Development of a chemical water treatment system for a steam generator which use in the oil field

The operation of a chemical water treatment system in the “softening” mode for the uninterrupted operation of a direct-flow coil type steam generator at an oilfield site is investigated. The main problem arising during the operation of a chemical water treatment system for a steam machine is described. A diagram of the installation of a Na-cationite filter operating as part of a water treatment unit is presented. An increase in water hardness is predicted due to the depletion of the filter material during the “softening” mode during the operation of the Na-cationite filter. A model of a coil in steam generator is presented when the water quality deteriorates due to exceeding the time of the “softening” mode. Conclusions are drawn about the adjustment of the time of the “softening” mode and the possible editing of the mode maps of the chemical water treatment system for timely switching from the main filter to the backup one in order to avoid deterioration of water quality.
