Abstract

Natural gas (NG), recognized as one of the cleanest hydrocarbons, is increasingly becoming a major component of the global energy scenario. The consumption of NG is projected to increase by 50% or more by 2035 (Eveloy, Rodgers & Popli, 2014). In addition, the annual global demand for natural gas is expected to increase by 2.4% per year (IEA, 2015). This coupled with the fact that Canada is the world’s fifth largest producer of natural gas provides an incredible opportunity for Canada-wide transition to natural gas (NEB, 2015). Natural gas is positioned to play an integral role in the transition to a low carbon economy. However, part of this transition will require that existing and new natural gas processing facilities integrate innovative approaches to reduce life-cycle GHG emissions. Currently, 50% of the total cost associated with natural gas processing operations can be attributed to energy consumption (Energy Recovery Inc., 2014). In many cases, higher efficiency can be attained by harnessing energy that is already available in a processing facility usually in the form of waste heat streams (Energy Recovery Inc., 2014). As part of our study, we examined the application of heat recovery mechanisms in a natural gas processing facility to capture wasted heat to be converted into useful energy. Part of our analysis focused on analyzing both the technical and financial feasibility of implementing heat capture in various functional areas of a 100 MMSCFD natural gas processing facility. Through our analysis, on site cogeneration and the integration of compact heat exchangers emerged as the most feasible options for enhancing the overall efficiency of a natural gas processing facility. Other functional areas offer opportunities for further heat recovery. However, given the technical and financial limitations, these options are not currently deployable.
