Industrial Utility Efficiency    

Technology

Turndown designates the operating range of an aeration blower or a blower system – and it can often be the most important factor in determining the ability of a system to match process demand. It is also critical to the system’s energy optimization. Unfortunately, in designing blower systems and controls turndown is not always given the attention that its importance merits. Here’s a look at the critical nature of turndown in wastewater treatment plants and recommendations for ensuring adequate turndown when utilizing Positive Displacement (PD) and centrifugal blowers.

Aeration Blowers

Sizing, selection, and adjusting control valves often causes confusion for process and control system designers. Improper valve application can cause operating problems for plant staff and waste blower power. Basing the airflow control system design on fundamental principles will improve valve and control system performance.

Industrial Blowers

Blower systems designed to deliver continuous airflow at pressures of 50 psig or below are critical to the operation of many processes including wastewater treatment, pneumatic conveying, fluid catalytic cracking, and fermentation to name a few. Many circumstances could arise that require an operator to require a rental blower for a period.

Rough Vac

Many heat-treating applications put difficult demands on vacuum pumps in general and oil-sealed pumps, in particular. Byproducts from the heat-treating process can contaminate the vacuum pump oil and create higher vapor pressures that cause deteriorated vacuum levels in the heat-treating chamber, or buildup and blockages in the pump mechanism.

Medium/High Vac

Distillation, degassing, drying, filtration, membrane separation, adsorption, and crystallization are all among the separation processes that rely on the differences in the physical properties of substances in a mixture. Distillation relies on the differences in boiling point or in vapor pressure versus temperature characteristics. Heating, evaporation, and condensing are the tools used in distillation that separate the liquid constituents in a liquid mixture.

Measurement

Every municipality and utility is facing the reality of rising energy costs. In 2010, the Town of Billerica, MA, which is located 22 miles northwest of Boston with a population of just under 40,000 residents, engaged Process Energy Services and Woodard & Curran to conduct an energy evaluation of the Town’s Wastewater Treatment Facility (WWTF) and pump station systems sponsored by National Grid. The objective of the evaluation was to provide an overview of each facility system to determine how electrical energy and natural gas were being used at the facility and to identify and develop potential costsaving projects.

Purification

Contamination such as humidity, oxygen or microbiological ingress can impact drug stability throughout the product life cycle. To prevent the risks of stability failure of highly moisture sensitive drugs (e.g. dry powder for inhalation), or the risk of biological ingress of parenteral drugs, highly sensitive integrity tests are required. Most test methods are very challenging in regards to time, effort, complexity or the limitation of sensitivity and detection range.

Vac Generation

Using suction cups and air-driven vacuum pumps is a preferable gripping and handling method of corrugated cardboard materials and boxes in carton-machines like case/carton erectors and rotary cartoners. Robot based applications, like palletizing and de-palletizing, are other examples where the best practice technology for gripping and handling is by suction cups and air-driven vacuum pumps.  
In the absence of official third party specifications on energy efficiency, it is difficult to evaluate and compare blower technologies fairly and effectively. The lack of readily available evaluation tools leads to misinformation and unfair comparisons between technologies. Further, the performance verification process is difficult to prove.
The plant air system consists of eight, single-stage, lubricated, Sullair rotary screw compressors. All units are in good working order.  Units 2, 3, 4 and 7 are water-cooled and units 6, 8, 9, 10 and 11 are air-cooled. The main plant air system has two primary compressed air dryers, a Thompson Gordon model TG 2000 refrigerated dryer, and a Sullair model SAR 1350 heatless desiccant dryer.  Both units are working according to their design. The TG 2000 uses approximately 11.2 kW and is a non-cycling type unit, and the SAR 1350 uses approximately 200 cfm of purge air to regenerate the wet tower. 
Triethylene glycol (TEG) dehydrators are the most prevalent technology for removing water vapor from natural gas . Molecular sieve dryers are also quite common in gas processing plants. Molecular sieve units have operating processes similar to industrial heat-regenerated compressed air dryers. Natural gas, however, often needs to be purified at the wellhead before reaching the processing plant. Deliquescent dehydrators are normally used, in remote locations where no power supply exists, to dry small gas volumes located between the wellhead and these main treatment plants. The most common applications are instrument gas, fuel gas, sales gas, and emissions mitigation.
When a submarine docks for maintenance, the Navy requires a high-pressure, dockside, pier-power air compressor ready to be used in an explosion-proof environment. We have technicians working on military ships and submarines worldwide. For this, both UAPC and some of our technicians have been prequalified and have different secrecy clearances depending upon the project. In addition to our rental air compressors, we also have a fleet of CNG compressors available for long-term rent for the CNG refueling market.
Compressed Natural Gas (CNG) is an alternative fuel source (to diesel and gasoline) with far-reaching benefits to North America. Strategically important benefits include energy independence, improved air quality, job creation, and lower and more stable fuel prices. This paper discusses natural gas desiccant dryer requirements in Natural Gas Vehicle (NGV) refueling stations, compares deliquescent to desiccant dryers and reviews two on-site field gas upgrading examples in displacing diesel fuel.

Two years ago, sales were picking up and we began operating six extrusion lines on most days. We had to bring in some portable chillers, to keep up, and we started looking at buying a larger cooling system. We wanted to get rid of the portable chillers and have room to grow into four more extrusion lines. The new system we looked at was a 100-ton system that would have cost us around $150,000 in capital and installation and with a larger monthly electricity bill. We were about to buy the new 100-ton chiller when our President, Abe Gaskins said, “Hold-on, can we replace the Liquid Ring pumps with something that doesn’t consume water”? That was our “Eureka!” moment.
The right ingredients and processes are essential for manufacturing flavorful beverages that contribute to the company’s bottom line. But what happens to all those other “ingredients” that aren’t part of the recipe? Cleaning up those unwanted ingredients from bottling plant wastewater can consume large amounts energy, time and money—and become a distraction from the company’s primary goal of manufacturing beverages.

When the Environmental Protection Agency was formed, in1970, it used its congressional mandate to issue all sorts of regulations regarding the discharge of contaminants into the land, water and air of this country. Over the years, air pollution has been one of the key areas where the Agency has put in place stringent requirements to control the emission of VOCs or Volatile Organic Compounds. Today the mandates of this government agency require extensive steps be taken to curtail their release by all operators of tank farms, chemical plants, refineries, fermentation plants and landfill operations. As a result of these regulations the Bio-Mass utilization industry was born.
