“…On the other hand, the Modified Henderson-Pabis model presented the best fit quality because higher values of R 2 , the lowest values of F-test and RMSE and represented an excellent tool for estimating the drying time during pneumatic transport of malt bagasse using different temperatures in both layouts(Figures 6 and 7). These results are in agreement with works reported in the literature[32][33][34], which evaluated the behavior of waste drying as a function of time.Prediction of drying rate and drying time are important aspects of kinetic models and based on statistical results, the modified Henderson-Pabis model can be used safely for this type of malt bagasse drying. The fact that the Henderson-Pabis model has three exponential parameters, which provides a better mathematical approximation of the experimental drying kinetics, could be associated to the fact that the model better fitted the experimental data.…”

Malt bagasse is a by-product of the brewing industry that has high moisture making it very unstable and susceptible to fast microbial deterioration. This work evaluated drying kinetic models of malt bagasse during pneumatic transport with air flow at 30, 45 and 60 ºC and layout of 4.5 and 7.0 m. The results showed that the decrease of moisture from malt bagasse was favored at higher air temperature due to the higher diffusion coefficient. In the ranges measured, the values of the effective moisture diffusivity and heat transfer coefficient were obtained between 2.05×10 −10 to 12.74×10 −10 m 2 /s and 175 to 363 W/m 2 K, respectively. Average energy for liquid diffusion in the malt bagasse drying process was 44.30 kJ/mol. Pneumatic transport with air flow at 60 o C and layout of 7.0 m reached rapidly the final moisture of 12% (w.b), which it may reduce transport costs and allow long periods of stable storage for malt bagasse. The statistical tests results showed that the experimental datas presented excellent fit using the Modified Henderson-Pabis model, in the temperature range for both layouts.

The negative impact on the environment from drill cuttings resulting from drilling wells for oil production is assessed in this article. Environmental hazards are contaminants such as petroleum products, drilling fluid reagents, and chemical compounds of heavy metals that make up drill cuttings. To assess the negative impact, the heavy metal content indicators and chemical analysis parameters of drill cuttings were determined. It has been established that there are no excesses in the standards for the content of heavy metals in drill cuttings. The results of chemical analysis showed that there are excesses in values: MPC (Maximum Permissible Concentrations), COD (Chemical Oxygen Demand), oil content, solids, hardness, magnesium and calcium ions, chlorides. Two directions of utilization of drill cuttings were selected: the use of drill cuttings in the construction of the foundation of the road, and obtaining material based on drill cuttings to strengthen slopes. A technoground was obtained in the form of a lumpy material for placement in a barn and further excavation for filling embankments and strengthening soil. In preliminary studies, it was found that theb technoground sample with the following component composition has the most stable strength characteristics: cement - 20%; drill cuttings - 80%; liquid glass - 2% over 100% of the mixture. Keywords: drill cuttings, negative impact, environment, utilization, technoground

“…Based on the mechanism of heat transfer that is employed, drying is categorized into direct (convection), indirect or contact (conduction), radiant (radiation), and dielectric or microwave (radio frequency) drying. Although more than 85% of industrial dryers are of the convective type, contact dryers offer higher thermal efficiency and have economic and environmental advantages over convective dryers [10,11]. Rising energy costs, compulsory legislation on pollution, working conditions, and safety, have a direct bear upon the design as well as selection of dryers [9].…”

“…Rising energy costs, compulsory legislation on pollution, working conditions, and safety, have a direct bear upon the design as well as selection of dryers [9]. Table 1 shows the classification of dryers based on various criteria [9][10][11][12]. In this work, an experimental study was performed on the drying of drill cuttings containing water-based drilling fluids with the two drying systems-microwave and conveyor belt dryers.…”

Drill cuttings, contaminated with drilling fluids, are characterized by their high moisture content, which can cause problems for collection, storage, and transportation. Additionally, the practice of disposing waste with high moisture content into sanitary landfills is undesirable and mostly forbidden. For that reason, drying of waste with high moisture content, such as drill cuttings, is an essential operation. In this work, microwave and conveyor belt drying processes for drying drill cuttings containing water-based drilling fluids were examined in a lab-scale study. The results of the study indicated that the microwave dryer has been shown to be advantageous in terms of time and energy consumption for drying of thin film layers, while the conveyor drying system was more appropriate for bulk drying.
