Re-powering Study for the Northport and Port Jefferson Power Stations Appendix II Northport System Descriptions Two (2) x 100% air compressors of the air-cooled (or water-cooled), lubricated, and rotary screw type. Each compressor is equipped with an inlet air filter silencer, air/oil separator vessel, air/water separator, aftercoolers, and controls. One (1) x 100% service air receiver is provided. The receiver provides surge capacity for the Service Air and Instrument Air Systems. It is constructed to ASME Code requirements and is designed for safe shutdown of the facility. The piping and control system will be arranged to prevent loss of pressure to the instrument air system on a service air system failure by a pressure control valve. The pressure control valve isolate the service air header on low instrument air pressure signal from the instrument air header and diverts air to the instrument air system. One, 100% duplex air drying train for the instrument air system. The train consists of a prefilter, air dryers, and after filter stations. The prefilter removes the bulk liquid water and particles (5 microns or smaller). After the air passes through the dryer, the after filter removes any particles from the dryer desiccant (3 microns or smaller). The air dryer is of the dual tower heatless regenerative desiccant type. The system automatically controls the regeneration cycle of the dryers as required. Each air dryer tower is 100% unit capacity such that one tower can supply full unit demand while the other is being regenerated. Each dryer and dryer tower will be equipped with remote operated isolation valves. One instrument air receiver is provided downstream of the dryers to provide surge capacity for the Instrument Air System. From the air filtration and drying units, instrument air is provided to the various instrument air users throughout the plant. 1.12 Plant Makeup Water Treatment Refer to PID 9-21A and 9-21B in Appendix III. For Northport, raw water (city water) is used for service water, fire protection, and demineralized water system makeup. Raw water is ultimately used in the steam cycle make up after being treated appropriately. Untreated water is stored in the raw water tank. The lower portion of the tank is dedicated for the fire protection system and water for the other systems in the upper portion. Raw water is drawn from a nozzle above the fire water storage high level. The upper portion of the tank has sufficient storage to meet raw water demand for a safe shutdown of the plant in the event of a loss of off-site water supply. Two 100% capacity service/raw water pumps are provided. The service water system provides a feed to the water treatment cycle, and to miscellaneous plant washdown services. Refer to PID-09-21A in Appendix III. For Northport, two 100% demineralizer feed pumps direct water from the service water tank to a reverse osmosis/EDI demineralizer system. Pumps are started and stopped by the operator from the control room using the distributed control system (DCS). Demineralized water is directed via demineralizer outlet pumps to the demineralized water storage tank. Two 100% demineralized water forwarding pumps draw suction from the tank to distribute water to the condenser for steam cycle make-up, combustion turbine March 30, 2009 154

All liquid wastes produced within Northport are collected in their designated sumps and pumped to the existing wastewater treatment system. Each sump will have two 100 percent capacity sump pumps controlled by float-switch actuated mechanical alternator to equalize the wear on pumps. Each sump pump will be installed according to the manufacturer’s recommendations for the clearance between the pump casing and the floor of the sump. Each sump float-switch actuated mechanical alternator will provide protection for its pumps by stopping the operating pump at a predetermined low level in the sump. The pump alternator will also have a high level switch to start the selected pumps and a high-high level switch to start the standby pump and alarm. Each sump has its own set of controls and manual valves. Steam turbine area wastewater is collected in the condensate sump. One of two 100 percent condensate sump pumps route condensate sump water to the oil/water separator. Oily runoff and drainage from the power block and surrounding areas is collected in the oil/water separator. Water separated from the oil is routed to the wastewater collection sump by one of two 100 percent oil/water separator sump pumps. HRSG blowoff tank discharge and HRSG drain water is collected in the HRSG sumps. Each HRSG has a dedicated sump. One of two 100 percent HRSG sump pumps route HRSG sump water to the circulating water system for discharge. Wastewater from the oil/water separator, the water treatment building, and the demineralizer system is collected in the wastewater collection sump. One of two 100 percent wastewater collection sump pumps route wastewater to the existing wastewater treatment system. Sanitary waste is collected in the sanitary lift station. One of two 100 percent sanitary lift station pumps route sanitary waste to the septic system. 1.14 CT Auxiliary Services Refer to P&ID 39-02A in Appendix III. CT auxiliary services consist of interconnecting piping and tubing associated with the combustion turbine/generator vendor supplied equipments skids. The equipment skids supplied are: 1. CO2 Fire Protection Skid 2. Exhaust Duct Pressure Switch Package Skid 3. Performance Monitoring package Skid 4. Evaporative Cooler Skid 5. Water Wash Skid 6. Air Processing Unit Skid 7. Water Wash Drain Tank 8. Accessory Module (integral with combustion turbine skid) March 30, 2009 155
