- Since we are talking about the hydrocracker reactors, it is worth concluding my presentation with this Point of Interest; YERP has adopted the recent ASME Code Standard 2007 which started to be mandated for newly designed equipment after 01 July 2009. YERP reactors are basically designed using an alloy material of Chromium, Molybdenum and Vanadium. The new ASME Code 2007 included detailed information about utilizing this vanadium enhanced material such as the allowable stresses and the fatigue properties that were not included in the 2004 ASME Code. As a result of this adoption, 15% less material will be used in the shell and head of the reactors Additional cost savings may be realized for transportation, foundation, and erection With no impact on the mechanical integrity of the two reactors Also, it worth mentioning that effective immediately after adopting of this ASME standard on YERP hydrocracker reactors, CLG is using the 2007 ASME Code Case for reactors design. <Click> Informational items: The new 2007 Code Case will not impose any stricter inspection requirements than is currently required by the YERP procedures using the 2004 code. The new 2007 Code Case will be mandatory for purchase orders issued to vessel manufacturers issued after 01 Jul 2009 , the study showed that two cranes are required for remedially lifting the 2nd stage reactor which weighs 584 ton. The main crane with a capacity of 1350 ton will used to lift the top head and the tailing crane will be used to control the bottom head at the ground level. This tail crane weighs 600 ton.
- YERP team has captured the opportunity of starting the detail engineering design with the advent of the new CLG standard requirements for the ADS system. CLG has performed a review for the Automatic Depressuring Systems (ADS) that are employed in CLG refineries as well as numerous licensed units. Inherent to this review are changes to the safety shutdown systems, which turn into recommendations relate to inputs to the ADS systems. Many plants have successfully implemented these recommendations with a proven history of safe and reliable performance. Accordingly, CLG has modified the ADS system to incorporate these recommendations. All the newly designed hydrocracker plants will be applying this new ADS standard including Luberef and Jizan The ADS modification requires: Adding four additional inputs to activate the ADS system in case of: Voting of any 2 bottom bed TIs in hydrocracking service Voting of 2-out of 2 TIs at High-high temperature on the reactor outlet Losing of RGC Reeducation of Make-up hydrogen Also, around 74% of the total inputs will be eliminated in order to avoid any spurious trip for the unit. The eliminated inputs will include: The skin TIs since it has been proven that the skin TIs would not have been an adequate trigger point in every case of high temperature event. Also, the elimination includes also the top bed TIs since the trip inputs have been limited to the locations where the temperature excursion can be detected earliest. Since the hydrotreating catalyst beds do not carry the same level of risk of a temperature excursion as hydrocracking catalyst, the hydrotreating bed TIs have been also excluded from giving inputs to the ADS system.
