Wyeth BioPharma Central Energy Plant Expansion
Wyeth is a major pharmaceutical facility in Andover, Massachusetts. The facility consists of five buildings, all with specialized manufacturing suites. A central energy plant provides electricity, chilled water and high pressure and low pressure steam to the various buildings.
Waldron Engineering's current project at Wyeth is in support of a central energy plant expansion and is broken down into three phases. Each phase requires a multidisciplinary approach, which includes civil/structural, electrical, mechanical and instrumentation and controls engineering. Phase I was completed in August, 2001, consisted of system engineering and installation of a 1150 ton electric centrifugal chiller, a single cell 2800 gallon per minute (GPM) cooling tower, 4000 GPM variable speed chilled water pump and a 2000 KW Caterpiller D3516 emergency generator with accompanying switchgear and controls.
Phase II was completed in January, 2002, and consisted of the engineering and installation of a 1150 ton double effect steam absorption chiller, a second single cell cooling tower, a 3000 gallon per minute primary cooling water pump, a 2300 gallon per minute primary chilled water pump, a second variable speed secondary chilled water pump, and a second 2000 KW emergency generator.
Phase II is currently underway and scheduled for completion in summer of 2003, it consists of doubling the capacity of the existing cogeneration system. The existing cogeneration system currently produces 5MW of prime power and 40,000 pounds per hour of 125 psi saturated steam.
Phase III of the project will add a dual fuel Solar Taurus 60 gas turbine/generator, a 40,000 pound per hour, natural gas fired waste water heat recovery boiler, emissions control and monitoring equipment and all associated power distribution and control systems.
