    Experiments were carried out in two separate sieve-plate towers with three and five plates each respectively. Hydrogen sulfide in coal gas. was found highly absorbed in those towers by lime suspension in the range of relatively high gas velocity with the suspension reaching stage of foaming. Results show that both the average height of foam (H) and the mass transfer coefficient (K) are proportional to gas velocity in tower (W) and relative quantity of lime suspension (1), expressing in liters...

    Experiments were carried out in two separate sieve-plate towers with three and five plates each respectively. Hydrogen sulfide in coal gas. was found highly absorbed in those towers by lime suspension in the range of relatively high gas velocity with the suspension reaching stage of foaming. Results show that both the average height of foam (H) and the mass transfer coefficient (K) are proportional to gas velocity in tower (W) and relative quantity of lime suspension (1), expressing in liters per cubic meter of coal gas, in definite mathematical relationship. Under definite conditions, absorption of H_2S reaches over 90%. Results also show in the absorption process, CO_2 of coal gas is being only slightly absorbed. Comparing with Thylox and iron-soda processes, the cost for sulfur removal of coal gas in each case is approximately the same. However, the present process actually has distinct advantages over the others in low capital cost, requiring less steel, process being simpler and absorbent being easily obtainable. The disadvantages pertaining to the present process are lime suspension being not fully reacted and utilization of the used suspension being difficult. The present process is being recommended to be applicable to sulfur removal of coal gas from generators of medium size and also in preliminary stage of sulfur removal of synthesis gas.

    以便宜易得的石灰乳为脫硫剂。采用泡沫法,在装有五块和三块篩板塔中,对煤气进行了强化脱硫試驗。由試驗結果得出塔板上泡沫的平均高度H以及传貭系数K分別与煤气空塔流速W和石灰乳比用量l(每米~3煤气所用的石灰乳升数)相互关系的数学公式。在一定条件下,脫硫效率可达90%以上,試驗結果还指出脫硫过程中CO_2被吸收的量很小。本法在工业上应用时,如与砷碱法或鉄碱法相比,成本不相上下,但是本法具有基建投資低,鋼材用量少、工艺流程簡单和原料易得等优点,缺点是石灰乳的利用率不高,用过的石灰乳的处理較困难。对于中小型企业的燃料煤气的脫硫以及合成煤气的第一段脱硫,本法值得推广使用。

    The procedure and accuracy of the methods of ammonia nitrogen determination in wastewater with gas-sensing electrode and air-gas electrode were studied. In the procedure, the sample needs generally no pre-treatment and can be determined directly. The concentration of ammonia nitrogen should be in the range of 0.2~200mg/1 as other selective electrode methods, these methods are rapid. simple and accurate.

    The combustion characteristics of methane gas are stated in this article. Pèrformance tests and evaluation were made for the daily used methane gas domestic range burners. The main problems existed have been analyzed. In order to improve the flame stability and raise the heat efficiency experiments have been carried out by means of various methods, and on this basis the totally aerated(primary air)burners for burning methane gas were made in help of our cooperative unit. Test results have indicated that under rated load, the heat efficiency of the new burner is 30~50% higher than that of the ordinary ones. All the influencing factors have been analyzed and suggestions for further raising the heat efficiency of methane gas energy are presented.

    本文阐述了人工沼气的燃烧特性,对目前常用的人工沼气燃烧器进行了性能测试和评价,分析了存在的主要问题。试验了各种提高燃烧稳定性和热效率的途径,在此基础上,提出了用全一次空气燃烧器燃烧人工沼气的论点,并由有关单位协作进行了试制。测定结果表明,这种燃烧器在额定负荷下的热效率比目前常用的燃烧器提高30—50%。最后对各种影响因素进行了分析,提出了进一步提高沼气能源使用热效率的意见。
