Abstract

The main consideration for choosing glass fiber reinforced polymer (GFRP) tank for chemical fluid vessel is the corrosion resistance property of the material. There are leakages on one of the three sludge palm oil GFRP tanks after two years operation in a palm oil refinery industry at East Borneo (Kalimantan Timur). The structure of the tank body consists of chemical barrier laminate and structural laminate. The chemical barrier laminate is composed of bisphenol as matrix with surfacing veil and three laminates chopped strand mat as reinforcement, while the structural laminate is made of isophthalic as matrix with filament winding as reinforcement. This paper discusses the failure and strength analysis of the tank structure and the results are used to make a decision for reconditioning the three GFRP sludge palm oil tanks. Wrinkle and resin pocket near the inner surface of the tank when exposed to sludge palm oil at temperature over than 90 O C caused the matrix to become hard and b...
