The project in context
Technology in its operating context.
Supply and installation of piping connections for an existing chemical process in Rybitví. The scope connected nitrogen, vent, drain and vacuum lines with valves and interfaces to existing equipment; handover took place in July 2026.
Scope of work
- Connections to an existing glass-lined kettle, column and filtration section
- Nitrogen, vent, drain and vacuum lines
- The brief specified DN 25–50 pipe branches and a 12 m DN 40 chemical hose
- Material supply, installation and agreed testing and documentation scope
Connecting existing process equipment
The piping package supported modifications to a 3,5-DNBC process. The initial brief described an existing 3.2 m³ glass-lined kettle with an agitator, a glass column and filtration equipment. EMKO’s supply concerned their piping connections and the required valves.
The technical approach distinguished the media and materials of the individual branches. The brief included stainless and steel pipework, polypropylene sections and valves with protective linings.
Nitrogen, drainage and vacuum
For the nitrogen connection, the brief specified a DN 25 branch and pressure reduction from 0.6 to 0.05 MPa, among other items. The drain section included DN 50 pipework with a DN 25 branch and a 12 m DN 40 chemical hose. These figures describe specific requirements in the project brief.
The polypropylene connection between the filter and receiver was specified as DN 50 and 10 m long, with drain and vacuum valves. Further lines served the kettle and column vents.
Piping installation and handover
The invoiced scope separates material supply, installation, and an item for inspections, tests and documentation. The handover protocol dated 24 July 2026 confirms acceptance of the equipment and its suitability for continuous operation.
The supply connected existing process units. The stated nominal sizes and lengths describe the piping package as defined in the technical brief.
Outcome
Piping connections to existing process equipment handed over with installed valves and a defined inspection scope.
