Energy and exergy analysis of a combined transcritical CO2 compression refrigeration and single effect H2O-LiBr vapour absorption system
A refrigeration system is conceived and analysed wherein high grade waste heat from the gas cooler of a TCRS is utilised to operate a single effect H2O-LiBr VARS. A simulation program is developed for computation of optimum gas cooler pressure of TCRS. The COP and ? ex for individual TCRS and VARS as well as for the combined system have been evaluated. For different values of evaporator ...

Thermodynamic analysis of a hybrid gas turbine/thermoacoustic heat pump/refrigeration engine
Possible performance enhancement of small gas turbine power plants through the application of thermoacoustic systems is examined. The thermoacoustic subsystem is powered only by the waste heat of the gas turbine. Two different gas turbine configurations are considered: a Thermoacoustic refrigerator assisted gas turbine (TRG) and a Combined thermoacoustic heat pump and refrigeration assisted gas ...

Heat recovery from corrosive flue gas
For improvements to energy efficiency in the petrochemical industry, waste heat recovery from corrosive flue gas is the most cost effective source to exploit During the conversion of primary energy, approximately 5-10% of the energy used is lost via hot flue gas. There is no need to emphasise that significant savings are within reach when 60-70% of refining operational costs consist of energy ...

Auxiliary Boilers Can Reduce Cold-Start Times for CCGTs
Combined cycle gas turbines (CCGTs) play a critical role in providing power grids with additional electricity, supporting reliability and resilience during periods of high demand. Combined cycle power plants that harness energy from both combustion and steam turbines use less fuel overall, and can produce longer run times than traditional peaker plants that have long been used to produce ...

What are Incinerator Machines? An idiot’s guide
What is an incinerator machine? An incinerator machine is a mechanical unit that is built to destroy waste. this happens by burning the waste at an extremely high temperature, reducing it to bottom ash. The machines can be manufactured from small garden waste incinerators, all the way to large scale industrial sized machines. Waste of all manners is burned until it is reduced to nothing but ...

Case study - Waste heat generates steam and savings
OVERVIEW A coil coating facility purchased a new a 15,000 SCFM Regenerative Thermal Oxidizer (RTO) which had a nominal heat transfer efficiency rate of 90% thermal energy recovery. It was designed with supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost. The facility was looking for additional ways to decrease their exhaust air temperature ...

SGBI opinion article: shale gas
Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...

Cleaning Up Gasification Syngas
Documento sin título Introduction By definition, gasification is the art of changing a non-gaseous substance, such as a liquid or a solid, into a gas. By this definition, processes such as combustion, anaerobic digestion and pyrolysis would be classified as gasification. However, in today’s world, gasification is defined as any process, which produces a “synthesis gas” or a ...

Oil refinery vapour gas case study
1.0 Evaluation of Refinery Gases Various refinery gases are generated in the process of oil refining. These vary, depending upon the type of crude oil being distilled, such as Reduced Crude distillation, or Naphtha cracker. For the purposes of this case study the description and range of refinery gases are those gases produced from refining Crude Oil and Reduced Crude only. Crude oil is the ...
