你的侧重点是寻找/优化工艺路线，面试的时候不会问的太详细，给出自己的思路即可。除了工艺路线外，还有很多非工艺的考量：

I guess your scope of work is to provide support for production operations with regards to process operation, optimization and design.

1)Provide day to day support to production operations with regards to process problems and troubleshooting.

2)Review plants and facilities in area of responsibility and propose and implement debottlenecking and operating efficiency improvements.

3)Identify and implement energy efficiency and greenhouse gas reduction opportunities in area of responsibility.

4)Provide process engineering support on HAZOP’s

5)Provide engineering support in the areas of regulatory compliance, and flaring and emissions reporting.

6)A good understanding of applicable piping and vessel codes and standards.

适时的强调自己对安全的考虑，比如说PSV的计算依据，设计的时候考虑到HAZOP。还有对规范的理解和运用，注意欧盟的PED压力设备指导是凌驾于ASME之上，还有他们的防火防爆等级也要熟悉，基本上北美仅要求Class1 Div2的防爆等级，欧洲就要XP。这牵涉到你仪表和马达的选型，选错了欧洲的晨枫们会跳起来

LPG的来源可以是offshore gas,也可以是炼厂气，前者会有冷却>二相或三相分离>De-ethanizer>De-propanizer甚至De-butanizer,回收轻组份后的C4+或者C5+就成了LPG。如果是炼厂气，不需要回收轻组份的话可以直接送到chiller液化，或者是overhead condenser,可以是风冷ariel cooler，也可以利用厂里的循环冷却水shell and tube condenser.

BOC和Air liquide france做不做LPG我不清楚，但是Technip应该是欧洲最大的供货商，你可以去他们的网站看看，即便是最简单的PFD也会有帮助，中国人聪明，很多东西一点就通。
