RFP Title


Innovative Technologies for Drying, Continuous Air Flow
RFP Description

NineSigma, representing Wärtsilä Moss, seeks innovative technologies that can remove water vapor from a continuous air flow. Technologies based on new principles, even at a research stage, are especially welcomed.


Wärtsilä provides environmentally and economically sound integrated solutions for various merchant vessels including LNG carriers.


When LNG tanks are emptied they have to be aerated to remove all combustible gases. These tanks are however very cold (-40°C) and any vapor in the air will freeze inside the tank. The current air dehumidification method Wärtsilä Moss installs on LNG carriers is based on chillers that cool the air down to 5°C to remove most of the water vapor, followed by passing the air through a desiccant tower packed with activated alumina.


Although this approach is effective it is not easy to scale and the installed capacity is not always used in an optimal way.


Thus, the client seeks novel techniques which are being developed to dehumidify air or an inert gas like N2.

Key Success Criteria

Preconditions: Continuous air flow to be dried

  • Composition:  air or an inert gas like N2
  • Gas temperature: ambient temperature is maximum 45°C
  • Gas pressure: 35-45 kPaG
  • Dew point: Same as gas temperature

Desirable drying technologies to be achieved

  • Moisture removal performance: Should bring the dew point to -45°C for the above continuous flow.
  • Scalability: Should be, in principle, able to treat large volumes of air, e.g. 20,000 Nm³/hr
  • Further desirable conditions:
    • Be easy and safe to operate
    • Require minimal maintenance
Possible Approaches

Possible Approaches

Anticipated approaches may include, but are not limited to, the following:

  • Use of a material that has high affinity with moisture in gas
  • Use of a liquid desiccant (Hygroscopic liquids)
  • Electrochemical drying techniques


Especially welcome are innovative technology based on new principles, even at a research stage.

Approaches not of Interest

The following approaches are out of the scope:

  • Technologies making use of a compressor
  • Use of cooling liquids based on chlorofluorocarbons (H-CFCs)
  • Use of toxic materials
Items to be Submitted

Proposals should include only non-confidential information and answer the following:

  • A description of the proposed solution - overview, principle and uniqueness of the technology
  • Development stage (concept level/ proved by laboratory experiment/ being considered for practical use/ commercialized)
  • Current performance
    • Inlet gas condition
      • Composition
      • Temperature
      • Pressure
      • Dew point
      • Flow rate
    • Moisture removal performance
      • Outlet gas dew point
      • Moisture capturing amount (kg-water/kg-material), in case of using a material to selectively capture water vapor
  • Conditions for sample testing (quantity of samples that can be provided, cost, time frame, contract terms and conditions, etc.)
  • Current challenges and future development plans to fulfill the requirements of the client (please elaborate on the scale-up)
  • Past achievements (additional information indicating R&D capabilities, such as research papers and patents)
  • Overview of your organization and relevant team experience
  • You may attach supplemental files to your response

The client will evaluate all responses on the following criteria:

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences

Notes on Response

Proposal shall have clear points in a concise manner. Supplemental files may be submitted in addition to the proposal.

Proposal should not include confidential information of any kind whatsoever. The client may execute non-disclosure agreements (NDA) with respondents as required for further discussions during or after the selection process by the client.

Response evaluation

The client will evaluate all responses with the following criteria.

  • Overall scientific and technical merit
  • Approach to proof of concept or performance
  • Economic potential of concept
  • Realism of the proposed plan (action items, timeline, roles, deliverables, cost estimation)
  • Potential for proprietary position
  • Respondents’ capability and related experiences

Anticipated Project Process

The client will review submitted proposals and possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select best candidates through evaluations. During the selection process, the client may execute a NDA with selected respondents, seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreements with the selected respondents and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.
