Enviro-Chem Engineered Turnkey Solutions
At Enviro-Chem, our capabilities encompass the spectrum of sulfuric and nitric acid plant design services and products. Over 50 years of experience is reflected in the high standards of the products and services that go in to each project and product. Serving our customers are over 250 experienced professionals offering the following services to acid industries:

Process Design:
The successful application of technology begins with the process design step. Years of practical experience greatly enhance the total design capabilities.

Using constantly updated computer modeling tools, our process engineers generate the conceptual design details for new plants, and are capable of studying the feasibility of capacity enhancements, energy conservation, and emission reduction.

Detailed Engineering:
Years of experience in acid plant design are the key to our successful engineering group. The continuous recording and upgrading of critical input have resulted in development of our Engineering Standards. Significant design quality and productivity improvements are offered via our Computer Aided Design (CAD) system.

With the added capability of 3D, we are able to model entire plants and customize the final product to meet the customers' needs more efficiently. Our detailed design capabilities draw from the talents and experience of our full range of in-house engineering design disciplines.

On-Site Construction:
Leonard Construction Company^®, our wholly-owned subsidiary, is an integral part of our project team from preliminary feasibility studies to start-up. This unique team approach assures conformity to design and project control procedures, resulting in shorter schedules, improved quality, and lower project costs.

The construction staff includes specialists in such key areas as acid brick and refractory installation, acid piping, vessel assembly, and process ductwork. A full-time construction group within the company ensures consistency and quality that are without equal in the industry.

Leonard Construction Company also maintains a very high priority on job site safety and is a leader among the construction industry with their safety programs and accident statistics. Leonard is a member of the National Constructors Association.

Project Management And Control:
Experienced project managers monitor and control every project from inception through plant start-up with support from project engineers, scheduling specialists, cost control engineers, expediters, buyers and construction engineers. Enviro-Chem has developed customized software to collect data from time sheets, purchase orders, accounts receivable, receiving reports, etc.

The consolidated input along with our extensive data base of experience on cost performance, productivity and progress gives the project team the capability to closely control costs, and adjust to schedule opportunities.

All aspects of the project are incorporated into a total project schedule from which major milestones are identified and closely monitored. Weekly project team meetings are held to analyze status, resolve the inevitable problems, and ensure that the team is moving in a cohesive direction.

Start-Up And Operator Training:
Start-up activities for a new or modified plant begins several months before construction is complete. Operating and start-up instructions are customized for the specific facility.

Included in the start-up planning and activities are: operator and supervisor training, both classroom and hands on, check-out of major equipment and control systems, debugging and commissioning of operational sub-systems, start-up support (around the clock if needed), debugging of equipment, instrumentation and procedures, and operational support until the entire process is brought up to the plant production rate for the performance demonstration.
