The Importance of Effective Heating for Natural Gas Purification in Amine Plants

We are in the midst of a U.S. shale revolution: advancements in shale oil and gas extraction techniques have led to greater natural gas production levels and a renewed demand for natural gas in industrial and power applications. Because of the increased level of competition in the industry, process efficiency is paramount. Bringing natural gas to market cost effectively hinges on the optimal design and operation of the natural gas sweetening process.

STeBookNatural gas produced from reserves in almost never pure; rather, it contains acid gases such as carbon dioxide and hydrogen sulfide. One way to remove these impurities is amine gas treatment. An amine plant (also known as a sweetening plant) is used to remove the carbon dioxide and hydrogen sulfide from the gas solution so that pure natural gas can be efficiently transported to end users via pipeline.

Our latest white paper, Effective Heating Helps Amine Plants Purify Natural Gas, describes how to improve the natural gas purification process with effective heating. It also reviews the optimal conditions and system settings for controlling the amine regeneration temperature and optimizing the efficiency of the process.

The process works like this: the natural gas mixture and amine are combined in an absorber, where the carbon dioxide and hydrogen sulfide are removed. Pure natural gas exits from the top of the vessel and the amine is sent to a regeneration system (consisting of a still and a boiler) where it is filtered for reuse.

Usually, control and bypass valves are used to maintain a constant flow through the thermal fluid heater in the regeneration process. Moreover, the temperature of the system is typically controlled using overhead temperature measurements in the reboiler. There are a few problems with this standard procedure, which are described in detail in the eBook. If these problems are not addressed in the design of the control scheme, the process will not run optimally and the control systems could destabilize.

Using thermal oil as an indirect heat source can significantly increase the life of the amine solution and increase process efficiency. Typically, system operators manually set the flow of thermal oil through the reboiler. This is a convenient solution that prevents any need for frequent fine-tuning, but this conservative approach wastes energy. The eBook discusses the thermal fluid system specifications required to optimize the operation of amine plants.

Why You Should Stock Spare Parts for Your Heating System

Industrial facilities rely on a variety of equipment to support their vital processes. Factors such as increases in customer demand and exceptionally harsh applications can be taxing on the equipment, causing equipment malfunction or failure that takes production off-line.  For this reason it is imperative for facilities to keep the most crucial spare parts on-hand, preventing costly interruptions or shutdowns.

IMG_9674Many professionals tend to avoid the practice of stocking parts, but there are numerous benefits to this method. One such benefit is cost savings.  Assuming your plant is operating around the clock, you could potentially save thousands of dollars by having critical items readily available.

You should check to make sure that all the components of your Sigma Thermal heating system are in good working order for maximum performance and minimized interruptions. Part failures are common throughout industrial facilities; these issues often lead to extensive equipment downtime, which can range anywhere from a few days to several weeks.

skid-blogSigma Thermal warranties cover most damaged components, but due to the wide range of components we source, it’s difficult to have every item in stock.  Many of the parts have lengthy lead times—in some instances it may take up to ten weeks to receive the desired part. Our warranty can cover the replacement cost of the spare part, but what if you have start up technicians on-site? If you don’t have the necessary parts in stock, you will have to bear the cost of having technicians on standby until the replacement part is received.

Even if you are outside the warranty period, consider having spare parts on hand to help keep your heater running at optimal levels. If we have the part you need on the shelf, our team will gladly ship it via small package or freight service—next day or same day service is available in many cases.

No one wants to be held responsible for costly shut downs, so be sure to keep an adequate inventory of spare parts on hand.

Contact us today to make sure the spare parts you’re looking for are in our inventory.
