Take the mystery out of running your LNG plant

5/19/2023

While process simulation software can be used by plant engineers to calculate the dewpoint temperature of mixed refrigerant, this is of limited use to the plant operators at the control panel in maintaining an appropriate amount of mixed refrigerant superheat as they adjust the plant. To address these challenges, the authors’ company has developed a simplified method of calculating mixed refrigerant superheat that can be programmed in the distributed control system (DCS) and made available to panel operators.

Using data to digitalize the oil and gas industry

1/1/2023

The oil and gas industry has been historically slow to adopt new technologies and truly take advantage of the digital tools that are widely available and extensively used in other sectors.

How boil-off gas APC exceeded expectations at an Australian LNG plant

1/1/2023

The use of advanced process control (APC) technology on LNG liquefaction trains is well accepted with some of the earliest implementations developed in the late 1990s.

Protecting the workplace and employees: The critical role of security technology

12/1/2022

When it comes to the benefits that an integrated security solution offers to suppliers in the energy sector, the first topic of discussion is almost always centered on minimizing risk to physical site assets and data.

Reduce gas dehydration costs with high-efficiency mixing

12/1/2019

The gas dehydration process is typically carried out using a large contactor tower, where glycol [typically triethylene glycol (TEG), ethylene glycol (MEG) or diethylene glycol (DEG)] enters counter-currently to the process gas for optimum contact between glycol and gas during mass transfer.
