This project retrofited the digester gas engines at Plant No. 1 and Plant No.2. The emissions control work included the installation of catalytic oxidizer/selective catalytic reduction systems and digester gas cleaning systems at Plant No. 1 and Plant No.2. Under this contract, Shimmick installed a steam convertor at Plant No.2, installed a HVAC system at Plant 2, replaced the Plant No.1, and installed Plant No. 2 CenGen roofs. Additional work included absorption chillers, intake fans, and piping modifications. Shimmick self-performed the electrical, mechanical, civil, structural-concrete, structural-steel, insulation and commissioning.
Facility operations could not be impacted and continuous operations of the eight engines were required to be maintained to allow for the uninterrupted generator operation for plant electricity. Therefore, it was necessary for complex sequencing and coordination with the Owner which Shimmick successfully accomplish.
Facility remained operational during the entire construction and project was completed on time.
