HUTNI PROJEKT Frydek-Mistek a.s. focus on cokery by-product. Our company provides complete project documentation, supply and commissioning of separate technological units, equipment and pipeline routes associated with the cleaning of raw coke oven gas and ammonia water, including production and shipment of chemical products.

We have extensive experience with the design of apparatus type tube exchangers, scrubbers, strippers, reactors, flares. Also, outside Coking chemical plants HUTNI PROJEKT Frydek-Mistek a.s. offers complete processing services from feasibility study to construction. It is mainly about the implementation of the information provided on external licensors specific solutions for the client.

Chemical technology units offer a balancing mass and heat flows (balance of existing and new technologies, optimization of technological hubs, proposals for new technological apparatus, etc.). We solve the storage of liquids and solids products, their loading and unloading, transport systems (pipelines), liquids, gases and solids. For all the above areas, we also offer supervision, start-up and commissioning.
