Patent number: 10052608Abstract: An apparatus for producing butadiene by way of oxidative dehydrogenation of a butene-rich feed stream includes: (a) a reactor adapted for receiving said butene-rich feed stream and converting butenes to butadiene, thereby providing a butadiene enriched product effluent stream; (b) a superheater coupled to the reactor to receive the butadiene enriched product effluent stream from the reactor as well as being configured to receive reactor feed, said superheater transferring sensible heat from the butadiene enriched product effluent stream to reactor feed and (c) a first feed-vaporizer coupled to the superheater to receive the butadiene enriched product effluent stream as it exits the superheater and to transfer sensible heat from the butadiene enriched product effluent stream to reactor feed. Also provided are (d) a second feed vaporizer; (e) a purification train; and (f) a thermal oxidizer.Type: GrantFiled: April 11, 2017Date of Patent: August 21, 2018Assignee: TPC Group LLCInventors: Liana Caciula, Joseph G.

Patent number: 9650316Abstract: Butadiene is formed by dehydrogenation of butenes which are mixed with steam and oxygen then converted to butadiene by oxidative dehydrogenation over a ferritic oxide catalyst, wherein the sensible heat in the oxidative dehydrogenation reaction product is utilized along with heat produced by thermal oxidation of low value volatile products formed to reduce energy requirements and CO2 emissions. Sensible heat is utilized at high temperature for purposes of superheating feed and at somewhat lower temperatures for purposes of vaporizing feed at sequential locations in the process.Type: GrantFiled: March 28, 2013Date of Patent: May 16, 2017Assignee: TPC GROUP LLCInventors: Liana Caciula, Joseph G. Duff, Elizabeth Ballard, Sirisha Chada, Mark J. Potter

Patent number: 8631891Abstract: A vehicular powertrain system includes an engine, an electro-mechanical transmission and an electric machine arranged in an input-split hybrid configuration. A control system for the powertrain system includes a control module signally connected to a plurality of input devices and configured to execute program code stored on a computer readable medium to control the powertrain. The program code monitors operator inputs, determines an intent to service the vehicle based upon the operator inputs, commands the electric machine to generate a net torque output of zero, and controls the engine speed correlative to an operator depression of an accelerator pedal.Type: GrantFiled: July 13, 2012Date of Patent: January 21, 2014Assignees: GM Global Technology Operations LLC, Daimler AG, Chrysler Group LLC, Bayerische Motoren Werke AktiengesellschaftInventors: Marek L. Wilmanowicz, Matthew Leonard Kaufer, Mark J. Potter, Anthony H. Heap, William R. Cawthorne, Michael J. Bolton

Patent number: 8271173Abstract: A control method for vehicular hybrid powertrain system includes monitoring operator inputs to an accelerator pedal and a transmission gear selector, and determining an operator torque request based upon the operator inputs to the accelerator pedal and the transmission gear selector. Torque output from the electric machine is commanded based upon the operator torque request. Engine output is controlled based upon the operator torque request and the commanded torque output from the electric machine. Vehicle hood position is monitored and the engine output is controlled correlative to the operator input to the accelerator pedal when the monitored position of the vehicle hood is open and the operator input to the transmission gear selector is one of a PARK and a NEUTRAL position.Type: GrantFiled: October 1, 2008Date of Patent: September 18, 2012Assignees: GM Global Technology Operations LLC, Daimler AG, Chrysler Group LLC, Bayerische Motoren Werke AktiengesellschaftInventors: Marek L.

Patent number: 5552035Abstract: A process for producing zeolite aggregates involves providing a formable paste composed of zeolite, a binder composed of an organic/metal oxide containing aluminum, a peptizing agent and water; forming the paste into an aggregate, preferably by extruding into an extrudate; curing the aggregate; hydro-thermally calcining the aggregate; and washing the hydro-thermally calcined aggregate with a washing medium, preferably followed by rinsing with a rinsing medium to remove residual washing medium from the aggregate. The washed and rinsed aggregate may then be permitted to equilibrate or is subjected to a drying procedure. Preferably, the washed and rinsed aggregate is again subjected to curing/hydro-thermal calcining.Type: GrantFiled: July 6, 1994Date of Patent: September 3, 1996Assignee: Exxon Research and Engineering CompanyInventors: Mark J.
