PILOT L52316 Small Scale Waste Heat Recovery Study

THIS IS A PILOT PRODUCT. DO NOT PURCHASE.

Two important and current topics of interest for gas machinery operators are emissions and energy efficiency. Current climate change legislation is leaning towards reduced emissions and improvements in energy utilization efficiency, which has renewed the interest in Waste Heat Recovery (WHR) at pipeline stations. In the past, the focus of WHR has been on large-scale applications, with little attention paid to small-scale WHR systems.

Many of the concepts discussed in this report have been used in other applications or part of the concept has been implemented before, but not while using waste heat. Some of the other concepts are new ideas that have not been done and require a significant amount of development, before they can be implemented in the future. Out of the top ten concepts identified in this study, there are three main areas, which if developed further, have a high potential benefit to the station or could enable the use of many of the WHR concepts.
