Navigating green pathways
In response to climate concerns, most countries around the world have goals to reach net zero by 2050. This means that all greenhouse gas (GHG) emissions produced are balanced by an equal amount of emissions that are eliminated. As a result, governments are establishing more stringent regulations to encourage companies to accelerate their decarbonisation efforts.
Valves Achieve Run Time Target in Demanding Omani Gas Gathering Application
Scenario Harsh operating conditions were limiting compressor valve run times at a gas gathering facility in Oman. With uptime limited to 4- to 8-week cycles, the operator was searching for a way to achieve a full 8,000 hours of operation with no valve failures. The operator chose to conduct a trial on one of its seven compressors, an engine-driven White Superior machine equipped with PEEK plate valves.
Gas Storage Facility Sets New Records for Valve Performance and Reliability
Scenario A gas storage facility in Texas operates a Chicago Pneumatic FE-665A reciprocating compressor working at 896 rpm to process gas reported to be 95% CO2. The facility has traditionally used an aftermarket plate valve purportedly designed for high-speed compressor applications. The customer’s primary concern is to enhance reliability and performance. Solution To help the customer reach the next level of compressor productivity, Cook Compression suggested the patented Ring Damped Valve.
High-Performance Manley® Compressor Valve Solves Problems for Natural Gas Storage Facility
Compressor valve problems not only reduce the reliability of a machine, but also can restrict the productivity of an operation. This was the case for a North American natural gas storage facility that was struggling with poorly performing valves in a two-stage Ingersoll Rand KVR compressor. The compressor has a 14-inch bore and 19-inch stroke. It operates at 335 rpm with a suction pressure of 720 psig and discharge pressure of 1,150 psig.
Redesign Extends RunTime for Hydrogen Chloride Compressor
A plant in France was struggling with rapid ring and packing wear on a hydrogen chloride compressor. The HCl compressor is a Burckhardt three-stage, tandem piston, non-lube vertical unit with discharge pressure of 30 bar (436 psi). Leakage across the piston rings and rapid ring wear were causing a reduction in the throughput of the machine. The customer had to replace rings and packing every 3 to 6 months.
Cylinder Clearance Tuning Yields Capacity Increase
Scenario Many Malaysian offshore oil and gas production platforms with gas lift/gas injection applications experience problems related to reduced flows as gas fields decline. On one platform, the operator called Cook Compression to assist their technical services group in assessing the mechanical reliability and performance potential of an Ariel JGK-4 reciprocating compressor. Their goal was to optimize compression to meet new flow requirements in the face of changing process conditions.
Custom-engineered Valve Tackles Varying Conditions at Gas Storage Plant
High speeds and variable operating conditions often result in a short life span for compressor valves and high operating costs for compressor operators. A leading North American pipeline and midstream company faced this situation and needed to find a way to get more life from their valves. The gas storage facility uses a White Superior WH-66 compressor for both storage and withdrawal, creating several sets of operating parameters for the valves.
Upgrade Boosts Unit Productivity Up to 30% at HMC Polymers Thailand Plant
Looking to capitalize on rising prices and demand for plastics, HMC Polymers Thailand was rushing to de-bottleneck a plant producing less than 200,000 metric tons per year of specialty polypropylene. Of particular concern was a compressor on line #1, a two-stage, lubricated Cooper unit used to recycle polypropylene gas. The run-time of the compressor was three to six months, roughly equal to the service life of the plant itself due to plugging of process equipment.
Stringent Emission Requirements? Not a Problem
In 2013, a customer on the West Coast of the U.S. approached Cook Compression to discuss how they could comply with the increasing emission regulations in the region. This was a critical issue to the customer, directly affecting their bottom line. Discussions between Cook representatives and the customer’s corporate office went on for years. During the final two years, the customer engaged its plant facility managers in identifying – and proposing solutions to – emission-related issues.
Field-Repairable Compressor Valve Improves Maintenance Logistics
Apache Energy Limited is an exploration and production company for crude oil, condensate and natural gas. Headquartered in Perth, Apache is active offshore Western Australia in the Carnarvon Basin. In 2003, Apache Maintenance Supervisor Bob Johnson was looking for ways to simplify compressor valve repair and improve reliability for three reciprocating compressors at Apache’s Varanus Island gas processing facility.
Expert Cylinder Repair Keeps SS Badger Steaming Across Lake Michigan
The SS Badger provides the largest cross-lake ferry service on the Great Lakes. The 410-foot steamship travels the 60-mile span across Lake Michigan between Ludington, Michigan and Manitowoc, Wisconsin, in four hours – about half the time it takes to drive around Lake Michigan through Chicago. It serves both commercial and recreational customers, carrying freight, vehicles, and up to 600 passengers. The Badger is the last coal-powered ferry operating on the Great Lakes.
