GMRC AND ACI SERVICES INC. COMPLETE LICENSE AGREEMENT

ACI to Introduce Tunable Side Branch Absorber to Market

The Southern Gas Association Gas Machinery Research Council (GMRC) and ACI Services Inc. (ACI) have completed a license agreement that authorizes ACI to develop and market products that incorporate GMRC’s patented tunable side branch absorber (TSBA) technology. 

The tunable side branch absorber incorporates an automatically controlled variable volume at the end of a fixed choke tube connected to a gas pipeline. It provides active (i.e., variable frequency) cancelation of fundamental acoustic pulsations in piping connected to variable speed compressor systems.

The TSBA concept is one of several new pulsation control technologies resulting from GMRC sponsored research. ACI has adapted its own patent pending pneumatically actuated variable volume clearance pocket technology for use with the TSBA. TSBA products will be available for field application in the spring of 2013.

2013 Projects

High Speed Compressor Packaging Specification and Guideline - ACI Services - COMPLETED 
ACI Services Inc. has been selected by the GMRC Project Supervisory Committee to develop a High Speed Compressor Packaging Specification and Guideline, principally for large units greater than 2000 HP. The end result will be of significant benefit to the industry, helping ensure that high-speed compressor packages are properly proposed, designed, fabricated, installed and applied with successful results that meet end user, OEM and packager expectations.

Norm Shade, President, ACI Services, is serving as the project leader for the program, assisted by other ACI staff and an extended network of associates and industry professionals. Other companies involved, either through co-funding and/or in-kind donation of service/expertise include Beta Machinery Analysis, Caterpillar, Ariel, Williams Gas Pipeline, GE Oil and Gas, Enerflex, Cameron, and Dresser-Rand. The Project Guidance team consists of 20 members experienced and knowledgeable about high-speed compressors, drivers, packages, associated systems and/or end use requirements.

The Project will be implemented in three phases. Phase 1 was completed in 2011, and Phase 2 was completed in 2012.  The final phase was completed Fall 2013.  The document is available for purchase from GMRC.  To order, please email Barbara St. Clair at admin@gmrc.org 


Solutions to Mechanical Vibration Issues - Beta Machinery Analysis Phase 2
Beta Machinery Analysis has been selected by the GMRC Project Supervisory Committee as the project lead for Solutions to Mechanical Vibration Issues. Brian Howes, Chief Engineer, Beta Machinery is leading a team of industry experts in this endeavor. High vibration is a major cause of downtime and reliability problems for reciprocating compressor packages. Many sources highlight the impact that vibration problems have on small bore piping failures, vessels, nozzles, and other components. These problems can be costly, require excessive maintenance, increase project timelines, or limit the compressor’s operating flexibility.

The project initially focuses on four areas of the compressor package that experience vibration issues - discharge bottle wedge supports, suction bottle resonance, vertical scrubber resonance, and compressor mounting using adjustable chocks. The Beta/GMRC project is intended to find solutions for these problems, which could be products to help reduce the risk of vibration problems, recommended fabrication methods, or suggested analysis techniques.
The results of the project will be valuable for compressor packagers. More effective solutions can reduce the risk and cost of vibration problems. It will also be very beneficial to end users and others involved in maintenance and compressor reliability.

In addition to Beta, the following companies are contributing to the project either through co-funding, expertise, or both: Dresser-Rand, Ariel Corporation, Cameron Compression, El Paso Pipelines and Exterran.

Predicting the HP Cost of Reciprocating Compressor Manifold - Kamal Botros, Nova Research /Transcanada and Beta

Engineering Data to Aid in Chock Selection - Josh Shaver, Atmos and Clint Lingel, Ariel

PAN (Pulsation Attenuation Network) - Glen Chatfield, Optimum

REPORTS

Guideline for Gas Turbine Air Filtration Systems
This guideline summarizes the current technology and considerations for gas turbine inlet filtration systems. This document provides detailed information related to the consequences of poor inlet filtration, characteristics of air filters which are commercially available, review of different environments where a gas turbine can be installed, how to compare filtration system options based on life cycle cost analysis, which operation and maintenance practices should be performed and how filters are tested and classified.

Guideline for Field Testing Reciprocating Compressor Performance
Originally published as PCRC Report 84-10, this guideline has been updated and is a suggested best practice for field testing of reciprocating compressors. It applies to a typical reciprocating compressor or compressor package.

Application Guideline for Electric Motor Drive Equipment for Natural Gas Compression
This guideline addresses the need for practical guidance on electric motor drives for gas compressors. The guideline is directed to issues which are not addressed in detail by the existing IEEE electric motor standards or API compressor standards. The guideline is intended to educate the users of gas compression equipment who need to know how to specify the electric motor drive system and assure that the system design can support the power and speed range for the application.

Systems Mounting Guidelines for Separable Reciprocating Compressors in Pipeline Service
GMRC's objective was to develop a consensus best-practice guideline for the installation of pipeline reciprocating equipment. The intent is to ensure installations that are free from damaging vibrations, operate reliably with acceptable alignment over the long term and present the owner with affordable life cycle costs. The need for these guidelines was driven by a number of problem installations. The GMRC recognized that it was desirable for all segments of the industry to learn from such problems and to minimize or avoid them in the future.

Application Guideline for Centrifugal Compressor Surge Control Systems
This guideline provides a common reference on the required functionality of the surge control system components in different operations. This type of reference is needed because a better understanding of the surge control system design would benefit the user, system designer and compressor manufacturer alike. The guideline also provides the reader with methods of evaluating surge control system performance against recommended design criteria.

Guideline for Field Testing of Gas Turbine and Centrifugal Compressor Performance
This guideline is a suggested best practice for field testing of gas turbines and centrifugal compressors using basic rules for proper test procedures and standards.

FIELD SURVEY PROJECT  In 2012 the Project Supervisory Committee (PSC) undertook a new approach for the formulation of the GMRC’s annual research and development program. GMRC engaged consultants to assist in the formulation of the 2013 research program. A consultant team, headed by Pete Harrell, a Southwest Research Institute retiree, spent several months in an intensive effort to identify research needs throughout the industry with a special emphasis on problems and ideas originating in the field. Assisting Harrell in the effort were Randy Raymer, formerly of El Paso Corp; and Jim Bowman, Control Systems International (retired)..
