  • Patent number: 8544422
    Abstract: A fired heater has two types of burners. The first burner is located in a duct which provides oxygen-containing gas to the heater to be combusted with the fuel provided by the burner. The second burner is located in the heater and provides both air and fuel for combustion. The heater may be located downstream of a gas turbine engine that cogenerates electricity and provides the oxygen-containing gas.
    Type: Grant

  • Patent number: 8176974
    Abstract: In one aspect, a heat transfer unit is provided for increasing the temperature of process fluids, such as gas-phase fluids, having a Reynolds Number (RE) of at least about 275,000 with a low overall pressure drop and without exceeding the wall temperature limits of the material used to construct the heater. The heater generally includes a heater conduit having the gas-phase fluid flowing therethrough and a heat source, such as a radiant heat source, providing an inconsistent or variable heat flux along a length of the heater conduit where the heat source has a peak heat flux greater than an average heat flux.

  • Publication number: 20080145805
    Abstract: A process is disclosed that uses fired heater having two types of burners. The first burner is located in a duct which provides oxygen-containing gas to the heater to be combusted with the fuel provided by the burner. The second burner is located in the heater and provides both air and fuel for combustion. The heater may be located downstream of a gas turbine engine that cogenerates electricity and provides the oxygen-containing gas. The second burners are operated at a low flow rate until the flow rate of oxygen-containing gas through the duct is diminished, in which case the flow rate to the second burners is increased.

  • Publication number: 20040243462
    Abstract: A method for scoring elected practices and procedures employed in relation to equipment and processes in the chemical, petrochemical, and petroleum refining industries has been developed. The method comprises identifying the current practices associated with a process or equipment used in the chemical, petrochemical, or petroleum refining industry and comparing the current practices with a set of best practices to generate the score. The best practices may comprise those selected from the group consisting of inspection practices, maintenance practices, instrumentation practices, training practices, monitoring practices, operating practices, and combinations thereof.
