ASME PTC 47.1-2017 PDF

Full title and description

St ASME PTC 47.1-2017 — "PTC 47.1: Cryogenic Air Separation Unit of an Integrated Gasification Combined Cycle Power Plant". This Performance Test Code (PTC) provides uniform test methods and procedures for conducting performance tests of cryogenic air separation units (ASUs) that supply products to a gasification block and/or power block within an IGCC facility.

Abstract

PTC 47.1 establishes measurement methods, test conditions, data reduction and reporting requirements needed to determine ASU performance (product flows and purities, energy consumption, and related parameters) under specified, steady-state conditions. It is written to yield high-accuracy results consistent with current engineering practice and to allow meaningful comparisons between test parties. The Code explicitly excludes emissions testing, extended reliability runs, non-steady-state demonstration tests and certain liquid-production tests.

General information

• Status: Active; placed on stabilized maintenance (reaffirmed and maintained by ASME).
• Publication date: 2017 (PTC 47.1‑2017; commonly listed as 1 January 2017 in ASME catalogues).
• Publisher: The American Society of Mechanical Engineers (ASME).
• ICS / categories: Related to ICS 71 (Gases for industrial applications) — commonly cataloged under subgroups for air separation/air separation equipment and terminology (examples: 71.100 / 71.120).
• Edition / version: PTC 47.1‑2017 (designated PTC 47.1:2017, reaffirmed R2022 in ASME listings).
• Number of pages: Approximately 91 pages (common page count listed in standards catalogs).

Scope

This Code applies to cryogenic ASUs of any capacity, single-train or multi-train configurations, and is intended for testing plants in normal, steady-state operation with equipment in a new, clean and fully functional condition. Procedures cover measurement of product rates and qualities, feed and utility consumptions (air, oxygen, nitrogen, power, steam, water), and the means to correct measured results to standard reference conditions. Tests outside the scope include emissions tests, off‑design or non‑steady demonstration runs, certain liquid-production rate tests and long-duration reliability tests.

Key topics and requirements

• Definition of test objectives, test periods and required steady-state criteria for ASU performance tests.
• Instrumentation, measurement methods and calibration requirements for flows, pressures, temperatures, and composition/purity analyses.
• Procedures to determine product quantities (mass/volumetric flow) and qualities (purity, dew point) and to account for sampling and analytical uncertainties.
• Energy and utility accounting (electrical power, steam, refrigeration) and conversion to test results; correction of results to base/reference conditions.
• Data reduction, uncertainty analysis, reporting formats, and minimum required test report content to ensure repeatability and comparability.
• Limitations and explicit exclusions (e.g., emissions testing, long-term reliability tests, certain liquid-production tests).

Typical use and users

Used by plant owners/operators, commissioning and performance-test engineers, equipment manufacturers (ASU OEMs), independent test laboratories, and contracting/acceptance teams to verify ASU performance at commissioning, after major overhauls, or for contractual acceptance testing within IGCC projects. It is also used by consultants and regulators when a standardized test protocol is required.

Related standards
