炼油

In fact, a refinery is essentially a group of manufacturing plants that vary in number with the variety of products produced; refinery proc esses must be selected and products manufactured to give a balanced operation: that is, crude oil must be converted into products according to the rate of sale of each.

实际上，炼油厂从根本上说是一组生产装置，其数量根据生产产品的不同而不同。炼油工艺须经选择，产品生产应该平衡：即从原油生产产品必须依据每一产品的销售速度而进行。

The characteristics, status of production and application, developing prospects, technical headways and problems in industries of biological catalyst, biological plastic, biological pesticide, biological fertilizer, biological oil refining, biological environmental protection and traditional biochemicals were also discussed.

结合生物工程的发展趋势，概述了生物技术在石油化学工业的应用领域，探讨了生物催化剂、生物塑料、生物农药、生物化肥、生物炼油、生物环保及传统生化产品等行业的特点、生产应用状况、开发前景、技术进展及存在的问题。

Injurants do some harm to the respiratory system health and the damage is aggravating with the increase of working years.

结论炼油污水工作环境对工人呼吸系统健康有影响，且随着工龄增长而加重。

That adds to the cost of extracting oil, because more engineers and more complex machinery are needed to exploit it—but the end of easy oil is a far remove from the jeremiads of peak-oilers.

因为需要更多的工程师和复杂的设备来开采石油，炼油的成本增加了。但是，易采石油的末日还远不是鼓吹&峰值石油&的石油商们所忽悠的那样。

Low-boiling phenols in low-temperature coal tar are important chemical raw materials. For the identification and determination of the individual phenol boiling below 210℃ in the low temperature coal tar, the methods of gas chromatography, liquid-liquid chromatography followed by ultra-violet analysis and fractional distillation followed by infrared analysis were evaluated and compared.

随着煤炼油工业的发展，煤焦油中的酚类，特别是低級酚，作为化工原料的利用很重要，我們应用(1)气液色譜法，(2)液液色譜与紫外光譜法結合及(3)精餾与紅外光譜法結合三种不同方法对210°以前的低級酚进行了各种异构体的成分分析，比較分析結果：三种方法对同一样品进行分析时，最大絕对誤差在2％以内，其中以气液色譜法最为快速，液液色譜法次之，精餾-紅外光譜法費时間較多；但后二种方法所得数据較完全。
