Hydrogen Tank Relocation Project
Honeywell Aerospace (Southborough, MA)
​Problem:
At the start of 2021, Honeywell Aerospace had a safety walkthrough at the Southborough site. Following this walkthrough, the team deemed it necessary to move a hydrogen accumulator tank that was located close to an exit/entrance which could pose a safety hazard.
I was tasked with moving the accumulator tank from its current position along with two additional auxiliary high pressure hydrogen tanks used for testing, to a new location closer to the hydrogen electrolyzer.
Objective:
Create a P&ID document outlining the layout of the system, how it would tie into the buildings existing framework, and what fittings, valves, gages, and regulators it would consist of.
Design and order 3D printed parts as well as off the shelf items to complete the assembly.
Build the assembly keeping pressure safety tips in mind.
Test for leaks and perform a final walkthrough before tying the assembly into the electrolyzer and the main buildings framework.
​
Process:
Created a P&ID with insight from Honeywell managers and careful research into specific products to provide an overall system outline.
Upon review of the P&ID, built the system according to standards required by the division by ordering necessary parts, and assembling the design with hand held tools.
Tested the final assembly with leak test techniques and proper testing procedure first at low and then at operating pressures before replacing any leaking or faulty components that did not pass inspection.
Skills Demonstrated:​
Knowledge of how to create P&ID documents in SolidWorks.
Use of basic tools such as drills, taps, de-burring tools.
Knowledge of how to cut and bend stainless steel tubes as well as assemble and disassemble Swagelok compression fittings.
Outcomes:​​​​
Built assembly faster than anticipated to fulfill the safety guidelines set out by the company.
Learned how to test complex high-pressure systems as well as how to pressurize and depressurize certain portions.
Learned how to set a relief valve to crack at a certain pressure.
Learned how to bend tubes and affix tubes at high heights to concrete walls.
Added an additional portion of the line to allow for an outside hydrogen line which helped to facilitate outside drone testing and provide further safety measures.
