Leading the change in the process engineering design

CONSER, as an independent process engineering design company, is devoted to the build up and license of advanced technologies. We focus on processes development, driving forward to meet customer requirements.
CONSER stands out in the scene of Italian process engineering companies for its faith in research, shown by its ceaseless investments in this field.
The company reputation and success is confirmed by the excellent performances of the plants brought on stream following its design and the satisfaction of the clients that have chosen CONSER.

With the aim to provide a service with optimum quality characteristics, all the project phases are managed.

This is valid both for new plants and for existing plants which requires debottlenecking to improve performances and enhance profitability.


In 2014 CONSER celebrated the anniversary of 45 YEARS IN TECHNOLOGY


CONSER was founded in Rome at the end of 1969, by a group of engineers coming from CTIP, each one with different skills: Salvatore Cassarino , expert in petrochemical technologies, Luigi Sibilia and Aldo Appetiti, experts in refinery field, and Amedeo Mencuccini, expert in software applied to chemical engineering.


The seventies were the years of growth, both in petrochemical and refinery, with more than 300 new projects. Some of those in close collaboration, for what is relevant to technology development and design, with the Italian company SIR. In this period some of the most important technology in our portfolio was born, among which: Epichlorohydrin (ECH), Propylene Pxide (PO) and Butyl Rubber (IIR).
It is significant that in 1975 Flavio Simola started his professional career in CONSER, becoming the actual CEO and technology director.


Great boost in the refinery field, with hundreds of projects for the most important Italian refineries, such as: Eni-Agip, Saras, Isab-Erg, Api etc., sometimes in collaboration with other important licensing companies as Uop, Mobil, Shell, Union Carbide etc.


The activities were expanded all over the world, by licensing technologies to some of the most important industrial companies, among which Bayer in USA, Hanwha Chemical Corporation in Korea and Sinopec in China.
In the second half of this decade CONSER, in cooperation with Sisas group, focuses its research and development in petrochemical, with the upgrading of Maleic Anhydride (MAN) technology and its derivatives: Butanediol (BDO), Tetrahydrofuran (THF), Gamma-Butyrolactone (GBL), n-Methyl Pyrrolidone (NMP) and the THF polymer (PTMEG), together with the trimellitic anhydride and isophthalic acid.

2000 to 2018

In the last decade the company had a generation shift in management, further increasing its international activities, especially in the East, and gained important license contracts for ECH, MAN, PTMEG and IIR. Moreover the research and development activities took new strength growing independently from the manufacturers companies partnership.
In 2014 CONSER celebrated the anniversary of 45 YEARS IN TECHNOLOGY.
