Compressors

Minimize engineering errors with competency and proper engineering review

Tharakan, J., Suncor Energy Products

Industry has seen numerous engineering errors during the commissioning phase of projects.

Troubleshooting the repetitive failure and shaft seizure of a hot oil circulation pump

The Shaybah NGL recovery plant has a single-stage, double-suction between bearings, radial-split design for hot oil circulation.

Optimize a refinery H2 network using spreadsheet tools

Salgado, H., Ecopetrol

One of the major goals in every refining complex is to minimize the utilization of its hydrogen (H2) generation units by maximizing the H2 recovery from residual streams.

Troubleshooting vacuum operation of an inter-after condenser unit in an ethylene plant

Wieslaw, T., Nichols, J., Sasol; Lieberman, N., Process Improvement Engineering; Johnson, E., Graham Corp.

A system of compressors powered by surface condensing steam turbines is inherent in the operation of a typical ethane cracker unit.

Reliability: Consider best available resources for reciprocating compressors

Bloch, Heinz P., Hydrocarbon Processing Staff

Whether it is compressor selection, upgrading, routine maintenance, major maintenance, failure avoidance or failure analysis: Realize that the reciprocating compressor procurement and improvement options available today are surprisingly advantageous compared to the options of 30 yr ago.

Upgrade process compressors to enhance production

Centrifugal compressors are production-critical equipment in refineries, petrochemical plants, and offshore oil and gas production facilities.

Burckhardt awarded modernization project at MOL petchem plant in Hungary

Burckhardt Compression was selected to modernize MOL Petrochemicals' third-party Hyper Compressor at its LDPE plant in Tiszaújváros, Hungary. The goal was to improve production performance and to establish a comprehensive, long-term service capability with a running-hours guarantee.

Equipment critical analysis: The need for an effective maintenance program

Zardynezhad, S., Toyo Engineering Canada Ltd.

Oil refineries and large petrochemical plants contain thousands of pieces of process and utilities equipment that are subject to wear, erosion, deterioration, aging, etc., resulting in increasing breakdowns and outages. Imagine being a maintenance engineer and receiving 50 work orders during an overhaul with a limited budget, time, labor, spare parts, tools, machines, etc. How does that engineer prioritize the work?

Editorial Comment: Maintenance—a value-added expense

Nichols, Lee, Hydrocarbon Processing Staff

This issue of Hydrocarbon Processing tackles one of the most integral aspects of the downstream industry (or any industry, for that matter): maintenance and reliability. These two terms go hand-in-hand and help to ensure efficient and safe operations.

Reliability: The risks of deferred compressor maintenance

Bloch, Heinz P., Hydrocarbon Processing Staff

At a recent conference attended by failure investigation professionals in San Antonio, Texas, a participant spoke about an explosion and fire event on a multistage horizontally opposed compressor in oxygen (O2) service. He had scant data, but he knew the machine did not have cylinder lubrication.
