Compressors
Understand net gas compressor control logic from a process engineering standpoint
In a refinery or petrochemical plant, certain equipment can create “gray areas” between process engineers and instrument engineers.
Resolving vibration problems in a crude booster pump
The pumps referred to in this article are 2,600-HP vertical pumps utilized as booster pumps for the shipment of crude oil.
Confirm best practices for compressed air in refineries
Within a refinery, four main utilities are considered essential to operations: electricity, natural gas, water and compressed air.
Maintenance and turnaround planning critical to successful ejector vacuum system operation
Steam ejector vacuum systems are generally considered to be reliable and require little maintenance.
Fouling mitigation strategies for process gas compressors in olefins plants
Indorama Eleme Petrochemicals’ olefins plant in Port Harcourt, Nigeria is designed to produce 300,000 tpy of polymer-grade ethylene and 126,000 tpy of polymer-grade propylene through the pyrolysis or thermal cracking of natural gas liquids (NGL).
Selecting flare gas recovery system for a greenfield refinery
Overall energy management and operational conservation have become crucial factors for profitability in today’s refining segment.
Innovations
Ross Systems and Controls (SysCon) recently completed the qualification to self-certify its touchscreen purged panels as meeting the rigorous standards of Underwriters Laboratories’ UL-698A Code and the National Fire Protection Association’s NFPA-496 Code.
Advancing export terminal technology: An optimized process for the refrigeration of cryogenic hydrocarbons
Ethane production in North America (NA) has expanded dramatically with the onset of shale production and associated hydraulic fracturing. Ethane concentrations in fractured shale gas are typically 10% or higher vs. a traditional range of 4%–7% in associated gas.
Maximizing energy efficiency in paraxylene production—Part 2
Due to reduced margins, higher energy costs and rising atmospheric carbon dioxide content, energy efficiency has never been more important in refining and petrochemicals. This is particularly true in the modern aromatics complex, which produces paraxylene (pX), benzene and other aromatics from naphtha.
