“…The use of absorption cooling in power plants , chemical processing plants , and petroleum refineries has been proposed in the past but has only been considered recently in the NG industry . Thermal energy storage in the form of ice or chilled water in conjunction with absorption refrigeration has also been investigated in an oil field Oman but found to be economically unviable, given the need for continuous GT inlet air cooling in summer. In the present study, an absorption refrigeration‐based CCP system is evaluated in a Gulf NG production facility to simultaneously provide additional electric power through GT compressor inlet air cooling and to enhance process gas cooling capacity.…”

SUMMARY Most natural gas (NG) producers in the Persian Gulf face increasing challenges in meeting their domestic gas demands and therefore seek to reduce their NG consumption. Concurrently, the on‐site power generation and cooling capacities of local NG processing facilities are constrained by extreme climatic conditions. A combined cooling and power scheme based on gas turbine (GT) waste heat‐powered absorption refrigeration is techno‐economically assessed to reduce the NG consumption of a major gas processing plant in the Persian Gulf. The scheme utilizes double‐effect water‐lithium bromide absorption refrigeration activated by steam generated from GT exhaust gas waste heat to provide both GT compressor inlet air and process gas cooling. Based on a thermodynamic analysis, recovery of 150 MW of GT waste heat is found to enhance the plant cooling capacity by 195 MW, thereby permitting elimination of a 32.6 MW GT and existing cooling equipment. On‐site power generation is enhanced by 196 GWh annually through GT compressor inlet air cooling, with energy efficiency (i.e., 64%) improved by 35% using cogeneration relative to the existing power generation plant. The overall net annual operating expenditure savings contributed by the combined cooling and power system are of $US13 million to 34 million based on present and projected local utility prices, with an economic payback period estimated at 2 to 5 years. These savings translate to approximately 94 to 241 MMSCM of NG per year, highlighting the potential of absorption refrigeration to both enhance the power generation and cooling capacity of hydrocarbon processing plants exposed to harsh environmental conditions and to realize substantial primary energy savings.

“…The chillers charge the TES during off‐peak hours and the TES performs TIC during peak hours with minimal parasitic load. In order to be economical, this operational strategy generally requires that electricity prices are higher during peak hours than off‐peak hours . Although absorption chillers can also be coupled with TES for TIC , nearly all TIC–TES systems use mechanical chillers as opposed to absorption chillers.…”

SUMMARYTurbine inlet cooling (TIC) is a common technology used to increase combustion turbine power output and efficiency. The use of mechanical or absorption chillers for TIC allows for more air cooling than evaporative methods and also imposes a significant parasitic load to the turbine. Thermal energy storage (TES) can be used to shift this load to off-peak hours. Use of thermal storage increases the flexibility of turbine power output, which benefits from the application of optimization tools. This paper explores the effect of combining TIC with TES to enhance the performance of a district cooling system that includes a gas turbine for power generation. The work illustrates how the system's performance can be enhanced using optimization. Application of multi-period optimization to the system that includes TES brings significant operational cost savings when compared with a system without thermal storage. It is also shown how TES provides demand-side energy management in the district cooling loop and supply-side management through the use of TIC. In addition to the optimization study, a thorough literature review is included that describes the current body of work on combining TIC with TES.

Experimental analysis is carried out on tube in tube type heat exchanger. The phase change material (PCM) is melted under the influence of hightemperature air as HTF. PCM density effect is presented with the temperature change in axial and radial positions. During charging, the lower elevation temperature curve's intersection with the higher elevation's temperature curves is identified. The earliest intersection is found at 20 minutes with 51 C. The late intersection is found at 62 minutes and 75 C. Natural convection jump phenomenon is also spotted. Each temperature curve in middle and outer radial positions is classified into three categories (before the jump, during the jump, and after the jump). Natural convection jumps are found in the range of 2.667 to 8.5 C/minute. The density effect and natural convection jump are found to be insignificant during discharging.
