Drying and pressurisation
Drying operations are needed to dry equipment after maintenance, be it pipelines, tanks or reactors, leaving an extremely low degree of relative humidity: drying helps to keep the purity of the product under control when plant is restarted, to minimise corrosion and to increase safety and general control over the process. At the end of drying, to prevent humidity or oxygen in the environment from getting into the equipment, it is pressurised with nitrogen.
SOL provides integrated solutions for drying and pressurisation processes, making it possible, thanks to the characteristics of the nitrogen supplied, to reach the lowest dewpoint possible in a limited time and at limited cost. The nitrogen is pumped through the equipment to be dried at controlled temperature, pressure and flow, using apparatus specifically designed for this activity: continuous monitoring of the process parameters, in representative positions for correct execution) ensure the process is carried out properly and the plant left ready or prepared for later operations.
The main advantages of nitrogen drying are thus the very low dewpoint that can be established inside the treated apparatus, and the consequent inhibition of corrosion: the plant is left in a safe condition thanks to the inert nature of the gas.
Thanks to cooperation with highly-qualified operators, and to the availability of specific apparatus and qualified personnel, SOL can provide its customers with customised, extensively tested solutions, through cooperation right from the initial design and planning phase of maintenance operations, to establish the best and most effective protocols for carrying out the entire process.
