A method for producing a stabilizer composition for a polymer, particularly a polymer containing halogen such as polyvinyl chloride, in which components for forming the stabilizer composition are mixed in an extruder and continuously discharged therefrom, in which an impact modifier is admixed. A correspondingly produced stabilizer composition and the use of a planetary roller extruder to produce a stabilizer composition.

A vaporization system and control method are provided. Liquid cryogen is provided to first ambient air vaporizer (AAV) units. When an output superheated vapor temperature is less than a threshold, the liquid cryogen is provided to second AAV units. When greater than or equal to the threshold, it is determined whether the second AAV units are defrosted. When defrosted, the liquid cryogen is provided to the second AAV units. When not defrosted, it is determined whether ice has formed on the first AAV units. When not formed, it is again determined whether the superheated vapor temperature is less than the threshold. When formed, it is determined whether a current ambient condition is favorable to defrosting the second AAV units. When not favorable, the liquid cryogen is provided to the second bank of AAV units. When favorable, it is again determined whether the superheated vapor temperature is less than the threshold.

A hydrogen engine system includes: a hydrogen engine; a cooling channel through which a liquid heat medium that cools the hydrogen engine flows; and a vaporizer, disposed in the cooling channel, through which the heat medium and liquid hydrogen flow, the vaporizer causing the heat medium to vaporize the liquid hydrogen to generate hydrogen gas.

A vaporizer, through which a liquid heat medium and liquid hydrogen flow, causing the heat medium to vaporize the liquid hydrogen, includes: a spiral tube, spirally wound, in which liquid hydrogen flows; a casing being a hollow long member housing the spiral tube thereinside, the heat medium flowing on an outer surface of the spiral tube; and a spacer being a long member disposed inside a winding inner diameter of the spiral tube.

A heat exchange system includes a cold source, a heat dissipation apparatus, a water storage tank, a heating portion, and a cooling portion. The heating portion is coupled between the cold source and the water storage tank. The cooling portion is coupled between the heat dissipation apparatus and the water storage tank. The cooling portion transmits heat of the heat dissipation apparatus to water of the water storage tank to cool the heating portion, and the heating portion transmits heat of the water of the water storage tank to the cold source to heat the cold source.

A fluid storage and supply device comprising a cryogenic reservoir for storing liquefied fluid, a withdrawing circuit comprising a first withdrawing pipe having a first upstream end connected to the upper part of the reservoir and a second downstream end intended to be connected to a user member, the first withdrawing pipe comprising a first heating heat exchanger situated outside the reservoir and a second heating heat exchanger situated inside the reservoir, the withdrawing circuit comprising a set of valve(s) configured to ensure the passage of a flow of fluid circulating from the first end towards the second end by passing through the first heat exchanger and then through the second heat exchanger or by passing solely through the first heat exchanger without passing through the second heat exchanger, characterized in that the device further comprises a system for pressurizing the reservoir comprising a pressurizing pipe separate from the withdrawing circuit and comprising two ends respectively connected to the upper and lower parts of the reservoir, a vaporizing heat exchanger and a set of valve(s) configured to allow the withdrawal of liquid from the reservoir, the heating thereof in the vaporizing heat exchanger and the reintroduction thereof into the reservoir.

The present invention provides a warmer for a gas canister, the warmer including a casing having a curved surface corresponding to a bottom of a gas canister and having a structure with an open bottom, a magnet provided on an outer portion of the casing and configured to be attachable to the bottom of the gas canister, a heat generator provided in the casing and configured to transfer heat to the gas canister, and a bottom cover coupled to the bottom of the casing in a state in which the heat generator is mounted in the casing.

A heat exchange system employed to gasify liquid natural gas (LNG) or for other required purpose includes the cold substance such as LNG, a heat dissipation apparatus, a water storage tank, a heating portion, and a cooling portion. The heating portion is coupled between the cold substance and the water storage tank. The cooling portion is coupled between the heat dissipation apparatus and the water storage tank.
