A polyether foam control agent including a butylene-containing polyether foam control agent useful for preparing an agrochemical formulation; a water-based agrochemical formulation containing a combination of (a) at least one butylene-containing polyether foam control agent described above, (b) at least one active ingredient, and (c) water, and a process for preparing the agrochemical formulation.

A sublimator control valve system may comprise a sublimator having an injection port, a feedwater supply, a first solenoid valve in fluid communication with the feedwater supply and the injection port of the sublimator, a first sensor in electronic communication with a first controller, the first sensor configured to measure at least one of a first pressure parameter or a first temperature parameter; and a first tangible, non-transitory memory configured to communicate with the first controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the first controller, cause the first controller to perform operations comprising receiving, by the first controller, a command signal and the first pressure parameter, and controlling, by the first controller, the first solenoid valve in response to at least one of the command signal or the first pressure parameter.

A separation system for separating a multiphase fluid into an oil fraction and at least one of a water fraction and a gas fraction includes an elongated separator vessel which includes a multiphase fluid inlet and an oil outlet located downstream of the multiphase fluid inlet, a first immersed plate heater which is positioned in the separator vessel between the multiphase fluid inlet and the oil outlet, a heating medium heater which is located externally of the separator vessel and is fluidly connected to the first immersed plate heater, a second immersed plate heater which is positioned in the separator vessel between the multiphase fluid inlet and the oil outlet and which includes an inlet and an outlet, and an oil discharge line which is connected between the oil outlet and the inlet of the second immersed plate heater. In operation, a heating fluid which is heated in the heating medium heater is circulated through the first immersed plate heater to heat the multiphase fluid, and the oil fraction discharged from the oil outlet is circulated through the second immersed plate heater to heat the multiphase fluid.

Defoamer compositions which act rapidly and over an extended period of time employ organopolysiloxanes having alkylene linking groups bridging siloxy groups, a filler, a silicone resin, and phosphoric acid.
