do not forgot the drawing

Question 4. [20 marks) Imagine that you have been assigned to an LCA team working for the Canadian CIRAIG company. The project is about the environmental assessment of the process dealing with the conversion of natural gas into synthesis gas (H2 and CO mixture). The team aims to identify all of the requirements needed at each LCA stage. Your part deals with gathering all needed information associated with raw material extraction and processing. Draw (i) a general schematic of a typical LCA scope and (ii) a flow diagram for raw materials extraction and processing. Then, answer the following questions: a) What are the raw materials needed to conduct such a study? Provide two examples. b) List two processes that could be employed for refining of raw materials. Explain briefly the mechanism of each process. c) Provide two examples related to physical and chemical characteristics of the refined materials. 15 marks for drawing the general schematic, 5 marks for drawing the specific schematic, 3 marks for listing raw materials, 5 marks for listing and explaining processes, 2 marks for listing examples on properties
