Coke drum and blowdown system overpressure protection design—Part 2
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.
Digital: Cloud-based dynamic simulation models amplify operator training and safety programs
International oil and gas (O&G) and hydrocarbon processing industry (HPI) companies are under great pressure to be profitable.
Reliability: Safe fluid machines are our responsibility
Early in our training as engineers, we developed the ability to collect and evaluate data.
Editorial Comment: Where some see roadblocks, we see opportunities
In the January issue of Hydrocarbon Processing, the editorial comment focused on the roadmap to advancing ideas.
Innovations
Industrial workers can strengthen their grasp of production and make more informed operating decisions with the new Allen-Bradley CompactLogix 5480 controller by Rockwell Automation.
Business Trends: How plastics waste recycling could transform the chemical industry
If plastics demand follows its current trajectory, global plastics-waste volumes would grow from 260 MMtpy in 2016 to 460 MMtpy by 2030, taking what is already a serious environmental problem to a new level.
Selection of cooling water system for gas, petroleum and petrochemical plants located on coastline - Part 1
Cooling water systems play an important role in today’s industry.
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.
