“…The main technical route of this project is to use the clean electric energy of photovoltaic power plants to electrolyze water to produce hydrogen and then combine hydrogen and enriched carbon dioxide to produce methanol. The project plans to construct an annual output of 1,000 tons of methanol, about 1500 tons of carbon dioxide, and an annual demand of about 200 tons of hydrogen [21].…”

Objective: The electricity-to-hydrogen technology can convert surplus renewable energy electric energy into chemical energy. Hydrogen plays an important role in transportation, power generation, and other fields. Therefore, developing electrochemical (P2X) technology for renewable energy consumption effectively solves renewable energy curtailment. Methods: The four aspects of market scale, technical route, energy conversion efficiency, and demonstration project progress are reviewed, and the energy efficiency of the four electrochemical technologies is compared, Power consumption, marginal electricity price, equivalent output, and market share five major technical and economic indicators. To analyze the strengths, weaknesses, opportunities, and threats of P2X in China, a literature review survey was conducted, relying on recent two-decade publications from four main publishers: Scopus, Springer, Wiley, and Taylor and Francis. Keywords were selected from the first-hand references based on their impact on P2X or related topics listed in the literature databases. The keywords as Power to X, Power to chemicals, PtX, and P2X were chosen according to their actual involvement or keen interest in P2X projects. Results: The research results based on the low-temperature electrolysis technology route show that the comprehensive energy efficiency of the electricity-to-methane and electricity-to-gasoline technologies is higher (50%); the electricity-to-gasoline technology is the most economical (marginal electricity price is 0.37 yuan/kWh), but the synthesis process requires carbon monoxide and carbon emissions, And the technical risk is high; the promotion of electricity to ammonia will have the greatest impact on the market (17.18%). Reducing coal consumption by about 22.85 million tons and the environmental protection significance of electricity-to-ammonia conversion (reducing carbon emissions by about 39.1 million tons) are two important directions for future electrochemical technology. Conclusion: Facing the development of P2X technology in the future, the plan and economics of the high-temperature electrical and chemical technology route based on high-temperature solid oxides were preliminary discussed and prospected.

“…Reactors with built-in heat recovery systems are most commonly used for traditional ammonia synthesis [118], in which hot reaction products heat the reactants to the required temperature. The authors of the final paper in this theme, Tovazhnyanskyy et al [52], reported on "Optimal Design of Welded Plate Heat Exchanger for Ammonia Synthesis Column: An Experimental Study with Mathematical Optimisation". They investigated heat transfer in a plate heat exchanger with a specially welded construction for use in ammonia synthesis.…”

Energy is a fundamental element supporting societal development, particularly with the increasing dependency on the Internet of Things. It is also the main contributor to environmental impacts and subsequently, a potential sector for mitigation. Sustainable energy system design considers energy savings and energy efficiency, waste and consumption reduction, process efficiency enhancement, waste heat recovery, and integration of renewable energy. Emerging tools range from advanced Process Integration, modelling, simulation, and optimisation, to system analysis and assessment. This review covers selected emerging studies promoting sustainable system design, including the recent developments reported in the Special Issue (SI) of the 22nd Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES’19). The primary emphasis was to enhance the economic and environmental performance. However, social factors were also highlighted as essential for future sustainable development. The discussion and analysis in this review focus on the most recent developments of (a) heat integration and heat transfer; (b) integrated and newly developed heat exchangers, (c) integration of renewables, and (d) roles in economic and environmental sustainability. The key results are highlighted, and future research ideas are suggested according to their links to a broader context.

In the oil and gas industry, heat exchangers are subject to loads that cause malfunctioning. These loads are divided into thermal and mechanical stresses; however, most efforts are focused on studying thermal stresses. The present work reduces mechanical stresses by mitigating pressure events in a gasket plate heat exchanger (GPHE). GPHE requires that the hot and cold stream branches have approximately the same pressure. Thus, the work focuses on controlling the pressure difference between the branches. A test bench was used to emulate, on a small scale, the typical pressure events of an oil production plant. A control valve was used in different positions to evaluate the controller. In the experiments, it was observed that the best option to control the pressure difference is to use a hydraulic pump and control valve in the flow of the controlled thermal fluid branch. The reduction in pressure events was approximately 50%. Actuator efforts are also reduced in this configuration.
