The ENERGY EditionCHP Service/Repair Projects
Our client: A Maryland Wastewater Treatment Plant
About Our Client:This Water Treatment Department produced 2.0 billion gallons of drinking water in 2020 with an average daily usage of 6.1 million gallons with no Maryland Department of the Environment (MDE) or Environmental Protection Agency (EPA) violations. Their Water Quality department conducts quality testing on 12,500-plus samples of water and wastewater for treatment compliance each year and the Water Service team maintains 2,500 fire hydrants, 18,000-plus water meters, and 211 miles of water distribution mains and services up to private property lines. They have six water storage tanks plus 6.75-million-gallon capacity. At the plant, methane is produced during decomposition of waste in a digester. Being a hazardous gas and a by-product of waste treatment, it was previously burned off in a stack. This methane is now being utilized at the plant by powering a gas engine connected to a generator producing free electricity… AND the flue gas and combustion engine cooling waste heat is captured and used to heat the digester, eliminating another greenhouse gas.
About the Project: Our client had a combined heat and power (CHP) engine that had reached the end of its useful life and needed a replacement. Since we have experience with this type of project and service Liebherr Engines throughout the U.S., we were engaged to remove the current engine and replace it with a new engine. The replacement engine is a new Liebherr G9408 that runs with Biogas from a digester fed from the wastewater treatment operations.
We also committed to a Service/Maintenance Agreement to care for the equipment and ensure its operation for years to come. This includes monitoring, service, and all Preventive Maintenance services.
We just finished the 3,000 Hour Maintenance Service which includes, but is notlimited to: changing oil filters, performing oil analysis, changing oil separator media, changing spark plugs, adjusting valve clearances, cleaning air filters, checking coolant levels, save controller history and reset maintenance timers.
Our Client:An On-Site Power Provider
About Our Client:Our client is an Independent Power Producer focused on clean energy infrastructure assets.
This company develops, invests in, and manages sustainable infrastructure assets, such as renewable and waste to energy projects throughout North America. This includes the management of utility scale projects as well as the aggregation of smaller, “behind the meter” projects into portfolios. Our client has an extensive portfolio of distributed generation and grid-connected solar energy parks and wind farms in Europe and the Americas. About the Projects:Our client owns two energy plants in two separate hotels in New York City. The first plant is a 750kW combined heat and power (CHP) project that includes three (3) 250kW CHP units with high reliability. This plant reduces energy cost, increases resiliency, and reduces greenhouse gas emissions for the hotel by over 40% vs conventional energy generation. The second plant is a 500kW combined heat and power (CHP) project includes two (2) 250kW CHP units with high reliability. This plant also reduces energy cost, increases resiliency, and reduces greenhouse gas emissions for the hotel by over 40% vs conventional energy generation. Lima Company is providing routine maintenance for all five (5) CHP systems as well as 24/7/365 monitoring.
We performed an evaluation of all the engines to create a baseline for performance. This included measuring compression pressure in each cylinder, measuring engine crankcase pressure, identifying necessary spare parts for maintenance, and reviewing failure sequences. We performed routine maintenance which included oil changes, filter replacements, verifying condition and leak, age of the intake and exhaust system, verifying coolant levels and conditions, and oil pressure monitoring. Created a customized monitoring program that included: active monitoring with predictive failure analysis, continuous 24/7 data collection, detailed weekly report, notification of upcoming service intervals, and much more. One engine will be overhauled in December and a re-manufactured MAN E2842 E312 engine will be installed. All systems are working well, and we will continue to monitor and perform preventive maintenance to ensure continued reliability and efficiency.

Our Client:An International Consulting and Engineering firm
About Our Client: Our client is an international consulting and engineering firm that works with private and public sector clients to address new ventures and complex problems involving our environment, natural resources, and civil infrastructure. They have a combined staff of over 1,700 scientists, engineers, and related technical and project support personnel, they serve clients from more than 90 offices throughout the United States, Canada, United Kingdom, Ireland, Sweden, United Arab Emirates, and Australia.
About the Project: Our client is working for a large manufacturing company that has a parcel of wooded land that needs ground remediation. Our client’s Contaminated Site Practitioners guide their clients through a specialized remediation plan, consult on regulatory strategies, and develop a comprehensive cleanup approach. They can address numerous types of media, including contaminated soils, sediments, and groundwater. In this situation, the affected area was in the middle of the woods and the section required the surface to be paved with asphalt to aide in the remediation process. The issue in this remote area is the lack of power to energize the remediation equipment. So, Lima Company designed an on-site power generation system that will run on propane gas. This system will provide the energy to power all the remediation equipment, in island mode, for the duration of the project. Since the project duration is six to twenty-four months, Lima Company designed a rental agreement for the turnkey system to help ease the strain on their financial budget. The service also includes start up and commissioning, exhaust piping, HMI controls for operation, cellular monitoring bridge, LP gas connections and preventive maintenance for the duration of the project.
Our Client:Renewable energy solution company
About Our Client: Our client develops customized renewable energy solutions that are specifically tailored to solve each client’s unique requirements and needs with a focus on responsible use of natural resources and environmental protection. Their roots began in a company formed in 2008 which quickly established a reputation for providing quality services in the federal, state, and private sectors. From an initial operation of one employee this company grew into a corporation of now over 200 employees worldwide. The company specifically was born of a zeal to address growing challenges in our world’s handling of organic wastes and the need for sustainable clean energy. The company currently operates renewable energy projects in Virginia and Maryland with additional academic partnerships in New York and Pennsylvania. The parent company also conducts operations in seven states and four countries.
About the Project:This project is located on a farm that is contract grower for the fourth-largest producer of chicken in the United States. Each chicken growing cycle produces considerable accumulation of poultry manure, a waste stream which contributes to harmful nutrient runoff in the fragile Chesapeake Bay Watershed ecosystem when applied as a fertilizer to crops. To address the issues of waste accumulation and nutrient runoff, our client developed a customized Anaerobic Digestion System which was selected for funding by the Maryland Energy Administration (MEA) through both the Animal Waste to Energy and Combined Heat and Power (CHP) grant programs. Their solution reduces the concentration of three inhibitory nutrients in chicken manure prior to and during digestion leading to the effective and efficient conversion of manure into biogas while simultaneously making the digestate eligible to be used as a fertilizer within the nutrient restricted Chesapeake Bay Watershed. The biogas produced will be used to reduce the farm’s reliance on propane as well as to operate the Combined Heat and Power (CHP) engine supplied and installed by Lima Company as part of the renewable energy system which will generate electricity and heat for use on site. This biogas CHP system Lima Company designed includes: a micro-CHP unit powered by biogas, 50-gallon water heater, circulation pumps, piping, valves and expansion tanks, sensors for monitoring, exhaust piping and condensate lines.

AirGreen manufactures a novel and patented air conditioning and dehumidification system designed to provide superior comfort while also saving significant energy costs. Unlike traditional mechanical cooling systems, AirGreen uses a closed-loop liquid desiccant system to strip the moisture (humidity) from the air while also cooling it.
The AirGreen system has been designed to provide superior comfort at substantial lower operating costs. If humidity is an issue – this is where AirGreen’s performance really sets us apart. When compared to mechanical systems that overcool and reheat to control humidity, the
AirGreen technology can save up to 60% in cooling season energy costs. And because we are providing comfort with much drier air, the actual A/C setpoint can be raised a few degrees with no loss in comfort. Finally, our liquid desiccant cooling system also scrubs the air of pollutants, pathogens, and microbes, improving air quality and reducing the chance of mold formation – which can occur frequently when moisture and humidity are not controlled.
