By regulating the heating power of the heater (11) and/or the pressure in the system, the loading of the cooler (6) is controlled as a function of the difference in temperatures (X).Type: ApplicationFiled: August 29, 2009Publication date: August 11, 2011Applicant: IKA-WERKE GMBH & CO.

Publication number: 20110180381Abstract: A method and an apparatus based on a reactor vessel (201) that is brought to a predetermined vacuum degree, in particular said vacuum degree set between 2 and 6 absolute millibar, an to a high temperature. A waste material is continuously introduced in the vessel (202), in particular a solid waste material (5) is introduced in such a way that a vacuum loss from the vessel (201) is prevented. Owing to the high temperature, waste material (5) forms a plasma that undergoes a molecular rearrangement, which gives origin to a substantially liquid residue that is collected in a bottom portion (204) of reactor (201), and to a gas (11). The gas (11), which mainly comprises carbon monoxide, hydrogen, carbon dioxide and steam, i.e. a typical syngas composition, is continuously taken away from the vessel (201) through a duct (12), and is sent to subsequent treatments to obtain a gas fuel that can be burnt by devices such as a gas turbine, a motor or a boiler.Type: ApplicationFiled: August 10, 2009Publication date: July 28, 2011Applicant: RE.CO 2 S.R.L.Inventors: Mario Fabbri, Enrico Sonno

Patent number: 7966149Abstract: Methods and systems to detect transient operations from abnormal operations, and to detect abnormal operations in a coker heater, include collecting on-line process data. The collected on-line process data is generated from a plurality of process variables of the process, or coker heater. A first representation of the operation of the process, or coker heater, is generated based on a first set of the collected on-line process data generated from a first set of the process variables. The first representation is adapted to be executed to generate a first result. A second representation of the operation of the process, or coker heater, is generated based on the first result and based on a second set of the collected on-line process data generated from a second set of the process variables. The second representation is adapted to be executed to generate a prediction of data generated from the second set of the process variables.Type: GrantFiled: September 28, 2007Date of Patent: June 21, 2011Assignee: Fisher-Rosemount Systems, Inc.Inventors: Nikola Samardzija, Ahmad A.

Patent number: 7935226Abstract: A method to remove coke from a coker drum is disclosed. The method includes the steps of impinging fluid from a fluid jet on the inside surface of the coker and then determining the vibration signal of the coker drum. The signal is then transformed to determine the amplitude versus frequency by a Fourier Transform of the vibration signal. The amplitude change of the vibration signal as it goes through a maximum, determines when the coke layer has been cut. The fluid jet is lowered into a new layer of coke.Type: GrantFiled: August 20, 2008Date of Patent: May 3, 2011Assignee: ExxonMobil Research and Engineering CompanyInventors: Limin Song, Mark M.

Publication number: 20100300864Abstract: A method for the reduction of mercury emissions from an industrial plant that utilizes a cement or minerals kiln that has a high level of mercury emissions during specific operating conditions. The invention reduces a large spike in mercury emissions typically seen in cement kiln systems when the in-line raw mill is shut-down and all preheater gases are vented to the stack directly. The invention diverts the preheater gases to a cooling device that functions as an adsorption reactor to provide mercury absorption during periods when the raw mill is not in operation.Type: ApplicationFiled: May 28, 2009Publication date: December 2, 2010Inventors: Ove Lars Jepsen, Peter T.
