Selection of cooling water system for gas, petroleum and petrochemical plants located on coastline - Part 1

Safamirzaei, M., Namvaran P&T

Cooling water systems play an important role in today’s industry.

Improve CCR reforming profitability using a novel high-density catalyst

Takahashi, H., Fuji Oil Co.; Nakamura, Y., Nikki-Universal Co.; Chang, J., Honeywell UOP

Catalytic reforming has been a staple in petroleum refining since 1949.

Solve gravity separation challenges

Majeed, K. T., Mahsan Consulting Services Ltd.

Separation of oil, water, gas and solids (sand) droplets/particles is one of the most common requirements in most oil and gas facilities.

Develop reactor internals for optimizing reactor design - Part 2: High-performance mixing chamber

Ahn, E. S., Park, S. I., Song, I. C., Kim, G. B., Chang, G. S., GS Engineering and Construction

Most hydroprocessing reactors are fixed-bed reactors comprising several catalyst beds that are divided by quench zones containing mixing chambers that introduce a vapor-quenching medium.

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

Tao, Y., SINOPEC Engineering Inc.

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.

Digital: Digitalization—Why now?

Micklem, D., KBC, a Yokogawa Company

The process industries are under threat.

Fabrication of clad equipment and piping—Part 2

Shargay, C., Carmona, R. K., Daru, K., Desai, J., Irfan, M., Fluor; Panchal, A., Reliance Industries Ltd.

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.

Understand net gas compressor control logic from a process engineering standpoint

Hong, R., Chang, G. S., GS Engineering and Construction

In a refinery or petrochemical plant, certain equipment can create “gray areas” between process engineers and instrument engineers.
