Summary: In order to produce clean and cheap power, it is necessary to develop new technologies or improve existing processes based on sustainability criteria and alternative fuels. The integration of sustainability into process design helps eliminate or minimize negative effects. However, measuring sustainability performance and decision-making are crucial and challenging steps in developing sustainable industrial processes. This study introduces the framework of Methodological Sustainability Assessment to Process Intensification (MSAtoPI) as a methodological approach with appropriate sustainability indicators, which effectively analyzes and communicates complex process operations, and demonstrates its effectiveness in a biomass-based process for clean power production.

Summary: This study compared the environmental impacts of four typical propylene production routes in China using the life-cycle assessment methodology. The results showed trade-offs across nine environmental dimensions, making it difficult to rank the environmental advantages of each production route. Raw materials consumption was found to dominate the environmental burdens of the different routes, with the highest environmental loads in the coal to olefin process. The findings highlight the need for close attention to the feedstock shift in the propylene industry to promote environmental sustainability in the Chinese chemical manufacturing industry.

Summary: This paper proposes a mathematical programming formulation to optimize the configuration of water and CO2 in shale gas hydraulic fracturing operations. The aim is to minimize the total annual cost while considering water availability and CO2 generation. The results show that increasing the percentage of CO2 in the fracturing fluid can reduce freshwater requirements but increases the overall cost, and the availability of freshwater has an impact on the optimization.

Summary: In this study, deep learning models based on a multilayer perceptron are developed to forecast 12 month cumulative produced shale gas and 90 day produced flowback water using data from the Eagle Ford Formation. These models provide important references for decision-makers in drilling new wells. Input variables such as latitude, longitude, true vertical depth, lateral longitude, total proppant, and total fracture water are used. The trained models are then evaluated in the Burgos Basin to analyze energy benefits, freshwater consumption, and flowback water produced through well drilling in Mexico. The results show that the multilayer perceptron models perform well with high coefficient of determination and low mean absolute error values for the validation set.

Summary: This paper proposes a novel mathematical programming approach that combines mixed-integer nonlinear programming with machine learning models for determining operating conditions, gas production, and optimal water management in shale gas fields during the completion phase. The dataset used for developing the artificial neural network model is collected from the Eagle Ford Texas formation, selecting total cumulative gas production and flowback water as output variables. The mathematical optimization model considers machine learning models, mass balances, treatment, storage, reuse, and disposal options, as well as well location selection and economic indicators from shale gas sales. A case study demonstrates the benefits of the proposed approach, which achieves a water consumption of 6.71 L/GJ and allows for 27% of the required fracture water to be obtained through flowback water reuse, with attractive economic indicators.
