Process design is intended to include:
1. Flowsheet development.
2. Process material and heat balances.
3. Auxiliary services material and heat balances
4. Chemical engineering performance design for specific items of equipment required for a flowsheet.
5. Instrumentation is related to process preference.
6. Preparation of specifications.
7. Evaluation of bids and recommendations of qualified.

Design Development Stages:
- the design objectives (the need).
- setting the design basis (data collection).
- generation of possible concepts (solutions).
- build preference model and fitness testing.
- economic evaluation, optimization, and selection.
- detailed design and equipment selection.
- procurement, construction, and operation.

Design constraints
A. Internal constraints: over wich designer has some control.
B. External constraints: fixed, invariable.

Flow-sheet Importance:
- shows the arrangement of quipment selected to carry out process.
- shows the streams concentrations, flow rates& compositions.
- shows the operating conditions.
- during plant start up and subsequent operation.

- الرساله ؛ عمليا الفنان و المهندس بينهم تشابه باماكن خلق عالم
بس اكو فرق ينطي ميزة لكل واحد
المهندس لما يغير العالم او يخلق عالم جديد فـ هذا تغيير اجباري لا بد منه ( يسيطر على الجميع ) و هاي جمالية الهندسة
اما الفنان فـ يگدر يخلق عالم خاص و يكون لاشخاص محددين و هاي من أهم مميزات الفنان انه يبرع بخلق ملاجئ
