Feed basis and operating cases
Review the gas composition, flow cases and operating conditions supplied for the enquiry. Identify missing information, conflicting assumptions and changes between the process basis and equipment documents.
Possible output
An input and assumptions register identifying the information needed to complete the assessment.
Required gas conditions
Review how the intended gas use and stated outlet requirements are represented in the design basis, process documents and supplier proposal. Clarify which requirements apply at each interface and which conditions require confirmation.
Possible output
A requirements review note with specific questions for the relevant parties.
Equipment requirements and proposals
Examine process-side datasheets, proposed equipment duties and supporting technical information against the agreed basis. Record differences between the requested scope and proposed solution, with attention to operating cases and package boundaries.
Possible output
A technical proposal evaluation or process comment register.
System and utility interfaces
Check the process connections between the gas-conditioning package, upstream equipment, downstream users and available utilities. Review relevant PFD and P&ID information and document inconsistencies that need resolution across disciplines.
Possible output
An interface clarification list and recommended next engineering actions.
