Dear sir, We have uploaded GAD with corrections. Following are some additional comments 1)Minimum shell thicknesses are 2.8 mm, 2.8 mm, 2.8 mm, 3.8 mm, 3.8 mm & 2.8 mm for equipment no. (item no.) 2, 3, 7, 8, 9 & 17 respectively. 2) Tube thickness of 1.6 mm is considered. 3) for equipment no. 10 (condenser) as vapor will be on shell side, so shell will be considered as contact part. 4) We don't need monitering  of each section of Stripper column, hence SG/LG  are not provided for individual sections. You will be getting the Base load drawings by today.
