The Urgent Need to Curb Methane Emissions
The energy sector’s decarbonization progress will hinge upon its ability to reduce greenhouse gas (GHG) emissions. Among these gases, perhaps none poses a more urgent challenge than methane. Approximately 28-34 times more potent over 20 years than CO2, methane is estimated to have contributed 20% of the global temperature increase since the Industrial Revolution, according to the Environmental Protection Agency (EPA). Another environmental authority, the International Energy Agency (IEA), estimates that the oil and gas sector produces 40% of the world’s methane emissions each year.
Fugitive emissions, or unintentional emissions caused by leaks or defective seals, account for as much as 20% of all global methane emissions, or 5% of global GHG emissions. Because fugitive emissions are especially common in carbon capture, utilization and storage (CCUS) and natural gas operations, methane abatement is also critical to accelerating decarbonization and LNG as a bridge fuel.
Beyond these environmental and energy transition implications, methane also impacts a business’ bottom line. According to the EPA, methane leaks account for around 3% to 4% of total gas production; that translates to annual potential revenue losses of up to $30 billion for the oil and gas sector. The dual climate and business impact of methane emissions has accelerated abatement technologies, which have become increasingly cost-effective with time. As we enter the next phase of the energy transition, methane reduction has become a rapid, economically viable strategy for decarbonizing the oil and gas industry.

Our Approach to GHG Emissions Reduction
John Crane has been a leader in methane abatement for decades. Our advanced mechanical sealing technologies have prevented millions of tonnes of GHG and methane from being released into the atmosphere, and we’re continuing this legacy in the new energy era. We believe that the most effective route to curbing methane emissions lies in identifying the sources of emissions and providing cost-effective solutions that reduce or eliminate emissions while maximizing efficiency. We are committed to helping the oil and gas sector significantly reduce its emissions — including those from methane, sulfur oxides and nitrogen oxides — by leveraging this proven approach.
To support our customers’ emissions reduction goals, John Crane offers a range of emission management solutions, including products such as dry gas seal and wet-to-dry gas retrofit solutions. We pair these solutions with the same pioneering spirit and innovation that led to our invention of the first mechanical seal more than a century ago.
Emissions Detection and Quantification Technologies
There is no shortage of methane abatement solutions in today’s market. However, few address fugitive emissions, which remain a critical barrier to the oil and gas industry’s net zero progress. John Crane’s solutions enable process operators to detect, quantify and reduce methane and other greenhouse gas emissions — including often-undetected fugitive emissions. By doing so, we help energy companies meet their methane reduction goals and satisfy the latest environmental standards without sacrificing reliability or cost.
Repair and Mitigation Technologies
Proven Wet to Dry Gas Seal Retrofits
Over the last 10 years, John Crane’s wet-to-dry upgrades have helped customers reduce approximately 278,000 tonnes of CO2 equivalent emissions per year. By switching to our Wet-to-Gas (W2G) seals, customers around the globe are minimizing methane leaks and emissions while boosting the reliability of their compressors. These retrofit solutions improve a plant's efficiency and reduce its environmental footprint while significantly cutting emissions.
At John Crane, we thrive on service excellence. We help our customers through every step of the retrofit process, from conceptual studies to implementation, ensuring their transition to dry gas seals maximizes efficiency and reliability. We also specialize in optimizing pump and compressor systems, making us the trusted choice for boosting the performance and sustainability of this mission-critical equipment.

Preventing and Eliminating Emissions With Seal Gas Recovery
Centrifugal compressors equipped with tandem Dry Gas Seals (DGS) can utilize Seal Gas Recovery (SGR) to reduce emissions when there is access to high-pressure motive fluid. SGR becomes even more cost-effective when processing valuable gas. John Crane can design a customized SGR arrangement for setups involving multiple compressor trains.

Decreasing Emissions by 98% in an Oman Production Plant
A prominent exploration and production firm in Oman partnered with John Crane to reduce emissions and enhance operational efficiency. By replacing conventional oil seals with advanced Type 28 dry gas seals, we helped our customer decrease its CO2 emissions by 98% and lower gas consumption by approximately 2% in the gas turbine — all while achieving higher-quality gas with lower oil removal costs.
Beyond emissions reductions, our wet-to-dry gas retrofit enhanced reliability, improved mean time between failures (MTBR) and reduced expenses for both maintenance and energy. Our customer further also benefited from educational sessions with its local operators, which equipped them to maximize the value of their dry gas seal technology.
