Salt transport on our customer's premises.
| Task: | installation of a pneumatic conveyor unit to replace an existing belt conveyor | |
| Department: | process engineering | process | |
| Business: | chemical industry |
The fine salts occurring after a drying process used to be mechanically transported via a belt conveyor system into a fine salt bunker.
These salts were supposed to be optionally integrable into the coarse salt system running in parallel. In view of the long conveying distance a pneumatic conveyor system was installed for the transport. The separation of the conveyed material at the top of the bunker took place via a cyclone separator. Apart from that it was ensured that the conveying air could be integrated into the existing waste gas purification system.
Services provided by VESCON:
present-state analysis
- accompanying tests on site regarding the service life behaviour of the product mixture
- projecting and design of the pneumatic conveyor system and the cyclone separator
- checking and adjustment of the existing gas purification system
- creation of the technical sheets for all components to be supplied or modified
- layout and pipeline planning for different variants
- checking the incoming documents of the component and unit suppliers
- accompanying assembly monitoring

Salt drying on our customer's premises.
| Task: | installation of a new drying unit to increase production | |
| Department: | process engineering | process | |
| Business: | chemical industry |
In the course of a production process saline solutions occur which used to be dried for further use by being passed through several pre-drying stations of a rotating drum system.
In order to increase the throughput of the plant the rotating drum system was to be replaced by a fluid bed drying system having a three times higher throughput capacity.
The new system was supposed to be put up at the same place as the old one, so that the old unit had to be dismantled and removed first. These works were carried out during an intermediate revision phase which was tightly scheduled. The cramped conditions on site represented an additional challenge. The necessary peripheral logistics such as the product feed and discharge, the dryer air supply and venting as well as the cleaning, energies like steam pressure, compressed air etc. had to be adjusted accordingly to the higher demands.
Services provided by VESCON:
- present-state analysis
- process simulation of the new requirements for assessment of the peripheral measures
- projecting and design of the new machines, devices and units
- creation of the technical sheets for all new components to be acquired
- development of a dismantling and assembly concept
- layout planning
- scheduling
- checking the incoming documents of the component and unit suppliers
- accompanying assembly monitoring
- accompanying start-up including implementation of process optimization measures

Sulphuric acid plant on our customer's premises.
| Task: | increase of the conversion performance of a wet catalytic sulphuric acid plant | |
| Department: | process engineering | process | |
| Business: | chemical industry |
In a wet catalytic operation for producing sulphuric acid after a metallurgical process the conversion rate was supposed to be raised to such an extent that compliance with the demanded emission values for sulphuric acid was guaranteed. VESCON accomplished this goal by increasing the number of conversion stages through the installation of an additional converter unit, with the existing plant components and processes being maintained as far as possible. The integration of the new unit took place parallel to the existing one, with only a short time being allowed for the switch-over.
Services provided by VESCON:
- present-state analysis
- evaluation of the existing process data
- process simulation of the present state
- process simulations of various approaches in the planning phase
- discussion of simulation results with the plant operator
- working out details of the preferred solution (mass and energy balances, creation of flow charts, process and functional descriptions etc.)
- support in realization and start-up
- creation of the operation manual and the final documentation

Step by step towards success
| Task: | analysis and new creation of a fully automated start-up step sequencer of a chemical production plant | |
| Department: | EMSR/PLT | Process | |
| Business: | chemical industry |
In this plant our customer, one of Germany's leading chemical company, produces a basic chemical product which occurs after heating with a burner control system at a temperature of approx. 300°C and at an operating pressure of approx. 270 bar in a resulting exothermic reaction.
VESCON analysed the automatic start-up and shut-down system of this production plant and created a new step sequencer with start-up, various stop and shut-down programmes. Depending on the stop condition the sequencer can switch back to the different start-up parts or into the switch-off programme.
