Coke production

HUTNI PROJEKT Frydek-Mistek a.s. designs and supply all equipment associated with the production of coke. Coke is produced in the coke oven batteries. In terms of the type coke oven batteries we offer classic coke oven batteries (top and stamp charged) and also Heat (Non) Recovery batteries.

All types of batteries are designed with the necessary machinery (anchoring, panelling, doors, heating fittings, changing facilities, a suction device) and service machines. Of course there is a device for dust removal from coke and other features and innovations that serve to reduce the impact of operations on the environment (BAT limits).

With the coke are also related other service businesses that HUTNI PROJEKT Frydek-Mistek a.s. supplies and design. These unites are:

  • the coal charge preparation – Thawing, coal storage (outdoor and indoor), grinding, mixing and transport of coal charge on the coal tower and so on.
  • Coke quenching – quenching tower and settling sump
  • Coke Service – transport and sorting coke, grinding and drying of coke dust etc.

Pilot coke ovens

A separate chapter in this sector are Pilot coke ovens, which are used for determining the properties (especially invasive pressures) of coal. HUTNI PROJEKT Frydek-Mistek a.s. supply turnkey projects of various types of Pilot ovens according to customer requirements. Each oven is designed and implemented as a unique device.

Coke batteries

HUTNÍ PROJEKT Frýdek-Místek is able to prepare different types of coke oven batteries and pilot coking furnace in relation to the dimensions of the chamber and method of heat tracing or ducts. In the past we addressed these types of batteries:

  • Classic coke oven batteries:

COBS5-HP Top with a charge operation, chamber 5.0m high

COBS7-HP large-spaced with Top-charge operation, chamber 7.1 meters high

COBP-HP with stamp charge operation, chamber 3.6m high (0.44 m width of the chamber)

COBP2-HP with stamp charge operation, chamber height 3.5m (0.515 m width of the chamber)

COBP5.5-HP with stamp charge operation, chamber height 5.5m

  • Batteries of Heat Recovery /Non Recovery/ types

HR battery with a height of 2.66m the chamber in the crown and a width of 2.75m the chamber with the lower flue gas including the entire energy delivery for heat recovery of flue gas to produce steam or electricity.

  • Pilot Ovens (testing ovens)

PO500-HP for approx 500 kg coal charge. Simulation of carbonisation process with oven wall pressure determination.  Gas cleaning system facilities. Stamp charge operation, simulation of density for top charge available.

PO250-HP for approx 250 kg coal charge. Simulation of carbonisation process with oven wall pressure determination.  Gas cleaning system facilities. Stamp charge operation, simulation of density for top charge available.

PO60-HP for approx 60 kg coal charge. Simulation of carbonisation process with oven wall pressure determination.  Gas cleaning system facilities. Stamp charge operation, simulation of density for top charge available.

  • Sole Heated Oven (SHO)

The SHO test furnace for measuring of expansion of coking coals. The SHO furnace is designed in a two-chamber design with electric heating of the furnace bottom.
The capacity of each chamber is 6kg of coal.
The operation of the furnace is controlled automatically and the test results are recorded in a connected industrial PC.

Catalysts RANIDO

Product description:

RCAT®-3000 is a nickel-based catalyst on high resistance magnesium oxide carrier, used for decomposition of NH3 in coke oven gas.
Utilization of the catalyst is in ammonia decomposition furnaces upstream of Claus reactors. Catalyst is produced in the shape of Raschig rings with dimensions 20x20x4 cm. As the temperature in ammonia decomposition furnace exceeds 1000 °C, we recommend using the catalyst in combination with ABSM – high purity alumina balls – to extend the catalyst lifetime.

Outlet gas from the ammonia decomposition furnace is further treated in Claus reactors, where sulphur compounds are converted to elemental sulphur. Standard catalyst for the Claus process is alumina based RCAT®-9001.
Process temperature of the Claus reactors is significantly lower than in the case of ammonia decomposition furnace (200-320 °C). Catalyst is supplied in the shape of spheres with diameter 4-6 mm together with high resistance ceramic balls CBSM protecting the catalyst and improving its lifetime.

RCAT®-9002 serves as an alternative catalyst for desulphurization of industrial gases in Claus reactors. In contrast with standard alumina-based Claus process catalyst, RCAT®-9002 contains TiO2 to promote COS/CS2 hydrolysis and to improve overall efficiency of desulphurization process. Even though this catalyst is highly porous, it shows excellent mechanical and temperature resistance. RCAT®-9002 can be used in also in combination with RCAT®-9001.

Oxygen surplus in Claus reactors often leads to a sulphatation of the catalyst. Covering of the catalyst surface with sulphates reduces catalysts activity and overall efficiency of the desulphurisation process.
Increase the catalyst resistance against sulphatation using RCAT®-9003 a RCAT®-9004.

TiO2 based catalyst RCAT®-9003 is produced in a shape of oval extrudates with diameter 3-5 mm. Apart from increased catalytic activity, RCAT®-9003 shows higher resistance against sulphatation. TiO2 based Claus catalyst can be filled in the reactors separately or together with RCAT®-9001 a RCAT®-9002.

Oxygen poisoning of the standard Claus process catalyst can be avoided by using iron promoted catalyst RCAT®-9004. Catalyst improves resistance of standard Claus catalysts. It is produced in shape of spheres with diameter 4-6 mm.

Biological Wastewater treatment

Biological waste water from coke operation are specific units combining several technological stages, which serve to pre-treatment water quality for biological stage (de-tarring, chemical cleaning, etc.), which is predominantly based on processes of nitrification and denitrification.

After the biological treatment stage followed by treated water to the required quality for discharge in a given location (discoloration, oxidation etc.). excess sludge is used in the technology of coking coal to the charge and thereby reduce the environmental burden of waste produced.

HUTNI PROJEKT Frydek-Mistek a.s. provides complete project documentation, supply of equipment and construction of and commissioning of wastewater treatment plants so that they are functional at all cases which can in chemical plants and sewage themselves occur.

With partners we can design ZLD (Zero Liquid Discharge) wastewater from coke production; since the technology is the chemical part of the coking technologies with excess water and the only possible “consumer” are cooling towers, is the quality of water treated so it can be used again.

If there is another strict decreasing of waste to “zero” the technology can be equipped with crystallizer or vaporizer.

All this is performed in regard to the local conditions in which the Site is to be realized.
