Corinne Gas Plant - Executive Summary |
|
Corinne Gas Plant is located in a Rural Area of Clay County, Mississippi and is monitored on a routine daily basis of every 2 to 3 hours by a company pumper. The plant processes natural gas through a mechanical separation vessel (plant) reducing the BTU of the gas to meet gas pipeline requirements. The gas stream enters a compressor at approximately 45 PSIG and exits at 550 PSIG into the plant. The gas pressure is reduced to an exit pressure of 350 PSIG, the pressure reduction "stripping" the gas stream of liquid hydrocarbons (LNG) which is piped to a steel storage tank with a containment pressure of 170-175 PSIG. The system is equipped with High/Low check mechanisms and a relief valve on the tank to prevent overpressurization. Fail safe mechanisms, guages, etc. are checked on a daily basis to determine proper function, adjustment, repair, or replacement. Worst case release scenario would be a storage tank rupture, which could result in a exposure area of a 0.4 mile radius. Altermati ve release scenario would be overpressureization of the storage tank causing relief valve to open until shut down mechanisms are activated. This could result in a exposure are of a 0.1 mile radius. Five year accident history-None. Emergency Response is based on a one man operation. The pumper will respond to any accidental release by manual shut down of the system and alerting the proper agency based on the release scenario requirements. The operator anticipates a reduction in chemical inventory to minimize any accidental release exposure. Operator assumed operations of the Corinne Gas Plant on 2-27-99. |
