The present disclosure provides natural gas and petrochemical processing systems, including oxidative coupling of methane reactor systems that may integrate process inputs and outputs to cooperatively utilize different inputs and outputs in the production of higher hydrocarbons from natural gas and other hydrocarbon feedstocks. The present disclosure also provides apparatuses and methods for heat exchange, such as an apparatus that can perform boiling and steam super-heating in separate chambers in order to reach a target outlet temperature that is relatively constant as the apparatus becomes fouled. A system of the present disclosure may include an oxidative coupling of methane (OCM) subsystem that generates a product stream comprising compounds with two or more carbon atoms, and a dual compartment heat exchanger downstream of, and fluidically coupled to, the OCM subsystem.

Embodiments of the present disclosure include a system, method, and apparatus comprising a direct steam generator configured to generate saturated steam and combustion exhaust constituents.

This is a zero emissions power generation boiler that can be used to drive a wide range of steam turbines, from 20 MW up to 1200 MW, creating dry steam pressure ranging from 1000 psi up to 4500 psi. It creates steam by burning liquid hydrogen with liquid oxygen, completely eliminating the emission of greenhouse gases, lethal poisons, and every form of pollutant. It employs high-pressure cryogenic fuel pumps, a water cooling system, an electronic sparking system, a double-wall cylindrical boiler with a hemispherical top, and a control system that employs electronic sensors, actuators, signal conditions, microprocessors, digital interfaces, and mechanical back-up systems. It can be used in new power plants or as a replacement for current boilers in existing power plants. It has the option of working as part of a combined cycle system and can employ steam reheat systems.

A steam generation apparatus includes: a heat medium flow passage through which a heat medium flows; a primary economizer disposed in the heat medium flow passage; a secondary economizer disposed in the heat medium flow passage at an upstream side of the primary economizer with respect to a flow direction of the heat medium; a primary evaporator disposed in the heat medium flow passage at an upstream side of the secondary economizer with respect to the flow direction of the heat medium; a first flash tank for generating flash steam; a first feed water line configured to supply water heated by the primary economizer to the secondary economizer; and a second feed water line disposed so as to branch from the first feed water line and configured to supply the water heated by the primary economizer to the first flash tank.

A triphase organic matter pyrolysis system includes multiple devices cooperating with each other. The feeding device delivers organic matters into the preheating device. The preheated organic matters are delivered into the pyrolysis and carbonization reaction device. The steam generating device produces a saturated steam which is delivered into the water ion generating device which heats the saturated steam into a superheated steam which is dissociated into water ions which are delivered into the pyrolysis and carbonization reaction device. The water ions cut, dissociates and carbonizes the organic matters to form carbon residues and gas-liquid wastes. The heat energy is recycled by the heat recycle device and is delivered into the preheating device. The gas-liquid wastes are processed by the gas-liquid separation device and the gas purifying device to form gas and liquid that are harmless.
