Sealing Multiphase Pumping Applications

Wed, 25 Mar 2009 05:00:00

Multiphase – or “tri-phase”– pumping applications have been growing in recent years, due in part to the increase in oil extraction activity. But the flexibility and economic feasibility of multiphase pumps are also contributing to the growth. For example, in Canada, the drilling and refining of tar sands often requires the use of multiphase pumps, since the fluid stream can be a mixture of gas, liquids, and solids. And multiphase production leads to simpler, smaller in-field installations; reduced equipment costs; and improved production rates, making it economically appealing to upstream operations.

Sealing A Centrifugal Pump With Packing

Tue, 20 Nov 2007 05:00:00

In some cases, compression packing is used to seal light to medium duty pumps on applications that prove to be difficult for mechanical seals. The pump seal is formed by the packing being squeezed between the inboard end of the stuffing box and the gland. A common packing installation is shown in Figure 1 less the impellor. A static seal is formed at the ends of the packing rings and at the inside diameter of the stuffing box. The dynamic seal is formed between the packing and the shaft sleeve. Load applied to the packing deforms the packing against the shaft sleeve controlling leakage. Some leakage is necessary to cool and lubricate the packing. The amount of leakage will depend on the material of construction for the packing, operating conditions and the mechanical condition of the pump. The packing applied must be able to withstand the variables of the equipment such as runout, misalignments and thermal growth of the equipment without an appreciable increase in leakage.

The number of rings may vary from application to application depending on the objective of the sealing system. A lantern ring is used on most applications to introduce a lubricant to the packing. Packing rings from the lantern ring to the bottom of the box seal the fluid being pumped. The packing rings between the gland and lantern ring seal the lubricant used with the system.

How Condensate Kills a Seal

Thu, 30 Aug 2007 05:00:00

As today’s oil and gas industry continues to respond to the changing dynamics of a world economy, there is little argument that compressor reliability and uninterrupted operation are paramount and crucial to plant operation. One proven means to improve reliability is the integration of dry gas seal technology. Established as a solution for almost three decades on thousands of installed bases, the dry gas seal improves compressor and plant reliability, as well as product quality. However, the key to success is minimizing face contact for these seals. In many cases condensate causes these seals to fail, especially when a plant reliability team does not have a thorough understanding of the seal’s operating environment. Such challenges are typically avoidable though, with proper understanding of the scenarios that cause condensate.

Tips for Successful Retrofit of Wet Compressor Seals to Dry Gas Seals

Fri, 24 Feb 2006 05:00:00

Recognized as a useful substance for hundreds of years, natural gas is one of the main sources of energy for today's day-to-day needs and activities. And, with the increased focus on the environment, lean initiatives and sustainable solutions, natural gas continues to grow as a solution. Not only is it efficient, but natural gas is readily available, easy to transport, and most important — clean.

In response to its growing acceptance as well as environmental demands, power plants have integrated natural gas as a means to run their gas turbines, which in turn powers the generator in order to produce power — all in a clean fashion. Keeping other components — such as the all important compressor — free of contaminants is essential. As such, there is little argument that compressor reliability and uninterrupted operation are paramount and crucial to plant operation. Although there are countless vendors and compressor sizes continue to increase and their specifications advance, spare compressors simply aren't an option for most because of their cost. Further, operating requirements, such as pressure rating and speed, continue to expand beyond original intent, resulting in compressors being taxed beyond their design capabilities.

One means to improve reliability though is with the integration of dry gas seal technology. Proven as a solution for almost two decades on thousands of installed bases, the dry gas seal has been shown to improve compressor and plant reliability, as well as product quality. However, key to success in achieving optimum reliability is selection of the right dry gas seal and control system as well as a commitment to training and commissioning/operational procedures.

Meet Today's Split Seals: Advances in Technology Further Reduce Maintenance Costs and Ensure Reliability

Fri, 24 Feb 2006 05:00:00

The number of old pumps in operation today is staggering. Although the technology may be from yesteryear, these pumps found in the deep recesses of our factories to the far-reaching corners of our wastewater treatment plants continue to fulfill their critical mission. But, despite their longevity, many are plagued with frequent downtime and lost production. One growing trend to keep these older pumps in operation and out of extinction is the use of split seals.

The Organic Growth of Six Sigma at John Crane Inc.

Fri, 24 Feb 2006 05:00:00

It has been said that deployment is one of the most critical elements of a successful Six Sigma* program. From top-down support and Champion Training to awareness efforts targeting all employees, the deployment process for a company is a progression from which one input leads to an output that in turn leads to another input. However, simply completing each step does not guarantee a successful Six Sigma Program. Rather, key to success is affecting the very structure and nature of the organism itself. Such a distinction clearly separates those that "walk the walk" as compared to those whom merely "talk the talk."

Suitable Seals Lower the Total Cost

Thu, 21 Apr 2005 05:00:00

It is no secret that the cost of fixing pumps and related seal failure are among the highest recurring expenses in a maintenance budget. A recent study showed that one facility had repair costs of $1,600 for an ANSI overhung process pump every three to four months. At a minimum, this equates to $4,800 annually and $96,000 for the projected 20-year life of the pump. Consider the number of pumps in a typical process plant and this number grows exponentially extremely fast. The same study also found that the user of another pump reported a much higher repair bill for a single repair of $4,500; however, this pump needed repairs only every five years. This equates to $22,500 for the 20-year life, a savings of $73,500 as compared to the first pump with frequent, albeit less expensive, repairs.

Is It Time for an MTBR Standard?

Thu, 14 Apr 2005 05:00:00

In maintenance, just as in sports, you don’t know whether you are winning or losing unless someone keeps score. The “score” for many companies is the Mean Time Between Repairs (MTBR). However, unlike in a ball game, the MTBR score is subject to definitions and interpretation as other acronyms may be used to imply the same premise. Whatever the definition, using MTBR to track equipment reliability is an old idea. Although it was applied to refinery pumps in the early 1970s and described in reliability textbooks in the 1960s, it was probably used even prior to those instances. Today, “What is your MTBR” is a common question during roundtable discussions at equipment conferences. As such, is there a need for a “standard” definition of Mean Time Between Repairs? While a formal standard may seem unnecessary, it is important to note that MTBR is becoming both a benchmark and a contractual obligation. We’d like to use Pumps and Systems magazine to initiate a discussion on the definition of MTBR.
