乙烷

Production technology and market analysis of ethylene dichloride and vinyl chloride monomer

分析了世界二氯乙烷的生产消费现状及发展前景，指出了发展趋势。

In China, the main producers of ethylene dichloride are Beijing Huaer Company Limited, Jiangsu Danhua Corp Co., Ltd. and Shandong Luyue Chemical Company.

我国二氯乙烷的主要生产厂家有北京化二股份有限公司、江苏丹化集团有限公司和山东鲁岳化工有限公司。

The worldwide production capacity of ethylene dichloride was 47 468 kt/a in 2005,while the global market demand was 39 037 kt.

2005年，全球1，2-二氯乙烷生产能力约为47 468 kt/a，需求量约为39 037 kt。

When the concentration of tested gases was 2000 mL/m3, chloroform, ethylene dichloride, formaldehyde and benzene did not interfere with the determination of acetone.

当各测试气体浓度均为2000 mL/m3时，三氯甲烷、二氯乙烷、甲醛和苯气体不干扰丙酮的测定。

Dioxane has been found in at least 27 of the 1,662 current or former NPL sites.

在所有1662处当前或以前的重度污染区中，检测到1，4-二氧杂环乙烷污染的至少27处。

Dioxane is a byproduct of a petrochemical process called ethyoxylation, which involves using ethylene oxide to process other chemicals in order to make them less harsh.

1，4二氧六环的副产品是一个石化过程被称为ethyoxylation ，其中包括利用环氧乙烷，其他化学品，以使它们显得温和。

In the study of by-product dioxane in polymerization reaction of EO,it is found that the effect of solvent is very small.And so do the catalyst BF_3-H_2O complex and catalyst H~+.

计算结果也解释了BF_3-H_2O催化环氧乙烷聚合产物分子量达到某一极限值后不再增加，消耗的单体都生成了二氧六环的原因。

Fairly good control results were obtained when the control scheme was applied to a distill...

将该方案应用在工业脱乙烷塔的控制中得到了令人满意的结果。

The risk assessment for epoxyethane /glycol plant of Maoming Petrochemical Ethylene Industrial Comˉpany was carried out by utilized the risk assessment proceˉdure of risk index method of fire and explosion of Dow Chemical Company,and improvement measures are sugˉgested.

利用道化学公司火灾爆炸危险指数法安全风险评价程序对茂名石化乙烯公司环氧乙烷/乙二醇装置进行了安全评价，并提出了改进措施。

The results indicate that SPE has high activity and good selectivity of EG in hydration reaction of EO .

结果表明，磺化石油焦活性炭对环氧乙烷水合反应有很高的活性和乙二醇选择性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
