Abstract: A process and a system are used for production of multiple grades of ultralow aromatic solvents/chemicals having preferred boiling range, flash point and viscosity from different hydrocarbon streams. A plurality of hydrotreating steps are used to hydrotreat a plurality of hydrocarbon feedstocks in the presence of a hydrogen gas stream and a catalyst system. Further, at least one dissolved gas stripping step, at least one adsorption step, and a distillation step are included in the process. Desired iso-paraffin molecules are thereby preserved, and the undesired aromatic molecules are converted into desired naphthene molecules.

Abstract: A process for re-refining used lubricating oil (ULO), much of which is used motor oil (UMO) relies on more rapid heating, turbulent flows, higher peak temperatures, to achieve rapid thermal cracking, even including metal-bearing additives without catalysts, compared to conventional refining of crude oil and conventional recycling processing of UMO. By thermally cracking this way and scrubbing with recycled, processed liquids from the flow stream, a process readily removes metal-bearing hydrocarbons in typical lubricating oil additives. Those bonded metals consigned to heavy fraction “bottoms,” are commonly non-removable by other recycling schemes. Long chain polymers including paraffins are broken into lighter hydrocarbons with properties typical of fuels containing olefins, naphthenes, and the like. Data and analysis reveal low solids, effective metal removal, comparatively low viscosity and boiling points, and greatly reduced sulfur content in fuel and oil products resulting.

Abstract: An emergency distillation column (2) is disclosed, connected to a plant wherein a main distillation column (1) is present. Such connection occurs by means of by-pass of the pipes which supply said main column, which by-pass has stopping means of the liquid which allow the supply of said emergency column when the pressure drops downstream of the main column exceed a preset threshold value. Preferably, said stopping means are shut-off valves (28; 33; 35).
A process of use of a column (2) is furthermore described as in any one of the preceding claims wherein the pressure difference between inflow and outflow of the liquid being distilled is measured continuously and compared against a dedicated threshold.
Finally, a plant for the regeneration of waste oils is disclosed, comprising a distillation column, which furthermore comprises an emergency distillation column (2), as previously defined.

Abstract: A method is taught for maintaining a fluid within a tank. In this method an upper data acquisition device is operated which is capable of obtaining at least one characteristic of the fluid in a tank adjacent to the upper data acquisition device. A lower data acquisition device is also operated which is situated below the upper data acquisition device, capable of obtaining at least one characteristic of the fluid in the tank adjacent to the lower data acquisition device. A data analyzer is then utilized which is capable transmitting a data packet to the intermittent mixer. The method then automatically turns on the intermittent mixer from the data received from the data packet. Afterwards, the method automatically turns off the intermittent mixer from the data received from the data packet resulting in the at least one characteristic from the upper data acquisition device is within specifications of the at least one characteristic from the lower data acquisition device. In this method the intermittent mixer is capable of altering the fluid within the tank so that the at least one characteristic is consistent throughout the tank.
