Who we are

One of our most valuable advantages is a well-coordinated work of the qualified experts who make ILLA’s professional team:

Dr. Vladimir Zakoshansky

President of ILLA International, LLC. (USA)

Specialist in acid-catalytic reactions kinetics, organic and mixed solvents effect on reaction rate, aromatic hydrocarbons oxidation reactions, reactions of isoparaffin alkylation by olefins. Having graduated from Leningrad Technology Institute in 1969, he worked for scientific and production association Lenneftekhim wherefrom he received his PhD degree in 1974. From then on he has been engaged in creating world famous technologies of phenol and acetone production. His dedication and extraordinary drive, as well as his nature of a fighter and a leader made it possible to implement his revolutionary ideas at Russian plants.

In 1992 he founded a research and development company ILLA International which in several years became a leader in phenol technologies. In 1994 he was employed by General Electric Company as an independent contractor. During seven years Dr. Zakoshansky succeeded in implementing six breakthrough technologies which drastically changed the image of this large phenol producer. Having left GE, Vladimir Zakoshansky, supported by a highly professional team of researchers in ILLA International, devotes all his time to creating, developing and marketing his processes all over the world.

Dr. Zakoshansky is the author of 91 patents, including 82 on phenol production, 64 published articles, 48 of which are on phenol process improvement, kinetics and mechanism of the main and side cumene to phenol/acetone process reactions. More than 30 patents related to cumene oxidation, cumene hydroperoxide cleavage, catalytic phenol treatment and other phenol process stages are implemented in phenol production field on the basis of his inventions. Said technologies were implemented on the ground of Dr. Zakoshansky’s inventions and under his direct control at 12 commercial units, including: GE (USA), INEOS (UK), Fenoquimia (Mexico), Russia (Ufa, Omsk, Grozni, Samara, Saratov, etc.). In 2005, Vladimir Zakoshansky was acknowledged by the American Biographical Institute one of “2000 Outstanding Intellectuals of the 21st century” for creating a breakthrough phenol process.

A brilliant scientist, Vladimir Zakoshansky does not confine himself to research only. Keen on sports, music and arts, he is also a poet extremely perceptive to beauty in all its aspects – three books of his poetry were published in 2001, 2004 and 2006.

He lives in suburban Chicago, IL with his family.

Roman Rutenburg

Director of ILLA International, Ltd. (Russia)

Since 1995 he has been successfully providing for the fail-safe existence of ILLA. He graduated from Leningrad Technology Institute in 1968 and started work for one of the largest rubber-processing plants of the former USSR. An extremely gifted administrator with a unique 28 years long experience of management, Roman is also the author of about 400 implemented innovations and a co-author of 2 patents on new methods for preparation of rubber compounds. Unprecedented “Manager of unmanageable issues” in ILLA’s history.

Irina Vasilyeva

Joined ILLA in 1992. Graduating from the Chemistry Department of the Leningrad State University. She is an expert in solutions theory and phase equilibrium. Irina is an author of about 20 patents and more than 30 articles on phase equilibrium and phenol production. She received her PhD in Chemistry in 2001 and currently is at the head of R&D center in St.Petersburg engaged in development of new methods for producing phenol on commercial scale. Area of expertise: analytical and separation methods comprising fractionation, extraction and adsorption. Member of Board of Directors.

Tatyana Tyvina

Left scientific and production association Lenneftekhim in 1996 to join ILLA as a researcher. She got her PhD in Physical Chemistry (specialized in oxo-process phase equilibrium at high pressures) from the Leningrad State University in 1975. She has 4 patents and about 40 published articles on phase equilibrium and thermodynamics. Being an expert in fractionation and extraction, Tatyana is a senior research assistant also engaged in calculations and analysis of separation process.

Yuri Koshelev

As a researcher joined ILLA in 1997 after years of successful work for Lenneftekhim. A graduate of Leningrad Technology Institute, he got his PhD in Chemistry in 1973. Originally involved into synthesis and study of aromatic properties of products used for dyestuff, Yuri is an author of more than 20 patents and about 60 articles dedicated to production of aromatic hydrocarbons from natural gases, hydrogenation of synthetic fatty acids into alcohols, phenol treatment etc. He is specialized in development of catalysts utilized in oxidation and hydrogenation processes, his real area of expertise though being heterogeneous catalysis in phenol and acetone production process.

Vasily Trubaev

Started his career in ILLA as an engineer in 1998 after graduating from the Chemical & Biochemical Equipment Optimization Department of the St.Petersburg State Technology Institute in 1997. He received his PhD in Process Engineering in 2000. The author of one patent and several publications on hydrodynamics of liquid-gas jet devices and cumene oxidation. Presently, Vasily is the head of the Project Engineering Department. Area of expertise: process equipment design, calculation of multiphase media hydrodynamics, development of mathematical and dynamic models for various chemical processes (including HC oxidation and heterophase reactions).

Valentin Nyrkov

An extra-class expert in process engineering with an over 25 years experience of work with phenol. He graduated from Grozny Petroleum Institute in 1971 (process engineer specialized in organic synthesis) and started his career at Grozny Chemical Plant. The head of the 80 MTA phenol/acetone production unit, he had to leave Grozny after the Chechen war began in the early 90’s. Since that time he has been involved in ILLA’s projects contributing with his vast knowledge into the company’s success. Currently, he is involved into several projects as a consultant.
