

Liquid Natural Gas (LNG) is a natural gas that has been cooled to approximately -161°C (-259°F) to
convert into a liquid state. This process reduces its volume by about 600 times, making it easier to
store and transport over long distances in specialised LNG carriers, including tankers and ships.
These vessels play a crucial role in the supply chain, ensuring safe and efficient delivery from
production facilities to key terminals and the global market. Additionally, specialised gas carriers
are designed to maintain LNG at cryogenic temperatures during transit.

LNG is a versatile energy source used for power generation, heating, and as a fuel for industrial
applications and transportation. It's also one of the cleanest natural gases, producing 40% less
carbon dioxide than coal and 30% less than oil. Industries such as shipping and heavy
manufacturing rely on it for cleaner and more efficient energy solutions.

What types of LNG equipment are used in gas processing and LNG facilities

Gas processing and LNG facilities rely on a wide range of LNG equipment, including compressors,
pumps, turbines, heat exchangers, storage systems and rotating equipment. These assets require
reliable sealing and power transmission technologies to help maintain operational efficiency,
safety and performance in demanding cryogenic environments.

What challenges do operators face in gas processing and LNG applications?

Gas processing and LNG facilities operate under extreme conditions, including cryogenic
temperatures, high pressures and continuous production demands. These environments require
engineered solutions that can help minimise leakage while protecting critical equipment and
supporting safe, reliable operations across the LNG lifecycle.

Why is equipment reliability important in LNG facilities?

Equipment reliability is critical because unplanned downtime can impact production, safety and
operating costs. By utilising proven LNG equipment technologies and reliability-focused solutions,
operators can improve uptime and maintain consistent performance throughout LNG operations.

How does John Crane support oil and gas LNG operations?

John Crane supports oil and gas LNG operators with advanced sealing technologies, couplings,
filtration systems and reliability-focused engineering expertise. These solutions are designed to
help improve equipment performance, reduce downtime, enhance safety and support efficient
operations across gas processing and LNG facilities.
