摘要

沼气升级是提高沼气热值和提高生沼气质量的关键。本研究旨在研究近大气压水洗涤(NAPWS)系统在使用吸附和吸收技术的同时用于沼气升级的最佳性能。这是通过两个阶段的过程实现的:即田口方法和响应面方法。田口正交阵列设计由27次运行组成,实验研究了原料沼气压力(10-30kPa)、液体流速(2.6-4.2l/min)和吸附柱中钢丝棉高度(0-45.72cm)的变化对甲烷(CH4)产量和硫化氢(H2S)和二氧化碳(CO2)的去除效率的影响。实验表明,硫化氢的去除率大于87%,平均生物甲烷含量为77.67%。在第二阶段,对工艺参数进行了方差分析和RSM优化。在14kPa的气体压力、4.2l/min的液体流速和13.31(%v/v)的CO2浓度下。,通过数值优化得到钢毛高度为22.86cm。这些结果表明,田口和RSM的使用产生了最佳的系统性能,其中液体流速是最重要的因素

Optimization and Analysis of a Low-Pressure Water Scrubbing Biogas Upgrading System via the Taguchi and Response Surface Methodology Approaches
Biogas upgrading is essential in order to increase the calorific value and improve the quality of raw biogas. This present study aims at investigating the optimum performance of a near atmospheric pressure water scrubbing (NAPWS) system for biogas upgrading while using both the adsorption and absorption techniques. This was achieved through a two-stage process: namely, the Taguchi approach followed by the response surface methodology (RSM). The Taguchi orthogonal array design consisted of 27 runs where the raw biogas pressure (10 - 30 kPa), liquid flow rates (2.6 - 4.2 l/ min.) and variations of the steel wool height (0 - 45.72 cm) in the adsorption column were experimentally studied with respect to the methane (CH4) yield and removal efficiency of hydrogen sulfide (H2S) and carbon dioxide (CO2). From the experiments, the removal efficiency of hydrogen sulfide was greater than 87% with the average bio-methane content of 77.67%. During the second-stage, the analysis of variance (ANOVA) and the RSM were undertaken for optimization of the process parameters. The optimum bio-methane concentration of 84.71 (%v/v) CH4 and 13.31 (%v/v) CO2 was attained at gas pressure of 14kPa, liquid flow rate of 4.2 l/min., and steel wool height at 22.86cm obtained through numerical optimization. These results revealed that the utilization of the Taguchi and the RSM yielded to the best optimal system performance with the liquid flow rate as the most significant factor
