Nitrogen Distribution System

To describe the procedure for validation of the nitrogen distribution system to be installed and operated per spedhcation 

The technical services manager is responsible for following the procedure. The quality assurance manager is responsible for SOP compliance. 

Eor sampling procedure see SOP No. Val. 600.100, step 5.1, of the guideline for an oil-free compressed air system. 

Samples for analysis should be taken from each critical supply point, and meet the official monographic requirement. 

Results should be in compliance with pharmacopial monograph

The nitrogen distribution system must consistently deliver pressurized nitrogen to the use points at the design pressure specified. 

Utility stations in a nitrogen distribution system must be clearly identified. Special connectors and hoses which are not common to any other system should be used.

In order to provide residual disinfectant in the distribution system, chloram-ination is applied to the treated water. If three moles of HOCl have been added per mole of ammonia, calculate the moles of nitrogen gas produced. In order to provide residual disinfectant in the distribution system, chloram-ination is applied to the treated water. If three moles of HOCl have been added per mole of ammonia, calculate the moles of trichloramine produced. In order to provide residual disinfectant in the distribution system, chloram-ination is applied to the treated water. If three moles of HOCl have been added per mole of ammonia, calculate the moles of laughing gas produced. Show the half reaction that will exhibit the property of organic chloram-ides as disinfectants. 

Make specific allowances for distribution systems within the process area for the various utilities cooling water, high/low pressure steam/condensate, service water/air, nitrogen, instrument air, vent collection systems, etc. Lengths and sizes must be determined based on arrangement and flows. Allow at least 30 ft. of pipe from distribution system to each individual user.
