in working process of power transformer, which directly affects the safe operation of transformer oil temperature as well as the stability of the network, so vital to transformer oil temperature detection and control. Based on single chip and chip design of digital temperature measurement transformer oil temperature of an intelligent control system. The system uses a digital temperature sensor ...

SHAHAB is a PC- based simulator developed by Olefin Research Group (ORG), with the simultaneous simulation of the reactor, the firebox, the convection section and the transfer line exchanger in steam Cracking units. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. Using a rigorous kinetic model, a complete reaction network for rep...

The need for plastic corresponds with the annual rise in population. Meanwhile, waste that is improperly managed can negatively influence environment. Therefore, a more promising alternative recycling process needed to convert this into oil by cracking, and possibly assisted adding empty palm bunches. This study examines how modifications ratio of bunches Polypropylene (PP) percent liquid produ...

Light olefins such as ethylene, propylene, and butylenes, are basic building blocks for petrochemicals. Further, these olefins are also useful for production of clean fuels such as alkylates – which have high octanes but no sulfur, olefins, and aromatics – or as octaneenhancers such as ethers. The conventional olefin production process is steam cracking of C2−C4 light paraffins from natural gas...

H ydrophobicity operates over many scales, from the demixing of oil and water at the macroscopic scale to the folding of proteins in water at the molecular scale. The physics governing hydrophobicity at the two length scales are, however, fundamentally different (1). The hydration of large solutes is governed by surface tension, which favors lower surface area and causes oil drops to coalesce. ...

Abstract Fossil-based production of plastics represents a serious sustainability challenge. The use renewable and biogenic resources as feedstocks in the plastic industry is imminent. Thermochemical conversion enables molecular building blocks materials from widely available resources. Waste cooking oil (WCO) significant fraction these This work provides insights into thermochemical fatty acids...

Cross-linked protein crystals (CLPCs) are very useful materials in applications such as biosensors, catalysis, and X-ray crystallography. Hence, preparation of CLPCs is an important research direction. During the preparation of CLPCs, an often encountered problem is that cracks may appear in the crystals, which may finally lead to shattering of the crystals into small pieces and cause problem i...

This paper presents the results of channel cracking experiments performed on a multilayered structure. Room temperature creep behavior of a metallic underlayer was studied by using a newly developed channel cracking method. By the analysis of a channel crack propagating under tensile load in an elastic Si3N4 topical layer, the creep properties of an aluminum underlayer were determined. The expe...

A new D457 × 7.1 X65ERW oil pipeline leaked twice during the pressure test. The two failed pipes belonged to same batch of products from manufacturer. Failure analysis showed that cracks in 1# and 2# cracking propagated outer surface pipe wall inner along weld fusion line. inclusion phase distributed chains zone is speculated be root cause fitness-for-service this steel was analyzed using failu...
