Valve Automation Solution for Unconventional Shale Gas Challenge

gas pipelineWith the rapid development of unconventional shale plays throughout the U.S. has come the challenge of transporting product to refiners and markets. The large number of wells and the high volume of natural gas being produced has led to an increase in the size and number of gathering and other midstream pipelines.

Proactive Defect Detection with Simulation Software

smelterThrough-wall leakers in cast valve bodies often can be the end result of undetected defective areas created during the metal casting process. Such failures in service are extremely undesirable for valve manufacturer as well as the end user and in many cases such failures could pose significant health and safety concerns.

This article details the challenging nature of defect detection as related to through-wall leakers in typical cast pressure containing units. A discussion of common casting defects and the limitations of common defect detection methods or nondestructive evaluation (NDE) is provided. Finally, casting process simulation is described and presented as a means of detecting and eliminating the casting defects that commonly lead to the failure of valve castings.

Improve Ethylene Conversion Part One: The Furnace

Action ShotOlefin production plants use a variety of feedstocks. The type of feedstock used will impact the type of recovery technology used, but no matter the feedstock, control valve performance is an essential part of plant operations.

In this, the first of a three part series, critical control valve applications in the furnace section will be discussed. There are alternative product recovery configurations, which include front-end de-ethanizer for plants utilizing light feedstocks and front-end de-propanizer for plants using heavier feedstocks, but the focus in this article is on the front end de-methanizer configuration because of its ability to allow for a variety of feedstocks.

Five Key Criteria for Selecting Low-Temperature Valves

Specifying and consulting engineers, engineering houses, original equipment manufacturers (OEMs) and end users depend on valves to control the flow of compressed air or other fluids and on cylinders to control motion. But the cold truth is that low temperatures can cause problems for these fluid automation devices all along the line—from selection and delivery to operation and maintenance.

Critical Control Valve Considerations for the LNG Market

lng plant largeThe relatively recent rise in demand for liquefied natural gas, or LNG, has fueled a boom with regards to the construction of import and export terminals. Since the early 1990’s the number of LNG exporting/importing countries has increased from 16 to 43. Couple this with the fact that large natural gas deposits are rarely located next to the huge arenas that consume them and you have the perfect storm that is the current LNG market.
