The construction of new chemical plants, as well as the expansion and modernization of existing facilities, requires the correct application of theories, principles and practical experience in chemical engineering, combined with an assessment of the constraints imposed by specific conditions. Engineering is a creative innovation process.

Designing a chemical plant, especially a new technological process, from the idea stage to its practical implementation, is a complex task that requires multi-stage solutions. A comprehensive approach based on the practical experience of the engineering team makes it possible to implement each project efficiently and ensure the achievement of investors’ goals in the shortest possible time. To ensure the success of a project, it is important that all teams of engineers who work on various aspects of the project work closely together to form a single team. For this reason, the design and construction of chemical plants is usually carried out on a turnkey basis, under the terms of an EPC contract with a single general contractor.

The implementation of a new chemical production project includes the following stages:

  • Creation of the project concept.
  • Preliminary economic and market assessment.
  • Obtaining and analyzing information for making a final decision.
  • Detailed economic assessment and definition of key indicators.
  • Development of a detailed design of the future plant.
  • Management of procurement of materials and equipment.
  • Construction and installation of equipment.
  • Commissioning and testing.
  • Production control.


The need to build large factories today requires from an engineering company a wealth of experience, professional competence and modern design and construction methods. In the current realities, most clients want to get a ready-made turnkey solution, shifting to the general contractor all the risks and problems that may arise during the implementation of an investment project.

Engineering design of chemical plants, the general term “chemical plant engineering” includes all engineering aspects associated with the development of a new chemical plant, modernization or expansion of an existing plant.

During the development of each project, an engineering company must evaluate the economic parameters of new technological processes, as well as propose designs for machinery and equipment and think over the optimal layout of the plant. When designing a new plant, the engineering team must consider numerous customer requirements, existing laws and standards, environmental requirements, and market factors affecting the future plant.

Since a chemical plant is usually part of a large chemical company specializing in the production of a particular product, the project must be based on the core interests of the entire company.

When developing design documentation for a chemical plant, the engineering team must take into account the type of product being manufactured, the distance to the sources of raw materials and how they are delivered, the need for fossil fuels and electricity, and much more.

Every production process is born in a laboratory, where basic calculations are made, but the engineering design of a chemical plant goes beyond such calculations due to the need to take into account the real conditions of a large-scale process with its limitations.

The industrial production of chemicals is technologically different from the production of similar products in the laboratory, as the latter usually uses simpler but less efficient methods.

At the dawn of the chemical industry, the activities of a chemical plant differed from that of laboratories only by minor modifications or an increase in the size of the equipment used. In the 21st century, any new chemical process must go through a number of mandatory steps that will ensure the maximum efficiency of the specified process before it is put into practice.


A detailed study in the laboratory of the viability of chemical reactions before use for industrial purposes is an important step, which is aimed at finding optimal conditions and obtaining the maximum product yield.
