Saltigo will be showcasing its range of contract and exclusive synthesis services at Chemspec Europe. This international trade fair for fine and specialty chemicals is being held in Munich from May 31 to June 1, 2017. Saltigo specializes in the exclusive synthesis of active chemical ingredients and intermediates, and will use the fair to present its broad range of expertise targeted at customers in the agricultural, pharmaceutical and fine chemicals industries.
 
Saltigo is currently implementing a major investment program to ensure that its synthesis capacity remains at the cutting edge of technology and is sufficient for the needs of customer projects. The program has seen approximately EUR 60 million flow into the renovation and expansion of plants at the Leverkusen site. All the work is set to be completed by the end of 2017 to enable production to begin in the new facilities.
 
“Our success is based on our ability to find holistic solutions for the often complex and rapidly changing requirements of our customers,” says Dr. Torsten Derr, managing director of Saltigo, continuing that the combination of technologies and services involved in these solutions generates immediate added value for customers. “As part of this integrated business concept, we have previously continuously adapted our operations to the needs of the market. We will continue with this successful strategy so as to go on playing a leading role in exclusive synthesis in the future,” explains Derr.

The cutting edge of technology
 
Two new multi-purpose production lines in the Central Organics Pilot Plant (ZeTO) in Leverkusen are core elements of the current renovation and expansion activities. They have been specifically designed for producing large volumes of solids for the agrochemical and other industries. To this end, the production lines are being equipped with stirred-tank reactors with a capacity of up to 16 cubic meters. The ZeTO will then have more than 70 stirred vessels. A number of smaller pieces of equipment have been dismantled ahead of the expansion work for this purpose.
 
A Hastelloy Nutsche filter/dryer and a Hastelloy centrifuge/dryer combination are used to isolate the solid substances in the two lines. The high-capacity centrifuge in particular makes it easier to isolate fine-grained agrochemical active ingredients and intermediates.
 
“When it came to choosing the centrifuge and Nutsche filter, we opted for equipment made from Hastelloy, an extremely corrosion-resistant nickel-based alloy, because more and more agrochemical products contain fluorine and exhibit corrosive characteristics. While stainless steel equipment would have been significantly cheaper, it would have offered only limited resistance when manufacturing these kinds of products,” explains Dr. Boris E. Bosch, plant manager at Saltigo.
 
The ongoing investment project will also add an active container storage tank farm to the bulk storage options at Saltigo. This will ensure more efficient supplies of raw materials and solvents to production in the ZeTO and the adjacent Plant 4 (FFK plant). In addition, ISO tank containers stored there can be filled or emptied via a pipe junction connected directly to the production facilities. The plans include a reserve for further expansion of these storage capacities at a later date and for connecting more facilities.
