Valves for Gas Processing & LNG
The main structural feature
of these valves is the
enclosed vapor chamber
which isolates the packing
from the the cryogenic
fluid, allowing the packing
to function properly.
SUB-ZERO TEMPERATURE VALVES
THE LADISH DIFFERENCE
Ladish Valves ability to manufacture specifically designed cryogenic valves and to convert standard valves to cryogenic service, all in-house, allows for a completely controlled quality process.
In addition, our custom designed bonnets and modified extended bonnets provide safe, dependable service to LNG receiving terminals and liquefaction facilities as well as processes using liquid nitrogen and hydrogen.
THE LADISH DIFFERENCE
DEPENDABLE PERFORMANCE AT SUB-ZERO TEMPERATURES
Ladish custom designed bonnets and modified extended bonnets provide safe, dependable service to LNG receiving terminals and liquefication facilities as well as processes using liquid nitrogen and hydrogen.
Choosing valves for cryogenic service can be complicated.
The production, transport and storage of liquefied gases such as oxygen, nitrogen and natural gas demand a thoughtful solution.
Gas Processing
Gas processing is a range of industrial processes designed to purify raw natural gas by removing common contaminants such as water, carbon dioxide and hydrogen sulfide. This is designed so that the plant can deliver pipeline-quality dry natural gas that can be used as fuel by residential, commercial and industrial consumers.
Separation
Raw natural gas is collected from wells and is processed to remove water & natural gas condensate
The condensate is generally transported to a refinery
Water is disposed of as wastewater
Processing
Raw natural gas travels through a pipeline to a gas processing plant where initial purification begins
Acid gases such as hydrogen sulfide and CO2 are removed through a processes called Amine Treating
Acid gases are routed to a sulfur recovery unit which converts hydrogen sulfide into sulfuric acid
Dehydration
The process in which water vapor is remoced from the gas
Using low temperature distillation, nitrogen is removed from the gas
Recovery
The processes used to recover natural gas liquids (NGL) using a fractionating column
LNG
Liquefied natural gas (LNG) is a natural gas that has been cooled to a liquid state for shipping and storage. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state in a natural gas pipeline.
Liquefaction
The process by which pollutants are removed from the natural gas
C02 is absorbed and removed from the natural gas so that ice doesn’t form
Hydrocarbons are removed by fractionation to then be liquefied
Transport
NGL is transported as a mixed product to local refineries and/or chemical plants for use in feedstocks
For lengthy travel or travel in which pipeline is inaccessible, natural gas is routed by ship as LNG and re-converted into gas by the end consumer
Storage
At import terminals, LNG is offloaded into cryogenic storage tanks before its returned to its gaseous state
Regasfication
LNG is reheated with a heat exchanger and converted back into gas using methods such as submerged combustion and open rack vaporizing
