Alternative technologies for using feedstock containing carbon Contemporary economic challenges: Insufficient production of oil and gas condensate. Necessity to ensure rational and effective usage of natural resources. Unstable prices for oil and motor fuel. Insufficient quality of domestically produced motor fuel. Environmental problems of the conventional usage of hard coal fuel. Depleting potential of conventional technologies for the production of motor fuel.
GIPROKOKS performs complex design and engineering activities for conventional sequence of coal blend handling for carbonization: receipt, de-freezing, preliminary crushing, stocking, proportioning of coals, supply of coke oven and by product production wastes to coal blend, finishing grinding, mixing and transportation of coal blend to coal tower
All technologies and concepts for subsequent construction work are specified taking into account the current rules and regulations: local, construction, climatic, functional, engineering, technological, fire-fighting, sanitary-hygienic, ecological, and also economic requirements of the Customer.
GIPROKOKS elaborates electrical engineering part of design documentation for major construction, reconstruction and major repair of technological facilities and power supply facilities of coke oven and by-product enterprises.
This is an engineering document which solves a set of issues related to management of territory for construction: leveling; building; reconstruction; lanscaping.
GIPROKOKS executes complex designing of coke oven plant facilities: coke oven batteries for production of blast furnace and foundry coke; ovens for production of special kinds of coke; pushing emission control systems; coke dry cooling plants; coke wet quenching complexes; coke transportation, handling, screening, uploading and storage facilities; coal towers; garages for repair of coke oven machines; hangars for erection of coke oven batteries brickwork; refractories, materials and equipment storage.
GIPROKOKS is the founder of state-of-the-art technology of coke dry cooling. The widespread tightening of environmental standards and the need to introduce energy-saving technologies of high quality coke production alongside the deterioration of coking coal feedstock base predetermine the priority of coke dry cooling for the near future.
Coke oven batteries for carbonization of stamped coal blend
GIPROKOKS has successfully implemented the technology of preliminary stamping (coal blend stamping) which is increasingly used to produce coke from coal blends with an increased content of lean-caking coals up to 65% (conventional technology provides up to 35%). The essence of the process is the compaction of coal grains during stamping. This assists to improve coking of coal during carbonization and to produce coke of high mechanical strength.
