FITNESS FOR SERVICE AND RELIABILITY OF MATERIALS FOR MANUFACTURING COMPONENTS INTENDED FOR DEMANDING SERVICE CONDITIONS IN THE PETROCHEMICAL INDUSTRY

A methodology has been developed to quantitatively assess the suitability of use and fitness for service of candidate materials using a novel approach that includes multiple perspectives.As a case study, a carbon steel pipe has been selected for operation in the petrochemical sector.The materials studied were the following: American Petroleum Insti

Humic acid (HA) was Moisturizing Lotion extracted by a hydrothermal method from Huolinhe lignite from Inner Mongolia.The effects of the alkali-to-carbon mass ratio, water-to-coal mass ratio, reaction temperature, and reaction time on the HA yield were investigated.The physicochemical characterization of the products was performed, and the reaction

A two seasons capture-recapture study was preformed between 2016 and 2017, focusing on the Carabus species living in a suburban park in Budapest, Hungary.Eighty-four live-capture non-baited pitfall traps were placed in a grid covering an area of 567 m2.Five Carabus species were captured in the park from the nine species in the potential species poo
