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.

Processing contaminated water containing volatile or/and semi-volatile compounds via flash evaporation. Method and system include: superheating contaminated water (via a superheating unit), for forming superheated contaminated water having a temperature equal to or higher than a predetermined threshold temperature; flash evaporating the superheated contaminated water (via a flash evaporation unit), for forming superheated contaminated steam; and thermally oxidizing the superheated contaminated steam (via a thermal oxidation unit), so as to thermally oxidize the volatile compounds contained therein, and form thermal oxidation gas/vapor products. Optionally, further includes integrated configuration and operation of a process control/data-information processing unit, and a heat recycling unit. Results in obtaining high yields and high energy efficiencies for removal of volatile compounds from contaminated water. Particularly applicable for processing water contaminated with volatile organic compounds (VOCs) or/and semi-volatile organic compounds (SVOCs), and volatile or/and semi-volatile inorganic compounds.

Provided is a heat generating arrangement and a method for generation of heat to be used in a heat consumer. The heat generating arrangement uses combustion of aluminium and hydrogen to raise the temperature of superheated steam inside the heat generating arrangement. The heat in the superheated steam can thereafter be used in a heat consumer, such as a heat exchanger.

An integrated steam generator/steam superheater apparatus is disclosed. The disclosed apparatus can be used in a process, such as an ammonia synthesis process, to cool an ammonia converter effluent process gas and to generate superheated steam. The integrated apparatus includes a steam superheater portion wherein hot process gas is used to generate superheated steam by heat transfer to saturated steam. The apparatus also includes a steam generator portion wherein the process gas is used to generate saturated steam by heat transfer to water. Both the superheater and the steam generator are integrated into a single unit, without intervening pluming, etc., thereby saving space and equipment.
