CONSER is an Italian Process Engineering Design Company founded in 1969 providing Licensing and Basic Design to chemical process industries and high quality technical consulting services.

With over 50 years of experience and its constant confidence in research, CONSER is able to deliver up-to-date, creative and innovative solutions tailored for every client needs. Thanks to this client-oriented approach and its wide portfolio of patented licenses and technologies that export all over the world, CONSER's reputation and success are well known, confirmed by satisfaction of the clients which have chosen it.

With the aim to provide a service with optimum quality characteristics, all the project phases are managed. Starting with feasibility studies, process development, licensing of processes and know–how transfer, process design package preparation, supervision of detailed engineering and construction, CONSER follow its client up to and including assistance to initial start-up. This is valid both for new plants and for existing plants which requires debottlenecking to improve performances and enhance profitability.

In addition to Advanced Technology Licensing and Process Design Package, CONSER offers activities of Research and Development, Plant Debottlenecking and Revamping, Operation Analysis, Energy Saving and HSE Solutions for the mitigation of the Environmental Impact in plant operations.

In parallel, CONSER carries out its research and development activities in collaboration with important international players and Universities research centres.

As main result of our intense and continuous development and passion for research, CONSER developed several patent applications, to protect its intellectual property and over the years, new patents have been successfully granted for new technologies.

CONSER by numbers: more than 50 years of experience, over 500.000 Metric Tonnes per Year of chemicals produced worldwide using CONSER know-how, over 30 countries hosting CONSER technologies, over 150 satisfied clients around the world, 50 up-to-date and optimised technology licenses.

    License Technologies in Petrochemical Industry

    CONSER experience is based on an extensive “know-how” of chemical and petrochemical technologies, up-to-date to the highest industrial standards.

    CONSER technical solutions are specifically tailored to clients’ needs, in order to achieve the best cost/effective solution, preserving a high degree of flexibility, operability and safety.

    In the design phase, critical challenges like by-products management, effluent and emission disposal and product quality assurance are the foundations of the solutions proposed by our process department. All the project phases are managed, from feasibility studies and process development up to and including assistance to initial start-up.

    CONSER’s industrial experience in the petrochemical and chemical fields include the design of plants for hydrocarbon pyrolysis for the production of olefins and aromatics, chlorinated derivatives, organic acids and anhydrides, glycols, amines, resins, pharmaceuticals, specialty chemicals and the processing and recovery of aromatics.

    In the section "Gallery & Media" is reported a list of petrochemical technologies in CONSER's portfolio, relating to CONSERS’s development experience and know-how.

    Research & Development (R&D)

    CONSER is devoted to research activities for the development of new processes and technologies.

    CONSER has always been standing out in the scene of Italian process engineering companies for its faith in research, shown by its ceaseless investments in this field.

    All the technologies we offer are fully and deeply developed, from the laboratory scale to the full commercialization scale, in order to provide to the clients the most advanced feasible and cost-effective solution.

    As main of the result of our intense activity of research, CONSER developed several patent applications, to protect its intellectual property.

    CONSER’s latest research efforts to improve different systems and processes include:

    • Epichlorohydrin (ECH and ECH-EF)

    • Maleic Anhydride (MAN)

    • 1,4 Butandiol (BDO)
    • Tetrahydrofuran (THF)

    • Gamma-Butyrolactone (GBL)

    • Propylene Oxide (CHPO and HPPO)

    • Methyl-Isobutyl-Ketone (MIBK)

    • Butyl-Rubber and Halo-Butyl Rubber (IIR/HIIR)

    • Bio-Succinic Acid’s Derivatives

    Process development is achieved through ongoing research activity, with the goal of successful commercialization, evaluating alternative competitive routes, capital and operating costs, environmental sustainability and inherent process safety.

    CONSER is keen to cooperate with producing companies to transform innovative ideas into new or improved processes, allowing to meet the industry’s stringent demands of tomorrow.

    R&D activities are run in association with producing companies, qualified laboratories and research centres.

    Among them, the most prestigious Italian universities:


    Health safety and environmental
