Wyeth BioPharma
Wyeth BioPharma is a major biotechnology facility in Andover, Massachusetts consisting of five buildings, all with specialized manufacturing suites. A Central Energy Plant (CEP) provides operational electricity, emergency power, compressed air, chilled water as well as high pressure and low pressure steam to the various buildings.
Wyeth's Central Energy Plant expansion was engineered and constructed by Abington-Waldron, LLC (a company comprised of Waldron Construction, Waldron Engineering, and Abington Group) under an EPC contract. There were three phases to the contract. Each phase required a multidisciplinary approach, which included civil / structural, electrical, mechanical and instrumentation and controls.
Phase I - Engineering, procurement and installation of a 1,150 ton electric centrifugal water chiller, a single cell 2,800 gallon per minute cooling tower, a 4,000 gallon per minute variable speed secondary chilled water pump, modifications to the fuel unloading system, two 125 foot stacks, an auxiliary cogen cooling system and a 2,000 kW Caterpillar D3516 emergency generator with accompanying switchgear and controls.
Phase II - Engineering, procurement and installation of a 1,150 ton double effect steam absorption chiller, a second single cell cooling tower, a 3,000 gallon per minute primary cooling water pump, a 2,300 gallon per minute primary chilled water pump, a second variable speed secondary chilled water pump, and a second 2,000 kW emergency generator. Phase III - Engineering, procurement and installation consisted of doubling the capacity of the existing cogeneration system. The original cogeneration system produced 5 MW of prime power and 40,000 pounds per hour of 125 psi saturated steam. Phase III of the project included civil, structural and architectural modifications to the cogen building, an additional gas compressor as well as the addition of a dual fuel Solar Taurus 60 gas turbine generator, a 40,000 pound per hour natural gas fired waste heat recovery steam generator, SCONOx emissions control system, continuous emissions monitoring equipment and all associated power transformers and distribution and control systems.
