PROCESS DESIGN PRACTICE 1 CHEM4007A Report 2 Acrylic acid By Student’s Name 1: Ahmed Said Al-Balushi SID: 151847 Student’s Name 2: Haitham Jumma Al Mashaikhi SID: 151865 Student’s Name 3: Mazin Ahmed Al mamari SID: 161054 A design project submitted to the faculty of engineering In partial fulfillment of the requirements for The process design course CHEM4007A&B Faculty of Engineering Department of Chemical Engineering Sohar University 2018-2019 PROCESS DESIGN PRACTICE CHEM4007A 2 Acknowledgment We would like to thank and appreciate the help and contribution of everyone who helped us to finish this project successfully. We would like to specially thank Dr. Youssef for his continuous help and gaudiness throughout the semester. PROCESS DESIGN PRACTICE CHEM4007A 3 Executive summary This report is going to discuss the process of producing acrylic acid through designing a detailed simulation of each equipment of the process. The process contains various equipment‟s starting from a gas compressor and going through a reactor, absorption columns, a distillation column, heat exchangers and pumps. Each equipment detailed design will be performed individually a long with the short cut design of the equipment. Besides that, a survey of each equipment is written showing how the equipment works and a discussion on its classifications. Finally, a comparison of the calculated data will be provided to show the percentage of error through comparing the simulation calculated data and the data obtained from references.
