Gas Engine Fueled By Graphene Byproduct

Graphene is the first and only two-dimensional material produced by man which is lighter, stronger, thinner, more conductive, more resistant and is a super-material that has limitless applications.

Like all manufacturing processes there is always a by-product and in our clients case the by-product was used as a fuel gas to run a 14kW gas generator. The generator has allowed them to remove their production equipment off the electrical network and in doing so reducing their electrical power costs.

The small 14kW generator was sourced from overseas and at first arrived with very little paperwork. Although through conversations with the OEM it was found that the generator package was tested and certified to UL2200 and the company was ISO 9001 accredited.

These pieces of information were able to be cross-referenced with AS 3814 Section 5.8 which is specifically for Stationary Gas Engines & Turbines

Clause 5.8.1 it states:

Gas engine and microturbine packages labelled up to 20 GJ/h that are in accordance with ANSI/UL 2200 are deemed to be in accordance with Clauses 5.8.2.3, 5.8.3.2, 5.8.3.4, 5.8.4 to 5.8.6, 5.8.10, 5.8.14 and 5.8.15.

NOTE: For conformity requirements for engine controls, see Clause 2.27.5.

These clause numbers refer to the following sections.

In addition to the above the control system also complied to Section 2.27.5 which outlines the basic control systems and safety instrumented systems using a PES

Control systems on OEM gas engines not exceeding 20 GJ/h are deemed to be in accordance with Clauses 2.27.5 and 2.27.6 provided that it can be established that they are—

(a) gas engine generator packages labelled in accordance with ANSI/UL 2200 and ANSI/UL 6200 (Outline of Investigation for Controls for Stationary Engine Driven Assemblies);

(b) gas engine generator packages labelled in accordance with ISO 8528-4;

(c) independently assessed by a competent person to demonstrate the gas engine driven assembly controls are in accordance with the relevant gas engine parts of ANSI/UL 2200 and ANSI/UL 6200 or ISO 8528-4; or

(d) proven in use as fit for purpose.

This demonstrated that the gas engine package was built and tested to those certification recognised in AS 3814 and could be directly mapped which allowed the Technical Submission to be developed. Although compliant with UL2200 it was still decided that an AGA approved SSOV and Low Pressure switch was to be fitted along with the other fuel train components upstream as per the requirements of an engine <5GJ/hr.

Although this is only a small scale project imagine the possibility’s in the future.
