Abstract

The present disclosure relates to a deaerator system comprising a feedwater supply, a heating medium supply, and a deaerator vessel. The deaerator vessel comprises an upper packing section, a lower packing section, a first space between the upper packing and the lower packing, and a second space between the upper packing and the top of the vessel, a gas outlet and a feedwater outlet. The upper packing section and the lower packing section are arranged within the deaerator vessel in fluid communication with each other, and the upper packing section is narrower than the lower packing section. The heating medium supply is arranged below the lower packing section, and the feedwater supply comprises first piping for supplying a first portion of the feedwater to the first space, and a second piping for supplying a second portion to the second space. The present disclosure further relates to methods for deaerating feedwater and to methods for servicing deaerator systems.
