Underground gas containers Back

Product description

The control system ensures the safe and smooth operation of underground natural gas reservoirs. The following processes are controlled and monitored at the facility: dehydration and filtration of the gas, glycol regeneration, compressors, gas cooling, methanol injection, natural gas extraction and injection. The system is able to integrate auxilliary technology, such as a boiler house, fire pumps and security devices. The facility is controlled from a central control room. Operational diagnostics can be run locally via webserver. Documentation for underground storage is created using the COMOS tool, which enables developing the project of measurement and regulation equipment as well as the application software in one universal environment. Information from all the different parts of the project is stored in a central database and any change is automatically distributed throughout the whole collection of documents.
