Coke oven gas production
Koksni plin je obilen stranski produkt pretvarjanja premoga v koks. Uporablja se pri proizvodnji jekla. Vendar je zaradi nečistoč, ki jih vsebuje, neprimeren za uporabo kot gorivo ali surovina. Za znižanje stroškov, boljši donos in predelavo plina na okoljsko odgovoren način Alfa Laval zagotavlja izredno učinkovite rešitve za rafiniranje – od primarnega hlajenja plina do predelave lahkega olja.
JSW Steel, India
The performance of JSW Steel’s existing, low-cost spiral heat exchangers in its Bellary Coke plant was deteriorating due to fouling, and the units could not be opened for cleaning. The problem was solved by exchanging them for Alfa Laval spiral heat exchangers. The new heat exchangers can be opened and service personnel have full access to all channels during cleaning. In addition the new units have a 35% smaller heat transfer area resulting in low CAPEX.
Major coke producer, Poland
Having suffered from low efficiency and high maintenance costs, one of Poland’s largest coke producers substituted their existing DBO cooling system for six Alfa Laval spiral heat exchangers. The company was very satisfied with the results, and as a second step it modernized the entire benzol recovery plant with the help of engineering company Koksoprojekt. The new system comprises seven Compabloc BO steam heaters, three Compabloc BTX condensers and four spiral heat exchanger DBO/BO interchangers.
Anshan Steel, China
Anshan Steel cleans its coal tar using three Alfa Laval P2-320 decanter centrifuges with a total cleaning capacity of 8-9 tonnes per hour. The cleaned coal tar contains less than 0.3% particles (>100 μm) and the water content is reduced from 5-6% in the feed to less than 2% in the finished product.
