# Commission Implementing Decision of 9 October 2014 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for the refining of mineral oil and gas (notified under document C(2014) 7155) (Text with EEA relevance) (2014/738/EU), Division BAT 29: In order to reduce emissions to air from the coking production processes, BAT is to use one or a combination of the techniques given below:

Extent: E+W+S+N.I.

Primary or process-related techniques, such as:
Technique
Description
Applicability
(i)
Collection and recycling of coke fines
Systematic collection and recycling of coke fines generated during the whole coking process (drilling, handling, crushing, cooling, etc.)
Generally applicable
(ii)
Handling and storage of coke according to BAT 3
See BAT 3
Generally applicable
(iii)
Use of a closed blowdown system
Arrestment system for pressure relief from the coke drums
Generally applicable
(iv)
Recovery of gas (including the venting prior to the drum being opened to atmosphere) as a component of refinery fuel gas (RFG)
Carrying venting from the coke drum to the gas compressor to recover as RFG, rather than flaring.
For the flexicoking process, a conversion step (to convert the carbonyl sulphide (COS) into H2S) is needed prior to treating the gas from the coking unit
For existing units, the applicability of the techniques may be limited by space availability
