Hydrocarbon Measurement

Hydrocarbon measurement equipment is a critical piece for meeting contractual obligations as well as government regulations from the well head through all points of the hydrocarbon supply chain. The importance of accurate measurement has grown through the years and Chemex Global can meet your needs head on. Our team is experienced in building various types of equipment that accurately measures volumetric flow, pressure, and temperature to assess operational efficiencies or provide full details at custody transfer points.

Our experience is diverse, and our knowledgebase is deep, including positive displacement, turbine, ultrasonic, and Coriolis metering. We can assist clients in determining the most suitable type of measurement system for an application. In taking the time to understand the project as well as the process, products, output, and the degree of accuracy needed, Chemex Global can source a solution that meets all the needs.

Regardless of the application, Chemex Global can design and manufacture a variety of modular built measurement systems that can be trailer or skid mounted and easily transported to remote sites anywhere in the world. We can even design for applications where utilities and manned operation are not available, and instead can integrate power solutions from solar, wind or other sustainable energy sources as well as remote controlled systems.

Lease Automatic (LACT) / Automatic (ACT) Custody Transfer Systems

LACT and ACT systems can be used for a variety of locations and applications such as well sites, floating storage, and offloading (FSO) vessels, floating production storage and offloading (FPSO) vessels, terminals, pipelines, or other applications. Depending upon the specific application, these systems can designed with human machine interfaces (HMI) or with supervisory control and data acquisition (SCADA) and along with telemetry technology to enable remote control and monitoring from anywhere in the world.

Metering Systems

Metering systems can be designed with a variety of flow meters such as Orifice Meters, Positive Displacement (PD) Meters, Ultrasonic Meters, Coriolis Meters, and Turbine Meters.  Our systems are equipped with a Programmable Logic Computer (PLC) with HMI and instrumentation to conduct a variety of measurements with: Densitometers, Gas Chromatographs, or others for testing basic sediment and water (BS&W), temperature, and pressure. Our instrumentation can be pre-programmed to adjust calculations to compensate for differences in temperature, viscosity, and density to report details within any accuracy range dictated by local jurisdictional guidelines and industry standards (American Petroleum Institute’s (API),  Manual of Petroleum Measurement Standards (MPMS), or International Standards Organization (ISO) TC28 standards).

Integrated provers and samplers are standard.

Exemplary Project: Autonomous, Solar Powered LACT Unit

This project consisted of designing and manufacturing five meter runs to achieve accurate measurement from 500 – 90,000 bpd.  An integrated prover loop and sampling system were included in the design. This system is completely autonomous, remotely located on a nearshore manifold platform, remotely monitored and controlled with microwave communication link back to the inland flow station, and is powered by solar panels and associated battery system.
