Solutions for Power Generation Applications

Lube Oil Varnish Removal

A Hy-Pro SVR Case Study

The Problem: A plant operating multiple cycling GE 7FA turbines had experienced several fail-to-start conditions and one load trip that were attributed to lube oil varnish. The reservoir was conditioned by an electrostatic oil cleaner (EOC), however target varnish potential (QSA) values fluctuated above 50.

The Solution: With the peak summer season on the horizon, the plant installed a Hy-Pro SVR soluble varnish removal system. Within 6 weeks the QSA values stabilized below 15 and their varnish issues were eliminated.

Lube Oil Varnish Removal

Proven Lube Oil Varnish Removal and Prevention

Hy-Pro's SVR unitHy-Pro's SVR soluble varnish removal system is specifically designed to remove varnish causing contaminant while in solution, without removing critical oil additives. The ICB element technology removes the soluble oxidation by-products before they can cause damaging lube oil varnish.

  • Operate 24/7 and remove soluble varnish while the turbine is running or off-line.
  • Particulate filtration for contamination and larger insoluble varnish particles to ISO code 14/12/10 and better.
  • Top loading ICB element housing and built-in winch for easy element removal and maintenance.
  • Custom options, several electrical supply voltages and explosion proof components are available.

Water/Moisture Removal

Water/Moisture Removal Solutions

Dedicated Filtration Systems for Harmful Water and Moisture.
Hy-Pro's VAC-U-DRY Vacuum Dehydrator

Standard options include an automatic drain valve and solid state switches for reliable, 24 x 7 unattended operation.

Hy-Pro's VAC-U-DRY vacuum dehydration systems are mobile, self-contained systems for hydraulic or lube oil applications where harmful water is present.

Contaminant VAC-U-DRY Capability
Water Removes 100% of Free Water and 90%+ of Dissolved Water
Particulate ISO Cleanliness Code 13/11/8 (per ISO4406:1999)
Gases Removes 100% of Free Gases and 90%+ of Dissolved Gases
Air Removes 100% of Free Air and 90%+ of Dissolved Air

Water is one of the most common and most damaging contaminants found in a lubrication and hydraulic system.

Continuous or periodic high water levels can result in component damage and fluid degradation.

Hy-Pro's COT Turbine Oil Coalesce Skid
Turbine Oil and Fuel Coalesce Skids

Hy-Pro's COT series of coalesce systems are designed specifically for turbine oil applications. They rapidly remove free water and emulsified water to 150 PPM (0.015%) while filtering particulate to cleanliness codes of ISO 15/13/10 and better. Hy-Pro's COT coalesce systems come standard with automatic water drain circuits, solid state sensors and smart relay control panels for easy, reliable operation.

Reservoir Headspace Dehydrator

The Hy-Pro TMR reservoir head-space dehydrator eliminates the primary catalyst of acid production by removing moisture from the air mass in the reservoir. Dry air mass transfer extracts dissolved water from the fluid, extending its useful life.

EHC Filtration Solutions

Electrical Hydraulic Control (EHC) Filtration Solutions

Remove and prevent acid, lacquer, gel and sludge before they can damage your system.
The ICB Element Advantage
Hy-Pro's ICB Element

The ICB (dry Ion Charge Bonding) element from Hy-Pro and EPT has several advantages over Selexsorb and Fuller's Earth products used to remove acids in phosphate ester applications:

  • Reduce and maintain Acid Numbers (TAN) to less than 0.05 without introducing traditional acid scavenging minerals to your system.
  • Eliminate gels and deposits by removing dissolved metals (CA, Mg, Fe, Na, Si, and AL).
  • Other benefits include: rugged stainless steel construction, superior media capacity, axial flow maximizes fluid-media contact time, and more.

Hy-Pro Filtration designs and manufactures several fluid conditioning solutions for Electrical Hydraulic Control (EHC) systems that utilize phosphate ester fire resistant fluids.

ICB Element Upgrade: Eliminate and prevent EHC servo valve sticking and reduce fluid maintenance requirements by educing acids and minerals that form deposits and gels. ICB elements are also used in the SVR soluble varnish removal system (See right).

TMR Reservoir Headspace Dehydrator: Eliminate the primary catalyst of acid production by removing moisture from the air mass in the reservoir. Dry air mass transfer extracts dissolved water from the fluid, extending its useful life.

ECR (Electrostatic Contamination Removal) System: Remove large quantities of insoluble sub-micron particles. The Hy-Pro/EPT ECR system removes pre-varnish, lacquer, gel and sludge particles from less than 100 nanometers to 5 micron in size.

NSD Non-Sparking Element: Eliminate oil degradation and anti-oxidant additive depletion associated with high voltage static spark discharge. After several tests, Calpine Energy has recently authorized only Hy-Pro's NSD elements over other manufacturers.

Dynafuzz Stainless Steel Element: Provide superior filtration in systems with corrosive fluids and glass fiber media where acid can form and attack the binding agent. (Exelon Energy has mandated the use of Hy-Pro's Dynafuzz elements for many of its EHC applications.)

Lubrication System Design

Lubrication System Design

Custom Lubrication and Hydraulic System Design and Manufacturing
Lubrication System Case Study

The Problem: Sierra Pacific's Valmy Power Facility in Northern Nevada saw a need to replace 10 lubrication systems and contacted Advanced Fluid Systems. Valmy's existing lubrication systems were a maintenance nightmare as they contained different components and layouts from multiple manufacturers.

The Solution: After visiting the Valmy Power facility and meeting its team, Advanced Fluid Systems prepared a report with upgrade recommendations and a lubrication design that would meet the different lubrication requirements of each unit, while addressing maintenance concerns. We received the order and manufactured the 3 different styles of units with a similar layout, and the same components where possible, to reduce spare parts inventory and maintenance costs.

Hydraulic Lubrication Systems

Advanced Fluid Systems has been designing, manufacturing and installing custom hydraulic and pneumatic systems for almost three decades. Our philosophy has remained the same, 'learn the customer's business, build a relationship and a partnership, and provide them the highest quality solutions, products and services'. We work with you from conception through installation and support our systems anywhere you take them.

Some of our capabilities include:

  • Custom hydraulic power units, lubrication systems and filtration systems from compact 1 HP units to complex multi-pump systems for any application.
  • PLC design, in-house programming and closed loop motion profiles for accurate control and automation of position, force and velocity.
  • LCD touch screen interfaces with custom menus and real-time graphical feedback for easy setup and operation.
  • Electrical control panel and interface wiring, testing and assembly performed in-house for quality control and on-site installation accuracy.
  • Special construction materials and unique designs for hostile environments and special applications.

Air Trim Damper Controls

Air Trim Dampener and Damper Vane Controls

Reduce Maintenance Costs While Reducing NOx Emissions.

Moog's electro mechanical actuator (EMA) systems for air trim dampener and damper vane controls are a cost effective replacement for your existing system.

Moog's closed loop position control of damper vanes improves combustion control and reduces NOx without investing in aftermarket burners or Selective Catalytic Reduction Burners (SCRs).  On secondary air trim dampers, Moog's EMA systems maintain the proper fuel-to-air ratio to optimize the combustion air ratio for more efficient and consistent control of burn.  More efficient burn results in less coal consumed for the same output power resulting in reduced gas emissions into atmosphere.

Moog EMA Flapper Controls

Moog's EMA systems reduce your maintenance and operating costs:

  • Moog's electro mechanical actuators require very little maintenance compared to pneumatic systems.
  • Improved boiler efficiency and improved steam temperature control resulting in less coal burned and reduced energy consumption.
  • Better control of damper allows stability and efficiency at lower turn-down when less power is required by the grid.
  • Fewer boiler tube failures resulting from consistent control of temperature of burn.
