CiBAS™ Technology

Simplicity & Performance:
The perfect match...

We took our class leading traditional equipment and developed
an even more perfect solution: CiBAS™

It's really simple; we believe the technology created in building CiBAS™ is helping to build a brighter future. Because of the unique way CiBAS™ operates, productivity and safety is kept to the maximum, whilst importantly ensuring waste outputs, emmissions and noise levels are kept to the minimum.

With the introduction of the CiBAS™ unit we have incorporated the benefits of concentric technology. Years of fired heater and gas turbine experience, and a wealth of knowledge & experience of the offshore industry has resulted in the production of our leading edge CiBAS Energy Recovery System. Nowhere else will you find this experience or technology; CiTECH™ introduces the unique CiBAS Energy Recovery System. Not only is CiBAS™ lightweight and compact, but it has been designed from the ground up to be an innovatively flexible package that can operate at several levels as a fully integrated factory assembled unit.

In our quest to provide you with exactly the right package for your project's demands, CiBAS™ has been developed to work as:

1. A Gas Turbine Heat Recovery Unit
2. A Gas Turbine Once Through Steam Generator
3. A Supplementary Fired Design CiBAS™ model

The extent of its benefits are far reaching and with assistance in the FEED stage, the equipment can be integrated into a design solution saving significant price, space and weight, important criteria in the early project development phase. The generic package can be installed across a range of Gas Turbines from 5 to 50 Megawatts for both Thermal Energy Recovery and Steam Generation purposes.

Whatever your process, CiBAS™ is the most compact, lightweight and cost effective way of recovering heat from your turbine exhaust.

With over 70 years experience, we have over the past 25 years delivered more than 250 world class specialised turbine heat recovery packages to the Oil and Gas Industry. Our commitment to this field has produced innovative solutions aimed at saving weight and space for Offshore designers. Innovation and the CiBAS™ concept is leading the drive for further advances in our equipment, and more importantly our client's requirements.

Simplicity - One Solution For Every Task...

As well as the multitude of functions already discussed, CiBAS™' patented design can be used for heating any fluid and controls the process temperature accurately with it's sleeve type bypass valve.

In its standard form CiBAS™ reduces a gas turbine's noise level to less than 80 dBA at 1m making it ideal for all locations without unwanted disruption.

The cold casing design allows CiBAS™ to be used in potentially explosive atmospheres associated with oil and gas platforms offshore and in petro-chemical plants onshore.

  • The benefits of this simple design include:
  • - New Developments
  • - Upgrades
  • - Retrofits
  • - Modifications
  • - Atex compliant in cold casing form
  • - Lightweight and Compact structure

For existing platform upgrades, modifications or retrofits, CiBAS™ can be loaded out and lifted on board in modules ensuring wherever possible that existing platform cranage capacity can be utilised, minimising project costs and due to its simplicity of design, ensuring rapid installation, hook up & deployment.

Performance - The Generic Family

CiTECH™ has developed CiBAS™ as a generic family of heat recovery and steam generation packages.

Helically wound, finned tube bundles are installed within the unit annulus between outer casing and internal bypass valve. Recovering heat from the full turbine flow at temperatures typically in the 400°C to 550°C range.

Benefits - The advantages of CiBAS™

  • 1. Convienience
  • Compact & fully integrated, assembled and transported as a single flange to flange unit, CiBAS™ is ready to go the moment it arrives on site. Not to mention it's lightweight build and low centre of gravity for added stability.
  • 4. Simplicity
  • Our superb design allows rapid assembly and disassembly, where needed. We provide a full post-installation maintainence service, giving you piece of mind that your unit is covered by experienced technicians with a minimum of hassle.
  • 2. Choice
  • As well as a generic family to suit every need, options include internally lined or unlined coil casing. Choose lined and you will benefit from a surface temperature of less than 67°C and reduced operating noise (less than 85 dBa) all whilst remaining ATEX compliant.
  • 5. Performance
  • The integrally mounted centre plug and bypass damper-noise attenuation is provided in bypass mode to ensure equal attenuation. CiBAS™ features an intergral fail-safe bypass valve, low level sleeve actuation, low blast profile and direct GT mounting.
  • 3. Implementation
  • With an already minimal steel support structure as standard, we can offer both vertical and axial exhaust solutions - whichever is best, making CiBAS™ suitable for any project or any installation.
  • 6. Value
  • Impeccable performance and value doesn't have to come at an inflated cost - Not only does CiBAS™ outperform others in terms of performance, but in terms of purchase, implementation and operating costs.

CiBAS versus traditional solutions

CiBAS™ versus our traditional concept - The net benefit in weight between the two solutions is in excess of 150 tonnes to the platform.

Once Through Steam Generation

CiTECH™ has used its wealth of experience in once through steam generation systems to extend its CiBAS™ range with the successful introduction of Gas Turbine OTSG packages.

Again using helically wound finned tube bundles, the equipment recovers heat from full turbine flow at temperatures in the 400°C to 570°C range. The system is designed to currently operate at pressures up to 62 Bar and super heat temperatures up to 515°C.

Steam production across the range of five package solutions ranges from 8 tonnes to 55 tonnes per hour by design. Supplementary firing the exhaust can increase these values significantly.
