The project was designed and installed tanks. TK-102 / TK-102Zs. (Tank hydrocarbons four atoms; C4 Monomer original blade) (Figure 2.75) tank TK-501 / TK-501Zs. (Tank hydrocarbons four atoms; C4 Raffinate as usual), which plans future applications in the chemical group Volatile Oil such as hydrocarbons 5 atoms (C5), hydrocarbons nine atoms (C9), etc., must be designed accordingly. Standard ASTM. SECT VIII DIV.1 or 70, with a design pressure of 6.0 kg / cm2-g and a temperature of 50 degrees Celsius designed to test the strength of the reaction with water tank (Hydrostatic Test) at a pressure of 9 kg / cm2. -g
