IRESEARCH ON THE CORROSION OF CONSTRUCTION MATERIALS FISSURE MACHINERY HYDROCARBONS IN CONTAMINATED ENVIRONMENTS WITH STAFF FROM CORROSIVE BY CRUDE OIL DISTILATION
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
In the atmospheric distillation of crude oil facilities and in vacuum of the fuel oil were highlighted in uniform and uneven general corrosion, local corrosion in the form of points, spots, caves and cracking, selective, crevice, etc. .. All these forms of corrosion are dangerons, corrosion cracking, however, occupies a special place, because in a short time can switches off the machine or plant with hard consequences sometimes to assess. If sulfur crude oil processing appeared to corrosion cracking of austenitic stainless steel scales of DA-C1 column at the top, after 1.5 years of operation. Also, heat exchangers at the top of the columns DA and DV, with monel or carbon steel pipe. Hydrocarbon environments in the presence of additional factors, are potentially active for the emergence and development of corrosion cracking. The paper presents some aspects of metal corrosion crack to metal equipments in the crude oil distillation plants and fuel oil vacuum
