Polymeric liners for tank reconstruction (PER-SV type)

New life for old tanks

Reconstructible tank

DESCRIPTION

Purpose

Polymeric liners (PEV type) are designed for impermeable storage of crude oil, diesel fuel, chlorine, acids, caustics, water, liquid mineral fertilizers and food liquid products.

Sphere of application:

According to experts, currently 70% of the tanks that are intended for storage of oil products in Russia are tanks with the age of 20-30 years. Sometimes the reconstruction of equipment that has already finished its service life is more economically feasible than the construction of a new one. This is especially true for high-capacity metal tanks, as their dismantling and disposal entail many problems.

Company JSC NPF "Politechnika" offers you to use innovative technology to extend the service life of metal and concrete tanks with the use of soft polymeric materials.

Materials

Polymeric liners (PEV type) are made with advanced technologies of high-strength polymer composite elastomers coated with PVC, TPU, PVDF, PVDC, LLDPE, HDPE, depending on the type of aggressive substance stored. They consist of polyester fabric and represent a closed cylindrical shell with a technical manhole (hatch) mounted in it for connection to the system, they can also be of cylindrical shape with an open top.

Modifications of liners:

for open type tanks (PVC-based);
for closed type tanks (based on polyurethane foams and multi-layer composites).

Installation of liners:


1. The soft polymeric liner folded in a roll is put in the tank using the crane.	2. The liner shell is unfolded on the bottom of the tank.	3. The shell is fixed along the perimeter of the bottom of the tank and on its technological parts.	4. The side panel shell of the liner is raised to the walls and fixed on the edge of the roof and parts of the walls of the tank using the lifting blocks and winches temporarily mounted on the edge of the roof of the tank.

Prior to installing a polymeric liner (PER-SV type) it is necessary to perform following operations:

cleaning of surfaces to the required degree, phosphating the inner surface of the tank (creation of chemical corrosion-resistant film of insoluble phosphate);
inspection of wall thickness with non-destructive testing methods for compliance with regulatory requirements;
application of primer or polymer compositions (optional).

Installation of the liner is recommended in the warm season (at temperatures up to minus 10°C).

The advantages of using polymeric liners (PER-SV type) compared to alternative technologies to majorly repair and reconstruct the tanks:

Economic benefit of up to 500%. Reconstruction of the tank with the use of polymer liner is 5-6 times more profitable than major repairs. No costs to replace worn-out and corrosion-affected steel sheets are required. Under normal operating conditions, there are also no additional costs associated with the maintenance of the tank from the inside.
Versatility. The technology is suitable for use on both metal and concrete tanks with a capacity of 1 to 5 000 m3, for a variety of liquids (technological aqueous solutions, petroleum products, fertilizers).
Minimization of product losses. Leakage from the tank provoked by cracks resulting from deformation of the joints of the sidewall and bottom is avoided.
Efficiency. All installation works are carried out in very short time (from 3 days) and with minimal use of manual labor.
Mobility. Transport dimensions allow the polymer liner to be delivered to hard-to-reach areas with the lowest logistics costs.
Fire safety. This technology does not require fire works, which is especially important for refineries or for organic synthesis plants. No need to issue repair permits.
Durability. The service life of the tank reconstructed using the polymeric liner is up to 5 years and can be extended repeatedly by replacing it with a new insert with mandatory monitoring of the state of the metal walls of the tank.
Ecological compatibility. Polymeric materials used to restore the tanks are chemically and biologically inert — they do not rot, do not decompose, are not affected by fungus, do not affect the quality of the product stored.

In March 2016, a field fuel storage facility of PSG-5000 type was commissioned at our mine, it consists of 20 elastic tanks of PER-250 type, with a total capacity of 5000 m³. The reason for the installation - the replacement of obsolete elastic tanks of type ArcticKingTank 125 m³ produced by SEIIndustries Ltd (Canada). Equipment and materials of PSG-5000 were delivered to the site in full completeness and in good condition. The kit takes into account everything, up to rags, and with sufficient stock. Installation supervision works on installation of tanks are organized at a high level, performed as soon as possible and efficiently, despite the harsh weather conditions. During the period of operation of the tanks, no deficiencies were identified.

In September 2014, LLC NPF "Politechnika" carried out for JSC "NNK-Taimyrneftegazdobycha" rapid delivery, deployment, installation and commissioning of a field fuel warehouse (PSG) with a capacity of 3000 m³. Thanks to the competent organization of installation works by the contractor, despite the severe weather and climatic conditions, the warehouse was prepared for acceptance of fuel in the shortest possible time. During the work process, the contractor's specialists not only participated personally in the installation, but also trained the employees of JSC "NNK-Taimyrneftegazdobycha" in order, features of operation and maintenance of tanks, unit acceptance, procedures for minor repairs of products. It is also necessary to note the ease of deployment of both the canopies and the tanks themselves (the elementary presence of metal rings on the canopies and the presence of welded handles on the tanks removes a lot of problems on their deployment). Such approach to the project also makes cooperation with NPF "Polytechnic" attractive in comparison with other similar manufacturers.
