Low Grade Heat Recovery Technologies

Request Number REQ5344774
Due Date June 16, 2017
Request for Proposal Details
RFP Title
Low Grade Heat Recovery Technologies
RFP Description

NineSigma, representing a Fortune 500 global energy and chemical manufacturer, invites proposals for innovative technologies capable of recovering and re-purposing low grade heat waste generated by their crude oil refinery and petrochemical operations.

Background

Oil refining and petrochemical production can involve a variety of processes occurring at both medium (150°C to 650°C) and high (greater than 650°C) temperatures, making them suitable for a variety of commercially available waste heat recovery technologies. 

 

Conversely, there are other industrial processes that take place at lower temperatures (between 70°C and 150°C). It is for these processes that NineSigma’s client is seeking novel, scalable waste heat reclamation technologies.

 

 

 

The flowchart shows the theoretical locations for low-grade waste heat recovery technologies.

 

Currently, the overhead towers and columns responsible for the various processing streams are cooled by either air fans or chilled water pipe jacketing and the heat energy is lost. Some estimates suggest that as much as 30% of energy input is used for cooling of these areas. 

 

Depending on the production process, the temperature drop can range from as little 35°C to as much as 135°C.

 

Anticipated Project Phases or Project Plan
Phase 0 – Identification of potential supply partners

  • NineSigma’s client will select one or more of the proposed technologies for further internal review
  • To be completed by Q3 2017

Phase 1 – Industrial Evaluation

  • NineSigma’s client will, according to internal maintenance schedules, pilot one or more of the technologies in their facility to evaluate the technology for both economic and technological performance
  • Technologies evaluated over a 1-2 year period of real-world usage

Phase 2 – Full scale implementation

  • Multiple installations of the successful technology, to be completed over a period of several years

 

While NineSigma’s client is primarily interested in establishing a supply agreement with a suitable technology partner, there is potential for alternate business relationships, depending on the nature and maturity of the technology proposed.

 

Additionally, NineSigma’s client prefers approaches that are either commercially available or nearly so but will consider technologies that require limited development time to achieve the desired performance.

 

Key Success Criteria

The successful technology will:

  • Successfully and efficiently recover low grade waste heat from processes that have their own target operating temperatures, pressures and flow rates:
    • Initial operating temperatures: 70°C to 180°C 
    • Cooled operating temperatures: 30°C to 50°C
    • Operating pressures: near atmospheric pressure (e.g. 0.3 kg/cm2g) to 200 kg/cm2
    • Process flow rates: several hundreds of kilo-liter/hr
  • Integrate with existing plant infrastructure: 
    • Depending on size constraints with the site space, fit into spaces as small as a standard office desk to as large as mid-sized house 
  • Operate reliably with minimal maintenance during 3 to 4 year plant operating cycle
    • Minimal maintenance without a plant shut-down
  • Be safe, designed to global engineering safety standards

 

Possible Approaches

Possible approaches might include, but are not limited to:

  • Conversion of waste heat to one or more of the following:
    • Electricity
    • Medium pressure steam
    • High pressure steam
  • Technologies that provide fuel savings

 

 

Approaches not of interest

The following approaches are not of interest unless significant breakthroughs have occurred to provide improved reliability and cost:

  • Power Recovery Turbine (PRT) to generate electricity
  • Discharge Thermal Energy Conversion (DTEC) to generate electricity
  • Mechanical Vapor Recompression (MVR) to generate higher pressure steam from low pressure steam

 

 

Preferred Collaboration types
  • Supply Agreement
