1. What are the important points to be considered in an equipment drawing with respect to the process and plant layout?

2. You have been asked to select pipe for use within a chemical processing plant.

(a) What information do you need to know from the process engineering department to select suitable pipe ?

(b) What information do you need to know from the civil structural engineering department to select suitable pipe ?

Important points to be considered in an equipment drawing with respect to the process and plant layout:

1. The type of the process with capacities. Process flow diagrams.

2. Site location, topography, weather conditions and environmental conditions

3. Process equipments, mass flow rates, heat transfer rates, storage capacities etc,

4. Sources of water supply

5. sources of Power and other utilities.

6. If captive power plants are rewuired, their layouts

7. Effluents to be handled, treated and disposed off.

8. Wind direction, temperatures, thunderstorms, rains, lightenings and their protection, and earthquake protection.

9. Transporation arrangements for receiving raw materials and dispatching fininshed products by rail, road etc.

10. Storage areas required like tanks, open areas, and covered areas.

11. Areas of plants and equipments requireing covered areas,

12. Process heating, cooling and refrigeration etc required if any.

13. ease of construction, operation and maintenance.

2.a)The information do you need to know from the process engineering department to select suitable pipe:

- commodity/product, pressure, temperature, type of reaction/process, environmental conditions

(b) The information do you need to know from the civil structural engineering department to select suitable pipe:

- location of pipe like open or covered area, underground, type of holding/fabrication techniques, weather conditions.

-standard catalogues of various pipes of various manufactures, price lists, delivery times etc
