Equipment

Machinery: Soft skills and habits all machinery professionals must develop—Part 1

Perez, R. X., Consultant

When I ask people that work around machinery, “How do you improve reliability?” they often tell me to buy better bearings, seals, monitors or some other hardware-based improvement.

HF alkylation conversion is finally within reach—Part 1

Because of its clean-fuel properties (paraffinic, high octane, low vapor pressure and very low sulfur), alkylate is considered one of the most desired components in the gasoline pool.

FCC collector tray leaks impact column operation

Hanson, D., Brown Burns, J., Teders, M., Valero Energy Corp.

In the collective experience of the authors, one of the most troublesome pieces of refinery fractionation equipment is the collector tray.

Identify the cause of liquid maldistribution inside packed beds

Pless, L., Tracerco

Diagnosing liquid maldistribution problems inside packed beds that can cause mass transfer efficiency loss is a challenge to process engineers.

Does your control valve talk?

Almas, A., Palmela

Pneumatic operated control valves (POCVs) are consistently the most used control final element for process control across most industries—in some cases, they are also part of the safety instrumented systems (SISs) layer.

Considerations for revamping shell-and-tube heat exchangers

Garrido, E., Summum Projects

Revamp projects are complex in nature, and demand a great deal of resources for successful completion.

Revamp fired heaters with a common air-preheating system to increase capacity

Ahamad, S., Vallavanatt, R., Bechtel Corp.

In any process plant, fired heaters are generally considered to be one of the most optimally designed pieces of equipment.

Analyzing axial cooling fans’ high noise, vibration and failures

Allah, W. K., Saudi Aramco

Shipping pumps with 1,800 hp are equipped with five cooling fans that cool the oil going to the lube oil pumps to lubricate the bearings.

Role of simulation & testing in scaling-up new technologies

Andrew, Bob, Hydrocarbon Processing Staff

Design can be a challenging journey, starting with bench-scale reaction chemistry in a laboratory to a pilot plant, then building a demonstration facility, before commercially viable production facility can be confidently developed.

Improve H2O measurement in catalytic reformer H2 recycle streams

Engelhart, W. G., SpectraSensors

Catalytic reformer units convert naphtha into high-octane aromatic compounds called reformates, which are used in gasoline blending and formulation. UOP developed the catalytic reforming process and brought the first unit into operation in 1949.
