Honeywell UOP selected GEA Refrigeration Technologies to supply engineered compression packages for a tail gas application at a refinery in Azerbaijan. Using GEA's screw compressor, the systems are designed for a modernization program. 

GEA's tail gas packages were chosen by Honeywell UOP as part of its pressure swing adsorption (PSA) technology to supply high quality hydrogen for the modernization of the Heydar Aliyev Oil Refinery (HAOR) in Baku, Azerbaijan. Pure hydrogen is required for the refining process. It is used to decontaminate oil and facilitate catalytic processes that produce clean-burning fuels.

According to Honeywell, PSA technology will help Azerbaijan meet growing domestic demand for transportation fuels that satisfy the Euro V standards. The modernization will enable the refinery to process 7.5 million metric tons per year of crude oil blended from local sources.

The tail gas compression units receive the tail gas from the PSA system and keep stable pressure at the PSA discharge. Received gas is compressed and then cooled down to 104°F (40°C) in the aftercooler before it is returned to the customer’s system. These units are based on an oil-flooded screw compressor, and the oil is separated from the tail gas into two oil separators in order to deliver the gas with less than 1 ppm of oil content.
