Regular gas recovery
Thread Content
The plant has a capacity of 2.5 million tons per year for atmospheric and vacuum distillation; it is intended to recover the gas produced during atmospheric distillation. Does anyone know what proportion this gas accounts for? For a compressor used in recycling, what size is appropriate?
It doesn’t really depend on the scale of the installation; it mainly depends on the properties of the crude oil. With a processing capacity of 1,000 tons per year or 1,190 tons per hour, we obtain only 850 kg/h of non-condensable gas from the initial distillate. Generally, no compressors are used in such cases. If it’s the gas from the initial distillation stage, its proportion is around 4%. We opted for a method that involves pressurizing this gas and sending it to a light hydrocarbon recovery unit for separation, without using any compressors.
