摘要
提出了秩化数和秩化度的定义,用以评价焦化流程的秩序优劣,并以传统煤气净化流程、低品质硫磺和脱硫废液混合制酸工艺以及相应的改进工艺为例进行了分析。相对于传统煤气净化流程,提出了改进的煤气负压净化流程,通过分析可知,负压煤气净化流程的秩化数比原有煤气净化流程的秩化数从0.025提高至0.067、秩化度从541提高至1 190,流程缩短且能耗降低;相对于低品质硫磺和脱硫废液混合制酸工艺,提出了低品质硫单独制酸-脱硫废液分解联合工艺,后者流程的秩化数虽有所降低,但秩化度从596提高至11 133,过程能耗大幅降低。
In order to evaluate the coking process order,the serialization number and the serialization degree were defined. The analysis was made by taking the example of traditional coke oven gas purification process, the sulfuric acid making process by mixing low quality sulfur and desulfurization waste water and their modified processes. Based on the traditional coke oven gas purification process,the improved negative pressure gas purification process was presented. Through comparison of the results of two processes ,it was shown that the serialization number increased from 0.025 of the former to 0.067 of the latter and the serialization degree increased from 541 of the former to 1 190 of the latter,with process shortened and energy consumption reduced. Similarly, based on the sulfuric acid making process by mixing low quality sulfur and desulfurization waste water, the combined process of sulfuric acid making process only with low quality sulfur and decomposition of desulfurization waste water was presented. Through comparison of the results of two processes, it was shown that the serialization number of the latter was lower than the former but the serialization degree increased from 596 of the former to 11 133 of the latter, greatly reducing the process energy consumption.
