Comparative analyses of common project execution alternatives
With major projects (FIG. 1), alternatives are generally considered in overall project execution and in construction.
Coke drum and blowdown system overpressure protection design - Part 1
The blowdown (BD) system in delayed coking units (DCUs) receives waste streams generated during the coke drum (CD) decoking process to recover valuable hydrocarbons and water. In recent DCU designs, the CD pressure relief valves (PRVs) also discharge to this system and then to the flare system via the BD PRVs.
FCC operational changes to boost gasoline octane
The fluid catalytic cracking unit (FCCU) is one of the main units providing gasoline with high-octane numbers to the refinery gasoline pool.
Ultra-deep desulfurization of FCC gasoline: Reactive adsorption strategy
With an increase in concern for the environment, countries around the world are implementing stringent environmental regulations and are continuously pressuring refiners to reduce the amount of sulfur in transportation fuels—primarily gasoline and diesel—to combat airborne pollution caused by vehicles.
Project Management: Estimate skid and package dimensions
In the absence of vendor quotations or detailed engineering, preliminary dimensions of skids or packages can be estimated quickly using the ratio method.
Industry Perspectives: What are the opportunities for the global HPI?
In the February issue of <i>Hydrocarbon Processing,</i> our editors provided the results of <i>Hydrocarbon Processing’s</i> survey on the challenges that the downstream processing industry may face this year.
Digital: Digitalization—Why now?
The process industries are under threat.
Petrochemicals: Which network can fulfil the petrochemical sector’s desire to exploit Industry 4.0?
The global petrochemical industry has not been short of success.
The critical maintenance team: Do you have one?
Larger plants typically have planners and maintenance supervisors onsite, as well as operations personnel.
Fabrication of clad equipment and piping—Part 2
For pressure vessels, heat exchangers and piping in corrosive services, the materials in contact with the process are often required to be high alloys to provide a reliable service life.
