APPARATUS FOR REGENERATING USED LUBRICATING OILS WITH HIGH OPERATING PARAMETERS Russian patent published in 2020 - IPC C10M175/02 

FIELD: technological processes.

SUBSTANCE: invention relates to regeneration of used lubricating oils and can be used, in particular, for regeneration of spent fire-resistant turbine lubricating oils at thermal power plants (TPP). Plant for regeneration of used lubricating oils contains atmospheric reservoir, outlet of which is connected by means of pipeline, on which pump and mechanical filter is installed, with inputs of at least two parallel pipelines, on each of which there is an adsorber and two shutoff devices before and after it. Besides, outlets of said parallel pipelines are connected to pipeline connected to inlet of vacuum reservoir. Note here that vacuum tank outlet is communicated via pipeline with pump and centrifugal filter arranged at atmospheric tank inlet. At that, heating tape is installed on atmospheric reservoir, vacuum tank and on all adsorbers. Heat insulation is mounted on an atmospheric reservoir, a vacuum tank, on all adsorbers and on all said pipelines.

EFFECT: maintaining the regenerated used lubricating oil operating temperature at all sections of the circuit; enabling adsorbent loading addition to adsorbers without stopping the apparatus; facilitating recirculation of recovered used lubricating oil through all plant cleaning systems; and reduction of heat losses to the environment at all sections of the circuit.
