BIAZZI solution

BIAZZI offers its BIAZZI High Performance Reactor System (BHPR) for the chemical/pharmaceutical Industry mainly for hydrogenation but also for oxidation, carbonylation, amination, phosphination and dehydrogenation. The BHPR consists of:

The Pressure vessel with a special agitation unit and with a special heat exchange system.

The Agitation unit is a combination of special elements which provide the required high gas-liquid mass transfer, shearing effects, high internal gas recirculation rate and efficient solid-liquid circulation in an optimal way.

The agitator is driven by practically maintenance-free magnetic coupling system which avoids the well-known sealing problems.

The reactor internal heat transfer elements (special vertical plates) form part of a closed circuit through which a heating medium is circulated, which can be heated or cooled. This enables a very accurate control of the temperature inside of the BHPR.

The advantages presented by the BHPR are:

Scale up

Biazzi is able to scale up laboratory hydrogenation results to any size of industrial scale plants and to give performance guarantees covering capacity, product yield and quality, and catalyst consumption. For batch processes it takes 2 weeks; for continuous processes 4 weeks. Based on the results the industrial Hydrogenation plant is designed and built.

Modular systems

BIAZZI supplies a complete know-how and engineering package as well as the related process equipment required for catalytic hydrogenation plants. BIAZZI offers from Key-Equipment (Reactor and Filter system) and Basic Engineering up to SKID mounted units.

The BHPR (batch or continuous) is used as a versatile multi-purpose or dedicated Stirred Tank Reactor System.

Cooperation: AREVA, Biazzi and Clariant further develop hydrogen storage technology

To harness the energy potential from hydrogen, three companies – – AREVA, Biazzi and Clariant – – have developed a novel hydrogen storage technology. Based on liquid organic hydrogen carrier (LOHC), a well-established and proven technology in the chemical industry, several advantages are realized in comparison to traditional, high-pressure tanks for hydrogen storage. Namely, there is no pressure to be kept constant, the safety is enhanced and the liquid can be transported more easily.

The collaboration between the companies is focused on making this system modular, with self-contained units that can be placed for example at industrial facilities for back-up power generation or to stabilize renewable energy production by storage technologies. One cubic meter of LOHC can absorb hydrogen with an energy content of up to 2000 kilowatt hours. By comparison, the same volume of hydrogen stored in a high-pressure (40 barg) tank has an energy content of about 130 kilowatt hours.

AREVA acts as the system integrator. The builder of nuclear and renewable energy production facilities has been working on storage technologies for years. Biazzi is a Swiss company that develops technologies and processes for the chemical industry and engineers and constructs chemical facilities worldwide. And, Clariant is providing catalysts for the process to fuel and defuel hydrogen. These components are the key element of the facility.

The first facility is being tested within the German pilot project “Smart Grid Solar” in the Bavarian town of Arzberg. Here, several storage technologies are being tested to balance the supply of a solar park relative to the local energy supply system. AREVA is involved in the project and has delivered an electrolyser to produce hydrogen as well as a fuel cell procured by Proton Motors to produce electricity again.

Hydrogen, typically derived from renewable energy sources, is the starting point for the process. Through hydrogenation hydrogen is added to the LOHC-liquid. LOHC combines with the hydrogen molecule and suspends it safely in the liquid. Through another step, dehydrogenation, the hydrogen can be removed from the liquid and the liquid reused over-and-over. The hydrogen can be used either in industrial processes, for mobility or to generate electricity. While being stored in the LOHC liquid, the hydrogen can easily be stored in tanks or even be transported from one site to another by tank vehicles or pipelines. Therefore, this method has the potential to offer broad opportunities for seasonal balancing of energy supply as well as for providing energy over long distances.

The ‘CAMA-GSC’ Machine

BIAZZI SA has completed its range of packaging machines for gelatinous explosives with the introduction of the CAMA-GSC, capable of packing explosives into waxed paper shells. The new design is based on the well known Niepmann Rollex, whose design and technology dates back to the early 1970s. BIAZZI’s new CAMA-GSC preserves the proven and trusted kinematics of its predecessor but realizes it using the latest technological capabilities. The result is a machine that features a fast change of cartridge caliber and length, remote supervision as well as easy maintenance.

Our family of gelatinous explosive cartridging machines now consists of the new CAMA-GSC for smaller diameters in waxed papers and the already known CAMA-GLC for larger diameters in plastic foils. Both machines perfectly interface with BIAZZI’s program of auxiliary machinery such as: bowl tilting, conveying, metal detecting, loaves extruding, cartridge weighing, printing, etc.

An eventful 2011, a year of celebration

1936 was the year Mario BIAZZI founded BIAZZI S.A., based on his novel continuous, safe process for the production of nitroglycerine. 75 years later, more than 350 industrial units have been designed and built in all continents around the world for the production of explosives, nitroaromatics and products made mainly by hydrogenation.

BIAZZI S.A. an engineering and technology company celebrated its 75th anniversary with several activities and events, culminating in the celebration ceremony taking place on September 10th 2011 with more than 130 guests. These guests were clients, partners, representatives of federal, cantonal and communal authorities, ancient collaborators, neighbors of the company, family members of the actual crew and the BIAZZI family itself.


The celebration was a success and many appreciated the information given in a company visit as well in the speeches giving information about the company and its history including targets for the future.

2011 was also a year full of business activities in all business fields of the company. In the area of explosives two units were successfully started up in Asia.

Two units were started up successfully in the field of nitro aromatics. One of those two units was started up in Europe having a capacity of more than 200.000 metric tons product produced per year (MTPY), the other unit, with an annual capacity of 160.000 MTPY was started up in Asia. Both units were built for the production of DNT (dinitrotoluene), an intermediate material for the production of Polyurethane (PU).

In the area of hydrogenation one unit was started up for the production of TDA using BIAZZI technology, with a capacity of 130’000 MTPY. TDA is a further synthesis step in PU-production. A further hydrogenation unit, for the production of 3000 MTPY of a high added value product was built in the USA as a SKID. The startup was made successfully and the process guarantees given by BIAZZI were reached to the full satisfaction of the client.

In 2011 various contracts in the fields of hydrogenation and explosives could be materialized for projects in Europe, Asia and the USA. All these projects have been started and the start ups of the units are to take place in Q3/Q4-2012. Furthermore various studies were executed leading most probably to project realizations in 2012/2013.

2011 ended with a promising pipeline giving hope for good business in the year 2012.
