Plant for recovering hydrocarbon products from spent oils or the like

摘要

The invention relates to a plant for recovering hydrocarbon products from spent oils or the like by distillation or rectification, which plant is designed as a small, preferably transportable functional unit with a distillation vessel, which can especially be heated electrically, an upstream filter, a waste gas postcombustion, process heat exchangers and an insulation jacket around the distillation vessel and the process heat exchangers, according to Patent ... (Patent Application P 3,236,787), and is characterised in that the distillation vessel has a device for taking off process gas, which device is especially connected to a downstream compressor which in turn is connected to a gas liquefaction unit. The plant can also include a receiver for the sulphurous constituents of the spent oil, with a downstream sulphuric acid preparation unit.
