MD&A’s San Antonio Service Center can extend the service life of gas turbine components whose OEM service limit has passed or whose configuration is no longer suitable to operate. Significant savings can be realized by opting for lower-cost repaired spares instead of new parts. Elevated temperatures take a big toll on gas turbine components. Repair […]

Mechanical Dynamics & Analysis (MD&A) experts recently performed a thermodynamic analysis to assist our client in converting their coal and natural gas plant to combined cycle operation. The customer was able to locate a gray market Gas turbine and Heat Recovery Steam Generator (HRSG). Our team modeled how each component would interact with one another, and were […]

Mechanical Dynamics and Analysis inspected and repaired an A-10 frame High-Pressure rotor.   The unit was a 3600 rpm, 90 MW combined cycle unit.  MD&A’s Turbine-Generator Repair Facility performed the incoming inspections / evaluations, repair straightening of the rotor, final inspections, as well as high speed balance. Incoming inspections and evaluation consisted of blast cleaning, NDE, visual inspections, […]

pH and CO2 measurement are central to efficient power plant cycle chemistry. Advanced process analytics instruments can provide accurate, calculated pH and CO2 determination from three simple conductivity measurements.

Appropriate and accurate pH chemical dosing into a power plant’s water cycle is essential to minimizing waste of chemicals and boiler corrosion. Precise measurement can save pH chemical dosing costs, help reduce corrosion, and maximize personnel safety.

It’s no secret that people are concerned about the security of the U.S. power grid. Cyber criminals are always looking to exploit weaknesses in systems and networks. And unless you’re looking for malicious activity, you may not even know that your networks have been breached.
Network monitoring can be used to detect unusual behavior and provide

It’s time for power and utilities to move to the cloud – here are 4 major reasons why.

A multifaceted approach to cybersecurity can help power utilities provide defense against similar attacks.

You know you need site access mats for your upcoming project. But should you rent, buy, or lease them? Making the right decision means considering many factors, including project duration, jobsite conditions, equipment, mat quality – even the potential for extreme weather. In this white paper, you will learn how to navigate the decision and choose the option that saves you time, money, and headaches. Find out the questions you must ask potential suppliers, and what happens when jobs go longer than planned.

Let’s take a look at how organizations can take the first few steps towards GDPR compliance.

Protecting the nation’s critical infrastructure is becoming much more difficult in the face of escalating cyber attacks as well as the increasing complexity of systems underlying our critical infrastructure.

Large scale projects typically involve many stakeholders, contractors and suppliers, which can lead to increased complexity and more challenging situations. Delivering such projects on time and within budget requires considerable coordination and management skills; traits that one US energy company needed in order to complete its most recent expansion project.

Most of the nation’s critical infrastructure is Internet-dependent and is the target of persistent cyber attacks. Learn what organizations can do to increase the security.

Network monitoring can provide key cybersecurity insights into an organization’s netflow activity and rapidly detect unusual behavior.

Corrosion monitoring, control and prevention is an ongoing battle in today’s power plants. Two of the strongest indicators of how well that battle is being waged is to monitor the corrosive salts of chloride and sulfate.

Every business needs to have a skills training program to one degree or another. For those involved in more complex industries, such as oil and gas or petrochemical engineering, gathering new skills as well as the experience of the older generation and passing it onto those committed to learning a new trade is an essential business practice.

Water treatment performance and determination of purity have depended on sodium measurement for nearly four decades. Monitoring cation exchange performance and the purity of power makeup water, steam and condensate has benefitted from measurement of this key parameter.

Organic contamination in cogeneration water/steam cycles is capable of causing process disruptions and catastrophic damage to expensive capital equipment. Find out how to stop it in our white paper.

A Guide to On-line Conductivity Measurement
Conductivity and resistivity are widely used parameters for water purity analysis, monitoring of reverse osmosis, cleaning procedures, control of chemical processes and in industrial wastewater. Reliable results for these varied applications depend on choosing the right conductivity/resistivity sensor.
Electrical conductivity has been measured for more than 100 years and it is

Our complimentary 48 page guide is a comprehensive reference and training tool based on decades of industry leadership in this measurement.

Pure and ultrapure water systems often require several transmitters on each water panel to monitor the various measurements needed to effectively manage water purification. To simplify this task…

In sugar and ethanol plants, steam is generated to produce power. Trace levels of silica in the pure water used to generate this steam can lead to damage to equipment such as turbines and boilers, and reduced heat transfer efficiency.

Sulzer Pump Reliability Tips
Making the right connection between impeller diameter and speed is essential when considering changes to a pumping system. Applying the pump affinity laws ensures any design changes are correctly implemented.
Sulzer offers expert assistance and also ensures that the wider mechanical systems are also sufficiently robust to accommodate changes in design.

Rapid startup is critical for modern power plants, as peaks and valleys in demand fluctuate with the increased use of alternative, renewable sources. But power plant cycling comes with risks to expensive equipment. Maintaining control of water cycle chemistry is vital to help mitigate them.  

Power plants are under pressure to accurately measure critical water quality parameters like chloride, sulfate and organics with shrinking budgets for equipment and staffing. How can they achieve this?

Falling profit margins mean there is growing pressure on power plants to do more with less. In many plants there has been a reduction in maintenance staff, and the remaining team is left trying to keep all equipment operational with a lower budget and in fewer hours. Digital sensors are a major contribution to simplifying and easing the maintenance burden.
