Repositioning of FRP flanges, part of the pipework of a cooling system

Application Repositioning of a series of flanges in the pipework of a cooling system (manufactured by others) in a combined cycle power station. These flanges were left out of place after the laying of the concrete floor, resulting in difficulty with subsequent connections. Characteristics Specifically, these four flanges of 1350mm diameter, were displaced from their […]

Aerobic biological reactor in stainless steel

Application Coating for an aerobic biological reactor in stainless steel AISI 316. The reactor was affected by corrosion caused by ferrobacteria, necessitating the application of an anticorrosive coating to protect it from the environment to which it was exposed. Characteristics The reactor was 19m in diameter and 11m in height, giving a total surface to […]

High pressure micro filtration rack

Application Manufacture of high pressure microfiltration units (MF), to be installed upstream of a reverse osmosis system (RO). These units are part of a system for eliminating sulphides from seawater in the context of a water treatment plant for the extraction of crude oil on an off-shore platform. Characteristics The filtration racks are based on […]

Piping system for desalination plant

Application Installation of piping for a treatment system based on membrane filtration, including feed and extraction systems for the racks, and filter fronts. Characteristics Huelva Plastics was responsible for the supply and prefabrication of almost all the piping in its workshops, as well as its assembly on site. The pipes installed had a wide range […]

Effluent manifold in bioethanol plant

Application Construction of a pipe system for collecting effluent in ponds. Characteristics Almost all the route of the pipes runs along a pipe rack, with the exception of a final buried section. PH Technology was responsible for the supply and installation of the system, together with all the support structures. The pipes had principal diameters […]

Hydrofluoric acid absorbers

Application This was an especially critical application due to the corrosiveness of the material to be treated, which was hydrofluoric acid at concentrations of up to 75%. The new equipment, manufactured from engineering plastics, replaced old equipment of AºCº lined with PVDF. Characteristics Two units were manufactured in consecutive years to replace the old absorbers. […]

Evaporation tower with closed cooler circuit

Application Construction of an evaporation tower with a closed cooling circuit at a chemical plant. Using the closed circuit, process water containing corrosive agents is recovered. The structural support of the tower is AºCº sheet metal, as is the support structure of the filler (in AºCº tubes). Characteristics The dimensions of the tower were 30m […]

Turnkey installation of sulphuric acid storage system

Application Installation of a storage system for dilute sulphuric acid (up to 32%), with an initial capacity of 1000 tonnes, expandable to 1500 tonnes. The system was supplied complete by PH Technology as a turnkey installation. The system consisted of two storage tanks, a pipeline connection to the plant, instrumentation and control systems, and civil […]

Duct system for removing acidic vapours

Installation of plastic ducts as part of a gas scrubbing system, specifically for the removal of acidic vapours. Characteristics The ducts were manufactured in a wide range of diameters, the main sizes being Ø2400 and Ø1000. The main Ø2400 ducts had Ø1650 inserts for connecting to the scrubbers. PH Technology was responsible for the design […]

Logistics centre for the storage and distribution of chemicals

Application The installation formed an integral part of a logistics centre for the storage and distribution of diverse chemical products. PH Technology supplied and installed the integrated plastic and stainless steel piping system for distributing chemical products around the plant. Characteristics The various circuits installed had diameters of between DN15 and DN100. In all, about […]

Square duct system for extracting gases

Installation of plastic ducts as part of a system for extracting acidic gases. Characteristics The ducts and fittings had an internal square cross section of 1600mm. As well as straight sections, various fittings such as elbows, tees, reducers and butterfly valves were also supplied. PH Technology was responsible for the design and manufacture of the […]
