Decontamination, Tank Cleaning and Degassing

Separatore

DEKO Development & Marketing develops technological solutions aimed to provide our clients full technical support during planned or unscheduled shutdowns.

DEKO is a CHIMEC technology able to guarantee a drastic reduction of the shutdown time and optimal safety conditions.

The main advantages of our technology are:

- Hydrogen Sulphide (H2S) knockout
- Gas and light hydrocarbons stripping enhancement
– Very effective de-oiling action
– Drastic reduction of deposits
– Minimization of pyrophoric ignition risk
– Odor abatement
– Waste water reduction
– Easy waste water disposal (directly to WWTP without any pre-treatments)

DEKO may be applied in Refineries, Petrochemical Plants and Oil-fields. For more details please consult our application list.

DEKO APPROACH

The growing success of our DEKO technology is based on the highly expertise of our technician in planning and executing the decontamination as well as on the possibility to benefit from a broad portfolio of highly performing chemicals.

Our Decontaminations always include a package of tailored solutions, whose success strictly depends on the Design Phase involving both CHIMEC and the client. This first step, often not properly valorized, is the key to select the most suitable application, products, choose the optimal operating procedure and minimize the costs.

According to our experience the achievement of the targets is anyhow possible only if an appropriate Monitoring Strategy is as well implemented.

The Monitoring Startegy allows a concrete and effective time optimization and thus an effective global cost reduction of the turnaround activities.

Please contact our expert for further details on the benefits of our deko technology.

EFFICIENCY RECOVERY

DEKO can assure an optimal efficiency recovery of several facilities, such as heat exchangers, absorbers and distillation columns. It provides great time saving during the unit shutdown by drastically reducing all the activities commonly required by a classic mechanical cleaning approach.

DEKO/eKO

An ecofriendly synergy between two applications, DEKO and Emission Knock-Out. It’s able to guarantee gas-free conditions as well as emissions neutralization through the application of specific and effective chemicals.

DESIGN PHASE

The Design Phase is the key for a successful result. In this phase the project can be studied and planned in every detail, all the available technologies are investigated to select the most suitable to achieve the technical targets. This phase is also essential to define all the solutions able to guarantee the highest safety standards and the minimization of every potential risk.

The aim of the Design Phase is to define:

- The flow optimization (for both vapor phase and liquid recirculation)

- The most performing chemicals/approach

- The optimal process parameters identification (temperatures, pressures, flow rates)

- The best monitoring strategy (strategic points definition, type of analysis and their frequency, process follow up, personnel in site optimization)

- The technical staff required

The Design Phase is also crucial for the safety aspects, that must be evaluated to plan all the necessary preventive and protective measures. In this phase we determine:

- A complete safety data collection

- The appropriate PPE (Personal Protection Equipment) according  to the contaminants present in the work environment

- The most appropriate sample systems according to the conditions of the sample to be collected and analyzed  

At the end of the Design Phase the stategy chosen and the relevant information are shared with all the people involved in planned meetings during which a complete and precise DEKO Plan is distributed.

MONITORING STRATEGY

The “around the clock “ presence of CHIMEC Specialized Personnel during the DEKO activities will ensure a complete and constant follow up of the process, in detail

SAMPLE COLLECTION AND CONTAMINANTS ANALYSIS

Samples are frequently collected in order to evaluate the process of decontamination . Additives concentration and the trend of the contaminants are strictly monitored. The sampling frequency is defined according to the criticality of the point and can be even each hour

PROCESS PARAMETERS AND CONDITIONS CONTROL

Continuous monitoring of pressures and temperatures of the whole system through control room data analysis and field instruments. Continuous flows monitoring and control on draining systems. Identification of cold spots and contaminated condensate accumulation, which are dangerous to the DEKO PROCESS

All these activities, followed by eventual troubleshooting actions , let us achieve the target required, minimizing the time and maximizing the safety.

DEKO PRODUCT RANGE

The success of CHIMEC DEKO technology is also due to the availability of a broad portfolio of chemicals which guarantee the maximum flexibility in the Design Phase and Execution, increasing to the highest level the percentage of successful decontamination.

Each line was developed in order to satisfy specific field requirement.
