ارجو ان تساعدوني في مشروع التخرج بالله عليكم هذا اول طلب لي في المنتدى ساعدوني بليييييز

Your company has recently acquired the production rights to a natural gas field. The upstream production facility is in
the final stages of design and construction will begin soon. The design specification of the upstream facility has shown
that the treated NG will have the following composition:
Name Formula Volume (%)
Methane CH4 85.0
Ethane C2H6 8.0
Propane C3H8 2.0
Carbon dioxide CO2 1.5
Nitrogen N2 2.5
Helium He 1.0
Exploration analysis data showed that our upstream facility will have a production rate of 450 Million SCF/DAY.
Due to the remote location of this resource, a decision by the upper management has been made to investigate the
construction of a complex to convert the NG gas into other products. Initial investigation by our senior engineering team
proposed a possible block diagram for the complex as shown in Fig 1. A number of engineering teams are formed to
study the design and the economic feasibility of this large scale petrochemical complex. Your team is assigned to the
design and economic analysis of two sub
plants of this facility: the syn gas plant and the methanol to olefins plant
(MTO). Your project team shall deliver the following:
1. A preliminary design of the two plants, including estimates of all required utilities and costs (at least one
favorable flowsheet should be developed for each plant).
2. Economic feasibility studies for the plants.

Other Design Data and Information:
1. Syn Gas Plant:
All produced NG will be processed through this plant

Design the syn gas plant to meet the syn gas product ratio (H2/CO) required for the methanol plant (ignore
any requirement for the ammonia and GTL plants at this stage)

Only 35% of the Syn gas products are processed through the MeOH Plant

2. MTO Plant:
Desired products are C2 and C3 olefins

It is unclear that the production of olefins should go through an MeOH synthesis step, other routes must be
considered as they have considerable savings in capital investment

If you decide that MeOH plant is needed, base your calculation on 5200 Mt/Day MeOH feed to the MTO plant
without designing the MeOH Plant
