Reagent dosing unit (BDR)

Purpose of the reagent dosing unit Reagent dosing units (BDR) carry out automated preparation and dosed introduction of various liquid reagents into pipelines of the field oil transportation and treatment system for the implementation of in-line oil demulsification, reduction of salt deposition on the walls of product pipelines and equipment, as well as to protect pipelines and equipment from corrosion .Conditions of operation of the reagent dosing unit The reagent dosing unit is adapted to work in macroclimatic regions with a temperate and moderately cold climate (U, UHL), as well as in areas with a cold climate (CL) in accordance with the requirements of GOST 15150-69. a technological compartment (explosion hazard class B-1A) and a hardware compartment (general industrial version) on one base (frame). BDR is installed in an explosion-proof area. Composition of the block for dosing reagents In the technological compartment of the block, the following are installed: a dosing pump (electric pump dosing unit, membrane or plunger), which carries out continuous volumetric dosing of chemicals; a gear pump that fills the process tank with a chemical, pumping a chemical from an external tank into an internal one and periodic mixing of the reagent in the tank ; internal (consumable) tank of rectangular cross-section, welded, with a visual level gauge, designed for storing the chemical, equipped at the customer's request with an electric heater, a thermometer, a calibration tank for adjusting the metering pump and other additional equipment; external (technological) tank, free-flow, welded, rectangular section, with a visual level gauge, designed for storage and heating of an additional volume of chemical; piping of the injection and intake lines of dosing pumps, including, if necessary, an additional equipment; ventilation and lighting system; instrumentation for monitoring technological parameters and control stations.
