 INTRODUCTION
Document Purpose & Scope
The purpose of this document is to define the recommended anti-surge valve(s) and related accessories, and
components necessary for effective operation of the anti-surge control system to avoid surge during all phases of
compressor operation. This includes valve sizing data, criteria, accessories, performance evaluation and fast stop
analysis, transmitter ranges, and flow element data. This also includes the constant values that are required to
program the anti-surge control system software.
Compressor is Dresser-Rand single body two-stage compressor configuration. Dresser-Rand is
responsible for recommendations for the components of the anti-surge system and dynamic
simulation study. Solar is only responsible for the anti surge control system and orifice sizing
requirements.
Information and Data Requirements
The table below shows the required information and data to complete and finalize the Anti-Surge System design
document.
The following documents are to be used for surge and hot bypass valve sizing requirements.
Document Title Drawing No. Rev / Date
Dresser-Rand Surge Control System Component Specification TBD
Dresser-Rand Dynamic Simulation Report TBD

General Design Notes

1. For flow measurement using orifice plates: Meter run sizing criteria shown are for units requiring accurate
performance calculations. Upstream and downstream meter-run requirements are described in AGA3 REPORT
#3.
2. The customer is responsible for keeping the recycle line free of debris that could impair valve capability.
Periodic inspections are recommended.
3. If a temporary or permanent suction line strainer is installed between the suction flow measuring element and
the compressor, the pressure drop across it must be monitored to ensure proper operation of the surge
protection system. This may be accomplished by installing a second pressure transmitter downstream of the
strainer, or delta-p transmitter across the strainer.
4. Design of the piping and the selection, and placement of instruments will significantly affect the performance of
an anti-surge control system. The benefits of a good piping & instrumentation design cannot be over
emphasized. The cost of correcting a poor design once the equipment is in operation can be astronomical.
5. All surge avoidance systems are joint venture between the compressor supplier, the controls provider, and the
piping contractor. It is imperative that communication between these entities be the highest priority for the most
efficient compressor controls design.
6. For effective anti-surge control system, all customer furnished data (e.g. suction pipe size, flow-meter data,
suction & discharge system volumes, etc) that are used on the design shall be verified and confirmed by the
customer.
