Chemical Tank Lining for Oil Storage Tanks in Iraq
Best HDPE Geomembrane materials is a new type of special anti-seepage and anti-corrosion material, using good-quality imported high-density polyethylene white resin, the main component is more than 97% of high-density polyethylene, about 3% carbon black, Heat stabilizer, anti-aging material, ultraviolet absorber, blow molding by a single layer, double layer, three-layer co-extrusion technology.
HDPE Geomembrane chemical tank liners were used as an anti-seepage layer in oil or chemical product conservancy projects. Now Iraq attache great importance to environmental protection. Oil and gas engineering must lay anti-seepage HDPE Geomembrane, which is very important. Once the oil storage liner leaks, it will pollute underground resources. Based on this, heavy-duty geomembrane liner, such as chemical tank liner, is used as a means to prevent the leakage of petroleum products into the ground during the design and construction of the tank first. The protective liner impermeable HDPE geomembrane has a good heat resistance and cold resistance. good chemical resistant, high hardness, and toughness, good mechanical strength, environmental stress crack resistance and tear resistance strength performance, as the density increases, the mechanical properties, and barrier properties will increase, tensile strength and heat resistance Also higher, resistance to corrosive liquids such as acids, alkalis, and organic solvent.
The construction of large oil storage tanks in Basra, Iraq was built in the suburb. These oil storage tanks are likely to cause settlement and deformation, leading to liquid leakage in the oil storage tanks. To prevent liquids leakage from causing damage to the environment, anti-seepage measures have been added to the design and structure of the oil storage tank construction. At present, from the design and construction of Iraqi customers, the most effective method in this regard is to set an anti-seepage HDPE membrane on the basis of the oil storage tank and harden the ground in the oil storage tank area and combine it with the firewall to form a closed anti-seepage Space to ensure anti-seepage and leakage.
The volume of each oil storage tank is 50 x 50 square meters, and there are 10 oil storage tanks in total. To meet the requirements of environmental protection and anti-leakage, the requirement of laying anti-seepage membrane is: the anti-seepage layer is lined with a 2mm high-density polyethylene geomembrane chemical tank with a width of 8.0m. Each diaphragm is welded on both sides by a lap joint, and the lap width is not less than 100mm. (Each department designed the anti-seepage layer as a 2mm high-density polyethylene geomembrane). Geomembrane and other materials are required to follow the GRI GM 13 quality standard.
