How Turboexpanders with Variable Inlet Guide Vanes Increase LNG Production Flexibility
11 June 2021

Radial inflow turbines (RIT), or turboexpanders, have become not only essential to the oil and gas industry, but also to specific applications in the realm of liquefied natural gas (LNG). Variable inlet guide vanes (vIGV) are RIT’s unique feature, rendering the turboexpander as a variable geometry turbomachine. In turn, this makes a turboexpander an effective solution for variable load and flexible LNG production.

Real Time Measurements of Water in Ethylene and Propylene with an Online TDLAS-Based Analyzer
14 May 2021

The petrochemical industry needs ethylene and propylene purity analysis. The precision and reliability of these measurements, as well as speed and cost reduction, are important to prevent potential process upsets and to assure optimum throughput. The faster a reliable purity measurement can be achieved, the greater the product to market. For this reason, any significant advance in ethylene purity analysis that promises to lower costs and increase speed without sacrificing accuracy can have a major impact on the profitability of ethylene and propylene production plants. This paper describes the use of Tunable Diode Laser Absorption Spectroscopy (TDLAS) for extractive measurements of moisture in the processes of ethylene and propylene production.

Detailed Planning & Expert Support Ensures Reliability
10 May 2021

Unexpected emergencies happen but can be mitigated with proper maintenance planning. Proactive maintenance is vital for long-term profitability. Implications for delaying machine maintenance includes losses to production even pre-outage and postponing scheduled maintenance may result in a larger workload during an outage timeframe. With proper forward planning, costs can be reduced by up to 20%. Read more to see how.

How a Dividing Wall Column Maximizes LPG Recovery - GT-LPG MAX℠
21 April 2021

GT-LPG MAX℠ was developed by Sulzer GTC Technology using dividing wall column (DWC) technology to optimize overall operation and enhance C3+ recovery. A DWC can separate a multi-component feed into three or more streams within a single column. The deethanizer and depropanizer columns in a traditional LPG recovery system are replaced with one column using a dividing wall to achieve as high or higher C3+ recovery as a conventional design. As a result, both capital investment and operating costs for grassroots and revamped applications are reduce.
