The Client engaged Rally to replace the entire convection section of the heater, including the stack.
The convection section of an aging naphtha platformer charge heater was crumbling and unsafe to operate. Rally worked with the client to design a new convection section and stack which would be more efficient and safer to operate. The goal was to improve duty and draft whilst still integrating seamlessly with the radiant sections below. Rally modularized the steam drum piping and access platform so that they could be trial fit on top of the new convection section prior to lifting. This streamlined the site work required during a tight turnaround window. All new equipment was designed to meet modern codes and standards, including the multi-blade damper and steam drum.
Material requisitions (MRs) were issued for the new convection section and stack, the steam drum and module, pressure relief valves, modern oxygen analyzers, and other instruments. Construction work packages (CWPs) were produced to reinforce the existing radiant sections, lift and remove the old convection section, execute the lifts of the new convection section, stack, and steam drum module, tie into adjacent piping and wiring, and upgrade instruments.
