Firstly, the gas production characteristics during CSC were analyzed via coal temperature-programmed experiments, and the correlation intensity between temperature and indicator gases at each stage was quantified using the grey relational analysis method. Secondly, SSA was applied to optimize the hyperparameters of the RF model, thus constructing the SSA-RF CSC temperature prediction model. Under the same experimental conditions, the prediction performance of the proposed model was compared with that of five other models. In addition, the applicability of the model was verified using field data collected by the borehole bundle monitoring system. The results show that moisture content exerts a dual effect on the CSC process, an appropriate amount of moisture can promote CSC, while excessively high moisture content will inhibit this process. The mean absolute error (MAE), root mean square error (RMSE) and coefficient of determination (R²) of the SSA-RF model are 1.63 °C, 2.64 °C and 0.9974, respectively, indicating that its prediction accuracy is superior to that of the other five comparative models. Meanwhile, the results of feature importance evaluation of the SSA-RF model are highly consistent with those of the grey relational analysis, which verifies the reliability of the model in screening key indicators. Further verification with field data shows that the SSA-RF model still maintains high prediction accuracy, with MAE, RMSE and R² values of 0.35 °C, 0.45 °C and 0.9898, respectively, demonstrating good engineering applicability.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"209 ","pages":"Article 108586"},"PeriodicalIF":7.8,"publicationDate":"2026-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146146222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is to overcome limitations of neat biodiesel, such as high viscosity, low volatility, and incomplete combustion, while enhancing overall engine efficiency. Five test fuels (D100, B100, 2-EH5 %B100 +NH₃ 5lpm, 2-EH10 %B100 +NH₃ 5lpm, 2-EH15 %B100 +NH₃ 5lpm) were evaluated in a single-cylinder diesel engine operating at 1500 rpm under five brake-load conditions (0–100 %). Combustion parameters, performance metrics and emissions were measured. NH₃ fumigation was supplied at 5 lpm using a controlled intake-manifold system. Combustion analysis demonstrated that B100 exhibited weaker premixed combustion than D100, as evidenced by lower in-cylinder pressure and heat-release rate (HRR) peaks. Under full load conditions, the blend 2-EH15 %B100 +NH₃ 5lpm achieved the greatest combustion, with in-cylinder pressure around 48.05 % higher than B100 and 3.22 % higher than D100. The maximum HRR was nearly 70 % greater than B100 and about 6.7 % higher than D100, indicating intensified premixed heat release near top dead centre. Brake thermal efficiency (BTE) increased by 14.8 % compared with B100 and 3.7 % over diesel, while brake specific energy consumption (BSEC) decreased by 28.7 % relative to B100. Significant emissions reductions in carbon monoxide (CO) by 37.5 %, hydrocarbon (HC) by 11.1 %, and smoke opacity by 35.3 % were observed compared with B100. However, oxides of nitrogen (NO_x) emissions increased by 33.1 %, attributed to enhanced premixed combustion and higher in-cylinder temperatures. The synergistic combination of waste-derived biodiesel, higher alcohol, and NH₃ fumigation enhances combustion phasing, improves thermal efficiency, and substantially lowers major pollutants except NO_x.

The proposed framework combines Gaussian Process Regression (GPR) surrogate modeling, resampling-based data augmentation, and Bayesian multi-objective optimization to simultaneously minimize surface roughness (R_a, R_z) and specific cutting energy (SCE). The resampling-based data augmentation expanded the original experimental dataset (n = 16) to about six times, which significantly improve the accuracy and robustness of surrogate models. As a result, the GPR models achieved high prediction performance with R² values of 0.8680 for R_a, 0.9211 for R_z, and 0.9888 for SCE, while the corresponding MAPE values were 3.25 %, 4.45 %, and 14.73 %, respectively. In addition, Random Forest regression combined with SHAP analysis showed that cutting speed (V_c) is the most influential parameter for R_a prediction (43.4 % importance), whereas depth of cut (a_p, 30.4 %) and width of cut (a_e, 33.6 %) mainly control SCE, which provide useful guidance for parameter selection. Bayesian multi-objective optimization identified Pareto-optimal cutting conditions (V_c = 40 m/min, f_z = 0.07–0.13 mm/tooth, a_p = 0.5–2.0 mm, a_e = 5.1–8.5 mm) that achieved fine surface quality (R_a = 0.55–0.65 µm) while reducing SCE by up to 92.4 % compared to baseline conditions. Experimental validation confirmed good predictive accuracy, with mean absolute errors below 5 % for surface roughness and about 7 % for energy consumption. For a typical P20 mold cavity with 500 cm³ material removal, the optimized parameters can save 0.099 kWh energy and reduce 0.056 kg CO₂ per part, leading to significant annual saving for industrial production. Process safety analysis also indicated that the optimized conditions maintain spindle load below 5 % of rated capacity, increase tool safety factor above 2.0–5.0, and reduce thermal load by 85–92 %, therefore reducing risks of tool failure, machine damage, and fire hazard.

The recently proposed Binder-Pretreated Filtration Process (BPFP) addresses this need by enabling rapid dewatering and producing construction geomaterials; however, the pre-addition of binders causes hydration product loss during filtration, resulting in strength reduction, higher costs, and resource inefficiency. This study quantitatively evaluates the limitations and influencing factors of BPFP and proposes an optimized process with mechanistic insights. Results indicate that BPFP-treated filter cakes exhibit a 19 %–40 % strength reduction at 3 days and 7 %–18 % at 56 days, with short curing time, fast-hydrating binders, high initial water content, and extended pretreatment exacerbating these losses. To overcome these drawbacks, an Enhanced BPFP (EBPFP) was developed by incorporating small amounts of supplementary agents before binder pretreatment. Compared with BPFP, the optimal dosage of each supplementary agent in EBPFP achieved an additional 23 %–36 % strength gain, 11.15 %–20.26 % cost reduction, 17.22 %–20.18 % carbon emission reduction, and improved dewatering efficiency. Microstructural analysis revealed that BPFP-induced strength reduction is attributed to accelerated binder hydration in the high-water-content slurry environment, causing hydration product loss and increased porosity, whereas EBPFP suppresses early hydration, enhances C-S-H and AFt formation, and refines pore structure, thereby improving strength.

Accurate quantification of iodine concentrations and species is crucial for environmental risk assessment. This study introduces a novel combined ICP-MS and UV-Vis method for high-precision measurement of gaseous iodine and sump water speciation. Conventional methods such as IC, ISE, and ICP-OES are limited in detecting ultra-low iodine concentrations in containment environments. While ICP-MS can achieve ppt-level detection, it is mainly suited for total iodine quantification and cannot resolve species due to plasma ionization. UV-Vis spectroscopy, on the other hand, takes advantage of distinct absorption peaks for different iodine species in the UV region, enabling accurate speciation quantification. By integrating these two techniques, this approach simultaneously provides quantitative total iodine measurement and speciation identification, overcoming the limitations of each individual method. Experimental results demonstrate that alkaline spray solutions can remove gaseous iodine effectively and lead to the formation of I₂, I^-, and I₃^- in sump water. ICP-MS enables precise quantification of trace gaseous iodine, with a relative error of + 1.71 % in repeatability tests and a recovery rate of 98.2 %-103.0 %.

Current research in online sludge discharge scheduling is limited due to inaccuracies in existing sludge status monitoring instruments, e.g., sludge level probes and concentration meters, and inadequate modeling of sludge production and distribution in sedimentation tanks.

The ISC prediction for the two sedimentation tanks achieves root mean squared error (RMSE) beneath 0.63 %, while the ESC prediction attains RMSE beneath 0.17 %. Integrating monitoring, simulation, prediction, and scheduling, our solution has the potential to stabilize effluent solids content at our case WTP.
