Decontamination of process installations

We offer the service of decontamination of refinery installations using active chemical foam. This technique allows in a relatively short time to clean the refinery column and restore nominal parameters of the installation.

    decontamination of process installations

    purpose of the decontamination process

    The planned shutdown of production facilities is a very labor-intensive period that often requires several weeks of downtime. Contaminated tanks, columns, heat exchangers or pipelines must be emptied for cleaning and degassing. Contaminants may contain hazardous components and harmful gases.

    The purpose of the decontamination process is to reduce as much as possible the downtime that runs from stopping the plant to proceeding with repair and maintenance work involving unsealing the plant.

    reduction of the installation’s overhaul downtime

    This effect is achieved by neutralizing and removing hazardous sulfides, hydrogen sulfide, benzene, volatile hydrocarbons and other undesirable process gases.

    To reliably achieve these goals, high-performance chemical cleaners with tailored cleaning and degassing methods are used. Cleaning and degassing of distillation columns and tanks can be performed with excellent results in a single day. The complete elimination of hazardous gases and potential fire hazards is of paramount importance.

    Mechanical cleaning and decontamination of storage tanks can require several weeks of downtime. In comparison, chemical cleaning and degassing significantly reduces downtime to a few days, with great economic benefits.

    We offer decontamination (cleaning and degassing) programs tailored to the needs and specifics of the installation. We develop technological solutions to provide our customers with full technical support during planned or unplanned outages. Our offer always includes a package of customized solutions, the success of which closely depends on the design phase in which the customer is involved. This first step, is the key to selecting the most suitable application, products, choosing the optimal operating procedure and minimizing costs.

    The purpose of the decontamination process is to reduce as much as possible the downtime running from stopping the plant to proceeding with repair and maintenance work involving unsealing the plant.

    phases of the decontamination process

    phases of the decontamination process

    We can distinguish two phases in the decontamination process:

    design phase

    monitoring phase

    design phase

    The design phase is the key to a successful outcome. In this phase, the project can be studied and planned in every detail, all available technologies are studied in order to select the most suitable one to achieve the technical goals. This phase is also necessary to identify all solutions that are able to guarantee the highest safety standards and minimize any potential risks.

    the goal of the design phase is to determine:

    1. Optimal flow parameters for both gas phase and liquid recirculation

    2. A list of the most effective chemicals

    3. Identification of optimal process parameters

    4. The best monitoring strategy (defining sampling points, type of analysis and their frequency)

    5. The required technical staff

    The design phase is also crucial for the safety aspects to be assessed in order to plan all necessary preventive and protective measures.

    in this phase we determine:

    1. A complete set of safety data

    2. The appropriate personal protective equipment, depending on the contaminants present in the work environment

    3. The most appropriate sampling systems according to the nature of the sample to be collected and analyzed

    monitoring phase


    Specialized personnel during the conduct of decontamination processes will ensure full and continuous control of the process, in terms of:

      • Sampling to evaluate the effectiveness of the implementation of the decontamination process, additive concentrations and contamination trends are monitored. Sampling frequency is determined by the criticality of the point and can be as high as every hour
      • Continuous monitoring of pressures and temperatures of the entire process by analyzing data from the control room and using field instruments. Continuous monitoring and control of flows in dewatering systems

    features and benefits of using the decontamination process

    highly economically efficient method

    • Reduction of steam consumption for the process (up to 90%)
    • Significant reduction in cleaning time compared to other methods
    • Low consumption of chemicals used in the cleaning process
    • Reduced cost of waste disposal and management
    • Reduced cost of waste disposal and management

      environmentally friendly technology

      • Substances used are biodegradable
      • Low toxicity (pH: 8-9)
      • VOCs permanently bound in the solution phase
      • No negative impact on the biological life of wastewater treatment plants
