  56. 56. TECNOCRYO<br />ECOREL Project<br />COUNTRY: ItalyCLIENT: TECNOCRYOPROJECT: Thermal insulationprocesslinesOPERATING TEMPERATURE: -196 °C<br />The EcoRel re-liquefaction system relies on the principle of a closed nitrogen reverse Brayton cycle to produce the cold power needed to condense the BOG. The amount of cold production is proportional to the amount of boil off gas to be re-liquefied and is adapted by modifying the mass circulating in the nitrogen loop. The condensation temperature is a function of the boil off gas composition and of the selected pressure at which the condensation takes place.<br /> <br />The cycle includes 3 warm compression stages with intercoolers and after-coolers and one cryogenic expansion turbine combined in a single machine called a “compander”, a machine developed by Cryostar in 1996.<br />The cycle also includes a counter current heat exchanger and the condensing part in which the cold power is exchanged with the BOG. Operating flexibility determined the choice of splitting the condensing part into two elements: a de-superheater and a condenser. This arrangement allows the BOG loop to be started quickly, and process flexibility for different BOG compositions.<br />The BOG side consists of a two-stage compressor with inter-cooler, which relays the gas to the desuperheater and the condenser and then the return of the sub-cooled condensate to the tank.<br />v. 07-10<br />

  63. 63. Summary of Application Advantages<br />K-Flex Oil & Gas products distinguish themselves by:<br />Effectively solving installation problems for difficult applications<br />Allowing technicians easy access to their equipment for maintenance<br />Easily replacing products immediately from any<br /> K-FLEX distributor in the world <br />v. 07-10<br />
  64. 64. Cost Saving Analysis<br />Example of Potential Cost Savings<br />The following is an excerpt from a cost saving exercise conducted by an independent insulation contractor for an LNG train project1 :<br />“K-FLEX IN CLAD system for LNG application is offered as an alternative consideration because we believe it has the potential to provide:<br /><ul><li>Reduced material costs over current polyisocyanurate (PIR) or cellular glass systems
  65. 65. Reduced onsite application times over current PIR or cellular glass systems
  66. 66. Reduction in time of site man hours because of increased opportunity to pre process and fabricate the K-Flex LNG insulation system off site. (Tees, Valves, etc.)
  67. 67. Elimination of PIR dust, making a cleaner working environment and enabling a major reduction in onsite time spent vacuuming the work areas. Or in the case of cellular glass, the elimination of glass dust and smell of bad egg gas
  68. 68. Considerably reduced need for “screening” of insulation work areas because of the absence of PIR dust
  69. 69. Reduced inventory volumes because materials are flat stacked or cut from jumbo rolls. This means potential reduction in warehouse space
  70. 70. Ongoing reduced maintenance costs savings after commissioning”</li></ul>1 This cost comparison exercise was conducted by industrial contractor Giovenco Industries and AIS insulation distributors for the Gladstone LNG Project in Western Australia.

  71. 71. Significant Price Decrease<br />An Example of Potential Price Decrease on Cryogenic Equipment1:<br />**** These numbers come from an actual cost analysis for a specific LNG project. The study was not conducted by K-FLEX The above chart is used as an example to demonstrate evidence of actual cost savings with K-FLEX LNG products. Price reduction is dependant on material and labor costs in each specific region and could vary, both higher or lower, depending on location and labor. <br />1Cost reduction was calculated by industrial contractor Giovenco Industries and AIS insulation distributors for the Gladstone LNG Project in Western Australia.
