Coke is produced from coal by coking the coal, and optionally by drying and/or preheating the coal prior to coking, and further optionally by dry cooling the coke subsequent to coking. At least the coking step is achieved in a pressure tight container which may be a transportable or tippable container. The coking step is performed in the container by conducting a gas through the container in direct or indirect heat exchange relationship with the coal and forming coke. The coking step includes a phase of lump coke formation achieved by heating the coal in a temperature range of between approximately 250.degree. and 600.degree. C. by indirect heat exchange only.

Method for the production of coke

A process of separating in multiple stages acid components in coke oven gas such as CO.sub.2, HCN and particularly H.sub.2 S by ammonia scrubbing wherein the ammonia used in scrubbing is deacidified to remove the acid components and is recirculated to the scrubbing process at least in part as substantially pure liquid ammonia.
