Hello everyone,

My name is Rifka Aisyah. I have total six years experience working as process and project engineer (2011-2017). You might think I’m no longer young. But, I feel I’m still, so I will not change the header of this blog. 😀

Currently I am looking for opportunities to work as process engineer again since I have resigned from my previous company in Bandung, West Java, Indonesia. I resigned on May 15, 2017. I keep myself busy by reading, blogging, and helping my friends.

I start writing this blog again since August 2016 after vacuum for a quite long time. The motivation behind this was actually I’m not busy enough in my work (just kidding!) and I also want to do something I like that can define myself.

As process engineer, I worked in variety of fields, starting from carboxymethyl cellulose (CMC) industry, ferronickel, turpentine, enzyme industry, and oil and gas industry. I also involved in various project, starting from:

- Front-End Engineering Design
- Feasibility study (pre-feasibility and feasibility study)
- Energy audit
- Engineering, Procurement, and Construction
- Precommissioning activity

I realized that if I don’t write what experience I got from work, I will forget them all. So, I start writing in this blog.

Hi Rifka, this is greeting is from Tony, I am a process engineer as well, now I am working with a middle sized engineering firm based in China.

Nice blog, you have pen down your experience and findings which is helpfull for young engineers !!

Saya dosen di ITB. Saat ini saya sedang mengerjakan proyek pengembangan mini refinery bersama dengan beberapa universitas dan institusi dari Korea. Saya tertarik dengan tulisan Mbak Rifka tentang Mini Refinery Review. Boleh kontak lebih lanjut? Siapa tahu bisa kerjasama. Terima kasih.

Molecular weight of gas= 17.5

z=0.99

Suction pressure=800 psia

discharge pressure= 1097 Psia

Suction Temperature= 540 R

Flow= 200 MMSCFD

Compressor efficiency=85%

What HP is required=???????

I will wait your reply.
