Entech Engineering

What Entech Engineering does

Entech Engineering Inc. is a privately held environmental testing services company founded in March 1996 and headquartered in the Houston Clear Lake area (League City, Texas). The firm specializes in air emission testing and combustion performance evaluation for industrial stationary sources, operating twelve mobile emission laboratories that are deployed to client sites for on-site sampling and analysis. It serves heavy-industrial customers across the chemical, petrochemical, utility, cement, and metallurgical sectors, with named clients including BASF, Exxon Mobil, Chevron Phillips, and Bayer.

The company's core technical capabilities center on continuous emission monitoring systems (CEMS), reference-method testing, and combustion optimization, executed with analytical instruments such as GC/FID and FTIR. Service offerings include Relative Accuracy Test Audits (RATA), Leak Detection and Repair (LDAR), Title V compliance testing, CCSBT/PS performance evaluations, and combustion efficiency studies. The technical staff holds more than 90 years of combined experience in stationary source emissions work, led by President Billy T.Y. Lee, Technical Manager Edward Pasternak, and Laboratory Manager Steven Yin.

Entech operates a project-based professional services model in which mobile labs and field technicians are dispatched to industrial facilities for defined testing engagements, with revenue tied to per-project contracts under EPA, TCEQ, and LDEQ regulatory frameworks. International project work has been executed in Jamaica and the Netherlands, indicating capability beyond the U.S. Gulf Coast base. The company website copyright dates from 2008-2012, and no public funding rounds, M&A activity, or patent filings have been disclosed in available data.

Core offering

Entech Engineering provides on-site air emission and combustion performance testing services using twelve mobile emission laboratories equipped with EPA Reference Method compliant CEMS instrumentation. Service offerings include emissions compliance tests (NSPS, NESHAP, HON/MACT, TCEQ, LDEQ), CEMS certification (RATA, CGA), VOC testing, visible emissions observations, ambient air sampling, and combustion performance studies for industrial clients.

Product overview

Entech Engineering is an environmental testing services company offering a portfolio of air emission and combustion performance testing services. The company's core offering centers on twelve mobile emission laboratories (mobile test trailers) equipped with continuous emission monitoring systems (CEMS) for real-time monitoring of NOX, CO, CO2, SO2, O2, and THC. These mobile units integrate multiple testing modalities including emission sampling trains, sample handling and analysis systems, VOC testing, visible emissions observations, ambient air sampling, and various miscellaneous sampling techniques. The mobile test trailers serve as self-contained mobile laboratories providing flexibility for on-site compliance testing, emissions engineering studies, RATA, CGA, and combustion performance tests across industries including utilities, chemical/petrochemical, cement, and metallurgical sectors.

Functional benefit

Products and services

• Mobile Test Trailers Twelve sixteen-foot and twenty-foot mobile test trailers equipped with CEMS instrumentation for monitoring gaseous constituents (NOX, CO, CO2, SO2, O2, and THC). Self-contained mobile laboratories with mounted continuous monitoring instruments, sample handling systems, work areas for wet chemical analysis, and data acquisition systems, deployable to client sites with only power and sample-line connections required.
• Continuous Emission Monitoring Systems (CEMS) Services Continuous monitoring of NOX, CO, CO2, SO2, O2, and THC using chemiluminescence, NDIR/GFC, paramagnetic/ultrasonic, NDUV, and flame ionization analyzers, coupled with data acquisition systems. Serves industrial facilities that must demonstrate ongoing compliance with emissions regulations.
• Sample Handling and Analysis System Sample handling system capable of extracting one to 24 samples from flue or vent gas ducts, with heat-traced probes, condensation systems, filtration, and calibration using certified protocol gases. Supports multi-point, multi-parameter sampling for compliance testing.
• Emission Sampling Trains Over thirty variations of grab sample equipment consisting of probes, impingers, gas meters, and pumps for testing total particulate (RM 5/RM 17), SO2/SO3/H2SO4, HCl/Cl2, PM10, and multi-metals. Used for regulated manual source testing on industrial stacks.
• Volatile Organic Compound (VOC) Testing VOC testing services using GC/FID (EPA Method 18), Volatile Organic Sampling Train (VOST/EPA Method 0030), and Modified Method 5 (EPA Method 0010) for semi-volatile organics including dioxins and furans. Supports HRVOC vents, flares, and cooling testing for petrochemical and industrial clients.
• Visible Emissions Observations Visual opacity determination (EPA Method 9) using trained certified observers, and fugitive emissions observation (EPA Method 22) for continuous monitoring of emission visibility. Used by industrial facilities to comply with opacity and visible emissions regulations.
• Ambient Air Sampling Techniques Ambient air sampling for TSP, PM10, and PM2.5 using high-volume samplers and size-selective inlets with gravimetric analysis of particulate loading. Supports fenceline and perimeter monitoring for industrial sites.
• Miscellaneous Sampling Techniques Additional techniques including particle size distribution (cascade impactor), unburned carbon determination (LOI analysis), and multi-point flue gas temperature monitoring with thermocouple systems.
• Air Emission and Combustion Performance Testing Services Comprehensive testing services including emissions compliance tests (NSPS, NESHAP, HON/MACT, TCEQ, LDEQ), CEMS certification tests (RATA, CGA), combustion performance studies, NOx abatement studies, and fenceline/perimeter testing for utilities, chemical/petrochemical, turbines, cement, and metallurgical industries.
