翻译求助，翻译完加加分啊？

5：the butene storage system contains large amounts of flammable butene. care should be taken to prevent butene leaks.instrumentation is provided to assist in the safe operation of this equipment. alarms are provided to indicate high or low levels and high pressures. a spill is extremely dangerous due to the explosive nature of butene gas. since the gas is heavier than the air it will remain near the ground and concentrate in low areas. 5.丁烯储存系统中有大量易燃丁烯，应警惕丁烯的泄露。仪表可有助于该设备的安全操作，如设置高/低液位报警和高压报警。由于丁烯气体的易爆性，丁烯的泄露是极其危险的。气态丁烯比空气重，泄漏后在地表停留并在地势低的区域富集。

2# bamboobamboo 2:yields: ethylene yields to 84% for ethane, 38% for naphtha and 30% for gas oil may be achieved depending upon feedstock characteristics. （ yield--- 收率 ethane －乙烷 gas oil －柴油 naphtha －石脑油） 产率：根据进料的不同，乙烯的产率不同，由乙烷生产产率可以达到84％；由石脑油生产产率可以达到38％；由汽油生产可以达到30％。 3 ： vent the exchanger to the atmosphere with the globe valve open on the line. （ vent--- 放空； globe valve －球阀） 通过管线上的球心阀可以将换热器排空到大气环境中。

2:yields: ethylene yields to 84% for ethane, 38% for naphtha and 30% for gas oil may be achieved depending upon feedstock characteristics. 产率：以乙烷为原料，乙烯产率为84％；若以石脑油或瓦斯油为原料，视原料性质乙烯产率可分别达到38%和30%。 3：vent the exchanger to the atmosphere with the globe valve open on the line.（vent---放空；globe valve－球阀） 开启管线上的球阀，将换热器放空至大气。

1. heat, as a form of energy, cannot be created or destroyed. heat can be transferred from one substance to another. 热，作为能量的一种形式，既不能被创生也不能被消灭。热可以从一个物体转换到另一个物体。

4. all commissioning operations have been completed, including pressure leaks check, blinds removal, drying and nitrogen purge of equipment and piping interested by process fluids ( venting nitrogen press ure to blow down through psv's by pass and through the drain on the lowest points, pipes and equipment ). 注意标红部分的修饰关系，另外注意中文里的顿号运用： 4. 所有试车操作均已完成，包括工艺流体相关设备与管线的压力试漏、盲板拆除、干燥以及氮气吹扫（通过安全阀旁路以及低点、管线与设备上的排凝口泄放，来放掉氮气压力）。 -----------------------------------------fyi

3：vent the exchanger to the atmosphere with the globe valve open on the line. 3. 球阀开启，换热器通大气。

1.热,作为一种能量形式,不能被创造或者是消灭.但热可以由一种物质传递给另一种物质。 )

5.贮存丁烯体系中有大量可燃的丁烯，应警惕丁烯的泄露。可使用检测仪表来辅助保证该设备安全，如设置操作的上下限报警和高压报警系统。丁烯具有可爆性，它的泄露是极其危险的。另外，丁烯比空气重，泄漏后在接近地面或比较低的位置停留和富集。

大家积极参与啊 我的是份啊

(venting nitrogen pressure to blow down through psv's by pass and through the drain on the lowest points, pipes and equipment). （通过压力安全阀的旁路排放以及管线/设备上的低点放净进行氮气泄压。）
