Abstract

The invention provides a method of utilising wastewater derived from a process selected from a group comprising a Methanol production process and a Methanol to Propylene (MTP) process, which method includes the step of conducting the wastewater to a saturator column of a Synthesis Gas Production Unit for saturating a hydrocarbon gas stream of the Synthesis Gas Production Unit.

Claims

AMENDED CLAIMS [received by the International Bureau on 09 November 2005 (09.11.05); original claims 1-8 replaced by new claims 1-7 (2 pages)]Claims
1. A method of utilising wastewater derived from a process selected from a Methanol production process or a Methanol to Propylene process, which method includes the step of conducting the wastewater directly to a saturator column of a Synthesis Gas Production Unit for saturating a hydrocarbon gas stream of the Synthesis Gas Production Unit.
2. A method as claimed in Claim 1, wherein the wastewater is used for saturation with any other water source.
3. A method of utilising wastewater derived from a process selected from a Methanol production process or a Methanol to Propylene process, which method includes the step of conducting the wastewater to a saturator column of a Synthesis Gas Production Unit for saturating a hydrocarbon gas stream of the Synthesis Gas Production Unit, wherein the wastewater is routed from a primary distillation section lo the saturator column.
4. A method of utilising wastewater derived from a process selected from a Methanol production process or a Methanol to Propylene process, which method includes the step of conducting the wastewater to a saturator column of a Synthesis Gas Production Unit for saturating a hydrocarbon gas stream of the Synthesis Gas Production Unit, wherein the wastewater is routed from upstream a primary distillation section to the saturator column.
5. A method of utilising wastewater derived from a process selected from a Methanol production process or a Methanol to Propylene process, which method includes the step of conducting the wastewater to a saturator column of a Synthesis Gas Production Unit for saturating a hydrocarbon gas stream of the Synthesis Gas Production Unit, wherein the wastewater is routed from both before a primary distillation section and from the primary distillation section to the saturator column.
6. A method as claimed in any one of claims 1 to 5, which includes the step of recovering water from synthesis condensate for use as boiler feed water. A method of utilising wastewater substantially as described and claimed herein.
