Design TrendsTop

Q:
What new technologies are influencing gas compressor and gas compressor system design?
24 answers
Answers:
Now a days I am not involved in operation or maintenance of gas compressors so my comments will not be of any interest. But I think that old technologies have been replaced with the latest system especially in control and emission.
~Engineering, Other, KARACHI, Pakistan
A well built diaphragm compressor will provide longer maintenance intervals, longer lasting diaphragms, more energy efficient.
~Osama A, Marketing/Sales, Warminster, PA
Technology is not influencing dry gas seals, the requirements for higher sealing pressures and larger diameters seals is.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of gas compressors and gas compressor systems?
6 answers
Answers:
Poor knowledge of seal and system designed has caused fire, explosions and release of hazardous gases. This has also resulted in major damage to compressors and added cost due to poor use of utilities.
~Glenn S, Regional Compressor Seal Specialist, Houston, TX
Serious damage to the machines due to Condensate getting into recip compressors due to the failure of Level alarm/draining of Inlet KOD has been a common occurrence in some of the sites.
~Rajagopalan M, Engineering Consultant, Chennai, Taminadu, India
The main themes usually revolve around material selection, rotor dynamics and aerodynamic specifications.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of gas compressors and gas compressor systems?
12 answers
Answers:
Selecting the least expensive compressor based on capital costs and not taking into account long term reliability, maintenance intervals, cost and quick availability of spare parts and service.
~Osama A, Marketing/Sales, Warminster, PA
Check out API specifications, they are built upon many years of compressor applications experience and result in the most robust machinery, fit for the application.
~Steven K, Business Development Manager, Bethlehem, PA
Try to select a compressor that has a variable range of applications so as the pressures deplete the compressor system will not become obsolete and unusable.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using gas compressors and gas compressor systems?
10 answers
Answers:
Review over all cost of the compressor including down-time lost due to frequent maintenance. Initial capital may be higher for diaphragm type compression versus other types, but in the long run, a good quality diaphragm compressor provides highest value if maintaining product purity is important.
~Osama A, Marketing/Sales, Warminster, PA
To lay emphasis on Proven Track record for any compressor model, while procuring machines for continuous Process Industry rather than going for a new development at the first instance.
~Rajagopalan M, Engineering Consultant, Chennai, Taminadu, India
Seek out the most knowledgeable people in the industry for specifying the machines. Make sure you have some "gray hair" on the team.
~Steven K, Business Development Manager, Bethlehem, PA
Understand what is being purchased and make sure total life cycle cost is being considered when purchasing equipment.
~Glenn S, Regional Compressor Seal Specialist, Houston, TX
Good FFED is indeed required. Ensure all relevant information is being provided.
