“…A prime example is the petrochemical industry, where Chen et al (2013) [24] concluded that BSTs and CSTs are competitive options to reduce plant OPEX. Tantisattayakul et al (2016) [25] performed a broader assessment of 35 energy efficiency techniques with data from seven different petrochemical plants in Thailand, concluding that CHP provides the highest capacity to reduce energy consumption and greenhouse gas emissions. Pirmohamadi et al (2019) [26] considered various configurations involving BSTs, CSTs and GTs with an exergetic approach and found BSTs and GTs to provide the most optimal exergetic performance.…”

“…A significant reduction has been achieved in operating cost by 13.8% in the case study, where an existing condensing turbine is modified into an extractive turbine, and one new steam turbine is adopted for generating electricity. Tantisattayakul et al (2016) studied the performance of the energy conservation measures implemented in the Thai petrochemical industry by assessing them from energy, environmental and economic perspectives. The total GHG emission reduction for all sample plants was 502,989 tCO 2 eq/yr, equal to approximately 5.70% of the total GHG emissions from petrochemical plants in Thailand.…”

Malaysia’s energy intensity (GWh/GDP) shows an increasing trend since the 1990s, leading to the government’s efforts to promote energy efficiency via policies such as the National Energy Efficiency Action Plan (NEEAP), which includes the Energy Performance Contracting (EPC) initiative. This paper reviews recent publications in industrial Combined Heat and Power (CHP) with a focus on international case studies relevant to Malaysian industries that use industrial steam and highlights trends within the research area. It also provides the basis for more case studies to be performed in the Malaysian industry to improve energy efficiency while also supporting further academic research in the area. Additionally, the paper documents the importance of data collection and analysis as well as demand forecasting, not only for a better understanding of industrial energy systems but also to increase profitability since system loads may vary throughout a typical year. A multi-criteria and comprehensive approach is recommended in future case studies to ensure energy efficiency, economic returns and environmental impact are considered to ensure long-term sustainability. A summary of barriers to CHP implementation in the industry is also included to provide a broad understanding of industrial CHP.

“…9,10 Within this context Pirmohadi et al 11 demonstrated that in a multiple back-pressure steam turbine system with different pressure and temperature levels, using isentropic efficiency and exergy destruction analysis, the use of gas turbine is more favorable (77%-85%; 1.6-3.6 MW respectively) than condensing turbines (51%-54%; 2.0-4.3 MW, respectively) for the analyzed refineries. Tantisattayakul et al 3 analyzed Thailand's petrochemical industries evaluating six energy efficiency alternatives: 1steam saving and steam loss reduction, 2-steam optimization, 3-cogeneration (CHP), (4-power saving by efficient chillers, and 6-waste energy recovery); among them cogeneration (CHP) had the greatest energy (83.45%) and GHG reduction (82.8%) potential. Ahmadi et al 4,12 assessed the repowering of the existing CHP system, including 3 steam generators, 3 turbo generators (18 MW) and 3 steam levels in the Utilities sector of a petrochemical plant which produces aromatics.…”

Summary Energy efficiency is relevant for the competitiveness and growth of global industries. In this way, simulation studies aiming to increase energy efficiency can be useful for both retrofitting and greenfield projects. Few ethylene process licensors hold the technologies; however, they present different proposals for projects with varying energy efficiency and integration degrees. In the present work, simulation studies of the cogeneration system of a petrochemical plant located in Brazil were performed in order to identify alternative configurations to increase the electricity production without affecting the heat supply to meet the process thermal demand. The cogeneration system of the analyzed plant includes an electric energy conversion system composed of turbo‐generators, back‐pressure and extraction/condensing steam turbines driving electricity generators, compressors and pumps, and heat exchangers. The simulation studies were performed using the HYSYS software to simulate design conditions and validate the model with the actual plant's experimental measurements. New cogeneration configurations were proposed in subsequent simulations, aiming at increasing electricity generation. In addition, exergetic efficiency and environmental analysis of the simulated configurations and an economic estimate for the most efficient proposal were performed. The results showed that the best alternative improved the electricity generation, increased the energy utilization factor by up to 16.2%, reduced greenhouse gas emissions by 22.8%, increased global exergetic efficiency by 28.9% and decreased the steam production and cold utility consumption of the cogeneration system compared to the design conditions.

“…Maupin et al (2014) found that the proportion of water use for thermoelectric power generation accounted for 45% in the USA in 2010. Ali et al (2017) and Tantisattayakul et al (2016) found that the total annual CO 2 emission of Bangkok is about 45.8 Mtoe, and the transportation sector is the main contributor. Li et al (2020) found that the agricultural sector has gradually become an ECW intensive sector.…”

Being a node of the energy-water consumer and carbon dioxide (CO 2 ) emitter, the household is one key sector to pilot integrated energy-carbon-water (ECW) management. This study developed an integrated framework to explore China's provincial household ECW nexus as well as their drivers from the years 2000 through 2016. The absolute amount and growth rate of household energy use (HEU), household CO 2 emissions (HCE), and household water use (HWU) were abstracted to reveal the dynamic characteristics of the household ECW nexus. Efficiency advance, income growth, urbanization, family size, and household number were defined to explain the changes in the household ECW nexus. This study revealed that there is a huge regional heterogeneity in China's household ECW nexus. Developed regions such as Zhejiang, Jiangsu, Guangdong, and Shanghai are the most important household ECW nexus nodes with larger amounts and growth rates of household ECW. Income growth overwhelmingly increases ECW, while efficiency advance effectively curbs its growth. Comparatively, household number, family size, and urbanization have small effects. Therefore, implementing differentiated management and focusing on the synergy of socioeconomic factors are the keys to achieving integrated household ECW management. And the analytical framework can be used to analyze ECW nexus from a sector, city, or country perspective.
