Patent number: 7097758Abstract: A process to increase the non-volatile removal efficiency in a flash drum in the steam cracking system. The gas flow from the convection section is converted from mist flow to annular flow before entering the flash drum to increase the removal efficiency. The conversion of gas flow from mist flow to annular flow is accomplished by subjecting the gas flow first to at least one expander and then to bends of various degrees and force the flow to change directions at least once. The change of gas flow from mist to annular helps coalesce fine liquid droplets and thus being removed from the vapor phase.Type: GrantFiled: July 3, 2002Date of Patent: August 29, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Richard C. Stell, Jennifer L. Bancroft, Arthur R. Dinicolantonio, George Stephens

Patent number: 5092761Abstract: A method and apparatus for reducing NO.sub.x emissions from premix burners by recirculating flue gas. Flue gas is drawn from the furnace through a pipe or pipes by the aspirating effect of fuel gas and combustion air passing through a venturi portion of a burner tube. The flue gas mixes with combustion air in a primary air chamber prior to combustion to dilute the concentration of O.sub.2 in the combustion air, which lowers flame temperature and thereby reduces NO.sub.x emissions. The flue gas recirculating system may be retrofitted into existing premix burners or may be incorporated in new low NO.sub.x burners.Type: GrantFiled: November 19, 1990Date of Patent: March 3, 1992Assignee: Exxon Chemical Patents Inc.Inventor: Arthur R.
