Petroleum, petrochemical and natural gas industries - Axial and centrifugal compressors and expander-compressors - Part 4: Expander-compressors (ISO 10439-4:2015)

This part of ISO 10439 specifies minimum requirements and gives recommendations for axial compressors,
single-shaft, and integrally geared process centrifugal compressors and expander-compressors for
special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural
gas industries. This part of ISO 10439 specifies requirements for expander-compressors, in addition to
the general requirements specified in ISO 10439-1:2015.
This scope covers only expanders and compressors on a common shaft (expander-compressor). This
scope does not apply to expanders with separate output shafts (e.g. generator drives). Hot gas expanders
over 300 °C (570 °F) are not covered in this part of ISO 10439.

Ta del standarda ISO 10439 določa minimalne zahteve in daje priporočila za aksialne kompresorje, radialne kompresorje z eno gredjo in vgrajenim gonilom ter ekspanzijske kompresorje za posebne namene, ki obdelujejo plin ali procesni zrak v petrokemični industriji ter industriji za predelavo nafte in zemeljskega plina. Ta del standarda ISO 10439 poleg splošnih zahtev, določenih v standardu ISO 10439-1:2015, določa zahteve za ekspanzijske kompresorje. Zajema le ekspanderje in kompresorje na skupni gredi (ekspanzijski kompresor). Ne zajema ekspanderjev z ločenimi izhodnimi gredmi (npr. generatorski pogoni). Ekspanderji vročega plina nad 300 °C (570 °F) niso zajeti v tem delu standarda ISO 10439.

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction

This International Standard is based on the 7th edition of the American Petroleum Institute standard API 617.

Further or differing requirements might be needed for individual applications. This International

Standard is not intended to inhibit a supplier from offering, or the purchaser from accepting, alternative

equipment or engineering solutions for the individual application. This can be particularly appropriate

where there is innovative or developing technology. Where an alternative is offered, the supplier should

identify any variations from this International Standard and provide details.

An asterisk (*) at the beginning of the paragraph of a clause or subclause indicates that either a decision

is required or further information is to be provided by the purchaser. This information is indicated on

data sheets or stated in the enquiry or purchase order (see examples in Annex A, ISO 10439-2:2015,

Annex A, ISO 10439-3:2015, Annex A).
This International Standard includes the following annexes:
— Annex A: Datasheets;
— Annex B: Vendor (Supplier) data and drawing requirements (VDDR);
— Annex C: Nomenclature;
— Annex D: Typical materials;
— Annex E: Inspector’s checklist;
— Annex F: Nozzle forces and moments;
— Annex G: Lubrication and sealing requirements.

Annex A forms a normative part of this part of ISO 10439. Annexes B to G are for information only.

In this International Standard, where practical, US customary units are included in parentheses for

Petroleum, petrochemical and natural gas industries —

Part 4:
Expander-compressors
1 Scope

This part of ISO 10439 specifies minimum requirements and gives recommendations for axial compressors,

single-shaft, and integrally geared process centrifugal compressors and expander-compressors for

special purpose applications that handle gas or process air in the petroleum, petrochemical, and natural

gas industries. This part of ISO 10439 specifies requirements for expander-compressors, in addition to

the general requirements specified in ISO 10439-1:2015.

This scope covers only expanders and compressors on a common shaft (expander-compressor). This

scope does not apply to expanders with separate output shafts (e.g. generator drives). Hot gas expanders

over 300 °C (570 °F) are not covered in this part of ISO 10439.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are

indispensable for its application. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any amendments) applies.

For the purposes of this document, the terms, abbreviated terms, and definitions given in

ISO 10439-1:2015 apply.

NOTE A cross-section showing nomenclature of an expander-compressor can be found in Annex C.

4.1 Dimensions and units

The dimensional and unit requirements shall be in accordance with ISO 10439-1:2015, 4.1.

4.2 Statutory requirements
The statutory requirements shall be in accordance with ISO 10439-1:2015, 4.2.

SIST EN ISO 10439-4:2015
ISO 10439-4:2015(E)
4.3 Unit responsibility
The unit responsibilities shall be in accordance with ISO 10439-1:2015, 4.3.
4.4 Basic design

4.4.1 The expander shall meet at least 98 % of the predicted efficiency at the certified point (see 6.3.5.1.1).

The compressor shall deliver at least 98 % of the normal head at the normal capacity. The compressor

power at the normal condition shall not be more than 106 % of that available from the expander, nor shall

it be less than 96 % of that available from the expander.

NOTE Compressor-loaded expanders achieve a power balance that determines the speed of the machine.

There is generally no speed control governor to control the speed the way other turbine-driven compressors

are controlled. If the expander power is more than expected, then the speed of the machine will be higher than

predicted. If the compressor power is more than expected, then the speed of the machine will be lower than

predicted. The above tolerances are needed to set limits beyond which hardware changes will be required to

achieve a reasonable normal speed.

4.4.2 The compressor head-capacity characteristic curve at the rated speed shall rise continuously

from the rated point to surge. The compressor shall be suitable for continuous operation at any capacity

on the predicted performance curve(s) at least 10 % greater than the predicted surge capacity shown in

the proposal.

NOTE It is common for flow to be bypassed around the compressor during normal operation.

4.5 Materials

4.5.1 Materials shall be in accordance with ISO 10439-1:2015, 4.5. Refer to Annex D for a table of

typical materials.

4.5.2 If traces of mercury have been specified, aluminium impellers shall be treated by anodizing or

other approved methods.
4.6 Casings
Casings shall be in accordance with ISO 10439-1:2015, 4.6 and 4.6.1 to 4.6.7.7.
4.6.1 Pressure-containing casings

4.6.1.1 * The maximum allowable working pressure of the casing(s) shall be at least equal to the relief

valve set pressure(s) specified by the purchaser.

4.6.1.1.1 If a relief valve set pressure is not specified, the maximum allowable working pressure of an

expander casing shall be at least 1,1 times the maximum specified inlet pressure (gauge). System pressure

protection shall be furnished by the purchaser.

4.6.1.1.2 If a relief valve set pressure is not specified, the maximum allowable working pressure of

the compressor casing of an expander-compressor shall be at least 1,25 times the maximum specified

discharge pressure (gauge). System pressure protection shall be furnished by the purchaser.
