About this file
This document is a Piping and Instrumentation Diagram (P&ID) for the Aqueous Ammonia System for the Glenarm Repowering Project, prepared by WorleyParsons for the City of Pasadena Water & Power Department. The diagram details the final configuration of the ammonia handling infrastructure, including an existing ammonia storage tank (B3) with 11,890 gallons capacity, two ammonia forwarding pumps (Pump A and Pump B), each with a capacity of 190 lb/hr, 1/2 HP motors, and a total dynamic head of 16 ft. The system includes multiple valves, flow indicators, pressure switches, and safety features such as excess flow limiting valves and double-contained buried piping with leak detection provisions.
The technical specifications indicate the ammonia system is designed to support the Selective Catalytic Reduction (SCR) systems of five natural gas-fired combustion turbines at the Glenarm Power Plant. Key technical requirements include meeting ECM requirements for transfer pumps, replacing existing instruments on the storage tank, and specific piping and valve configurations. The diagram provides comprehensive details on system connections, flow rates, pressures, and temperatures, with notes specifying technical standards, numbering procedures, and installation guidelines. The document is marked as an "as-built" drawing, indicating it represents the final installed configuration of the ammonia handling system.
