Modern LNG receiving terminals are often configured with LNG piping outside of the tank impoundment area with troughs and trenches to capture any releases from such piping. The trenches and troughs are inclined to guide the spill toward a bund, sump or an area that is within impoundment walls...

Over the past few years, the use of computational fluid dynamics (CFD) models for safety analyses of LNG facilities in the United States has been steadily increasing. However, with the notable exception of offshore terminals, for which the use of CFD models is required by the U.S. Coast Guard, the...

Refinery crude units often process variety of feedstocks. If properties of the feed entering the crude unit are not precisely known, it is difficult to predict how changes in the tower operating conditions will affect properties of the products. Similarly, if on-line analyzers are not available, it...

For many years, the LNG industry has focused on large baseload plants. Recently, more attention is being given to smaller LNG facility sizes and alternative liquefaction strategies. This presentation will examine the impact that the thermodynamic efficiency of a particular cycle can have on the...

Control of feed pH control is an important task in chemical industries, wastewater treatment, polymerization reactions, fatty acid production and biochemical processes. However, this is a challenging problem due to (i) presence of large and varying time delays and (ii) complex time varying...

The characteristic of gliding arc in tornado was investigated under different experimental conditions and the destruction of PCDD/Fs (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) in medical waste incinerator fly ash by using a dc gliding arc in tornado reactor was studied in the...

Coke oven gas (COG) is a by-product when producing coke from coal. It is not always easy to make use of COG, causing waste of energy. Producing liquefied natural gas (LNG) is an efficient way of utilizing COG. The amount of hydrogen affects liquefaction process significantly, because its thermal...

The main purpose of this work is to optimize natural gas liquefaction process by reducing energy consumption. At first, a rigorous simulation of natural gas liquefaction is conducted. Based on the simulation results, the refrigerants and natural gas thermodynamic states along with whole process are...

Since the restart of its expansion in 1985 with Woodside plant, OEM has tried to support the growth of LNG market all over the years by introducing always-new technologies for both driver and driven equipments. Nowadays, new challenges are emerging from the market, asking the OEM to give its...

Carbon dioxide emissions from conventional coal-fired power plants constitute the majority CO 2 emissions in the U.S. Mitigation of CO 2 by chemical conversion provides an alternative method to reduce the CO 2 emissions from coal gasification process with the benefit of eliminating energy-intensive...
