PJSC "Kаzаnorgsintez"

Work description:

Revamp of the ethylene plant of PJSC Kazanorgsintez for the purpose of operational flexibility for processing of propane feed. Maintaining of the annual production capacity of high-purity ethylene with insufficient supply of ethane feed will be achieved by using propane feed (balancing feed).

Functions of LENNIIHIMMASH Group:

• Development of design and detailed documentation, as well as documentation for the retrofit based on the basic design of Technip Company;
• Passing of the Glavgosexpertiza of Russia (stage P) and the Industrial safety expert review (documentation for the retrofit);
• Delivery of main process and auxiliary equipment.

As a result of the reconstruction, the following goals will be achieved:

• Increase in output of finished products;
• Diversification of the feed stock (increase of propane share in processing);
• Improvement of stability and safety of production facilities. By means of replacement of obsolete and worn-out equipment of the units E-100; E-200; E-500;
• Increase of production efficiency and reduction of production expenses;
• Reduction of product cost.
