The apparatus of the present invention serves to stun animals prior to slaughter, these being introduced with a gondola into a pit. On a sidewall of the pit is/are designed a gas module, preferably a plurality of gas modules. Each gas module comprises a gas introduction line having a multitude of pores through which an anaesthetic gas can flow laterally into the pit. The multitude of pores ensures a laminar inflow of the anaesthetic gas. The lateral laminar inflow of the anaesthetic gas avoids an increase in the stress of the animals being stunned, thus enabling humane stunning prior to slaughter. At the same time, the modular construction by means of the gas modules facilitates simple dimensioning of the gas introduction capacities required and also the construction and retrofitting of corresponding apparatuses.

Abstract

Process and method to produce ammonia with high CO2 capture rate. The invention entails production of ammonia in an efficient and innovative way with minimum carbon emissions within the production unit by use of only one CO2 removal unit and a minimum process heat exchange duties provided by heat of combustion. The proposed novel solution allows achieving a direct CO2 capture rate of >95% by the autothermal reforming based ammonia production process with one CO2 removal unit with an efficient thermal integration and a low duty fired heater ensuring minimum direct carbon emission.

Abstract

A hydrogen boil-off gas recovery method, comprises liquefying hydrogen by cooling a hydrogen feed stream in a first cryogenic cold box, further cooling the hydrogen in a second cryogenic cold box, liquefying the hydrogen in the second cryogenic cold box or downstream thereof, providing liquefied hydrogen a loading bay containing at least one hydrogen transport truck, sending boil-off gas from at least one hydrogen transport truck in the loading bay to which liquefied hydrogen has been provided to an indirect heat exchanger outside the first and second cryogenic cold boxes in order to warm the boil-off gas and mixing at least part of the warmed boil-off gas with the hydrogen feed stream upstream of the first cryogenic cold box or with hydrogen in a hydrogen refrigeration cycle used to provide refrigeration for the second cryogenic cold box as a function of the pressure of the boil-off gas.
