A method for co-generating electricity in a process plant using feedwater, where the process plant is integrated with a thermal power generator, is provided. The method includes obtaining a pressurized stream of hot feedwater from a feedwater generation unit of the process plant; compressing the pressurized stream of hot feedwater by pumping and splitting the pressurized stream of hot feedwater to obtain a first stream of feedwater and a second stream of feedwater; routing the second stream of feedwater to the thermal power generator; cooling the second stream of feedwater against a process fluid that is used in the thermal power generator to generate a heat in the thermal power generator and to obtain a cooled second stream of feedwater; and co-generating the electricity, using the thermal power generator integrated with the process plant, using the heat.

The invention relates to a partial oxidation reactor (POX reactor) having a warm-up burner for producing synthesis gas by partial oxidation of fluid carbon-containing fuels in the presence of an oxygen-containing oxidant and to a process for startup of the partial oxidation reactor According to the invention the preheating of the partial oxidation reactor is carried out via a dedicated warm-up burner which is introduced via one of the media channels of the POX burner without any need to deinstall the entire POX burner.

Partial oxidation reactor with warm-up burner for production of synthesis gas

A safety means for protecting a plant section located on the pressure side of a jet compressor connected with a propellant system against the exceedance of an admissible pressure, comprising a controlled safety valve actuated by external energy, whose control means measures is connected with the plant section to be protected via at least one pressure tapping line, wherein the safety valve is arranged such that upon exceedance of the pressure in the protected plant section it can vent propellant from the propellant system.

Safety means against pressure exceedance

A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.
