Solutions in Action: Valves, Actuators and Regulators for the Entire LNG Value Chain
Inlet Feed and Separation Solutions
Inlet receiving facilities knock out liquids in the feed gas, reduce pressure from the gas pipeline, and throttle gas flow into the downstream processing units. Stable and reliable operation is crucial for profitable LNG production, as unexpected maintenance or failures can result in significant penalties.
Our value:
- Maximize condensate recovery to prevent the introduction of liquids in the downstream treatment process
- Improve energy use
- Ensure uptime with 100% operational redundancy
- Increase throughput
Fisher™ Pressure Letdown Valve
Provide the proper rate of flow into the facility.
Fisher™ Slug Catcher Inlet Valve
Provide the final pressure cut before the fluid enters the slug catcher and jump starts the separation
KTM™ Feed Gas Isolation Valves
Isolate feed gas reliably with fully engineered, automated valve solutions.
Acid Gas Removal & Dehydration Solutions
The acid gas removal unit reduces the concentration of hydrogen sulfide (H2S) and carbon dioxide (CO2) present in the feed gas through amine treatment or a sweetening process. The dehydration unit then removes moisture from the sweet gas to avoid dropout and hydrate formation under cryogenic conditions downstream.
Our value:
- Utilize advanced severe service valve technology to optimize challenging applications in the LNG value chain, handling abrasive adsorbents, corrosive gases, thermal transients, and frequent cycling.
- Remove all contaminants to contractually specified levels
- Eliminate hydrate formation from H2S, CO2 and H2O in cold sections of the process to avoid damaging cryogenic units
- Maintain emissions below permit limits
- Improve the unit's ability to dry the natural gas feedstock by providing critical sequencing of dehydration beds
Fisher™ Rich Amine Letdown Valve
Regulate the level of rich amine solution that accumulates in the bottom of the contactor vessel.
Vanessa™ Triple Offset Valves for Dehydration or Molecular Sieve
Outperform traditional isolation valves with increased durability, reliability, and lower ownership cost.
AEV Dehydration or Molecular Sieve Switching Valves
Revolutionize the way you think about ball valves in the isolation of your severe service processes.
Sulfur Recovery Solutions
An imbalance of combustion air in sulfur recovery units can lead to an excess of hydrogen sulfide or sulfur dioxide in the tail gas, potentially causing a shutdown of the entire LNG facility. Corrosion presents an ongoing challenge in this context. Furthermore, overall throughput may suffer if the sulfur that is being removed cannot be fully processed.
Our value:
- Ensure consistent and safe combustion control while minimizing the impact of corrosion
- Avoid limited throughput due to sulfur content
Fisher™ Acid Gas from Amine Valve
Effectively handle highly-sulfuric processes, like bringing acid gas to the thermal reactor, with durable, NACE-compliant materials.

Vanessa™ Triple Offset Valves for Sulfur Recovery Unit
On/off or bypass valve solutions featuring a thermal jacket, bearing flushing, and dedicated material selection to protect against thermal loss, medium solidification, and corrosion.
Fractionation Solutions
The fractionation process separates a raw stream of mixed natural gas liquids (NGLs) typically consisting of ethane, propane and butane into primary hydrocarbon components. It occurs in stages by boiling off hydrocarbons from the mixed stream and recovering the pure product stream via an overhead condenser, based on regional demand and economics.
Our value:
- Increase NGL recovery
- Meet product purity specifications and yields
- Minimize loss of valuable gas components
Fisher™ Booster Pump Recycle Valve
Recycle flow through the ethane booster pump when needed to prevent cavitation damage.
Fisher™ Expander Bypass Valve
Enable an efficient startup and shutdown of the turboexpander and protect it in the event of a system upset.
Vanessa™ Triple Offset Valves
Isolate inlet and outlet lines of the fractionation units with fully engineered, automated isolation solutions.
Main Cryogenic Heat Exchanger Solutions
The main cryogenic heat exchanger (MCHE) is the heart of the liquefaction facility. It liquefies natural gas then subcools it. The MCHE is composed of a large number of spiral wound tube bundles. When the feed gas exits the top of the MCHE, it has been turned into liquid as the temperature has been reduced to approximately -146°C (-231°F).
Our value:
- Maintain optimum refrigerant flow circulation
- Reduce energy consumption when feed is restricted
- Product more LNG with high-precision controlling elements that enable optimal controller
Fisher™ Joule-Thomson Valve
Utilize pressure drop to achieve cooling of liquids, gases, or multiphase fluids.

Fisher™ LNG Temperature Valve
Control the temperature of LNG coming out of the main heat exchanger.
Compression Train Solutions
Centrifugal compressors are essential for the gas liquefaction process, providing multi-stage compression of refrigerants to turn natural gas into its liquid state for storage and transport and supporting uninterrupted LNG production.
Our value:
- Achieve maximum compressor efficiency and high throughput
- Protect critical compressors from surges, failures and shutdowns
- Avoid pollutants and dangerous emissions of volatile organic compounds

LNG Storage, Jetty Loading & Boil-Off Gas Solutions
Typically, two or more above-ground tanks are used to receive store LNG. Boil-off gas (BOG) produced in the tanks and LNG lines by heat transfer is compressed and liquefied in a recondenser to avoid flaring or venting and minimize environmental impact.
Our value:
- Recover boil-off gas
- Detect gas leaks
- Reduce the total installed cost of loading arms
- Minimize valuable product loss
Vanessa™ Triple Offset Valves Cryogenic Configuration
Combine best reduction in footprint and total cost of ownership with superior performances in cryogenic conditions.

Protect the compressor from damaging surge events with quick and accurate valve response to immediately recycle the discharge flow.
Fisher™ LNG Injector
Inject LNG into the gas to cool it.
Unloading, Storage & Regasification Solutions
An LNG receiving terminal is where vessels are unloaded and where large insulated holding tanks are used to keep the LNG at atmospheric temperature. A vaporization system is used to turn the LNG back into a gaseous state before it is distributed through a natural gas pipeline system.
Our value:
- Maintain stable regasification operations under all conditions
- Minimize energy consumption and emissions
- Improve personnel and equipment safety
- Efficiently manage customer delivery expectations
- Reduce the total cost of unloading arms

Frequently Asked Questions About LNG Valves
LNG valves are essential for maintaining safety in LNG plants because liquefied natural gas, whether methane, ethane, propane, or butane, is highly flammable. Properly functioning valves are crucial for preventing leaks, controlling pressure, and managing emergency situations, thus mitigating critical safety risks.
Since the introduction of LNG plants in the 1930s, LNG valves have evolved to handle significantly larger liquefaction trains. Valve manufacturers now focus on producing larger-sized valves that can accommodate high pressures and ensure safe pressure control, isolation, and emergency operations in response to the growing global demand for LNG.
One of the key challenges for LNG valve manufacturers is developing valves that can handle large sizes and high pressures. These valves are essential for process control, isolation, emergency operations, and protecting major equipment in LNG plants, where safety is a critical concern. Emerson is highly experienced with producing valves that support the entire LNG value chain – including, liquefaction facilities, carriers, and regasification terminals.
Valves play an essential role in LNG infrastructure by facilitating equipment isolation for maintenance, process on/off, regulation/control, and emergency shutdowns. Proper valve technology selection and configuration is critical to ensure safe, sustainable and profitable operations. Emerson offers a vast portfolio of manual and actuated valves for LNG, covering the entire production chain and distribution.
LNG valves in on/off configurations can be actuated using pneumatic, electric, or hydraulic systems. These actuation options allow the valves to be automatically controlled, ensuring that LNG processes are efficiently managed and that the valves can respond quickly to changes in operating conditions.
