TransCanada conserves energy through increased efficiency
TransCanada Pipelines is implementing a number of measures to conserve the amount of gas required for pipeline operation. These measures include (1) introduction of onsite control computers to ensure that engines in the largest of the company's 48 compressor stations are operated with overall peak efficiency, (2) regular performance analysis of the compression equipment to ensure that each compressor unit is operating at peak performance, (3) introduction of second-generation jet-turbine engines at key compressor stations in the pipeline system, (4) waste-heat recovery from the compressor units to improve overall efficiency, (5) blowdown elimination of compressor blow-offs or venting during short-duration compressor shutdowns, (6) yard-piping modifications, (7) gas transfers using portable compressors, and (8) pipeline re-rating and the related sandblasting of the pipeline to reduce friction and allow operation at higher pressures to reduce the required compressor power and thus conserve fuel. These and other related activities contributed to delivering more than 1 trillion ft/sup 3/ of gas to Canadian and U.S. customers in 1975 with optimum efficiency and economy.
