  • Patent number: 10378888
    Abstract: A device, for spatially measuring surfaces, includes a projector for projecting patterns into an object space, two cameras for recording pictures of a surface in the object space, and a control and evaluation unit for activating the cameras and evaluating the pictures. The projector includes a light source, a projection lens, at least one rotatably arranged pattern structure, and a drive for rotating the at least one pattern structure. The control and evaluation unit to: activate the cameras for simultaneously recording a picture at each of a plurality of successive points in time; identify corresponding points in the picture planes of the cameras, by way of evaluating a correlation function between the sequences of brightness values acquired for potentially corresponding points and maximizing a value of the correlation; and determine spatial coordinates of surface points by way of triangulation on the basis of the identified corresponding points.

  • Patent number: 10344226
    Abstract: A process for preparing olefinic products by thermal steam cracking of a first furnace feed composed of hydrocarbons in at least one first cracking furnace and of a second furnace feed composed of hydrocarbons in at least one second cracking furnace. The first furnace feed is at least partly converted into a first product stream in the first cracking furnace and the second furnace feed is at least partly converted into a second product stream in the second cracking furnace. A first pyrolysis oil is isolated from the first product stream and is at least partly treated chemically. The first pyrolysis oil is at least partly recirculated as furnace feed from downstream of the chemical treatment to the first cracking furnace. The first cracking furnace and the second cracking furnace are operated under different cracking conditions.

  • Patent number: 9919989
    Abstract: The invention describes a method for separating hydrocarbons in an installation for generating hydrocarbons from a hydrocarbon-containing charge by cleavage. The product gas of the cleavage, which contains gaseous hydrocarbons, is compressed, dried, and supplied as charge material into a separation stage (a front end C3/C4 separation). The front end C3/C4 separation comprises a C4 absorber and a depropanizer. A hydrocarbon fraction consisting of hydrocarbons having a maximum of 3 carbon atoms is obtained as a gaseous overhead product of the C4 absorber. A liquid hydrocarbon fraction consisting of hydrocarbons having at least 4 carbon atoms is obtained as a bottom product of the depropanizer. The front end C3/C4 separation comprises an additional process technological C2/C4 separation stage is arranged between the C4 absorber and the depropanizer.

  • Patent number: 9873645
    Abstract: The invention relates to a method for producing hydrocarbon products which comprises preparing a hydrocarbon stream (C4) which predominantly comprises branched and unbranched hydrocarbons each having four carbon atoms. A first and a second partial stream (i-C4, n-C4) are obtained from this stream (C4), the first partial stream (i-C4) predominantly comprising branched hydrocarbons with four carbon atoms and the second partial stream (n-C4) predominantly comprising unbranched hydrocarbons with four carbon atoms. The method further comprises the steam cracking of at least part of the first partial stream (i-C4) at a first, higher cracking severity and at least part of the second partial stream (n-C4), at a second, lower, cracking severity.

  • Patent number: 9630891
    Abstract: The invention relates to a process for converting feeds composed of hydrocarbons by thermal steamcracking to at least one olefin-containing product stream comprising at least ethylene and propylene, with at least partial conversion of the feeds in at least one first cracking furnace (1) and in at least one second cracking furnace (2). According to the invention, a fresh feed (B) is fractionated into at least one first and one second fresh feed fraction (B1, B2), and the first fresh feed fraction (B1) is conducted at least partly into the first cracking furnace (1) and the second fresh feed fraction (B2) at least partly into the second cracking furnace (2).

  • Patent number: 9181495
    Abstract: The invention relates to a process for cracking a hydrocarbon-containing feed in a cracking furnace. A plurality of heat exchangers are arranged in the convection zone of the cracking furnace to utilize the heat of flue gas formed in the radiation zone by combustion. Depending on the type and state of matter of the hydrocarbon-containing feed, flow occurs through the heat exchangers to achieve, independently of the type and state of matter of the hydrocarbon-containing feed, an exit temperature of the flue gas in the range from 80° C. to 150° C.
