A different world

The production processes play a decisive role in the shaping of projects in the field of chemicals and petrochemicals. So-called global scale facilities set global standards. The challenge: chemical products don’t only have to be constantly available; they also have to be produced economically. Professional systems and methods are particularly necessary during commissioning and maintenance. Our project management guarantees safety, efficiency and sustainability – even in turnaround projects.

Conversion of crude oil distillation plant Karlsruhe

Exchange of a column and replacement of a vacuum distillation column as part of a shutdown. Planning, procurement and execution of the two major projects. The projects are executed individually.

Steamcracker Burghausen

Construction of a steam cracker for the increasing of capacity of the refinery in Burghausen as a replacement for three existing steamcrackers. The related supply and infrastructure measures are also included in the project.

Butadiene plant Wesseling

Capacity expansion and modernisation of an existing plant for the production of Butadiene. 

Butadiene plant Burghausen

Construction of a Butadiene plant (BUTAmax) and the expansion of the metathesis plant (Metathese300) to increase propylene production with the related supply and infrastructure measures at the refinery location in Burghausen.

Cuddalore refinery India

C4 (butadiene), the globally scarce resource, can be obtained as a separate raw material through the construction of a refinery extension at the existing plant.  This plant subsection construction, from extraction to intermediate storage and bottling, was an exciting management challenge due to its many internal and external interfaces. The intended inclusion of the project in an international benchmarking increased the importance of its transparency and verifiable status  recording and  management processes.


New construction of a container terminal Dormagen

The logistics company Chemion is building a second terminal in Chempark Dormagen, which will serve as a warehouse for 1,000 freight and tank containers. This will support the growth of the local chemical companies and will be the first terminal to be used for internal transports in order to reduce inner city traffic.

Chempark Leverkusen-Bürrig incineration plant

As planned by Currrenta, an additional catalyst went into operation at the end of 2018 at the hazardous waste incineration plant (SAV) in Leverkusen. It increases the company's flexibility and reduces its exhaust emissions.

Customer building in the Chempark Uerdingen, Leverkusen, Dormagen

Currenta invested around EUR 20 million in a double fiber optic network between the three Chempark sites in Dormagen, Leverkusen and Krefeld-Uerdingen. The 400-kilometer-long fiber optic cables went into operation in September 2018 and the system will be further expanded with the acquisition of BBS in May 2019.

Major pharmaceutical project Factor VIII

Factor VIII is a medication which treats blood diseases. The medicine is currently produced in Berkeley (USA)  A new production facility in Wuppertal is being built to cover global demand.   To bottle the medication, a new bottling plant is being built in Leverkusen.

Chemical Industry park Marl

The chemical industry park Marl in Marl in the Ruhr Valley is one of the biggest industrial parks in Germany.  After a fire at the CDT facility, the CDT facility was mechanically completed at the end of November 2012. The facility was operational in December as planned.

Epoxy facility Stade

One of Europe’s biggest facilities for the production of epoxy resin was built at the chemical  industry park Stade. The facility was planned, installed and commissioned on site.

Ferrochrome facility Aktobe Kazakhstan

Construction of a ferrochrome plant in Aktobe, with a planned annual production of 440,000 tonnes of Ferrochrom with high carbon content.    For direct current furnaces with a capacity of 72MW were used a melting units.

Polyol chemical facility Map Ta Phut Thailand

Realisation of a Polyol facility in Map Ta Phut (Thailand) which produces the artificial material polyol in different qualities (165 kT per year) from the locally produced propylene oxide (HPPO plant) and propylene glycol (PG plant) 

Polypropylene facility Tobolsk Russia

Construction of a propylene facility with a capacity of 500,000 tonnes per year in Tobolsk, West Siberia. The facility is integrated into SIBUR’s new propane dehydration and propylene production complex.

Ethylene glycol facility Al Jubail Saudi Arabia

One of the world’s biggest ethylene glycol production facilities was constructed at the chemical industry park Al Jubail in Saudi Arabia. The facility was planned in Germany and installed and commissioned on site.


Chemical production shutdown project Muttenz

Maintenance and inspection of a production facility for the production of pesticides in Muttenz. 

Polypropylene facility Schkopau

Modernisation of a polypropylene facility through the installation of a new process control system at the Schkopau site. 

Coal power station Wilhelmshaven

During a standstill essential parts of the steam generator were replaced in order to ensure the fastest possible recovery of the power plant.

Clinical trial manufacturing standstill

The clinical sample production in the cell culture department plans its annual standstill for maintenance and conversion work in the building and at facilities. The very narrow stand- still time frame necessitates detailed deadline and resource management so that the facility can return to production on time.

Chemical production Grenzach-Wyhlen

Grenzach is the global centre of expertise for the production of watersoluble vitamins B1, B2 and B6 as well as the fat-soluble vitamin D3. Furthermore, Grenzach produces ASCP, the fat-soluble form of vitamin C, PUFA, TEAVIGO and intermediates for the carotenoids. An operational shutdown was implemented at the Grenzach plant in August 2014. Maintenance and minor modifications were included in this operational shutdown.

Mineral oil refinery Oberrhein

Refinery – location Karlsruhe, powerstation  1 and 2. Both cogeneration power stations have a rated thermal input of 300 / 243 MW and from the use of various fuels generate steam for process heating as well as electricity. The power stations are subject to the 13th national emissions protection regulation, in accordance with this regulation, from the beginning of 2011 reduced limits for SOx, NOx and dust particles apply.  These new limits should be met by installing SCR / SNCR systems.

Hot strip rolling plant 2 Duisburg-Beeckerwerth

12 part modification standstill project for the roughing and finishing mill, the construction of the strip inspection and reconstruction of the coil discharge system, as well as upgrading the intensive cooling.
