摘要： A method of obtaining helium from a helium-containing feed gas. Helium-containing feed gas is fed to a prepurifying unit that uses a pressure swing adsorption process to remove undesirable components from the helium-containing feed gas and obtain a prepurified feed gas. The prepurified feed gas is fed to a membrane unit connected downstream of the prepurifying unit and that has at least one membrane more readily permeable to helium than to at least one further component present in the prepurified feed gas. A pressurized low-helium retentate stream that has not passed through the membrane is fed to the prepurifying unit. The pressurized low-helium retentate is used to displace helium-rich gas from an adsorber that is to be regenerated into an already regenerated adsorber.

摘要： A method for driving a non-linear load element. On account of the non-linear interrelationship between the voltage and the current at the load element and the related non-linear dependence of the power loss on the quantities “voltage” and “current”, an adjustment of the switching speed only on the basis of the power loss in the switching element cannot be carried out with non-linear load elements without being confronted with undesirable switching losses and related electromagnetic noise fields. Therefore, the load current currently flowing in the load element is picked up in addition to the currently determined power loss in the switching element, and the switching speed of the switching element is controlled in dependence on the determined power loss and on the current picked up. The switching speed can be optimally adjusted when driving the non-linear load elements by means of PWM.
摘要翻译：一种用于驱动非线性负载元件的方法。由于负载元件上的电压和电流之间的非线性相互关系以及功率损耗对“电压”和“电流”的相关非线性依赖性，仅在其基础上调整开关速度的开关元件中的功率损耗不能用非线性负载元件执行，而不会面临不期望的开关损耗和相关的电磁噪声场。因此，除了开关元件中的当前确定的功率损耗之外，拾取负载元件中当前流动的负载电流，并且根据确定的功率损耗和当前拾取的电流来控制开关元件的开关速度。通过PWM驱动非线性负载元件时，可以最佳地调整开关速度。

摘要： A process for producing an adsorption unit is disclosed, wherein an adsorber bed of the adsorption unit is filled with a bed of an adsorbent which is selected from a multitude of adsorbents by a test method, wherein, in the test method, a particle of each adsorbent is repeatedly laden with a sorbate and regenerated again, which converts the particle to an aged particle, and a fracture property B of the aged particle of each adsorbent is determined, wherein the adsorbent for the bed is selected depending on the fracture property B determined from the multitude of adsorbents.

摘要： A method for producing urea. A methane-containing feed gas stream is reacted with oxygen by partial oxidation to form a synthesis gas stream containing hydrogen and carbon monoxide. The carbon monoxide is reacted with water in a water gas-shift reaction to form carbon dioxide and hydrogen. The synthesis gas stream is separated into a first synthesis gas substream a second synthesis gas substream. The first synthesis gas substream is subjected to pressure-swing adsorption to separate hydrogen and the second synthesis gas substream is subjected to temperature-swing adsorption to separate carbon dioxide. The separated is reacted with nitrogen to form ammonia and the ammonia is reacted with the carbon dioxide to form urea.

摘要： Disclosed is for controlling a light source by pulse width modulation of a supply voltage. The supply voltage, or a parameter dependent thereon, is measured and the pulse width is controlled as function of the measured value. The supply voltage or parameter is measured at least twice during the pulse and may be cyclically measured. The pulse width of the current or a subsequent pulse is matched to the recorded value of the supply voltage or the parameter. A total value is generated from all of the measured values and compared with a given value and the pulse width of subsequent pulses are matched as function of the difference between the total value and the given value.
