Special Focus: Clean Fuels

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.

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.

Process Engineering

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.

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.

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.

Catalyst

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.

Heat Transfer

Assess remaining life for heater tubes
Patel, R., Singh, J., Ashutosh, Engineers India Ltd.

Refineries and petrochemical plants form some of the major sections of the hydrocarbon industry and consume much of the fuel that is burned in furnaces (heaters and specialty furnaces, such as reformers and crackers) to meet process heating requirements.

Project Management

Comparative analyses of common project execution alternatives
Rentschler, C., Engineering Consultant; Shahani, G., ShureLine Construction

With major projects (FIG. 1), alternatives are generally considered in overall project execution and in construction.

Environment and Safety

A cost-effective approach to monitoring dangerous hydrogen sulfide gas
Hernandez, J., Emerson Automation Solutions

Hydrogen sulfide gas (H2S) is one of the most common hazards in the oil and gas industry.

Asia: Japanese refining moves towards consolidation and increased efficiency
Gerden, E., Contributing Writer

According to recent statements of leading Japanese analysts in the field of refining and the country’s largest producers, the Japanese refining industry is moving towards consolidation and an increase in efficiency.

Engineering Case Histories: Case 106: Delayed fireball type explosions
Sofronas, A., Consulting Engineer

When a vessel containing a flammable liquid under pressure (such as those in an LNG road tanker truck) ruptures and ignites, a vapor fireball explosion can occur.

Viewpoint: Downstream expansions will accelerate needed production growth
Al-Judaimi, A. M., Saudi Aramco

Two transformative drivers—global economic growth averaging more than 3%/yr and the world population expanding to more than 9 B by 2040—will have the net effect of adding another India and China to today’s global energy demand.

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.

According to Hydrocarbon Processing’s Construction Boxscore Database, new project announcements are nearly 28% higher in 1Q 2019 compared to 1Q 2018.

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.

Industry Metrics
Rhodes, Mike, Hydrocarbon Processing Staff

All main US products performed positively as refinery product outputs declined considerably and led to a fall in inventory levels, fueling bullish sentiment.

Global Project Data
Nichols, Lee, Hydrocarbon Processing Staff

Hydrocarbon Processing’s Construction Boxscore Database is tracking nearly 1,300 projects around the world.
