This case study explores the static stress assessment of a continuous steam generation system (SGS) using finite element method analysis. The focus is on a small-diameter plant that utilizes molten salt to generate steam in a heat exchanger at a solar plant facility. The plant includes four sequential components: an
This case study presents a comprehensive review of gasholder sizing within a cokes gas network. The primary objective is to evaluate the impact of adjusting the gasholder size on reducing annual flaring volumes and providing a buffer for short-term discrepancies between cokes gas production and consumption. The study explores various
DRG was engaged to conduct a stress analysis for two sulphur recovery burners, adhering to ASME VIII Division 1 Boiler and Pressure Vessel Code. This analysis involved traditional Division 1 calculations complemented by Finite Element Analysis (FEA) to evaluate the impact of nozzle loads on critical junctions. Additionally, an assessment
This case study focuses on the finite element analysis (FEA) conducted for a filament wound coupler designed for 42-inch centrifugal cast fiberglass pipes. The objective was to evaluate the performance of the fiberglass coupler under various conditions to ensure it meets the required specifications. Analysis The filament wound couplers (FWC)
A comprehensive finite element method (FEM) analysis was conducted on a molten salt/oil heat exchanger used in a solar plant facility. This heat exchanger is one of three identical units connected in series, operating under high pressures and temperatures with significant pressure and temperature cycling throughout day and night. To
In maintenance operations involving a vacuum tower approximately 50 meters in height, additional scaffolding is necessary. This scaffolding introduces increased wind loads, which, in turn, can elevate compressive stresses at the base of the tower. Such elevated stresses may lead to potential buckling or localized high stresses within the tower,
At a Liquefied Natural Gas (LNG) plant, a new LNG bunkering line is being constructed to supply ships with liquid LNG. This project involves the installation of new piping, which will be completed in multiple phases. This case study focuses on evaluating the material stresses, as well as the loads
Since the early 1980s, cracks have been observed in the off-gas cleaning section of the ethylbenzene hydroperoxide (EBHP) reaction unit. To address environmental concerns, EBHP must be removed from the off-gas before flaring. This process involves absorbing EBHP in norit beds within norit vessels, followed by cleaning the vessels with
Finite Element Analysis (FEA) is conducted on the skirt-to-head weld of an Acetylene Converter to evaluate the impact of a hot-box installation.
