Coke, synthetic ammonia, circular economy industrial chain
Thread Content
On July 21, 2015, Huangling Mining Coal Chemical Company maintained a daily coke production of 260 tons for 9 consecutive days; the daily output of methanol and ammonia exceeded 950 tons, reaching the best level since the company’s establishment, while the daily output value surpassed 6 million yuan. The Huangling coal chemical project was completed and put into trial operation at the end of 2014. It uses 5.5-meter side-loading coal coke ovens, thereby creating a circular economic industrial chain that involves coking of refined coal – extraction of by-products from coke oven gas (coal tar, crude benzene, sulfuric acid, sulfur) – production of methanol from refined coke oven gas – and production of synthetic ammonia from methanol off-gases.
The integrated coal chemical circular economy industry chain involving the coking of refined coal – the extraction of by-products from coke oven gas (coal tar, crude benzene, sulfuric acid, sulfur) – the production of methanol from purified coke oven gas – and the production of synthetic ammonia from methanol off-gases is highly effective; the key lies in addressing the issues related to the further processing of synthetic ammonia and the recycling of water. When selecting a location, it is essential to take into account the distance to downstream ammonia processing enterprises.
A circular economy industrial chain for producing methanol from coke oven refined gas, and producing synthetic ammonia from methanol off-gas. Meaningful
It is currently a quite competitive co-production project in the industry, with support available
It is recommended to report on the current economic benefits of operations.
With the previous heat-exchange conversion furnace, it is estimated that an annual increase in synthetic ammonia production of 20,000 tons should be no problem.
