Pilot Plants

• Feeding system

  Continuous and non-fluctuation system for feeding solids such as biomass, plastics, etc in constant and reproducible manner.

• Gasifying agent inlets

  Gases streams (air, O2, steam, N2…) are preheated up to 400 °C. Complete facility for steam generation is included.

• Cyclones and filter

  Two heated cyclones connected in series and a high temperature filter to remove solid particles from gas stream, reducing ash content in the final product.

• Fluidized bed reactor

  The reactor is divided into the reactor zone and freeboard zone. Homogeneous operating temperature up to 650 – 850 °C for pyrolysis and gasification, respectively. Radiant furnace (up to 1000 °C) with three heating zones to improve temperature profile
  Provision for fluidization velocity determination.

• Condensation train

  A system of SS316 shell-tube exchanger, several vessels and coalescence filters allow cooling the hot gases and obtaining tar and bio-oil in efficient manner Under request, temperature controlled implementation to obtain fractionated bio-oil.

• Electrostatic precipitator

  Recommended for pyrolysis, the electrostatic precipitator has been designed for fogging oil separation: it enables to collect liquid particles that cannot be obtained by condensation.

•  Additional liquid feeding system

  High precision pump (up to 25 ml/min) for liquid feeding. Heat traced lines or cooling provision depending on the properties of the liquid.

• Tar collection with baths as normative

  Modular sampling train based on cool traps where the tar (high molecular weight organic compounds) is collected with the help of solvents.

• Additional hopper

  Solid refill without affecting the operating pressure of the plant to increase the experiment time.

• Automatic gas sampling system

  μGC is integrated into the plant allowing online gas sample analysis and mass balance calculations.

• Scrubber

  For retention of contaminants before venting the product gas stream

• Gas meter totalizer

  For measurement of the gas quantity that has been produced. It includes temperature and pressure correction.

•  Burner

  For combustion of remaining contaminants of the product gas stream

• Gas recycle / compression system

  Outlet gas stream can be fed again into the pilot plant at atmospheric pressure through thermal mass flow controller or it can be compressed to be fed into other equipment.

The screw reactor unit allows for obtaining add-value solid from waste by means of a slow pyrolysis process. It can treat different types of feedstock under a wide range of temperature conditions. It comprises a SS310 screw driven horizontal tubular reactor housed in a multi-zone furnace, which allows operation with temperature ramps throughout all reactor length. The residence time in the reactor can be fixed from few minutes up to hours. Thanks to an independent dosing screw system, the feed rate can be modified independently from the residence time. At reactor outlet, the solid product is collected in a vessel, whereas the obtained gas leaves the vessel through the top, where a filtering element is fixed to prevent fine particles withdrawal.

Finally, the vapors are condensed to obtain liquid, and gas product is measured in a wet gas meter. A vacuum pump is used to avoid plugs in the reactor and keep the pressure in the system constant.

Fully automatic, controlled and computerized laboratory reactor for the analysis of Fluid Catalytic Cracking (FCC), using as feedstock petroleum oils or renewable sources such as bio-oil.

• Allows studying the catalyst activity and selectivity based on the ASTM D3907 method.
• Performs continuous and automatic control of up to four independent, programmed and consecutives FCC tests.
• Versatile operation modes
  • Fixed and normalized conditions based on the ASTM D3907
  • Conditions determined by the operator for each independent run and independent step during the experiment.
    • Catalyst/oil ratio as flow rate
    • Injection flow rate Injection time
    • Temperatures
  • Quasi-zero dead volume using a perfectly engineered reactor size, precise pipe lengths and distances.
  • The standard unit can be adapted to meet specific requirements with extra-equipment (mass flow controllers, simultaneous dosing pumps, special materials of construction…)

With an excellent reaction temperature control and making use of a precise syringe pump for gasoil feeding, even for a very short reaction time, this unit carries out reaction and regeneration in-situ and consecutives stages, including coke quantification. The four liquid products obtained are collected in a cooled receiver until the end of the experiments while gases can be analyzed online in a gas chromatograph.
