I have found the answer from this post. Thanks to Marius for giving this answer.

First of all add this in any layout file, to load the editor in the config section:

<adminhtml_system_config_edit>
    <update handle="editor"/>
    <reference name="head">
        <action method="setCanLoadTinyMce"><load>1</load></action>
    </reference>
</adminhtml_system_config_edit>

Now create your own field renderer. It has to be a block inside your module:

<?php
class Namespace_Module_Block_Adminhtml_System_Config_Editor extends Mage_Adminhtml_Block_System_Config_Form_Field implements Varien_Data_Form_Element_Renderer_Interface{
    protected function _getElementHtml(Varien_Data_Form_Element_Abstract $element){
        $element->setWysiwyg(true);
        $element->setConfig(Mage::getSingleton('cms/wysiwyg_config')->getConfig());
        return parent::_getElementHtml($element);
    }
}

Now for the element inside the system.xml set the frontend_type 'editor' and the frontend_model your new block

<fieldname translate="label">
    <label>Field label </label>
    <frontend_type>editor</frontend_type>
    <frontend_model>module/adminhtml_system_config_editor</frontend_model>
    <sort_order>150</sort_order>
    <show_in_default>1</show_in_default>
    <show_in_website>1</show_in_website>
    <show_in_store>1</show_in_store>
</fieldname>

There are some issues when changing the config scope to a website or a store view. The textarea does not become 'disabled'. But if you can ignore this, you can use it without any problems.
