Series Stills Patents (Class 196/106)
  • Patent number: 10703980
    Abstract: It has been discovered that the efficiency of asphalt blow stills can be improved by sectionalizing the blow still with perforated plates at various heights within the blow still. The perforated plates which contain a multitude of holes act to reduce air bubble size and improve the dispersion of the air bubbles throughout the asphalt flux. This increases the total surface area per unit volume of the air bubbles and promotes a faster processing time. The perforated plates also increase the contact time between the air bubbles and the asphalt flux which further results in improved efficiency and reduced blow times. This is beneficial because faster processing times can be achieved resulting in more efficient use of equipment, higher levels of productivity, lower energy requirements, cost savings, reduce blow loss, and reduced thermal history to which the asphalt is exposed.

  • Patent number: 10017700
    Abstract: An apparatus and method are described for high-yield fast pyrolysis of biomass feedstock to produce a liquid bio-oil product. A bubbling fluidized bed reactor is provided having an integrated, rapid quench apparatus for minimizing secondary cracking reactions that can otherwise lower the yield of bio-oil. A quench stream is provided inside the reactor to minimize the residence time that the product vapors spend at high temperature where cracking can occur. The quench stream is introduced downstream of the fluidized bed but still internal to the reactor. The fluidized bed medium is constrained to the bottom of the reactor and is not cooled by the quench stream.

  • Patent number: 9550945
    Abstract: A portable, semi-portable, or permanent system for removing BS&W from crude oil at the local production or bulk storage site. A demulsifier is added to the crude as it enters a low shear pump which pumps the mixture through a plate and frame type heat exchanger where the incoming crude is preheated using outgoing heated and dehydrated crude. Then the incoming crude enters an oil-water separator where it is further heated by a secondary heater within the separator and passes through a special coalescing section. Water and basic sediment separate from the crude are discharged from the bottom of the separator. The heated dehydrated crude exits the separator, flows back through the heat exchanger where it is cooled as it preheats incoming crude, and then is pumped to clean oil storage. BS&W and flow monitors on the incoming crude and outgoing crude are used to control operation of the system.

  • Patent number: 4814044
    Abstract: In a technique for recovering hydrocarbon values from a heavy hydrocarbon-water mixture, the mixture is first delivered through a sub-assembly to remove solid particulates. Then the mixture is delivered through a series of heat exchanger--kettle arrangements in which the mixture is heated above the boiling point of water. Some of the steam formed is allowed to escape through steam removal devices in the heat exchanger. The inside of the heat exchanger includes a plurality of discrete baffles which are unconnected to the heat exchanger and which can be readily removed therefrom. Heating of the mixture continues in the kettles where the bulk of the water is boiled off the mixture. A heavy hydrocarbon oil is recovered in the liquid outlet from the last kettle. The vapors boiled off are recovered and condensed to recover a light hydrocarbon oil and quite pure water.
