Assessment of Hydrate Prediction Software for MEG–Water–NaCl Systems
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study evaluates the performance of three industry‐standard simulation tools—Aspen HYSYS (V14), Multiflash (V7.5), and OLGA (V2024.1)—by comparing predicted hydrate dissociation temperatures with experimental data obtained from a PVT sapphire cell.

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis
Animal Research and One Health, EarlyView.Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

Requirements on pipeline steel
Steel in Translation, 2010The current state of high-strength pipe-steel production is reviewed. Unsolved problems are identified. The considerable expense of improving the properties of pipe to meet Russian pipeline requirements (steel of strength class X80 or higher) on the basis of existing production methods is highlighted.

Molybdenum steels for pipelines
Canadian Metallurgical Quarterly, 1975AbstractStringent property requirements are specified for steels to be used for oil and gas pipelines, especially for application in extremely cold climates. The effect of controlled plate mill processing (including water spray cooling between hot rolling passes), and of simulated strip mill processing on the mechanical properties and microstructure of

International Journal of Pressure Vessels and Piping, 1974
Abstract This paper reviews the measures taken in Canada to prevent failure in oil and gas pipelines, the former relying on prevention of initiation by a ‘leak-before-break’ approach, the latter by measures aimed at preventing fracture propagation. The effect of stable slow crack growth is discussed.

Journal AWWA, 1949
MAJOR steel water supply lines require great care in their design to provide for ability to withstand pressures safely, to support long spans adequately and to insure long life. Equal care must be given to insuring satisfactory operation of the line by providing the proper accessories at the proper places and in the proper sizes.

Contralled Rolled Steels for Offshore Pipelines
Offshore Technology Conference, 1976ABSTRACT Controlled rolled X60, X65 and X70 steels, originally developed to meet the stringent requirements of Arctic pipelining, have been used in offshore oil and gas pipelines. The technology and application of these acicular ferrite and pearlite reduced steels, which have been used successfully in several North ...

Impact Toughness of A Pipeline Steel
Canadian Metallurgical Quarterly, 1977Abstract Impact fracture toughness of a pipeline steel was studied as a function of temperature and of the orientation of the crack with respect to the rolling direction. Toughness criteria, such as JId and KId, were determined. Precracked Charpy specimens were used in this investigation.
