Prevent methane hydrate formation in natural gas valves
The discussion here focuses on the thermodynamics involved and on the requirements for a successful natural gas valve application in which the incidences of hydrate formation and icing of the valve are reduced.
Consider both actual and virtual spare parts inventory
Globally, hydrocarbon processing industry (HPI) facilities operate hundreds of thousands of fluid machinery assets. The various service-specific internal components of these assets are supported by ma..
Consider novel CGC and front-end depropanizer system for olefins production
In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.
Enhance operation and reliability of dividing-wall columns
Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux..
Optimize vacuum ejector operations
Vacuum distillation unit (VDU) designs generally involve jet ejectors due to their low capital and operating expenses, high reliability, durability and simplicity. Once the ejector is installed and co..
HP Reliability: Manage your time constructively
We often view ourselves as very efficient reliability implementers. Yet, as professional engineers, we take action to save time, accomplish more and reduce stress by applying better time-management sk..
HP Integration Strategies: Asset information management improves life cycle benefits for equipment
Traditionally, the various production management and asset management systems in the hydrocarbon processing industry (HPI) and other heavy industries resided in silos with separate management, archite..
HP Viewpoint: Consider integral-gear compressors in CO2 services
In 1998, the author began researching suitable technology for compressing 95 MMSCFD of “bone dry” (–100°F dew point) carbon dioxide (CO2) from 16.7 psia to 2,710 psia. The compress..
HP Engineering Case Histories: Case 72: Interaction between disciplines when troubleshooting
When troubleshooting, we can become fixated on the discipline that we are most familiar—in the author’s case, mechanical engineering. Investigating the failure of a machine may have a group ..
HP Impact: Global oil flows shift from West to East
By 2020, crude oil trade flows west of Suez will drop by 4.2 MM bpd, while crude flows east of Suez will rise by 4.7 MM bpd (Fig. 1), according to a recently published report from ESAI Energy. The pri..
