Process Engineering and Automation

Our product development cycle starts with designing and detailed engineering of a future technology and its embodiment in steel. OZNA divisions employ more than 300 professional process engineers and product design engineers who work on every custom-made solution by creating and adapting equipment to suit the special needs and requirements of a given project. Our metrological expertise and in-house 2nd grade calibration specimen allow us to meet the most demanding metrological challenges. We employ more than 100 programmers to support automated operations, remote control and future integration of all manufactured equipment with data output to the operator’s work station display.

Highlights of our approach:

  • Modular design with standardized key components to support maximum scalability and flexibility of the final solution
  • Modern industrial design of equipment with maximized ergonomics and ease of maintenance
  • Shippable modules designed for maximum operational compatibility out of the box
  • Extendability of standardized and interchangeable process lines with addition of new modules
  • Optimized metal and structural footprint with the use of combined-application equipment
  • Support of multi-level assembly of modules and distributed system of automated process control
  • Use of modern materials and multilayered anticorrosive coatings
  • Solutions allowing for dismantling and removal of process line modules for relocation to other sites for repeated use
  • Plug&Play integration of new modules into the existing operating infrastructure


Digital Simulation


Most industry standards for designing special-purpose oil and gas equipment date back to the end of the previous century. Back then it was a widely accepted industry practice to use a ready stock of standard design documentation to engineer solutions for surface equipment of oil fields. OZNA is changing that approach by making use of the latest developments in applied science achieved worldwide. We are using digital simulation methods and software tools that are currently available in the industry to design new types of equipment based on the best global practices and international engineering experience. Our focus on the business result for the Client translates into reducing the amount of metal per structure, cutting the cost of equipment ownership, or developing new technologies from scratch.

Using Modern Mathematical Models and Solution Methods:

  • Luo model for designing three-phase separators
  • Schiller-Neumann model for designing hydrocyclone oil separators
  • Multiphase mixture balance model for designing separator devices
  • Gidaspov model for designing hydrocyclone desanders
  • Reference volume method for solving partial differential equations
  • Finite-difference method with high-order approximation accuracy
OZNA Digital Simulation Administration solves applied engineering problems using a number of simulation software packages:
  • ANSYS 19.2 (including CFD, Fluent, CFX, ICEM CFD) for modelling fluid dynamics in vessels and piping, analysing stress-strain conditions of steel structures to enable structural optimization and strength prediction, and generating 3D grids of control points
  • HYSYS for modelling process lines of oil and gas treatment facilities
  • SolidWorks for preparing 3D geometry to be used in simulation of dynamic processes


Research & Development


OZNA always strives to enhance the solutions and equipment it offers. A continuous process monitoring by product development teams at every division ensures that our new products build on the global expertise while adapting applied solutions to suit the oil and gas industry of Russia. Technical conferences and technology days held by OZNA in key regions of oil and gas production across Russia are perfect venues for sharing knowledge of participating engineering experts who represent oil companies and technology leaders of the industry.

At development stage, our new solutions are rigorously shop-tested, their reported advantages being confirmed before we proceed with manufacturing the end product.

Major research and development projects currently underway:

  • Process alternatives and equipment for treatment of produced water
  • Digital products for the oil and gas industry
  • Internal equipment for separators and treatment vessels
  • Compact well metering systems
