The nitrogen production system of an offshore oil field relies on the public gas system of the platform to continuously deliver clean nitrogen to the production process.In the process of nitrogen production,the nitrogen production system always consumes a large amount of public gas.This leads to frequent loading of the air compressor and increases the load of the public gas system,which is easy to cause the high temperature alarm shutdown of the air compressor outlet,affect the stability of the public gas system,and reduce the service life of the unit.A pneumatic valve is added in front of the membrane separation system.The newly added pneumatic valve is opened or closed according to the pressure of the nitrogen tank,so as to control the on-off of the public gas used for nitrogen production.This transformation and upgrading can effectively avoid the long-time loading and operation of the air compressor,reduce the consumptions of energy and public gas,and greatly improve the stability of the public gas system of the platform.
