Liquid analysis in LNG trains
Complete solution out of one hand
In gas liquefaction plants, many parameters must be monitored to ensure the safety of the plant and the employees. The different process areas place different demand on the liquid analysis. This demanding area requires the highest level of process expertise and know-how.
Benefits and results
Complete solution from one source, which greatly simplifies operation
Plant operators benefit from state-of-the-art sensor and analysis technology like Memosens technology
Endress+Hauser is a solution partner with comprehensive know-how even for such complex applications
Customer challenge
In order to transport gas efficiently over long distances, the LNG liquefaction of natural gas is a common process. However, since natural gas is very fragile and highly flammable, safety precautions must be taken to protect the surroundings and the environment. Different limit values must therefore be complied with during the various process steps in a gas liquefaction plant. Due to the complexity of the plant, numerous measuring points must be installed and maintained.
Our solution
One part of the process is sulfur recovery. In the Sulfur Recovery Unit (SRU), the pH values in the waste heat boilers must be monitored in order to act immediately in case of events that can be recognized by the change in the pH value. This is done with a sampling system due to the pressure. The pH value is also an important parameter in the area of large boilers. Carbonite solution is used in the cleaning process. To treat the solution, the conductivity is monitored in the scrubber system.
