An apparatus and method of forming a hybrid heat exchanger including a first manifold defining a first fluid inlet and a second manifold defining a second fluid inlet. A monolithic core body includes a first set of flow passages in fluid communication with the first manifold and a second set of flow passages is in communication with the second manifold. At least a portion of the first manifold or the second manifold has a tunable coefficient of thermal expansion that is less than a coefficient of thermal expansion of the structurally rigid monolithic core.

Freeze-protection systems and techniques are identified, particularly for equipment of swimming pools and spas. Included within structures subject to receiving water subject to freezing are means for accommodating expanded volumes of the water as it freezes. In this manner, the expanded volumes are less likely to cause damage to the structures themselves.

A steam exchange humidifier comprising a heat exchanger inside a tank, the tank comprising a drain and fluid inlet port for fluid in and out of the tank and a steam outlet; the heat exchanger comprising a heat exchanger array, a steam collector, a condensate collector, a steam supply port and condensate return port; the steam collector being connected to the steam supply port, and the condensate collector being connected to the condensate return port; the steam collector and the condensate collector being connected by the heat exchanger array, wherein the tank is a generally vertical body.

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.

The system and method for installing external corrosion guards of the present disclosure comprises a method of protecting tubing in tubular heat exchangers from external corrosion that includes the installation of protective collars or guards around the tube outer diameter at the tubsheet plate, anti-vibration baffle, and/or pass partition plate levels. The external corrosion guards can be installed using a ridge method, where a ridge sits on a plate level, using a mechanical expansion method, and using a mechanical rolling method.

A cooling tower having a controller installed within the cooling tower which controls the operation of pump motors, fans, dampers, valves and adjusts the speed of the fan and pump motor. The controller is placed inside a compartment which is attached to an inside surface of the cooling tower. The compartment has an inlet and an outlet such that conditioned air enters the compartment inlet and flows over the surface of the controller to either cool or heat the controller and then the conditioned air, which has flowed over the surface of the controller, exits the compartment through the compartment outlet.

A method for measuring mass changes of a heat exchanger bank (1, 2, 3) or the heat exchangers thereof of a steam boiler, which heat exchanger (4) is supported by hanger rods (7) to support beams (5,8) above the steam boiler, wherein at least one hanger rod (7) of at least one heat exchanger (4) is connected a lower measuring element (9) and an upper measuring element (10), and the changes of the measuring length (X) between the measuring elements (9, 10) is measured by a measuring instrument (15) connected between the measuring elements (9, 10) for measuring the mass changes of the heat exchanger (4). The measuring instrument (15) may be attached in between the measuring elements (9, 10) and the change in the measuring length (X) is measured by the deformation of the measuring instrument (15).
