Projects that speak for us.
Every project is a test of control: of heat, of deadlines and of safety. Our engineering responds in complex shutdowns and critical constructions.
Gasification plant: Integral renewal of ducts
Integral renewal of the refractory and insulating lining in the main ducts of the gasification plant.
The components were designed and prefabricated in PROYCO's workshops under rigorous quality and thermal-resistance standards, for subsequent transport and installation by our specialised teams.
Petrochemical Complex: Sulphur recovery unit and furnaces
Intervention in the sulphur recovery unit (reactors no. 1 and no. 2), repair of gas ducts, and partial repair of linings in process furnaces PH-3 A, PH-3 A B, PH-3 A C and PH-3 A D.
Materials supplied: RAG Lite®, RAG Tix T® (tabular alumina), FireBrick RAG®, Calde Cast® and Bio Fiber Blanket RAG®. Comprehensive supply of refractories and anchors in AISI 310.
Technical shutdown at Cement Plant: Rotary kiln Ø4.6 m and DOPOL tower
Technical management, reconstruction of Ø4.6 m rotary kiln, repair of roof, side walls, clinker cooler and smoke chamber.
Intervened areas: nose ring, tire zones, precalciner and DOPOL heat-exchange tower with anti-abrasive formulations.
New construction: Biomass boiler for urban District Heating network
Design, engineering and turnkey construction of the refractory lining of a biomass boiler for an urban district heating network.
Technology employed: RAG-Tix A-ZR refractory concrete (andalusite base + zirconium reinforcement) for maximum resistance to corrosion by alkaline ashes.
Comprehensive renewal of Lime Kiln (185 t/day) for Sugar Industry
Detail engineering, manufacturing of proprietary RAG® materials, controlled technical demolition and new installation of refractory lining.
Supply of high-density bricks, ramming mixes, and on-site monitored drying and commissioning curve.
Municipal solid waste (MSW) recovery plant: Water-tube boiler
Renewal of water-tube boiler, insulation and refractory coating in areas exposed to corrosive gases and aggressive slag.
Critical areas intervened: main combustion chamber, gas headers and flue gas passes with RAG® mortars and concretes.
Biomass steam generation plant: Gasifier and cyclone
Intervention on gasifier, cyclone chamber and steam generation boiler for a biomass recovery plant.
Design, supply and installation of refractory linings optimised for extreme conditions of heterogeneous combustion and mechanical abrasion.
Steel Plant: Reheating furnace and main manifolds
Comprehensive refractory reconstruction of reheating furnace and main manifolds with continuous shifts to shorten shutdown time.
Materials applied: RAG BLOCK® precast preshaped pieces and special high-alumina thixotropic concretes.
Pellet production plant: 3D redesign and robotic demolition
Engineering, 3D redesign of thermal linings, technical robotic demolition, supply of RAG® materials, installation and controlled drying.
Optimisation of interior combustion profile and industrial dryers with lower auxiliary fuel consumption.
Grupo PROYCO's own refractory school
The EFI (PROYCO's Refractory Training School) is our internal training centre, a space dedicated to the technical training of operators, technicians and engineers. Through practical, specialised programmes, we ensure that every professional masters the installation techniques, materials and safety protocols required by high-temperature refractory engineering.
Specialised theoretical training
Classrooms equipped for learning refractory material fundamentals, thermodynamics and industrial processes.
Practice on real installations
Hands-on training with installation, demolition and drying techniques on industrial-scale equipment and mock-ups.
Safety & occupational hazard prevention
Continuous health & safety training and safety protocols for work in furnaces, boilers and high-temperature confined spaces.
