Due to the renewed interest on innov ativ e way s to conv ert the existing f uel reserv es with improv ed technologies like gasif ication, PID
Eng&Tech has worked in collaboration with important researches in the f ield of gasif ication in order to dev elop the most versatile pilot
plant existing in the market nowaday s. Its v ersatility and complete automatization, allows the user to determine optimal experimental
conditions and detecting possible operational problem in industrial gasif iers.
The most outstanding f eature of the plant is its feeding system (pending patent), which has been dev eloped by PID Eng&Tech and can
f eed up to 1.5 kg/h of diff erent solids and mixtures in an homogenous, constant and reproducible way. The design of the sy stem
prev ents hot gases f rom entering in the feeding hopper, which would ruin the experiment.
FEATURES:
Fluidized Reactor
The reactor is div ided in reactor zone and f reeboard zone.
The operating homogeneous temperature is up to 900ºC.
• Reactor zone is Ø = 3” and length = 750 mm.
Freeboard zone is Ø = 5” and length = 630 mm.
• The pressure is measured drop inside reactor, f or
f luidization speed determination.
• Particle remov al sy stem is installed to collect char and
ashes f rom bed in continuous during the experiments.
• The radiant ty pe f urnace reaches 1000ºC and has t wo
zones to improv e the unif orm temperature.
Gasifying agent inlets
• Gases streams f or f luidize the bed and gasify are
preheated up to 600ºC.
• Water is f ed by means of an alternativ e positiv e
displacement pump and v aporized up to 600ºC.
Feeding system
Continuous and non-f luctuation solid f eeding sy stem
consists of 10 litres hopper and two screw f eeders. The
solid f low is constant f rom 0.2 to 1.5 Kg/h.
• A nitrogen f low will continuously flush the dosing screw,
promoting the motion of the solids.
Cyclones
Automated and computerized laboratory-pilot plant for the study of gasification process.
• Two cy clones connected in series and heated up to
400ºC, allow remov ing solid particles f rom gas stream.
Products treatment
• A SS316 Shell and multitube heat exchanger is used
to cool the hot gases and condense tar and steam. A
f ilter allows cleaning product gas.

Scrubbers and gas meter
• As optional, a wet gas scrubber is used
to remov e contaminants, and a wet gas
meter is used to outlet stream
measurement.
Control system
• The process v ariables are controlled by
independent PID controllers.
• A Programmable Logic Controller
controls the alarms of the plant,
launching the corresponding actions in
case of failure.
• The sof tware is responsible of process
monitorization, data acquisition and
registration and experiment automation.
