Multi-faceted approach on energy efficiency methods

The hydrocarbon processing industry (HPI) is a high-energy-consuming business. After cost for feedstocks, energy is the next largest operating expense for an HPI facility. Since the first oil embargo ..

Improve performance of exchangers in quench-water services

Lang, T., El-Hajal, J., Wieland-Werke AG; Provost, J., Technip

Dual-enhanced (DE) tubes are widely used in shell-and-tube heat exchangers (HEXs) in a range of industries. They have become a standard in multiple clean services for the hydrocarbon processing indust..

Automate furnace controls to improve safety and energy efficiency

Mickity, D., Phillips 66

Furnace firing is the biggest single operating expense in any refinery. Consider a medium-size refinery (250,000 bpd) that consumes 2,000 MMBtu/h. At a cost of $5/MMBtu, that’s $87.6 MM/yr being ..

BETE obtains ASME code certification for boilers, pressure vessels

BETE is the first spray nozzle company to obtain these ASME and National Board stamps.

Consider new steam system corrosion protection for refineries

Dale, T., Robinson, G., Rossi, A., GE Water & Process Technologies

New technology in volatile filming corrosion inhibitors and lower-salting neutralizing amines can provide cost-effective solutions for the steam-condensate system and minimize the risk of amine chloride salt formation.

Case study: Service life assessment of boiler superheater tubes

van Zyl, G., Al-Meshari, A., Al-Shahrani, S., SABIC Technology Centre

Boilers are used in petrochemical facilities to generate steam that can be used to meet process and utility requirements. Many industrial boiler designs can be shop assembled and are therefore referre..

Inspect steam reformers and catalyst tubes with infrared thermography

James, S., Thermal Diagnostics

Infrared thermography is a useful inspection tool to help locate problems in steam reformers while the units are online and fired. There are three main areas in a reformer that can be efficiently insp..

HP Water Management: Best practices for RO operations

Huchler, L. A., MarTech Systems, Inc.

Widespread use of reverse osmosis (RO) technology in industrial applications began in the late 1980s, following the introduction of polyamide materials that had a significantly higher permeate flow an..

Mitigate fouling in crude unit overhead—Part 3

Sloley, A. W., CH2M Hill

CASE STUDYThe basis for this case study is shown in Fig. 18; it is a crude unit with overhead heat integration. This is a one-drum overhead system with heat integration and no water wash. In an attemp..

Improve pressure drop calculations for saturated water lines

When saturated water flows through pipes and components, it flashes—thus increasing its specific volume and limiting the fluid flowrate. Due to these conditions, the calculation and design for pi..
